This study is to investigate hematuria in pregnant patients caused by renal arteriovenous malformation and to evaluate the efficacy of superselective renal angiography and embolization used for treatment of renal arteriovenous malformation. Two cases of hematuria in pregnant patients caused by renal arteriovenous malformation were enrolled. Case 1 was a 28-year-old woman with repeatedly intermi...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to loo...

dural arteriovenous fi stula (davf) is also known as dural arteriovenous malformation. two forms of davf have been introduced, however, here we present an exceptional case of davf with unique origin and drainage. in this study, we present a rare case of multiple davfs in a 50 year old man with right parietal intraparenchymal hemorrhage. mri showed two round right parieto-occipital masses with f...

BACKGROUND AND PURPOSE Spinal dural arteriovenous fistulas are commonly missed on imaging or misdiagnosed as inflammatory or neoplastic processes. We reviewed a consecutive series of spinal dural arteriovenous fistulas referred to our institution that were missed or misdiagnosed on initial imaging and studied the clinical consequences of missing or misdiagnosing the lesion. MATERIALS AND METH...

Intimal hyperplasia is one of the prominent failure mechanisms for arteriovenous fistulas and arteriovenous access grafts. Human tissue-engineered vascular grafts (TEVGs) were implanted as arteriovenous grafts in a novel baboon model. Ultrasound was used to monitor flow rates and vascular diameters throughout the study. Intimal hyperplasia in the outflow vein of TEVGs was assessed at the anasto...

Arteriovenous fistulas of the thoracic wall may produce murmurs and thrills which suggest an intrathoracic vascular abnormality. Congenital arteriovenous fistulas in the plecordial region, the site of the fistula in the case here reported, may be confused with anomalies of the heart and great vessels. The differential diagnosis of blood vessel tumors of the chest wall is discussed. Occasionally...

Arteriovenous malformations of the lung are rare pulmonary vascular disorders which can suddenly lead to life threatening complications. Haemothorax due to rupture of a pulmonary arteriovenous malformation (PAVM) is very rare. We report here a case of a 39 year-old lady who presented with an acute onset of shortness of breath due to right-sided massive haemothorax and was subsequently detected ...

Dural arteriovenous fistula of the cavernous sinus is usually a benign disease and rarely has brainstem edema as its complication. We present a patient with dural arteriovenous fistula of the cavernous sinus and brainstem edema. The brainstem edema resolved after embolization. Embolization should be considered first whenever brainstem edema occurs, progressive visual deterioration or increased ...

Background: Hemodialysis patients experience pains induced by cannulation of an arteriovenous (AV) fistula. The effect of mirror therapy on patients’ pain severity has not been investigated in individuals living with hemodialysis. Aim: The purpose of the present study was to investigate the effect of mirror therapy on AV fistula cannulation-related pain s...

OBJECTIVE To evaluate the two year patency rate of functioning arteriovenous fistula. METHODOLOGY This prospective case series study was conducted at Department of Urology, Jinnah Postgraduate Medical Centre, Karachi, from 1(st) January 2009 to 31(st) December, 2010. Patients were chosen for CBRC arteriovenous fistula at wrist and patients undergoing other types of vascular access or secondar...
