OBJECTIVE Spinal dural arteriovenous fistulas (dAVFs) are rare vascular abnormalities caused by arteriovenous shunting. They often form at the dural root sleeve between a radicular feeding artery and draining medullary vein causing venous congestion and edema, decreased perfusion, and ischemia of the spinal cord. Treatment consists of either surgical ligation of the draining vein or selective embolization via an endovascular approach. There is a paucity of data on which modality provides more durable and effective outcomes...

The number and complexity of endovascular procedures performed via either arterial or venous access are steadily increasing. Albeit associated with higher morbidity compared to the radial approach, the traditional common femoral artery remains the preferred access site in a variety of cardiac, aortic, oncologic and peripheral vascular procedures. Both transarterial and venous cannulation (for electrophysiology, intravenous laser ablation and central catheterisation) at the groin may result in potentially severe vascular access site complications (VASC)...

Intracranial endovascular interventions provide effective and minimally invasive treatment of a broad spectrum of diseases. This area of expertise has continued to gain both wider application and greater depth as new and better techniques are developed and as landmark clinical studies are performed to guide their use. Some of the greatest advances since the last American Heart Association scientific statement on this topic have been made in the treatment of ischemic stroke from large intracranial vessel occlusion, with more effective devices and large randomized clinical trials showing striking therapeutic benefit...

BACKGROUND: The definition of significant stenosis (SS) remains controversial. METHODS: We retrospectively reviewed 1,040 consultations. SS was defined in the presence of clinical and echo-Doppler (DDU) criteria: Qa <500 mL/min or Qa decrease >25%; RI >0.7 in the feeding artery or absolute minimal luminal stenosis diameter <2.0 mm. Stenosis without any additional criteria were considered borderline stenosis (BS). RESULTS: Two hundred twenty-one arteriovenous fistulas (AVFs) were included: 58...

Background: For hemodialysis patients with end-stage renal disease (ESRD), it is important to construct an efficient vascular access with a superior patency rate. This study investigated the factors influencing the efficiency of arteriovenous fistulas (AVFs) constructed using an autologous vessel and evaluated the necessity of ultrasonography as a preoperative tool for AVF construction. Methods: A retrospective analysis was performed of 250 patients in whom an AVF was constructed using an autologous vessel due to ESRD at our institution from January 2009 to April 2016...

The aim of this study was to evaluate in the Wistar rat the efficacy of various autologous nerve conduits with various forms of blood supply in reconstructing a 10-mm-long gap in the median nerve (MN) under conditions of local ischemia. A 10-mm-long median nerve defect was created in the right arm. A loose silicone tube was placed around the nerve gap zone, in order to simulate a local ischemic environment. Rats were divided in the following experimental groups (each with 20 rats): the nerve Graft (NG) group, in which the excised MN segment was reattached; the conventional nerve flap (CNF) and the arterialized neurovenous flap (ANVF) groups in which the gap was bridged with homonymous median nerve flaps; the prefabricated nerve flap (PNF) group in which the gap was reconstructed with a fabricated flap created by leaving an arteriovenous fistula in contact with the sciatic nerve for 5 weeks; and the two control groups, Sham and Excision groups...

Vein of Galen aneurysmal malformation (VGAM) is a rare angiopathy, which most commonly presents in infancy. Although very rare, it is associated with high morbidity and mortality rates. In order to minimize such morbid rates, a prompt diagnosis followed by a timely initiation of management is crucial. Multiple antenatal and postnatal imaging techniques for the diagnosis have been described and discussed in the literature. However, to our knowledge, a comprehensive review exploring such a list of imaging options for VGAM has never been established...

In Pakistan, patients with chronic kidney disease (CKD) are commonly diagnosed at a late stage. There is little information about the refusal of hemodialysis by hospitalized CKD patients who need hemodialysis (HD) and reasons for acceptance and refusal among these patients. All patients with Stage V CKD who had medical indications to undergo HD and were hospitalized at a tertiary care facility over a six-month period were invited to participate in this study. Patients were surveyed regarding acceptance or refusing of HD and reasons for their decisions...

The fistula first initiative has rekindled interest in transposition of basilic vein (TBV) in preference to arteriovenous grafts (AVG). TBV is considered to have advantages over AVG. The aim of this study was to analyze the outcome of TBVs in our center comparing them to a historically matched group of patients who had AVG. Thirty-two patients who underwent TBV as a vascular access procedure in Derriford Hospital between January 2010 and October 2014 were included in the study. The historical control group comprised 31 patients who had AVG inserted in the upper arm between January 1999 and December 2010...

INTRODUCTION: There is increasing acknowledgement that surgical care is important in global health initiatives. In particular, neurosurgical care is as limited as 1-to-10 million people in parts of the world. We performed a systematic literature review to examine the worldwide incidence of central nervous system vascular lesions (CNS-VL) and a meta-analysis of aneurysmal subarachnoid hemorrhage (ASAH) in order to define the disease burden and inform neurosurgical global health efforts...

INTRODUCTION: Stenosis of an arteriovenous fistula or arteriovenous graft for dialysis is a common problem. Stenosis may lead to a number of problems including failure of the fistula. Treatment of stenosis is commonly with percutaneous angioplasty or surgical patch angioplasty with autologous vein or synthetic graft or patch. Here we report the use of bovine pericardial patch angioplasty as an alternative mode of patch angioplasty when percutaneous intervention has failed. METHODS: Patients with fistulae treated with bovine patch angioplasty between 2013 and 2016 were identified from a prospectively maintained renal access database (Cyberren® )...

Diabetic nephropathy is the most frequent cause of end-stage renal disease worldwide. Dialysis patients with diabetes mellitus (DM) have more complications and shorter survival duration than non-DM dialysis patients, requiring more clinical attention and difficult management. The registry committee of the Korean Society of Nephrology has collected data about dialysis therapy in Korea through an on-line registry program and analyzed the characteristics of patients. A survey of dialysis patients in 2016 showed that 50...

The maintenance of vascular access patency for end-stage renal disease patients on hemodialysis is necessary for survival. Many nephrologists, nurse practitioners, and nurses have limited experience with the physical examination of the arteriovenous fistula. In this review, we define key terms used in the assessment of an arteriovenous fistula. We discuss the arteriovenous fistula physical exam, including details of inspection, palpation, and auscultation. Using these concepts, we review the abnormal findings that can assist practitioners in determining the location of a stenosis...
