Cellular phenotypes in human stenotic lesions from haemodialysis vascular access.
BACKGROUND Haemodialysis vascular access dysfunction (due to venous stenosis and thrombosis) is a leading cause of hospitalization and morbidity. The aim of the current study was to identify the specific cell types present within stenotic tissue samples from patients with AV fistula and graft failure. METHODS Discarded tissue segments were collected from the stenotic portions (usually near th...
متن کاملStenotic lesions in vascular access: treatment with transluminal angioplasty using high-pressure balloons.
In our institute, one hundred sixty-four balloon dilatations of stenotic lesions in vascular access have been performed since November 1991. All of these procedures were done with high-pressure balloon catheters. In addition to seventy-four cases treated with only percutaneous transluminal angioplasty, there were thirty-four cases which were treated by thrombectomy and/or surgical revision with...
متن کاملPhysical factors in the progression of stenotic vascular lesions.
An explanation of the progression of stenotic lesions was sought in animal experiments. After surgical decrease of the lumen of arteries, progressive ingrowth of fibrous connective tissue led to the development of stenosis with changes in the artery that resembled those of coaretation. These changes are explained by the action of local blood pressures. Phenomena such as progressive stenosis, va...
متن کاملVascular access: the impact of ultrasonography
Vascular punctures are often necessary in critically ill patients. They are secure, but not free of complications. Ultrasonography enhances safety of the procedure by decreasing puncture attempts, complications and costs. This study reviews important publications and the puncture technique using ultrasound, bringing part of the experience of the intensive care unit of the Hospital Israelita Alb...
