Arteriovenous fistula (AVF) dysfunction is one of the common obstacles in performing hemodialysis treatment. Acute and chronic thrombosis fistula, stenosis, hematomas are major causes dysfunction. Here, we present an unexpected complication midodrine use which caused AVF a female patient who was suffering from hemodialysis-related hypotension.

PURPOSE To examine the clinical and radiographic findings in a large group of patients having or suspected of having a spinal dural arteriovenous fistula. METHODS An analysis of 240 spinal angiograms in 132 patients revealed 97 vascular malformations that included 66 spinal dural arteriovenous fistulas. Sixteen patients had 1 or more normal spinal angiograms that were performed for suspected ...

OBJECTIVE: The objective of this selective evidence based medicine review is to determine whether or not far infrared therapy reduces the incidence of arteriovenous fistula (AVF) malfunction in patients with renal disease undergoing hemodialysis. STUDY DESIGN: Review of three primary randomized controlled trial studies published from 2007-2013. DATA SOURCES: Three peer-reviewed randomized contr...

Femoral arteriovenous fistula is a rare complication of percutaneous transfemoral catheterization. We report the duplex Doppler findings of three such cases. Continuous positive diastolic arterial flow, as well as an abnormal venous flow pattern, was observed in all cases. When present, these Doppler spectral changes support the diagnosis of arteriovenous fistula.

The MR findings in three patients with intracranial dural arteriovenous fistula associated with cervical myelopathy are described. The MR appearance of an enlarged cord with associated abnormal signal and enhancement is nonspecific and can simulate tumor, demyelination, and inflammation. Enlarged perimedullary vessels may not always be identifiable, but if present, should suggest the presence o...

BACKGROUND We report a unique case of an acquired pial arteriovenous fistula occurring after an asymptomatic thrombosis of a superficial cerebral vein. CASE DESCRIPTION A cerebral angiogram performed in a 51-year-old man with subarachnoid hemorrhage revealed a 10-mm ruptured anterior communicating artery aneurysm and a thrombosed left superficial middle cerebral vein. Coil embolization of the...

Iatrogenic arteriovenous fistula (AVF) is usually caused by inappropriate blood vessel cannulation during diagnostic and interventional procedures [1–3]. Arteriovenous fistulas occur in 1.0–1.5% of cases following procedures with femoral access (FA) [1, 4, 5]. Iatrogenic fistulas are unintentional connections between an artery and a vein due to the needle being advanced too deeply and reaching ...

Coronary arteriovenous fistulas are rare and are usually diagnosed in children or young adults. Most are believed to be congenital. A right coronary arteriovenous fistula was first diagnosed in a patient of 74. Despite her age the fistula was successfully operated on and her symptoms were relieved.

Subclavian steal syndrome (SSS) has been well described in the setting of subclavian stenosis. We describe an unusual case of SSS caused by a high-flow arteriovenous dialysis fistula in the absence of subclavian stenosis, provide a review of the literature, and propose that arteriovenous fistula-induced SSS is an underdiagnosed cause of syncope in this population of patients.

Arteriovenous fistulas of the extracranial vertebral artery are rare. The authors report a case of a spontaneous arteriovenous fistula of the extracranial vertebral artery presenting as an osteolytic lesion at the body of the axis. The patient presented with headache and posterior neck pain. The fistula was obliterated by an endovascular trapping.
