Abstract
A clinical study of a newly developed prosthesis coating with gelatin was carried out to evaluate its efficiency as a zero-porosity prosthesis. From January 1995 to October 1996 those prostheses were used in 79 patients, of which 20 were for the thoracic aorta, 53 were for the abdominal aorta, and 6 were for the iliac artery. Clinical studies were completed in 66 patients. Therein such factors as suturability, hemorrhage, hemostat and flexibility, and the 6 month patencies of prostheses were evaluated. Changes in the blood cell count, chemistry, and body temperature were also studied. The results indicated that the surgical suitability was excellent and patencies of all prostheses were good except for one iliac artery occlusion. Though the body temperature of all patients was elevated after surgery along with the WBC counts and C-reactive protein values, these elavated values represent an ordinary inflammatory response after surgery. It can therefore be concluded that the new prosthesis has many clinical advantages and shows good performance as an artificial graft.
