Arteriovenous (AV) fistulas are common in renal cell carcinoma. These are usually small and asymptomatic. Case reports have previously described symptomatic fistulas in primary renal cell tumour or, less commonly, bone metastases. The current study describes a patient with lung metastases from renal cell carcinoma who developed a symptomatic pulmonary AV fistula. The patient presented with debi...

Aim. The objective of this study was to characterize coordinated molecular changes in the structure and composition of the walls of venous segments of arteriovenous (AV) fistulas evoked by overflow. Methods. Venous tissue samples were collected from 6 hemodialysis patients with AV fistulas exposed to overflow and from the normal cephalic veins of 4 other hemodialysis patients. Total RNA was ext...

INTRODUCTION AND PURPOSE The increasing number of patients undergoing hemodialysis and the limited number of access sites have resulted in an increasing number of techniques to maintain vascular access for hemodialysis. Thrombosed arteriovenous (AV) fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definit...

BACKGROUND This study was undertaken to expand the understanding of ultrasound-guided compression repair (UGCR) of postcatheterization femoral artery injuries. METHODS AND RESULTS In a series of 62 patients with pseudoaneurysms (n = 53) or arteriovenous (AV) fistulas (n = 9), UGCR was performed as a nonsurgical method in the treatment of postcatheterization femoral artery injuries. When the c...

A coronary arteriovenous (AV) fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common anomaly that can affect coronary perfusion. Yet bilateral involvement of a coronary fistula, constitutes an uncommon subgroup of coronary AV fistulas. We herein report on a case of bilateral coronary AV fistula that was coexist...

Intravenous drug abusers commonly develop endocarditis due to injection of particulate matter that can cause endothelial damage to the valves. The frequent need to access the venous system can result in vascular traumas with potential complications including arteriovenous (AV) fistulas. Here, we present the case of an intravenous drug abuser with endocarditis and an unusually large AV fistula i...

Traumatic arteriovenous fistulas of the neck are treated by endovascular method or open surgery according to clinical presentation patient and degree emergency. This case report concerns two delayed onset fistulas, one between right common carotid artery internal jugular vein, other facial caused a previous penetrating trauma. Initially, AV fistula was intervention using multiple vascular plugs...

BACKGROUND Wound morbidity commonly accompanies transposition of the femoral vein when used for hemodialysis access, mainly because of the length of the skin incision. A short incision may reduce wound complications but may compromise the arteriovenous (AV) function because of the shorter length of femoral vein available for puncture. This report presents our experience with a modification of t...

AIM The aim of the study is to make a retrospective analysis of the incidence of AV fistulas after renal biopsy (RB) of native and transplanted kidney. MATERIALS AND METHODS Five hundred and sixteen (516) RB were analyzed. One hundred twenty nine (129) were native kidneys RB performed in Clinic of Nephrology (CN), 190 were performed in Clinic of Nephrology and transplantation (CNT) and 197 we...
