We aimed to analyze patency and risk factors after inflow arterial PTA. Hemodialysis patients with inflow arterial primary stenosis who were admitted to our institution from January 2017 to December 2022 were examined.

Long-Term Efficacy of Ultrasound-Guided Percutaneous Transluminal Angioplasty for Arteriovenous Fistula Outflow Stenosis Caused by Venous Valve.

Introduction: Venous valve-related stenosis (VVRS) is an uncommon type of failure of arteriovenous fistula among patients with end-stage renal disease (ESRD). There is a paucity of data on the long-term efficacy of ultrasound-guided percutaneous transluminal angioplasty (PTA) for VVRS.

Methods: ESRD patients who underwent PTA because of VVRS between January 2017 and December 2021 at the First Affiliated Hospital of Chongqing Medical University were enrolled.

Acute upper limb ischemia caused by thrombus shedding during arteriovenous graft thrombolysis: A case report.

Acute upper limb ischemia is a rare, potentially limb- or life-threatening vascular emergency that may lead to limb dysfunction or amputation. We present a patient undergoing maintenance hemodialysis who was hospitalized for arteriovenous graft thrombus complicated by acute upper limb ischemia arising from thrombus shedding to the fingertip arteries during thrombolysis. We successfully restored fingertip arterial patency, avoided amputation, and recovered the function of the arteriovenous graft by precise thrombolysis, anticoagulation, correction of arteriospasm, and percutaneous transluminal angioplasty.

Migration of covered stents in thoracic central vein obstruction procedures in patients with hemodialysis: Case report and literature review.

Objective: The objective of the study is to present a case of hemodialysis in which the covered stent that had migrated into the right ventricle was retrieved by exploratory thoracotomy, and to review the literature on the diagnosis and treatment of stent migration in thoracic central vein obstruction (TCVO) procedures for hemodialysis patients.

Delamination and dissection of arteriovenous grafts: A multicenter report of four cases.

Arteriovenous (AV) grafts are an alternative vascular access for chronic hemodialysis. AV graft failure is often due to stenosis of the feeding artery, graft, or draining vein. We report four cases of AV graft dysfunction and failure rarely caused by graft delamination and dissection.
