Abstract

We have been using porous Dacron prostheses according to Wesolowski's gossamer concept. Woven Dacron prostheses with porosity below 300ml/cm²/min at 120mmHg have been chosen for the thoracic aortic surgery and high porous weft-knit Dacron prostheses with porosity between 2000 and 3000ml for the abdominal aortic and the distal arterial surgery. Our choice of vascular prostheses has been influenced by recent experimental and clinical results. An albumin-autoclave method and fibrin-glue preclotting are used to make the conventional woven and knitted Dacron grafts impervious. External velour warp-knit Dacron prostheses are gradually used for the abdominal aortic and the iliac arterial surgery. Externally supported Dacron prostheses are going to be used for the femoropopliteal area.
