[Proximal anastomotic pseudoaneurysms].

Abdominal aortic pseudoaneurysms development in patients submitted to endoaneurysmectomy or bifurcated aorto-peripheral by pass was, for a long time, considered a rare complication of aortic surgery. In old papers it was referred prevalence of abdominal PSA which rambled on values less than 1%. The diagnosis was always reached in concomitance with fissurations, ruptures or aorto-digestive fistulas. Recent papers, in which were reported results of accurate instrumental (echo and TC) follow-up of patients with aortic prosthesis, demonstrated a really higher prevalence of abdominal aortic pseudoaneurysms (about 6%). A retrospective analysis of PSA admitted to the General and Cardiovascular Institute of the University of Milan and the First Surgical Division of the General Hospital of Treviglio-Caravaggio (BG), demonstrated a high morbidity and mortality of complicated aortic pseudoaneurysms surgery. Considering the data reported in the international literature and the results of the surgery of complicated aortic PSA, the Authors point out the necessity of accurate periodical instrumental follow-up of subjects with aortic prosthesis in order to identify anastomotic pseudoaneurysm and to evaluate incidental evolution of aneurysmatic disease.
