[Semiclosed endarterectomy of the aorto-femoral segment by Vollmar loops]

In 1996-1998 131 patients were observed who underwent semiclosed loop endarterectomy of the aorto-femoral segment by Vollmar loops. The control group consisted of 220 patients on whom the operations of uni- or bilateral aorto-femoral bypass with synthetic prostheses were made. The semiclosed loop endarterectomy was mainly fulfilled through the femoral access, the retroperitoneal access was used in 18.3% of the patients. Thus the time of operation was as short as (100 +/- 10.9) min. in mono- and (118.6 +/- 12.9) min. in bilateral reconstructions, and blood loss in typical cases was not more than (327 +/- 24.1) ml. The operation of semiclosed loop endarterectomy gave a high level of patency to the reconstructed aorto-femoral segment. The primary 5-year patency of the iliac arteries was 91.86%, the cumulative one--93.87%. Such parameters for shunting operations were lower: 75.4 and 81.63% respectively (p < 0.05).
