[Aneurysms of the popliteal artery. Our experience apropos of 37 cases]. / Gli aneurismi dell'arteria poplitea. Nostra esperienza a proposito di 37 casi.

The authors describe their experience concerning the surgical treatment of aneurysmatic pathology of the popliteal artery. This is the most frequent site for aneurysm after aortic aneurysm. Since 1979 to 1994, 26 patients, 21 men and 5 women (mean age 65.8 years), have been treated at the Institute of Clinical Surgery of the University of Ferrara for a total of 37 popliteal aneurysms. Thirteen patients had more than one aneurysm. Before the operation, all patients underwent DSA, and echo Doppler, 7 with CAT and 4 with RMN. Twenty-nine substitutions, 7 by passes and 1 ligation were performed. Twelve of the 29 substitutions were made by reversed saphenous vein. Fourteen by PTFEe, and 3 by dacron. In 4 cases it was necessary to reimplant either the anterior tibial artery (3 cases) or the posterior tibial artery (1 case) separately. The results obtained were good especially in the post-trauma patients. Only 3 amputations were necessary due to graft obstruction immediately after surgery, and in post-traumatic conditions.
