Comparison between mechanical properties of human saphenous vein and umbilical vein
BACKGROUND As a main cause of mortality in developed countries, Coronary Artery Disease (CAD) is known as silent killer with a considerable cost to be dedicated for its treatment. Coronary Artery Bypass Graft (CABG) is a common remedy for CAD for which different blood vessels are used as a detour. There is a lack of knowledge about mechanical properties of human blood vessels used for CABG, and...
متن کاملHuman Saphenous Vein
We performed experiments to determine whether or not acetylcholine exerts a prejunctional inhibitory effect on adrenergic neurotransmission in the human blood vessel wall. Rings of human greater saphenous veins were prepared 2 to 15 hours after death and mounted for isometric tension recording in organ chambers filled with Krebs-Ringer solution. Acetylcholine depressed contractile responses to ...
متن کاملComparison of therapeutic results of large saphenous vein resection with conventional methods and standard bridging
Background: The use of the traditional method for saphenous vein harvesting is associated with wound complications and not on-time patient mobilization. This has caused the improvement of minimally invasive vein harvesting techniques, together with general bridging. This study was designed to compare the therapeutic results of...
متن کاملSUBTYPES OF α1-ADRENOCEPTORS IN RABBIT SAPHENOUS VEIN
We investigated the a,-adrenoceptor subtypes of rabbit saphenous vein which has a mixed functional population of α1 and α2 -adrenoceptors. Lateral saphenous veins were obtained from male rabbits weighing 3.20-4 kg, which were killed by overdose with pentobarbitone sodium (i.v. injection). They were easily dissected out and placed in cold, oxygenated modified Krebs-Henselite solution (Krebs)...
متن کاملOpening angle of human saphenous vein
In this study, the residual strain was evaluated for human saphenous vein. Rings of the vein from four donors (two male and two female; age 62±5 years) were radially cut to obtain the opening angle (α) of the tissue. It was found that the average opening angle is 45°±18° (mean±SD). Then, the intraluminal distribution of circumferential stress was computed for one donor in order to verify the un...
