Abstract:
Introduction: Identifying left aberrant hepatic artery during gastrectomy for cancer is occasional. In case of replaced left hepatic artery, its ligation can lead to hepatic injury or ischemia, while preserving it can cause difficulties during lymphadenectomy. In literature there is no consensus regarding preserving replaced left hepatic artery during gastrectomy for cancer. A recent study, analysing adverse effects of ligating an aberrant left hepatic artery, shows in pacients with over 5 times elevated transaminase levels, increase in hospital length and postoperative complications. On the other hand, there are studies that consider ligation of aberrant left hepatic artery safe, the only inconvenient being postoperative transient elevation of transminase levels, when ligated artery diameter is over 1.5 mm. Matherial and methoods: We report the case of a 65 years old male, known with myocardial infarction, admitted for epigastric pain, nausea, vomiting, dysphagia for solids and important weight loss. Upper gastrointesinal endoscopy with biopsy and computed tomography showed eso-gastric tumoral mass, signet ring cell carcinoma, no metastases. Intraopertive, we found replaced left heaptic artery arising from left gastric artery, close to the celiac trunk, its diameter being approximately 1 cm. Total radical D2 gastrectomy with mechanical eso-jejunal Roux-en-Y anastomosis was performed. Postoperative evolution was favourable surgically, but the patient had SarsCov2 infection during hospitalisation The final pathology report showed 18 lymph nodes examined, 5 being with adenocarcinoma metastases. Conclusions: Preserving replaced left hepatic artery during gastectomy for cancer is preferable, lyphadecnectomy not being affected. Potential postoperative complications resulted from ligation of replaced left hepatic artery could have chanced the prognosis.

Abstract:
AIM: Aberrant hepatic artery is particularly common, and its diversity and complexity play a critical role in surgery. The aim of this study was to describe the incidence and type of aberrant hepatic artery, and to compare differences in transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) with vs without aberrant hepatic artery. METHODS: This was a retrospective study of patients with HCC who received TACE at the same intervention center between March 15, 2020 and December 31, 2022. All patients who met inclusion criteria were divided into two groups based on whether or not they had aberrant hepatic artery. The aberrant hepatic artery was systematically classified according to variations in origin. We compared differences in baseline characteristics, operation duration, and postoperative hospitalization between the two groups. Postoperative adverse events and laboratory data were also compared. RESULTS: A total of 1250 patients hospitalized with HCC were included in the study (mean age, 58 ± 10 years, 1019 [81.5%] males). A high incidence of aberrant hepatic artery was found during TACE (21.3%, 266 of 1250), mainly involving a single variation of the aberrant left hepatic artery (aLHA) (6.1%, 76 of 1250) or aberrant right hepatic artery (aRHA) (10.9%, 136 of 1250) origin, as well as complex variations of the aLHA and aRHA origin (2.4%, 30 of 1250). When comparing patients with vs without aberrant hepatic artery, the TACE operation duration was significantly different (p < 0.001), and tended to be greater for patients with aberrant hepatic artery. In addition, differences between aberrant and normal hepatic artery groups in postoperative nausea and vomiting were statistically significant (40.2% vs 30.8%, respectively, p = 0.004). Postoperative laboratory examinations revealed significant differences in aspartate aminotransferase, alanine aminotransferase, and neutrophil percentage between the two groups (p < 0.05). CONCLUSIONS: The incidence of aberrant hepatic artery is extremely high, and the condition is characterized by complex variations. Moreover, aberrant hepatic artery may have a critical impact on the course of TACE treatment.

Abstract:
The Abdominal aorta and its major branches supply oxygenated blood to nearly all the organs in the abdominal cavity. During routine dissection (January 2009) of a middle aged male cadaver at Dr. PSIMS, Gannavaram, Krishna Dist. (INDIA), the following variations of branches of abdominal aorta were found. The coeliac trunk gave off three branches. The first branch was left inferior phrenic artery which arose directly from coeliac trunk. The second branch bifurcates into left gastric artery and accessory hepatic artery for left lobe of liver. The second branch gave off splenic artery and common hepatic artery. The right testicular artery took its origin from right aberrant renal artery. This variation was associated with the presence of bilateral aberrant renal arteries for lower poles of both kidneys arising from abdominal aorta and aberrant renal arteries bilateral for upper poles originating from the renal arteries. Anatomical variation of testicular arteries is reported to be 4.7 %. Apart from creating hazards during abdominal surgery, vascular variation can also become a technical problem for infusion therapy and chemoembolisation of neoplasm in the liver.http://dx.doi.org/10.3126/kumj.v9i1.6268 Kathmandu Univ Med J 2011;9(1):72-6

