in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

BACKGROUND Hemodialysis used as renal replacement therapy requires a well-functioning vascular access. Arterio-venous fistula (AVF) created on the forearm is the best vascular access, but it also reveals numerous complications such as: lack of fistula maturation and hemodynamically significant stenoses. Many risk factors of fistula dysfunction are still not identified. MATERIAL/METHODS Radial...

BACKGROUND An autogenous arteriovenous fistula is the optimal vascular access for hemodialysis. In the case of brachiocephalic fistula, cephalic arch stenosis commonly develops leading to access failure. We have hypothesized that a contribution to fistula failure is low wall shear stress resulting from post-fistula creation hemodynamic changes that occur in the cephalic arch. METHODS Twenty-t...

Autogenous arteriovenous fistula (AVF) is the first choice for hemodialysis access in renal failure with uremia. However, AVF cannot be performed in some patients due to small and narrow veins in the forearm. In this study, a Fogarty catheter was used to establish autogenous radiocephalic hemodialysis access in patients with small caliber cephalic veins, and the patency rate and complications o...

Introduction The incidence of renal failure is gradually increasing in India. These patients need renal replacement therapy. Renal replacement therapy is provided in the form of dialysis and renal transplant. As the survival after renal failure is increasing because of the availability of renal replacement therapy, there is increased demand for angio access. For temporary angio access central d...

BACKGROUND The analysis of hemodialysis services is relevant for the quality of life of patient. In this study we investigated the profile of vascular access used for hemodialysis patients in our Unit. METHODS We evaluated 219 patients of both genders aged over 18 years old who have undergone implant or manufacture of vascular hemodialysis access. We excluded patients on renal replacement the...

INTRODUCTION The autogenous brachiocephalic fistula is a recognized secondary access for hemodialysis. However, veins in the antecubital fossa are often damaged, due to repeated venipunctures and subsequent scarring. Sometimes their anatomy does not enable successful arteriovenous fistula creation. In cases when the proximal part of the cephalic vein seemed patent, during ultrasound Doppler exa...

Abstract Background Pseudoaneurysm formation is known to complicate arteriovenous haemodialysis access. Ultrasound guided thrombin injection a recognised treatment option, but not possible in pseudoaneurysms with no measurable neck. Balloon assisted techniques have been described such cases, which transiently obstruct flow out of the pseudoaneurysm and thereby prevent non-target embolization du...
