Combined aortofemoral and extended deep femoral artery reconstruction. Functional results and predictors of need for distal bypass.
In patients with combined aortoiliac and femoropopliteal occlusive disease, severe involvement of the deep femoral artery (DFA) has often been considered an indication for simultaneous aortofemoral and femorodistal bypass grafting. In 73 patients (87 limbs) with multilevel disease, extended DFA reconstruction was performed with aortofemoral bypass. Five-year actuarial patency of the reconstructions and overall five-year actuarial limb salvage were 62.2% and 60.2%, respectively. Of 20 variables tested, four were significantly associated with the functional outcome of the procedures. Multivariate analysis identified two factors as predictive of outcome independently from other variables: preoperative ankle-brachial pressure index and angiographic status of the below-knee popliteal artery. However, in case of reoperation for occluded aortofemoral graft, these factors lost their validity. Extended DFA reconstruction is a valuable and durable procedure able to provide an adequate outflow and distal perfusion. Careful judgment in each clinical situation will aid in selecting a small group of patients in which simultaneous femorodistal bypass is required.
