Re: "Trans-iliac Bypass Grafting for Vascular Groin Complications" We read with much interest the article about your experience with Trans-Iliac Bypass Grafting for Vascular Groin Complications. 1 The last case of extra-anatomic bypass we performed because of groin complication was a 68 year old man treated in another hospital by excision of an undifferentiated pleomorphic sarcoma involving the groin. We first performed an endovascular repair of the common femoral artery by a contralateral approach, as it was bleeding in the ongoing groin infection (the profunda femoris artery was surgically ligated during the previous excision intervention). After 8 months follow up, the groin wound healed completely but femoral stent occlusion led to acute lower limb ischaemia (Fig. 1A).
