Morphological Features of Blood Access Stenosis and Results of Noninvasive Angioplasty

Abstract

We investigated a connection between the results of noninvasive angioplasty for the blood access stenosis and its morphological features in 37 dialysis cases. In 3 cases presenting stenosis in the original artery, the area could not be dilated by noninvasive techniques. In 4 cases with stenosis in the arterialized vein downstream of the needle insertion points for extracorporeal circulation, 3 showed long-term dilatation by the procedures. In 30 cases having stenosis upstream of the points, 16 showed long-term dilatation. In the unsuccessful cases, the angle formed between the axes of the stenosed portion and the normal vessel was over 39 degrees, and the distance between the anastomosis and the stenosed portion was less than 11 mm.

Effect of the combination of percutaneous transluminal angioplasty and pharmacological thrombolysis on hemodialysis patients

“…β2-MG is a small protein that can be detected in a variety of body fluids, such as urine, blood and cerebrospinal fluid. Many investigations have indicated that serum β2-MG level can be used as an indicator of renal function [20,21]. β2-MG has a small molecular weight and is mostly reabsorbed and catabolized by renal tubules.…”
