Abstract:

Abstract Background: Intra-abdominal hypertension is known as a factor affecting cerebral haemodynamics. Sustainably elevated abdominal pressure may disturb the balance of intracranial/blood pressure ratio, eventually developing perfusion pressure to drop. Aim: The aim of this study is to investigate the influence of artificially elevated intra-abdominal pressure upon brain pial vessels condition and contractile reactivity of isolated rat arteria carotis communis and vena jugularis to norepinephrine and serotonin. Materials and methods: The abdominal pressure of rats anaesthetized with xylazine 10 mg/kg and ketamine 100 mg/kg was increased up to 25 mm Hg by insufflation of air through venflon cannula and maintained for period of 1 to 3 hours. Craniotomy of left parietal area was carried out by micro drill. Open scull and cranial window techniques were applied. Outer diameters of superficial pial vessels were measured by USB digital microcamera (magnification up to 400x). Contractile reactivity of smooth muscle preparations from arteria carotis communis and vena jugularis of euthanized abdominal-hypertensive (AH) rats was registered isometrically. Results: Increased smooth muscle reactivity of a. carotis communis from AH rats to serotonin (10−8-10−4 mol/l) but not to norepinephrine compared to controls was registered. The changes tended to be higher in long lasting (3 hours) exposure of AH rats. Increase in outer diameter of pial vessels during maintenance of abdominal hypertension in both open scull and cranial window techniques was found. Conclusions: The increased intra-abdominal pressure causes dilatation of small superficial cerebral blood vessels and increases the smooth muscle reactivity of isolated arteria carotis communis to 5-HT.

Abstract:

Zusammenfassung Hintergrund: Schnitt-, Stich- und Schussverletzungen der Kopf-Hals-Region stellen aufgrund der hohen Gefahr von vaskulären Läsionen ein potentiell lebensbedrohliches Krankheitsbild dar. Ein konsequentes, standardisiertes Notfallmanagement, in der Regel assoziiert mit einer operativen Exploration, ist Grundlage der effektiven Rettungskette. Methoden und Patienten: 11 Fälle selbst- oder fremdverschuldeter penetrierender Verletzungen der Kopf-Hals-Region werden hinsichtlich Alter, Geschlecht, Verletzungshergang, Art der Verletzung, beteiligter Strukturen, diagnostischen und operativen Vorgehens sowie Outcome beschrieben und der aktuellen Literatur und Leitlinien gegenübergestellt. Ergebnisse: Bei 10 von 11 Patienten wurde, im Rahmen eines interdisziplinären Schockraummanagements, nach einer klinischen Untersuchung eine CT-Angiografie durchgeführt. Bei 9 dieser Patienten wurde daraufhin eine chirurgische Exploration und Wundversorgung vorgenommen. In je 2 Fällen waren die Arteria carotis communis, die Arteria carotis externa sowie große venöse Blutgefäße des Halses verletzt. Keiner der Patienten verstarb oder litt unter bleibenden Schäden. Schlussfolgerung: Eine rasche, systematische und fächerübergreifende Versorgung in speziellen Trauma-Zentren hat einen wesentlichen Anteil daran dass Patienten mit penetrierenden Verletzungen im Kopf-Hals-Bereich seltener an ihren schwerwiegenden Verletzungen oder deren Folgen versterben.

Abstract:

Os ramos do arco aórtico (Arcus aortae) em bubalinos foram investigados neste trabalho. Assim, foram dissecadas as artérias oriundas desse arco previamente injetadas com solução corada de látex Neoprene 650â (Du Pont do Brasil S.A.) em 20 fetos dessa espécie, machos e fêmeas com idades entre 4 e 8 meses de gestação. Em 80% dos casos, observou-se que o tronco braquiocefálico (Truncus brachiocephalicus) emite a artéria subclávia (Arteria subclavia) esquerda, artérias carótidas comuns (Arteria carotis communis) esquerda e direita, sem caracterizar tronco bicarotídeo (Truncus bicaroticus), e a artéria subclávia direita. As artérias subclávias direita e esquerda originam em comum o tronco costocervical (Truncus costocervicalis), a artéria cervical superficial (Arteria cervicalis superficialis), artérias axilares (Arteria axillaris) e artéria torácica interna (Arteria thoracica interna). Em 20% dos casos, o tronco braquiocefálico origina a artéria subclávia esquerda em comum ao tronco costocervical esquerdo; em seguida, emite a artéria carótida comum esquerda e termina trifurcando-se em artéria carótida comum direita, artéria subclávia direita e tronco costocervical direito, sendo que as artérias subclávias direita e esquerda têm origem comum com as artérias cervical superficial, axilar e torácica interna, com a presença do tronco bicarotídeo, característico dos bovinos.

