[A 10-year follow-up study of bypass operations with double-velour dacron in the aortoiliofemoral position].
The results of the follow-up study of 271 bypass operations in aortoiliofemoral position are analyzed. The interventions are done using monotype double-velour dacron prosthesis, standard operative technique and tactics. At 5.4 percent operative lethality, the postoperative complications include infection (2%) and rethrombosis (4%), necessitating reoperation which is successful in 64 per cent. Secondary cumulative patency of the prostheses implanted, amounting to 90 percent at three years, 80 percent at 5 years, and 66 percent at ten years postoperatively, is recorded, with aortobifemoral bypasses yielding superior results. Serious late complications are registered, such as prosthesis infection, abnormal dilatation of the implant, periprosthetic seromas and aneurysms by anastomosis. The underlying causes of complications and the indications for reoperation are discussed. The role played by late reoperations, leading to a successful outcome in 63 percent of cases is underscored. Attention is called to a number of characteristic features of the prosthesis employed, including the need of precise preclotting, restrained post-implantation increase in its diameter up to 20 percent necessitating implantation of prostheses isodiametric to the recipient artery, high incidence of postoperative complications making mandatory, periodic check-ups of operated patients and the like. In conclusion, it is estimated that over the 10-year observation period, the prosthesis suggested yields satisfactory results upon implantation in the aortoiliofemoral segment, and these results may be accepted as a basis for comparison with new vascular prosthesis designs.
