INTRODUCTION An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein which may result from traumatic injury or may occur as congenital abnormality. Stent graft repair through arteriovenous fistula could lead to complications. CASE REPORT Endovascular stent graft repair in a 23-year-old patient with posttraumatic superficial femoral arteriovenous fistula was perfo...

Laminar shear stress (SS) induces an antiproliferative and anti-inflammatory endothelial phenotype and increases Klf2 expression. We altered the diameter of an arteriovenous fistula (AVF) in the mouse model to determine whether increased fistula diameter produces disturbed SS in vivo and if acutely increased disturbed SS results in decreased Klf2 expression. The mouse aortocaval fistula model w...

This is a case of 62-year-old patient presenting with tingling and numbness extending from the buttocks area towards lower extremities gait instability. Contrast Magnetic Resonance Imaging (MRI) time-resolved imaging contrast kinetics (TRICKS MRI) raised suspicion for possible dural arteriovenous fistula. Diagnostic Digital Subtraction Angiography (DSA) showed filum terminale arterio venous fis...

The major problem associated with the creation of an arteriovenous fistula (AVF), which is the optimal form of vascular access for hemodialysis, is the fact that fistulas do not necessarily mature into a usable vascular access, requiring subsequent revision and construction of another access. The caliber of the vessels used for fistula creation is a pivotal factor predicting the presumable matu...

A 66-year-old woman was found unresponsive after complaining of severe headache several days prior. She was comatose upon initial evaluation and a cranial CT revealed diffuse subarachnoid hemorrhage. A right posterior communicating artery aneurysm (figure, A, arrow) was successfully treated with endovascular embolization. Conventional angiography performed 7 days following ventriculostomy place...

Vascular access stenosis is a major complication in hemodialysis patients. We prospectively observed 50 patients in whom 50 nitinol shape-memory alloy-recoverable technology (SMART) stents were used as salvage therapy for recurrent peripheral venous stenosis. Twenty-five stents each were deployed in native arteriovenous fistula (AVF) and synthetic arteriovenous polyurethane graft (AVG) cases. V...

PURPOSE We describe a patient presenting with a vascular mass of the lower lip with a history of traumatic lip-biting. The lesion was treated with preoperative intravascular embolic therapy and surgical excision. SUMMARY Arteriovenous fistula (AVF) of the head and neck are vascular lesions with a single connection between the involved artery and vein. Trauma to the area, often in the distant ...

Dialysis Access is the “lifeline” for 1.5 million end-stage renal disease (ESRD) patients across the world. Effective hemodialysis treatment requires reliable large caliber vascular access. The preferred hemodialysis access is an arteriovenous fistula (AVF) because of its lower infection rate, lower hospitalization rate and relatively longer longevity compared to grafts.(1, 2) However, the prim...

background and objectives: arteriovenous fistula is a popular vascular access method for surgical treatmentof hemodialysis patients. the method, however, is associated with a high rate of early failure varying in the range of 20-60%. predicting early arteriovenous fistula failure and its risk factors can help reduce its incidence, its hospitalization rate, and associated costs. in this study, w...

A single-hole arteriovenous fistula (A VF) consists of a solitary abnormal communication between an artery and a vein without an intervening capillary network. An AVF must be distinguished from an arteriovenous malformation (A VM), which is composed of a complex network of arteriovenous connections (nidus or core). Most AVFs develop as a result of trauma; those between the internal carotid arte...
