Abstract
For surgical reconstruction of thoracic and abdominal aorta and peripheral artery, we use a straight and Y shaped Toray graft® which was made of an ultrafine polyester fiber (UFPF). Toray grafts® were implanted for 52 cases. This prosthesis has woven structure and has properties of healing and pliability, In addition its porosity is 100ml/min/cm2, . Entangled UFPF prevented blood leakage and accelerated its healing. In clinical use for thoracic aorta we treated this proshtesis with heated, denatured albumin. For abdominal aorta this prosthesis was preclotted for about 2 min, after proximal aorta was anastomosed For peripheral arteries any pre- or post- treatments for this prosthesis was not performed. Its fittness and handling in suture to the aorta were distinguished compared to another woven Dacron graft.
