Type II Cryoglobulinemic Membranoproliferative Glomerulonephritis Caused by Mucosa-associated Lymphoid Tissue Lymphoma.

A 67-year-old man complained of lower limb edema with a purpuric skin rash. Laboratory tests revealed proteinuria, elevated serum creatinine levels, and low serum albumin levels. The patient was also positive for cryoglobulin in serum, immunoglobulin (Ig) M gammopathy, hypocomplementemia, and rheumatoid factor.

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.

Restoration of Autologous Arteriovenous Fistula by Removal of the Occluded Short Venous Part and Venovenous End-To-End Anastomosis in a Hemodialysis Patient.

Standard salvage procedures for occuluded autologous arteriovenous fistula (AVF) in a hemodialysis patient are endovascular and/or surgical therapy. When endovascular therapy and thrombectomy prove unsuccessful, it is most likely that creating a new AVF or arteriovenous graft will be considered. However, if the occuluded venous part is short, we have adopted an operative technique for repair of AVF by removal of the occluded short venous part and venovenous end-to-end anastomosis.
