Observation and nursing care of carotid artery stenosis patients with postoperative complications after accepting intravascular stent implantation

Objectives: To explore the safety and efficacy of carotid angioplasty and stenting (CAS) with cerebral protection devices for carotid stenosis.

Biocompatibility and biological safety of the external stent material polydioxanone in vitro & in vivo study;

At present, the external stent is one of the most advanced medial appliances in the world.

Experimental study of external stents preventing stenosis of porcine saphenous vein grafts′ anastomosis;

Objective To evaluate the effect of external stents on preventing vein graft neointima formation and medial thickening with non-restrictive marcroporous polyester stent around vein grafts in pigs.

Knitting of the warp knitted external vascular stent and its properties study and its properties study

Lots of research has indicated that the external vascular stent can relieve the intimal hyperplasia of vein from grafting,avoid atherosclerosis,and improve the patency rate.
