RESUMEN
PURPOSE: The purpose of the study was to demonstrate the feasibility of urgent endovascular treatment of a traumatic aortic isthmus rupture in a patient with an aberrant right subclavian artery. CASE REPORT: A 23-year-old man was admitted to a regional trauma center after a motor vehicle collision and found to have cerebral trauma and a large pseudoaneurysm of the aortic arch. Trauma computed tomography (CT) identified a blunt traumatic thoracic aortic injury with an aortic false aneurysm in the context of an aberrant right subclavian artery. A hybrid repair was performed with bilateral subclavian carotid bypasses and a double fenestrated physician-modified stent graft. The patient had an uneventful postoperative course. Postoperative CT scan showed sealing of the aortic arch rupture and patency of all the supra-aortic trunks. CONCLUSION: Endovascular repair of blunt traumatic thoracic aortic injury is considered first-line therapy. Aortic arch anomalies add complexity to treatment. This report demonstrates that a hybrid strategy with bilateral carotid-axillary bypasses and homemade double fenestrated endograft of the aortic arch is a valuable approach for this challenging emergency in the context of an aberrant right subclavian artery.

BACKGROUND: Soft tissue malignancy of lower limb can involve femoral triangle by direct tumoral invasion or secondary to ganglionic metastasis. Secondary arterial complications can appear during follow-up after initial tumoral resection and local radiation therapy. The aim of this study is to report our experience of secondary extra-anatomical lower limb revascularization following lower limb oncological resection with femoral bifurcation involvement. METHODS: This is a retrospective monocentric study including patients who underwent extra-anatomical iliopopliteal bypass, with a previous treated neoplasia involving homolateral femoral bifurcation. Proximal anastomosis was performed on the iliac artery, tunnelization was made through iliac wing, and distal anastomosis was done on distal superficial femoral or popliteal artery. RESULTS: Five patients underwent extra-anatomic iliopopliteal bypass for oncological purpose from 2008 to 2018 at our institution. Mean age at surgery time was 52 years (standard deviation = 19.3). Prosthetic graft was used in all cases. Primitive tumor involved Scarpa triangle in 3 cases (soft tissue sarcomas) and ganglionic metastasis involved Scarpa triangle in 2 cases (epidermoid carcinoma). Clinical presentation was ischemic in 4 cases and hemorrhagic in 1 case. One patient died during hospitalization. Of the 4 survivors, 3 patients had a patent bypass at the end of follow-up (2 had bypass thrombectomy, 1 patient had major amputation). CONCLUSIONS: Secondary iliopopliteal bypasses through the iliac wing following lower limb tumoral resection have acceptable results. It is a valid option for limb salvage especially after local radiation therapy and tumoral resection. Multidisciplinary management is necessary to obtain acceptable results and follow-up is mandatory.
