Abstract:

AbstractBackground:During neck dissection, the current practice is to preserve the internal jugular vein in the majority of cases. However, sacrifice of bilateral internal jugular veins is required in rare cases. Simultaneous excision of both internal jugular veins is known to frequently cause fatal complications. Even if staged, bilateral internal jugular vein sacrifice still occasionally leads to fatal complications (in 2 per cent). We report two different methods of unilateral internal jugular vein reconstruction, in two cases requiring excision of bilateral internal jugular veins, and we r

Recurrent venous reflux in the popliteal fossa of patients with recurrent varicose veins following short saphenous vein surgery was assessed in 70 limbs using a duplex scanner.

The recurrence or persistence of the short saphenous vein was subdivided into four types: an intact saphenopopliteal junction, as well as an intact short saphenous vein in 20 limbs (type I); varicosities in the popliteal fossa communicating with a short saphenous vein stump in 11 limbs (type II

Abstract:

Background: Portal vein drains blood from the abdominal part of alimentary tract, spleen, pancreas and gall bladder to the liver. It is normally formed by the union of superior mesenteric and splenic veins behind the neck of pancreas. Knowledge of variations regarding the formation of portal vein is very useful for surgeons to perform pancreas and duodenum and liver surgeries and for the interventional radiologist for catheter-based interventions. The objectives of this study are to disclose the variations in formation of hepatic portal vein and to measure the length of portal vein in cadavers

Type A is classified as a high fenestration joining to make a single entry into the subclavian vein. Type B is a duplication from just below the jugular foramen to the subclavian vein.

Abstract BACKGROUND The superior thalamic vein (STV) was first described comprehensively by Ferner in 1958 as the most prominent thalamic vein; it originates from the central superior portion of the thalamus, coursing medially to the third ventricular thalamic surface, where it turns posteriorly to parallel the internal cerebral vein (ICV) before ending into its posterior portion. Since historical anatomic and angiographic studies in the pre-computed tomography (CT)/magnetic resonance imaging era, the STV has not been investigated.

Methods: Descriptive cross-sectional study, performed at Dong Nai General Hospital from May 2023 to May 2024. The research subjects were cases of venous insufficiency diagnosed with Doppler ultrasound. The reflux patterns of great saphenous vein insufficiency are classified into 4 types as follows: type 1, reflux in both the ankle and saphenofemoral junction; type 2, ankle r

Abstract:

OBJECT The drainage of the superficial middle cerebral vein (SMCV) has previously been classified into 4 subtypes. Extradural procedures and dural incisions during the anterior transpetrosal approach (ATPA) may interrupt the route of drainage from the SMCV. In this study, the authors examined the relationship between anatomical variations in the SMCV and the corresponding surgical modifications to the ATPA that are necessary for venous preservation. METHODS This study included 48 patients treated via the ATPA in whom the SMCV was examined using 3D CT venography. The drainage patterns of the SM

Abstract Fluid inclusion study is carried out on the vein and bedded-type barite of the Proterozoic Cuddapah basin of Andhra Pradesh. In the case of vein barite, primary inclusions are mostly monophase and liquid-rich biphase (L+ V), with their freezing temperatures indicating their composition as H2O+NaCI±KCl and density of the ore forming fluids as 0.901 to 0.944 g/cm3. The primary liquid-rich biphase (L+V) inclusions of the hydrothermal vein barite shows homogenization temperatures in the range of 230° to 260°C.

Objective. To determine the optimal level of intersection of the pancreas based on the features of the topography of the arterial vessels and the pancreatic duct of the isthmus and the body of the pancreas. Methods. 44 complexes of the upper floor of the abdominal cavity were studied. An injection mass with the subsequent fixation complexes in a formalin solution was introduced into the arterial vessels. The pancreatic tissue was crossed over the superior mesenteric vein along vertical lines drawn on one, two, three, four, and five cm to the left of the superior mesenteric vein. Depending on t

Highlights Abstract Superior vena cava (SVC) syndrome with central thoracic vein occlusion associated with the use of intravascular devices is increasing and involves younger patients. Hemodialysis patients are at higher risk for central vein occlusion and symptomatic SVC syndrome. It is imperative to preserve venous access, particularly for younger patients who will rely on dialysis for an extended duration. Endovascular venous reconstruction is the recommended treatment but there are not standardized guidelines about the type of stent and technique. In the present case report the primary obj

Objective Venous malformation (VM) is a common vascular malformation in soft tissue. Its morphological and draining features, relationship with main vein, and hemodynamics in the lesion are not completely clear till now. Above information is important for choice of treatment. Methods From January 2012 to December 2013, 23 patients were enrolled into this study. Percutaneous puncture into the lesion was made and contrast media was injected into venous sinus. Immediately after that CT scan was performed, and repeated several minutes later. Then three-dimensional imaging was performed to show the

Abstract:

The portal vein (PV) is a major vessel that supplies blood to the liver and is formed by the union of the superior mesenteric vein (SMV) and the splenic vein (SV) behind the neck of the pancreas. Generally, the inferior mesenteric vein (IMV) drains to the SV. Several variations to this anatomy have been reported, with the most frequent variant being the typical pattern (Type I) just described above, followed by IMV draining into SMV, then SMV joining SV to form PV (Type III), and trifurcation of SMV, IMV, and SV (Type II) respectively.

BACKGROUND: Liver transplantation is currently considered as a definitive therapeutic option for managing patients with chronic liver disease. Due to the considerably greater complexity of LDLT surgical technique, safe harvesting and successful transplantation necessitate cautious donor selection and preoperative mapping of the vascular anatomy. The aim of this study was to evaluate the vascular variations in potential living liver donors and to assess the association between the vascular variance with intra operative and post operative complications.

Methods A technique is described for temporary balloon protection of the vein of Labbé during transarterial Onyx embolization of a type III dural arterio-venous fistula. One illustrative case is presented. Careful anatomic consideration of the concerned venous segment (at the insertion point into the lateral sinus) and the choice of balloon minimized the risk of venous rupture.