Abstract:

Ein 29 Jahre alter Patient stellte sich nach einem Kollapsereignis sowie rezidivierender Schwindelsymptomatik vor. In der klinischen Untersuchung fielen ein Strömungsgeräusch über der Arteria carotis communis linksseitig sowie fehlende Armpulse beidseitig auf. Duplexsonographisch sowie MR-angiographisch und mittels brachiocephaler Angiographie wurden höhergradige Stenosen und Verschlüsse der extracraniellen hirnversorgenden Arterien dokumentiert. In der Labordiagnostik fielen lediglich eine beschleunigte Blutsenkungsgeschwindigkeit sowie ein deutlich erhöhtes C-reaktives Protein auf. Die rheumatologische Labordiagnostik hatte keinen auffälligen spezifischen Befund ergeben. Es wurde eine antiinflammatorische Therapie (Prednisolon), die mit einer immunsuppressiven Behandlung (Azathioprin) kombiniert wurde, eingeleitet. Bereits 12 Tage nach Therapiebeginn konnten duplexsonographisch und laborchemisch erste positive Therapieeffekte nachgewiesen werden. Bei Symptomen von Stenosen und Verschlüssen großer, vom Aortenbogen abgehender Gefäße (z.B. nicht tastbare Radialispulse), sollte differenzialdiagnostisch an das Vorliegen einer Vaskulitis gedacht werden. Die Takayasu-Vaskulitis ist insbesondere beim Fehlen typischer Vaskulitis-Marker von anderen Vaskulitiden abzugrenzen. Die MR-Angiographie hat sich in letzter Zeit als wertvoll in der Beurteilung der Wandbeschaffenheit der Aorta, ihrer Abgänge und anderer großer Arterien erwiesen.

Abstract:

Background: Recently, robotic systems have been introduced as a useful method for surgical procedures. But in the field of vascular interventional therapy, the development of robotic system is slower. Objective: The purpose of the study is to verify the reliability and safety of vascular interventional robotic system used in angiography, by the way of in vitro preliminary experiments and animal experiments. Method: The approach is to employ a proprietary vascular interventional robot system to complete glass vessel models and animal angiogram experiments. This robot system consists of a console port (remote steering system), an assistant port (propelled and rotation system) and a hydraulic fixing device, upon which surgeons control remotely to make go forward and rotate in the glass vessel models and animal vessels, on the 3D operation interface. Consequently, the operation time and success rate are counted and evaluated. Result: In the glass vessel model experiments, the Catheter can enter various kinds of vessel models with inside diameter length greater than 3mm and angle less than 90o. In the animal (adult dogs) experiments, surgeons can accomplish smoothly the angiogram of the renal artery, the vertebral renal and the arteria carotis communis, without any complications of surgery. Conclusion: The angiogram by using vascular interventional robot system is safe and reliable. Surgeons can finish the angiogram in part by remote operation, and the result of angiogram can meet a number of simple expectations. However without wire control and force feedback systems, the applicability of this kind of robot system is not flexible enough and need to be improved in the future.

