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.

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.

Risks and Benefits of Sodium Polystyrene Sulfonate for Hyperkalemia in Patients on Maintenance Hemodialysis.

Background: Concerns about sodium overload when using sodium polystyrene sulfonate (Na-resin) as an ion-exchange resin for the treatment of hyperkalemia led our institution to gradually shift to the use of calcium polystyrene sulfonate (Ca-resin). However, as serum potassium levels were insufficiently controlled and patients experienced constipation, we returned to using Na-resin and observed better results than previously.

Objective: As few papers have examined the potassium adsorption ability of Ca-resin compared with Na-resin, we investigated this issue within our institution.

Long-term outcomes of tonsillectomy for IgA nephropathy patients: A retrospective cohort study, two-centre analysis with the inverse probability therapy weighting method.

Aim: The effect of tonsillectomy on IgA nephropathy remains controversial. The aim of this study was to compare the effect of tonsillectomy on the outcome, end stage kidney disease (ESKD) and all-cause death in IgA nephropathy patients who did and did not undergo tonsillectomy.

Methods: All basic data were retrospectively gathered from patients who had undergone renal biopsies at two Japanese clinical centres.

Successful treatment of a patient with refractory nephrotic syndrome with PCSK9 inhibitors: a case report.

Background: The proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor evolocumab is a low-density lipoprotein (LDL)-lowering drug with a new mechanism, which is currently available in Japan. Here, for the first time, we report the successful use of the PCSK9 inhibitor in a patient with refractory nephrotic syndrome.

Case Presentation: A 61-year-old woman was diagnosed with minimal change-type nephrotic syndrome in October 2012.

A report of an adult case of tubulointerstitial nephritis and uveitis (TINU) syndrome, with a review of 102 Japanese cases.

Background: Although TINU syndrome is characterized by idiopathic TIN with bilateral anterior uveitis, few reports have provided a comprehensive summary of the features of this disorder. Previous reports have suggested that many Japanese patients had HLA-A2 and -A24 (7), but there is no evidence.

Case Report: A 44-year-old female was referred to our hospital due to renal dysfunction in March 2012.

A comparison of the long-term effects of lanthanum carbonate and calcium carbonate on the course of chronic renal failure in rats with adriamycin-induced nephropathy.

Lanthanum carbonate (LA) is an effective phosphate binder. Previous study showed the phosphate-binding potency of LA was twice that of calcium carbonate (CA). No study in which LA and CA were given at an equivalent phosphate-binding potency to rats or humans with chronic renal failure for a long period has been reported to date.