Abstract:
The high incidence of hepato-biliary vascular anatomy variations necessitates its evaluation prior to performing liver transplantation, hepatobiliary, pancreatic, gastric and oesophageal surgeries. We report a unique case of persistence of embryonic arteries of the liver, wherein, the liver was supplied by five vessels. In addition to the usual right and left hepatic arteries from the hepatic artery proper, the liver received two accessory right hepatic arteries, one from the gastroduodenal artery, while another arising from superior mesenteric artery and an accessory left hepatic artery, from the left gastric artery. The origin of gastroduodenal artery was found to be unusually high and its abnormal anterior course over the common bile duct further added complexity to the hepatobiliary anatomy. The presence of these aberrant and accessory arteries predisposes to inadvertent injury leading to patient morbidity and sometimes mortality.

Abstract:
Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.

Abstract:
This is the case of a 6-month-old boy who is diagnosed with, and treated for, a vascular ring, following several admissions to paediatric intensive care with difficult respiratory symptoms and ongoing failure to thrive. This case highlights the diagnostic challenge presented by these patients. Cardiovascular causes of paediatric airway compression are often under-recognized, with consequent delay in diagnosis. Although they are much less common than other causes of stridor, such as laryngomalacia or other tracheo-bronchial anomalies, chronic airway compression in childhood from vascular malformations carries significant morbidity and mortality. It is readily treatable and should not be overlooked. A high index of suspicion for mechanical compression should be maintained in small children with recurrent obstructive respiratory signs and symptoms or the older child presenting with dysphagia. The most prevalent vascular anomalies resulting in airway compression are a double aortic arch, right aortic arch with an aberrant left subclavian artery, innominate artery compression, left aortic arch with an aberrant right subclavian artery (rarely), and pulmonary artery sling. Rarely, complex congenital heart disease, itself leading to dilatation of the cardiac structures, may precipitate airway compromise, as in tetralogy of Fallot with an absent pulmonary valve syndrome or conditions with significant atrioventricular valve regurgitation causing left atrial enlargement. A dilated ascending aorta may compress the trachea, producing similar symptoms likewise with a cervical aortic arch with an aberrant sublclavian artery and ipsilateral ligamentum arteriosus. Such cases require a comprehensive diagnostic workup. Investigations include plain chest X-ray, echocardiogram, direct microlaryngoscopy and bronchoscopy, and CT angiography or cardiac MRI. A normal laryngoscopic examination should warrant further investigation in the presence of ongoing symptoms. An appreciation of aortic arch embryology is important in interpreting echocardiography and cross-sectional imaging in relation to the role of airway compression. Management often necessitates multidisciplinary collaboration among specialties, including ear, nose, and throat (ENT) specialists, paediatric cardiologists, respiratory physicians, intensivists, and cardiothoracic surgeons. Definitive treatment depends on the underlying pathology but usually involves surgical decompression or aortopexy. A proportion of patients will continue to exhibit symptoms following surgical release, due to ongoing weakness of the airway, and in severe cases may require ongoing respiratory support.

Abstract:
Abnormal aorta and aortic branching discusses congenital variants of the aortic arch and great vessel branching. While many of these anomalies are incidental imaging findings in asymptomatic individuals, lesions such as a double aortic arch and right aortic arch with aberrant left subclavian artery produce vascular rings which can cause respiratory or esophageal symptoms. Certain anomalies such as a right aortic arch with mirror image branching are very frequently associated with other congenital cardiac abnormalities. Another common aortic congenital abnormality that may be diagnosed in early adulthood is aortic coarctation, frequently manifesting with upper extremity hypertension. As many of these lesions are first detected on chest radiography, the radiographic appearance and classification of these abnormalities is discussed in detail and supplemented by additional information that can be obtained with CT and MR.

Abstract:
Abstract Liver transplantation is the treatment of choice for end-stage liver diseases and hepatocellular carcinoma. Living donor liver transplantation, in an era of organ shortage and a large number of candidates, can be an additional source of grafts and, in selected cases, can be considered to be the technique of choice. Donor selection, with a step-by-step approach, is crucial for the safety of the donor and the good outcome of the recipient. Left or right donor hepatectomy, performed in an open, laparoscopic, or robotic fashion, is demanding. Some important technical aspects have to be considered before and during the surgical procedure, especially in the biliary tract dissection and graft venous outflow. Complex reconstructions for the venous outflow, the portal vein, the hepatic artery, and the hepatic duct may be necessary. In this context, additional tools to help the surgeon planning the surgical strategy are under evaluation.