Abstract:

Object Access to the upper thoracic vertebrae has been hampered by numerous anatomical structures and is further impaired by the transition from cervical lordosis to thoracic kyphosis. Therefore, the authors endeavored to study an anterior transsternal approach for upper thoracic disease (T1–4). Methods Fifty-four patients with upper thoracic disease underwent anterior decompression and fusion with sternotomy. Ages in the 33 men and 21 women ranged from 37 to 69 years (average 49 years). Before surgery, there were 7 patients with Frankel Grade B function, 17 with Grade C, 21 with Grade D, and 9 with Grade E. For a T-1 and T-2 lesion, the authors used “inside window of the brachiocephalic artery”: the brachiocephalic artery and right arteria carotis communis were retracted to the right, and the tracheoesophageal sheath was retracted to left. For a T-3 and T-4 lesion, the authors used the “outside window of the brachiocephalic artery”: the trachea, esophagus, and brachiocephalic artery were retracted to the left, the proximal portion of the right innominate vein was retracted to the right, and the left innominate vein was retracted inferolaterally. The patients were followed up for 24–48 months. Results The surgery was successful. The operation time was 120–150 minutes, and bleeding during the operation was 300–800 ml. After surgery, pain resolved in all patients, and improvement in motor deficits was noted in those who had presented with radiculopathy or myelopathy. Postoperative histological examinations showed that 33 patients had tuberculosis, 14 had metastatic neoplasm, 5 had eosinophilic granuloma, and 2 had traumatic fracture. Four patients died of systemic metastatic cancer between 10 and 21 months after surgery. There was no serious approach-related postoperative complication and no breakage of screws or failure of the internal fixation during follow-up. Conclusions Upper thoracic vertebrae can be exposed with sternotomy. This approach can provide excellent access to a lesion.

Abstract:

Diabetes mellitus is a global problem due to the increase of its prevalence, morbidity and mortality. Diabetes mellitus has chroniccomplications such as : micro vascular and macro vascular. The macro vascular complications reveal as atherosclerosis. The increase ofcarotid communist IMT was examined by using USG, which has become the standard for assessing atherosclerosis and recommended by theAmerican Heart Association. Fibrinogen levels have a role in atherosclerosis. This study was design cross-sectionals to know the associationbetween plasma fibrinogen with carotid communist IMT in patients with DM by special examination. The subjects were patients with DMcoming to Dr DR. Sardjito Yogyakarta and fulfil the inclusion as well as the exclusion criteria. The examination of fibrinogen was carried out by Claus’s method. The result showed positive correlation between plasma fibrinogen with carotid communist IMT in type 2 diabetes mellitus, r = 0.36 and p = 0.021. There is also positive correlation between age and carotid IMT with r = 0.314 and p = 0.048.

The symptoms are delayed and recurrent massive epistaxis. Angiography is the gold standard for confirming the diagnosis and visualizing the bleeding point. Endovascular interventions with depleted balloons and coils are effective treatment. Purpose: To report a case of massive epistaxis related to traumatic pseudoaneurysm of internal carotid artery. Case: A nineteen-years old male with sphenoid sinus injury caused by vehicle accident, which subsequently developed recurrent episodes of massive epistaxis for seventh month afterwards. He had undergone blood transfusion and nasal packing to control the bleeding. Nasal endoscopic examination showed blood clot in the superior meatus, while paranasal sinuses CT Scan showed isodense lesion in the right frontal and ethmoid sinuses, and bilateral sphenoid and maxillary sinuses. Cavernous segment of carotid communis artery entered into sphenoid sinus through a fracture line in the superior part of the sinus. Post arteriography and balloon embolization, there was no active anterior and posterior bleeding. Method: Searching for evidence produced 31 journals, and 10 journals were relevant to our clinical question. Result: From the 10 journals, 6 were case reports and 4 were researches of traumatic pseudoaneurysm of internal carotid artery which were treated by embolization. The results were good and complications were minimal. Conclusion: Traumatic pseudoaneurysm of internal carotid artery could cause massive epistaxis that requires a right clinical setting to diagnose, and embolization is the effective treatment to prevent mortality.Keywords: Internal carotid artery pseudoaneurysm, sphenoid sinuses trauma, massive epistaxis

Abstract:

