    Abstract:
    This study is aimed at analyzing our experience in the evolution of aneurysmatic disease after surgical treatment of the typical subrenal abdominal aortic aneurysm. In fact in some cases we reobserved these patients for the onset of a new important dilatation involving the proximal tract of the abdominal aorta or the common iliac arteries. From 1980 to December 1992, 24 patients out of a group of 1508 patients previously submitted to an aorto-aortic or aorto-iliac reconstructive procedure using dacron prosthetic grafts were reoperated for relapsing aneurysmatic disease. In six cases the dangerous ectasia was located above the proximal aortic anastomosis; in four patients the re-reconstructive procedure was performed clamping the subdiaphragmatic abdominal aorta and performing the proximal anastomosis just below the ostia of the renal arteries. In two cases the aneurysmatic process involved the origins of the visceral vessels and a left thoracophrenolaparotomic access was necessary in order to perform a thoracoabdominal reconstruction reimplanting the visceral arteries on the prosthetic graft. In 18 cases the progressive aneurysmatic process involved the common iliac axis provoking, in some cases, a kinking or a shortening of the aortic prosthetic graft. The results of these reintervention are good with no mortality at operation and a satisfactory middle term (average 3 years) follow-up. Our investigation demonstrates that in a small, but significant (1.6%) percentage of patients the aneurysmatic disease spreads upward and downward involving arterial segments formerly non affected.
