Incorporation of fibronectin-impregnated vascular prostheses in the pig. Microscope study.

An interface near the endothelial extracellular matrix is necessary to augment and maintain endothelial cell attachment. The use of plasma lectins constitutes one of the present lines of research designed to improve this interface. We studied the incorporation of 2 series of arterial prostheses with a diameter of 4 mm and a mean length of 9 cm.

[Surgical strategy in the association: aneurysm of the abdominal aorta and colonic lesion].

An association of an aneurysm of the abdominal aorta and a lesion of the colon raises an important question as to the correct sequence to follow. A simultaneous operation raises the major risk of infection and most authors prefer a sequential approach, treating either the aneurysm or the lesion of the colon first depending on the initial clinical situation or complications. In our first patient, both pathologies were known before surgery and simultaneous procedures were deliberately programmed.

Aortoiliac surgery and kidney transplantation.

Between January 1980 and December 1989, we performed 407 renal transplantations. Twelve of these patients (3%) underwent aortoiliac reconstruction before (Group I, two patients), concomitant to (Group II, five patients) or after (Group III, five patients) renal transplantation. The aortoiliac lesions treated included four aneurysms and seven occlusions of the abdominal aorta and one postarteriography dissection of the iliac artery.