Purpose: The aim of this study was measurement of artery intima media thickness (IMT) and plaques as an early indicator of atherosclerosis in diabetics comparing with other risk factors of carotid artery. Methods and Materials: 110 pts: 50 with Diabetes Mellitus, type 1 (25) and type 2 (25), 20 pts with glucose intolerance, 20 pts with type 2 de novo and 20 pts obese without diabetes. Ultrasound examination (using 7.5MHz sound on Toshiba SSA- 270A) end measurement of intima-media ticknes (IMT) were performed on Carotis communis (CCA), bifurcation and distal from bifurcation to a.carotis intern (ACI), expressed in mm. Plaques were correlated with other common factors age, BP, lipid parameters (Chol, HDL, LDL, Triglycerides), smokes, alcoholism and obese (BMI). The authors used 2 test and Spearman?s correlation . Results: The lowest percent of plaques was found in group with type DM 1. The highest percent of plaques was found in type DM 2. Statistically there is highly significant difference between plaques founded on type 2 DM and types 2 DM de novo and on other types. Conclusion: DM is not an independent risk factor for developing of macroangiopathic changes an arterial walls, but their appirience are more presenting in diabetic patients. The highest number of plaques are presenting DM type 2 (29.6%), and after type 2 de novo (26.8%), the next highest position of plaques were in patients with obese but without DM and intolerantio glucosae (IFG+IGT) (17.1%) and type 1 DM (9.8%). Risk factors were presented in following percentage : Obese 80.5% pts; hyperlipidema 53.7% pts; HTA 51.3%; smoking 51.2% pts and alchocholism 2.4% pts. According to these results, all risk factors were included in patophysiology of plack forming except alcoholism. Influences of these risk factors are very importance and their synergic action lids to their rapid appirience and clinical manifestations. DM has specific position in patophisiology of atherosclerosis.

Abstract:

: The circulus arteriosus cerebri of the porcupine was investigated in this study. Five porcupines were used. Coloured latex was given from the left ventricles of three and from the communis carotid artery of two porcupines. The circulus arteriosus cerebri was examined after dissection was done. The basilar artery was formed by a merge of the right and left vertebral artery. The caudal communicans artery which was the caudal part of circulus arteriosus cerebri was formed by the basilar artery on crus cerebri. From caudal to cranial, the branches originating from the basilar artery and circulus arteriosus cerebri to cerebrum and cerebellum were as follows: caudal cerebelli artery, media cerebelli artery, rostral cerebelli artery, caudal choroidea artery, artery which extended to the mesencephalon, caudal cerebral artery, internal ophthalmic artery, rostral choroidea artery, media cerebral artery, rami striati and rostral cerebral artery. The rostral cerebral artery dexter and sinister joined to each other by the rostral communicans artery, forming the circulus arteriosus cerebri. It was determined that the internal carotid artery did not participate in the formation of circulus arteriosus cerebri and the arterial blood to the circulus arteriosus cerebri of porcupine is provided via the basilar artery only.

Abstract:

Objectives to determine the hemodynamic changes within arterial vessels in different variants of extrasystole, to analyze whether extrasystole is an additional risk factor for the development of atherosclerosis. Material and methods. The study included 286 patients (175 men and 111 women) with extrasystole of more than 3000 per day and 88 patients with extrasystole of less than 3000 per day as a control group. When selecting eligible patients for the study, we tried to minimize the impact of traditional risk factors of atherosclerosis. The presence of cardiocerebral complications in medical history was also considered. The examination methods used in the study are electrocardiography, phonocardiography, 24-hour electrocardiography monitoring, Doppler ultrasound of the brachiocephalic vessels, lower extremities arteries, renal arteries, transthoracic or transesophageal echocardiography. Stress echocardiography was performed if indicated; as well as renal artery angiography, coronary angiography, computed tomography of the brain with angioprogram. When performing a biochemical blood test, the lipid spectrum and hemostasiogram were necessarily determined. All patients underwent left ventricular apexcardiography, as well as sphygmography, recorded on arteries of elastic type (a. Carotis communis) and muscular-elastic type (a. Tibialis posterior). The clinical examinations were confirmed and modeled using the original "Device for modeling of intra-arterial circulation", developed by us (RF patent No. 202780 dated 05.03.2021). Results. We determined an increase in the main parameters of the heart biomechanics and the kinetics of the main arteries in the 1st post-extrasystolic wave in patients with various types of extrasystole with the following pattern: the earlier extrasystole had appeared in the cardiocycle, the greater was the increase in the parameters under observation. A universal concept of hydraulic shock and possible cases of its formation were described. Conclusion. Extrasystole is an additional risk factor for the onset and progression of atherosclerosis. Hydraulic shock during the passage of the 1st post-extrasystolic wave is a powerful traumatic factor for the walls of the arteries, which can lead to the formation of an atherosclerotic process.

