On the Mechanical Failure of Arterial Prostheses
Nowadays, the use of synthetic grafts to bypass occluded arterial sections is common practice in clinics and hospitals. Success has been achieved in cases involving large diameter blood vessels. However, for arteries with a diameter less than 5 mm, the success rates for synthetic grafts have been low mainly due to intimal hyperplasia formation at anastomoses. The postulated reasons affecting gr...
متن کاملArterial Smooth Muscle Cells
Heparin is a potent inhibitor of arterial smooth muscle cell (SMC) migration and proliferation in vivo and in vitro. We propose that heparin affects these SMC functions by interfering with either the expression or the activity of secreted proteases required for cell movement. We have reported that heparin selectively inhibits the expression of tissue-type plasminogen activator in SMCs during mi...
متن کاملArterial smooth muscle.
T he prime function of the arterial smooth muscle cell (SMC) in adult individuals is to contract and relax, thereby regulating blood flow to target tissues. However, in several vascular diseases, arterial SMCs in the adult vessel undergo major changes in structure and function. For example, SMCs can take on properties that allow them to proliferate and migrate, to promote calcification, to unde...

Background and Purpose: Previous studies have suggested that bilirubin is a potential contributor to cerebral vasospasm. The purpose of this investigation was to determine whether bilirubin accrues in subarachnoid clot, whether its vasoconstrictive effect could involve a direct action on arterial smooth muscle cells, and, if so, whether bilirubin affects their Ca2+ uptake. Methods: Subarachnoid...
متن کاملExperimental evaluation of ten clinically used arterial prostheses.
The arterial grafts currently in use are classified into five basic categories; 10 different commercially available prostheses were chosen to represent these categories. The Vascutek and Bionit are made from knitted Dacron and have medium porosity, requiring preclotting by the surgeon. The DeBakey Soft Woven and Plasma TFE grafts are made from woven Dacron and have low porosity, not requiring p...
