RESUMO
The aim of this report is to present our experience with new techniques for extraanatomic lower limb arterial reconstruction. Two techniques are described here of construction of an extraanatomical bypass for lower limb revascularization either through the wing of the iliac bone or underneath the iliopsoas fascia through the muscular lacuna close to the anterior superior spine of the iliac crest. Both techniques are recommended for the treatment of a severely injured groin, such as in patients with pelvic malignancy and/or an acute groin bleeding due to postirradiation femoral artery erosion or an infected femoropopliteal bypass graft with severe upper medial thigh sepsis. These techniques were used in nine patients (five with malignancy and four with an infected femoropopliteal bypass graft). Our results showed that the transosseous route through the wing of the iliac bone or underneath the iliopsoas fascia through the muscular lacuna may be considered effective alternate routes for lower limb arterial extraanatomic reconstruction when the common femoral cannot be used for arterial inflow.