Abstract:

The aim – to improve the diagnosis efficiency of patients with arterial hypertension (AH) combined with undifferentiated connective tissue dysplasia (UCTD) based on the study of clinical course, the severity of UCTD external and internal symptoms with determining the levels of IL-1, IL-6, TNF-a, free and general blood oxyproline. Material and Methods. The study implied examination of 90 patients (52 women and 38 men) with AH of stage 2 from first to third degrees with manifestations of UCTD, who were on inpatient treatment in the Cardiology Department of the Lviv City Communal Clinical Emergency Hospital. The mean age of patients was (61.14±2.58) years. Patients were divided into 3 groups depending on the stage and degree of hypertension. Group I (n=16) included patients with hypertension of the first degree, group II (n=35) – with AH of the second degree, group III (n=39) – with AH of the third degree. The control group consisted of 20 patients with hypertension without manifestations of CTD. Patients underwent clinical (checkup, palpation, percussion, auscultation), laboratory (determination of IL-1, IL-6, TNF-a, free and general oxyprolin blood levels) and instrumental studies (ECG, echocardiography, DBPM, ultrasound examination of internal organs and vessels of the lower extremities, ultrasound duplex examination of the carotid and vertebral arteries, radiological examination of the osteoarticular system), consultations of an ophthalmologist, neurologist, traumatologist and dentist. Results. As a result of the study, in the group I of patients (n=16) UCTD of slight degree of severity was revealed in 13 (81 %), of medium degree – in 3 (19 %) persons. In the group II of patients (n=35), UCTD of moderate severity was found in 30 (86 %), severe – in 5 patients (14 %). In the group III of patients (n=39), UCTD of moderate severity was found in 32 patients (82 %), severe – in 7 (18 %). In the study of the level of TNF-a, an increase compared to the control group was detected, particularly, in the group I of patients its level exceeded in 37.4 times, in the group II – in 39.6 times, in the group III – in 46.2 times (p<0.001). IL-1b increased by 2.6-fold (р<0.05) in the group I of patients compared to the control group, 3.1-fold (р<0.01) – in the group II, and by 3.7-fold, that was the foremost (р<0.001), in patients of the group III. In turn, IL-6 in the group I of patients exceeded the indicators of the control group by 4.3 times (p<0.001), in the group II – 4.8 times (p<0.001), in the group III – 5.7 times (р<0.001). The study of the level of free oxyproline revealed its increase in comparison with the control group, namely in the group I of patients exceeded in 6.12 times, in the group II – in 6.81 times, in the group III – by 7.56 times (р<0.01). The study of the general of bound oxyproline revealed its increase in comparison with the control group, namely in the group I of patients exceeded by 6.98 times, in the group II – by 7.79 times, in the group III – by 9.42 times (p<0.01), which indicates an increase in fibrillogenesis and more pronounced destructive and inflammatory processes in connective tissue. Conclusions. Patients with AH of the stage 2 from first to third degrees with manifestations of UCTD have increased levels of IL-1, IL-6 and TNF-a, which are not only sensitive markers of inflammation, but also play an important role in the pathogenesis and progression of vascular lesions, occurrence and destabilization of atherosclerotic plaques and thrombotic vessels occlusion. The determination of blood oxyprolin in patients with hypertension combined with UCTD confirms the presence of CTD, namely the decay of collagen is more pronounced in patients with severe dysplasia.

