Clinical experience in 1040 patients with double-velour knitted Dacron vascular prostheses: With particular reference to dilatation and aneurysm formation.

Recent reports of dilatation and aneurysm formation in Dacron fabric grafts have prompted us to review our experience with 1040 patients who received Meadox-Cooley double-velour knitted grafts over a 47-month period. Bifurcation grafts were used in 398 patients with aorto-femoral occlusive disease and in 203 patients with aortoiliac occlusive disease. Straight tube grafts were implanted in 310 patients with abdominal aortic aneurysms. Small caliber straight tube grafts were used for femoral-femoral bypass in 112 patients. The remaining 17 patients received double-velour grafts for restoration of the renal (14) and superior mesenteric (3) artery circulation. In a review of patients, no dilatation or aneurysm formation was disclosed by clinical examination, sonography or aortography.
