Successful off-label use of the GORE EXCLUDER Iliac Branch Endoprosthesis to preserve gluteal perfusion during staged endovascular repair of bilateral isolated hypogastric aneurysms.

Endovascular repair of iliac artery aneurysms has emerged as an alternative to traditional open surgical repair. Although there is little consensus on indications to preserve hypogastric blood flow during aneurysm repair, it is well understood that complications from bilateral hypogastric occlusion may be significant. The GORE EXCLUDER Iliac Branch Endoprosthesis (W. L. Gore and Associates, Flagstaff, Ariz) received United States Food and Drug Administration approval in March 2016 for treatment of common iliac artery and aortoiliac aneurysms. This case report discusses an off-label use of GORE EXCLUDER Iliac Branch Endoprosthesis to maintain pelvic perfusion during treatment of bilateral internal iliac artery aneurysms without surrounding aortoiliac pathology.

Lower extremity bypass with tumescent local anesthesia.

Lower extremity bypass is most commonly performed for the treatment of critical limb ischemia. These patients often pose high surgical risk secondary to significant clinical comorbidities. These risks may be compounded when general anesthesia is considered. We present the case of a patient at high anesthesia risk with critical limb ischemia who was unable to receive general anesthesia or neuraxial blockade. An infrainguinal bypass was performed using tumescent anesthesia with minimal intravenous sedation. The patient was discharged 6 days later, and his postoperative course was complicated by a groin lymphocele. Tumescent local anesthesia is a possible alternative pain management strategy for patients undergoing lower extremity bypass surgery.

Primary leiomyosarcoma of saphenous vein presenting as deep venous thrombosis.

Only a small number of venous leiomyosarcomas have been previously reported. Of these tumors, those of saphenous origin comprise a minority of cases. A 59-year-old man presented with symptoms of deep vein thrombosis and was eventually diagnosed with primary leiomyosarcoma of great saphenous vein origin. The tumor was treated with primary resection and femoral vein reconstruction with autologous patch. Although extremely rare, saphenous leiomyosarcoma can present as deep vein thrombosis. Vascular tumors should be included in the differential diagnosis of atypical extremity swelling refractory to conventional deep vein thrombosis management.
