[Coverage of an infected Deep femoral arteria vascular graft bypass by pediculated chimeric antero- lateral thigh flap associated with a vastus lateral muscle]. / Couverture d'un pontage par allogreffe de l'artère fémorale profonde par un lambeau pédiculé chimérique antérolatéral de cuisse associé au muscle vaste latéral.

Scarpa triangle defects with exposure of femoral bypass are challenging to treat. The authors present the case of a 46 years-old male with a groin defect of 10×18cm with an exposure on 5cm of an allograft of the deep femoral artery. Bypass was performed in emergency because of a limb ischemia with deep femoral artery thrombosis and aneurysm of the superficial femoral artery. The reconstructive surgery may propose a large musculo-cutaneous flap to fill the dead spaces surrounding the infected bypass, the flap should be vascularized by the deep femoral arteria, could not be the rectus abdominals flap because of the precedent abdominal incision. The homolateral pediculated ALT-flap with vastus lateral component appeared to be a good solution because of its versatility and the low morbidity of the donor site.
