Objectives: Squamous cell carcinoma (SCC) of the penis with inguinal lymph node involvement aggravates prognosis and can cause femoral artery bleeding, hemorrhagic shock and even death. The objective of this study is to describe the use of extra-anatomical transobturator bypass graft for femoral artery involvement by metastatic carcinoma of the penis.
Casuistic And Method: Five patients with SCC and inguinal lymphatic metastasis involving the femoral vessels, who underwent extra-anatomical arterial bypass through obturator foramen between 1999 and 2007, were reviewed. The surgical technique and the postoperative outcome were described.
Results: After extra-anatomical transobturator bypass, all patients presented distal pulses. The mean time of surgery was 6 h. In four patients, a knitted Dacron tube was used; and in one, the contralateral devalvulated greater saphenous vein was used. Concomitantly, two patients underwent mass resection and one patient underwent node dissection 2 weeks after bypass. Two patients chose not to undergo inguinal resection, opting for palliative chemotherapy after the vascular procedure. The average follow-up period was 12 months and four patients have died-three due to pulmonary metastasis, and one due to acute myocardial infarct. No prosthetic complication was identified and no patient presented femoral bleeding.
Conclusions: The use of the transobturator bypass can benefit patients presenting with penile SCC and inguinal lymph nodes metastasis involving the femoral vessels, allowing resection of extensive tumor lesions, as well as avoidance of local complications.

Introduction: Infra-inguinal vascular reconstruction with active groin infection is a concerning issue. Using resistant grafts to infection is the most adopted approach. However, in absence of these materials in acute situations, the trans-obturator approach allows for limb revascularisation avoiding the infected site.

When managing an infected groin, though rarely performed, a transobturator bypass remains an important alternative in the armament of a vascular surgeon. Autologous vein and synthetic PTFE are known conduit options for obturator bypasses, although the advantage of utilizing an autologous biological conduit when dealing with infection may not be an option for every patient. On literature review, bovine carotid grafts have been used in infrainguinal revascularizations with comparable results to autologous vein; however, no cases can be found for its use in obturator bypass thus far.

Introduction: Biosynthetic prosthesis has become the trend to carry out arterial reconstruction in infected sites since considered to be resistant to infection. Late graft occlusion is the only complication reported in literature so far. We report a case of biosynthetic graft infection which led to early detachment of the femoral anastomosis of a femoral-popliteal above-knee bypass.

Introduction: Transobturator bypass is an older and less frequently performed revascularization of the lower extremity that is useful in the setting of multiple failed lower extremity bypasses usually due to groin sepsis and infection(s). It can be a technically challenging operation due to anatomic constraints.
Report: We describe a successful transobturator bypass utilizing fluoroscopy for passage of bypass tunneler and graft through the obturator foramen.
