[Contralateral shunt of a restored aorto-iliac axis for atheromatous aorto-iliac lesions (author's transl)].

Reparative surgery of an iliac axis was conducted on 35 patients with atheromatous aorto-iliac lesions, and was completed by a contralateral shunt as an "alternative" between a prosthesis and a bifemoro-aortic thromboendarteriectomy. Reconstructive surgery on the donor axis included a thromboendarteriectomy alone or combined with a venous graft in 31 cases, an aorto-femoral vein graft in 3 cases, and an external iliac angioplasty in 1 case. The contralateral shunt was by a vein graft in 29 patients, and a prosthesis in the other 6 cases. Two complications occurred, one due to progression of the atheromatous lesions on the unobstructed aorto-iliac axis, the other being related to fibrous stenosis of a crossed vein graft. Post-operative follow-up over periods ranging from 6 months to 6 years confirmed the good vascular prognosis.
