Renal arteriovenous fistula (AVF) is an uncommon anomaly characterized by the communication between renal arteries and veins. Renal AVFs are often asymptomatic but are occasionally accompanied by hematuria or heart failure. Transcatheter closure with embolization is a safe and effective treatment for renal AVF. We herein report an 87-year-old patient with heart failure due to renal AVF who was ...

Background and Objectives: Arteriovenous fistula is a popular vascular access method for surgical treatment of 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, ...

As both congenital (AVM) and acquired arteriovenous malformations (fistulas) may cause congestive heart failure and aneurysm formation, they should be repaired. The surgicai management of a traumatic arteriovenous fistula (AVF) is the surgical division of the fistula and primary repair of the involved artery and vem’ or the ligation of the main feeding and draining vessels.2 The anatomic locati...

Tc-99m-DTPA renal scintigraphy was performed before and after transcatheter coil embolization in a patient with renal arteriovenous fistula (AVF). Before embolization, scintigraphy showed a characteristic accumulation pattern compatible with the hemodynamics of an aneurysmal type of AVF in the vascular phase. After embolization, the effects of treatment, such as a change in the split renal func...

  Background: Arteriovenous Fistula (AVF)is the ideal method of vascular access for patients on maintenance hemodialysis (HD).Therefore it is an important part of treatment in HD.There are several observations that indicate the role of inflammation in failure of AVF.The aim of this study was to evaluate the hematologic and inflammatory biomarkers in early AVF failure.   Methods : This case-cont...

Local complications of arterial puncture include hematoma, pseudoaneurysm and formation of arteriovenous fistula (AVF). The latter could cause ischemia of the particular extremity or can be hemodynamically significant especially in patients suffering from congestive heart failure. We report a case of femoro-femoral AVF after thin needle arterial p...

A 68-year-old male presented an unusual dural arteriovenous fistula (AVF) located at the craniocervical junction. Magnetic resonance imaging revealed dilated perimedullary veins around the spinal cord at C-1 and C-2 levels, as well as high intensity signals in the spinal cord on T2-weighted images. Vertebral angiography identified an AVF at the point where the right vertebral artery penetrates ...

It remains challenging to accurately predict whether an individual arteriovenous fistula (AVF) will mature and be useable for haemodialysis vascular access. Current best practice involves the use of routine clinical assessment and ultrasonography complemented by selective venography and magnetic resonance imaging. The purpose of this literature review is to describe current practices in relatio...

We report a case of a posterior fossa arteriovenous fistula (AVF) with bithalamic hyperintensity of MR images. The thalamic abnormality improved after surgery, suggesting reversible venous hypertension as the pathogenesis of the finding, as opposed to infarction. This manifestation of a posterior fossa AVF should be considered in the differential diagnosis of bilateral thalamic disease.

A patient presented with cardiac failure and investigations revealed a right femoral arteriovenous fistula (AVF) 5 weeks after the insertion of a femoral dialysis catheter for haemodialysis. No ultrasound had been used for catheter insertion. The iatrogenic AVF was repaired, and her episodes of cardiac failure ceased. It is recommended that femoral dialysis catheters are inserted using ultrasou...
