Modified basilic vein transposition surgery for vascular access: Lengthening the basilic vein.
Vascular
December 2024
Department of Vascular Surgery, Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran.
Objectives: Basilic vein transposition (BVT) surgery is a crucial option for vascular access in hemodialysis patients when other alternatives are unavailable. One of the primary complications affecting the long-term function of arteriovenous fistulas (AVFs) is the development of pseudoaneurysms, often caused by repeated punctures at the same site. This study aims to evaluate whether increasing the length of the basilic vein available for cannulation during the second stage of BVT surgery reduces the risk of puncture-related pseudoaneurysms, thereby improving fistula longevity and functionality.

We present a case of biopsy-proven epithelioid angiosarcoma in an arteriovenous fistula (AVF). Angiosarcomas developing in non-functioning AVF in renal transplant recipients are rare clinical entities with poor prognosis. A 59-year-old male adequately immunosuppressed kidney transplant patient presented with pain and swelling at the site of a previously asymptomatic fistula.

Article Synopsis
- The study aimed to evaluate the characteristics of upper limb arteriovenous fistulas used for hemodialysis in patients, focusing on their Doppler ultrasound results.
- Conducted at Yaoundé University Teaching Hospital, it included 41 dialysis patients and found that a significant number had complications such as stenosis and low flow volume.
- Key findings showed that over half of the fistulas were stenosed, with common complications including aneurysms and reverse flow, highlighting a high prevalence of vascular issues in these access points.
Surgical Treatment of Brachiocephalic Artery Aneurysm With Impending Rupture and Tracheal Communication.

Brachiocephalic artery aneurysm is uncommon but may require surgery because it tends to enlarge, rupture, or cause symptoms related to thrombosis or compression. This case report describes a brachiocephalic artery aneurysm in a 72-year-old man who presented at the hospital with dyspnea and hemoptysis resulting from impending rupture and tracheal communication.

Objective: Central vein occlusion (CVO) is a significant complication in patients undergoing chronic hemodialysis, often leading to dialysis inefficacy, disabling symptoms, and, most critically, major risk of access failure. Although stenting has been proposed as a technique to maintain vascular access patency following the recanalization of occluded central veins, the data supporting its long-term efficacy remains limited. This study aims to evaluate the long-term effectiveness of stenting occluded superior vena cava (SVC) and/or brachiocephalic veins to preserve vascular access patency, ensure continued dialysis efficacy, and relieve SVC syndrome.