Abstract:

Zusammenfassung Ziel Der Wert der intraoperativen Angiographie und deren Ad-hoc-Beurteilung im Hinblick auf operationstechnische Unzulänglichkeiten soll geprüft werden. Methode Insgesamt 523 konsekutive A.-cartotis-Thrombendarteriektomie(TEA)-Patienten mit intraoperativer Kontrollangiographie, postoperativer Duplexsonographie und retrospektiver Zweitbeurteilung der Angiographie wurden in die Auswertung einbezogen. Ergebnisse In der retrospektiven Zweitbeurteilung der Angiographie wurden 23 (4,4%) Verschlüsse oder hochgradige Stenosen der Arteria carotis communis (ACC) oder Arteria carotis interna (ACI) im Operationsbereich (12/2,3%) bzw. in der Abstrombahn (distale extrakranielle und intrakranielle ACI, A. cerebri media [ACM]) detektiert (11/2,1%), wohingegen bei der intraoperativen Ad-hoc-Beurteilung nur 13 (2,5%) derartige Pathologien beschrieben worden waren (7/1,3% im Operationsbereich, 6/1,1% in der Abstrombahn; p=0,002). Duplexsonographisch wurden postoperativ bei 50 von 505 untersuchten Patienten (10,1%) operationstechnische Unzulänglichkeiten lokal detektiert, was signifikant mehr war als in der Angiographie (p<0,001). In den meisten Fällen handelte es sich um nicht okkludierende/nicht hochgradig stenosierende Intima-Media-Ablösungen (19), Nahteinziehungen (13) und Kinkings/Kalibersprünge am distalen Patchende (14). Nahteinziehungen und Kinkings/Kalibersprünge waren mit einer linksseitigen TEA (adjustierte OR: 2,4; 95%-KI: 1,1‑5,1), einer Operation ohne Patch (adjustierte OR: 16,6; 95%-KI: 1,3–215,0) und der Verwendung eines Dacron- vs. Polytetrafluorethylen-Patch (adjustierte OR: 3,0; 95%-KI: 1,4–6,6) assoziiert. Schlussfolgerung Bei der Ad-hoc-Beurteilung der intraoperativen Kontrollangiographie kann eine nicht unerhebliche Zahl auch okkludierender und hochgradig stenosierender Pathologien übersehen werden (zur Detektion nicht okkludierender und nicht hochgradig stenosierender operativer Unzulänglichkeiten methodisch nicht geeignet – Ausweich: postoperative Duplexsonographie).

Abstract:

Autologous vein grafts used as aortocoronary bypasses are often prone to intimal hyperplasia, which results in stenosis and occlusion of the vein. The aim of this study was to prevent intimal hyperplasia using a newly developed perivascular system with sustained release of sirolimus. This system of controlled drug release consists of a polyester mesh coated with a copolymer of L-lactic acid and ε-caprolactone that releases sirolimus. The mesh is intended for wrapping around the vein graft during surgery. The mesh releasing sirolimus was implanted in periadventitial position onto arteria carotis communis of rabbits, and neointimal hyperplasia was then assessed. We found that implanted sirolimus-releasing meshes reduced intima thickness by 47±10 % compared to a vein graft after 3 weeks. The pure polyester mesh decreased vein intima thickness by 35±9 %. Thus, our periadventitial system for controlled release of sirolimus prevented the development of intimal hyperplasia in autologous vein grafts in vivo in rabbits. A perivascularly applied mesh releasing sirolimus is a promising device for preventing stenosis of autologous vein grafts.

Abstract:

Objective: Monitoring of vessel perfusion is of high clinical importance in vascular anastomosis of free flaps. Current sensor systems are based on different principles and show limitations in validity and accuracy. Fiber optic pressure sensors exhibit high accuracy and are small in size. The aim of the present study was to evaluate the surgical feasibility of intraluminal pressure (ILP) measurements with a fiber optic pressure sensor in an animal model.Methods: In a microsurgical setting we sedated 10 Wistar rats with weight adapted phenobarbital, xylazine, and fentanyl. We performed a surgical approach to A. carotis communis and V. jugularis and introduced a 600 μm fiber optic pressure sensor into the vessels followed by measuring the ILP. The sensor was stabilized by the surrounding tissue, and the vessels were closed.Results: In all cases, surgical placement was uneventful. Measurement of intra-venous and intra-arterial pressure was possible and stable over the whole measurement period of an hour.Conclusion: Fiber optic pressure measurement in microvessels is possible and surgically feasible. An application to monitor the perfusion of free flaps seems possible.