Abstract:
Evaluating the adrenal gland with imaging can be challenging. The adrenal glands may be morphologically within normal limits even in the presence of clear hyperfunction. Hyperplasia and small nodules may coexist. Nonfunctioning nodules are frequent and need to be differentiated from culpable hyperfunctioning adenomas or carcinomas. However, the increasingly sophisticated anatomical imaging provided by CT and MRI, together with the functional characterization afforded by radionuclide imaging, allows good correlation with clinical and endocrine parameters. Embryologically, the adrenal cortex derives from coelomic mesoderm and the medulla from neural crest cells. Development is independent of the kidney and adrenal glands will normally be present in the absence of a kidney. In the newborn the adrenal glands are large structures, being one-third of the size of the kidneys. They involute rapidly, however, and in the adult are small structures. They are situated immediately above and anteromedial to the upper pole of the kidneys, although the left is less suprarenal. The right lies immediately behind the cava, alongside the right diaphragmatic crus. The left lies behind the splenic vein, lateral to the left crus. The normal adrenal has a characteristic inverted Y- or V-shape with the two limbs fusing anteromedially. The most cranial section has a triangular appearance. Cross-sectional appearance varies according to the exact level. Each limb measures 2.5–4 cm in length and 3–6 mm in thickness. Greater than 1 cm thickness is definitely abnormal. Accessory adrenal tissue (rests) may be found in the kidney, testis, or ovary, and elsewhere in the retroperitoneum. Arterial supply is from three sources: superior–multiple arteries from the inferior phrenic; middle from the aorta; and inferior from the renal artery. A single vein drains each adrenal. The left is a tributary of the left renal vein, the right leads directly to the cava, although rarely may join a hepatic vein first. The right adrenal vein is shorter and narrower.

Abstract:
The incidence of cirrhosis, the end stage for many liver diseases, is rising and with it the need for better understanding of the progression of the disease and diagnostic techniques. The authors have noted that liver disease occurs preferentially in the right side of the liver which is the largest lobe. One hypothesis is that this is due to the composition of the blood that supplies the right lobe. The liver is fed by both the hepatic artery and the portal vein with the portal vein contributing about 80% of the blood supply. The portal vein (PV) is supplied by the superior mesenteric vein (SMV), which drains blood from the digestive track, and the splenic vein (SV), which drains blood from the spleen. Since the blood in the SMV is coming from the digestive track, it carries toxins and items absorbed during digestion. Toxins such as alcohol are known to damage the liver. Thus, our hypothesis is that the majority of the SMV flow feeds into the right portal vein and ultimately the right lobe of the liver. This study seeks to assess the validity of our hypothesis in four subjects by creating subject specific models in two normal subjects and two patients and using computational fluid dynamics (CFD) to calculate the SMV contribution to the right portal vein.

Abstract:
Mechanical circulatory support devices have gained significant importance in recent years as a viable therapeutic option to support paediatric population and children with single functional ventricle. The Fontan operation helps to reroute the deoxygenated blood to the lungs by bypassing the dysfunctional right ventricle. Total Cavopulmonary Connection (TCPC) is usually a method opted by the clinicians to connect the superior vena cava (SVC) and inferior vena cava (IVC) to the left and right pulmonary artery (LPA and RPA). However, the non-physiologic flow patterns created by the Fontan procedure leads to an increase in chances of platelet deposition and pressure loss which calls for heart transplantation to prevent early and late stage pathophysiology. This had led to modification of TCPC geometry to reduce the pressure and energy loss and thereby unload the single functional ventricle to ensure longer survival period. A study on mechanical circulatory device in conjunction with the modified TCPC geometry has seen little exposure and has opened new gates to develop a variety of state-of-art cavopulmonary assist devices. This study is focused on the selection of optimal TCPC to reduce energy loss and the effect of stent inside the modified TCPC on hemodynamics and flow structures. Four TCPC connections, developed for a particular age group of children, were studied for the velocity field, overall pressure and energy loss. In addition, the four TCPC connection geometries were also studied for distribution of hepatic blood from the IVC to both pulmonary arteries, and hence the lungs, to prevent development of any arteriovenous malformations. The entire stent assembly mounted inside the two best performing TCPC connections was examined for the hemodynamic effects using a series of 3D-CFD simulations. The curved-type connection for the TCPC proved to provide minimum pressure and energy loss along with reduced traces of vortex and recirculation. However, it was not efficient in terms of hepatic blood distribution. The flared geometry performed second best in terms of both minimum power loss and even hepatic blood distribution. There was a slight difference in power loss between the flared and the curved TCPC configuration with stent but the flared geometry had better hepatic blood distribution. This study demonstrated that a stent in conjunction with a TCPC leads to development of a helical flow pattern which provides better mixing of blood and even distribution to both the pulmonary arteries. The design of a stent with the best performing flared TCPC configuration can be optimized to reduce the amount of power loss and vortex generation and can be used to design similar scaled models for paediatric population of various age groups.
