Peroperative endoluminal dilatation or recanalization (DELPO or RCPO) in arteriopathies of the lower extremities. A new therapeutic weapon for the vascular surgeon. Apropos of 42 cases

: Forty-two DELPO or RCPO were performed using coaxial balloon catheters through surgical vascular approach for 35 cases of advanced lower limb arterial disease (stages: pronounced II: 6, III: 13, IV: 12, subacute ischemic: 4). The DELPO involved the following arteries: iliac: 12, deep femoral: 3, superficial femoral: 12, popliteal: 5, leg artery: 8, stenosis of popliteal anastomosis: 2, and was combined with a reconstructive arterial operation in 26 cases (proximal: 11 times, distal: 14 times or intersegmental: twice in relation to the surgical procedure). The DELPO was conducted alone in 9 cases and the RCPO alone in 6 cases, the surgical approach being preferred to the percutaneous route. Early results were rated as good in 89%, with clinical failures requiring amputation in 4% and failure of the method in 7%. The DELPO allows two objectives to be reached. First, when combined with a surgical procedure it reduces the extent and therefore the degree of surgical aggression while creating improved hemodynamic conditions for vascular reconstruction (improved proximal or distal beds or both). Second, when performed alone DELPO or RCPO enable safe, reliable treatment of lesions usually approached by a percutaneous endoluminal dilatation procedure.
