Brachio-brachial arteriovenous fistula combined with superficialization of the brachial artery using a short skin incision for hemodialysis.

A brachio-brachial arteriovenous fistula with superficialization of the brachial vein and superficialization of the brachial artery are useful vascular access techniques for hemodialysis patients. However, both typically require a long skin incision from the antecubital fossa toward the axillary fossa. In addition, the brachio-brachial arteriovenous fistula in particular, which is created with not a one-stage but a two-stage procedure, requires a relatively long time of 2-3 months before it can be used for hemodialysis.

Radial artery-second dorsal metacarpal vein arteriovenous fistula in the first interdigital space for hemodialysis: Utilization of the most peripheral site and autologous vein in the upper limb - A case report.

Introduction: The creation of the first arteriovenous fistula (AVF) as far distally in the upper limb as possible is ideal. We developed a new operative technique for creating a radial artery-second dorsal metacarpal vein AVF in the first interdigital space. This technique involves the creation of the AVF using the most peripheral site and autologous vein in the upper limb.

Radial artery-first dorsal metacarpal vein arteriovenous fistula in the first interdigital space of the dorsal hand for hemodialysis.

A radiocephalic arteriovenous fistula in the anatomical snuffbox (tabatière region) was first described in 1969 as the most peripheral site for arteriovenous fistula in the upper limb. In cases in which the internal diameter of the first dorsal metacarpal vein under avascularization is ⩾2.0 mm, we have adopted a new operative technique for creating a radial artery-first dorsal metacarpal vein arteriovenous fistula in the first interdigital space of the dorsal hand, which lies between the thumb and the index finger.

Use of the Dorsal Vein of the Hand for Arteriovenous Fistula Creation.

A radiocephalic arteriovenous fistula (AVF) in the anatomical snuffbox is the most distal site of AVF in the upper limb. When the cephalic vein distal to the wrist is in poor condition or thrombosed, creating the typical radiocephalic AVF in the distal forearm just proximal to the wrist will likely be considered. However, we have adopted an operative technique for creating a transposed radial artery-dorsal metacarpal vein AVF (RDAVF) in the anatomical snuffbox when possible in such cases.

Hemodialysis treatment time versus erythropoietin dose requirement: Reduction in 2,000 units per week by extension of hemodialysis for 1 hour .

Introduction: High-dose erythropoietin (EPO) administration to hemodialysis (HD) patients with EPO hyporesponsiveness, due to iron deficiency, hyperparathyroidism, malnutrition, inflammation, and inadequate HD, results in increased risk of mortality and cardiovascular events. We investigated the relationship of the EPO dose requirement with 4-, 5-, and 6-hour HD treatment times.

Materials And Methods: This cross-sectional study enrolled 300 HD patients, including those on 4-hour HD (n = 78), 5-hour HD (n = 106), and 6-hour HD (n = 116).

A one-sheath inverse method in vascular access intervention therapy for hemodialysis patients.

Introduction: Vascular access intervention therapy (VAIVT) is an essential interventional therapy in the field of hemodialysis therapy that allows for the long-term vascular access functionality to be maintained. The venous approach is often performed in VAIVT for arteriovenous fistula. When lesions are present on the upstream and downstream sides from the approach site, it is likely that two sheaths will be inserted from two facing punctures.
