- Repair of ruptured abdominal aortic aneurysms with bifurcated endografts: a single-center study(2014) QUEIROZ, Andre Brito; SCHNEIDWIND, Karina Paula Domingos Rosa; MULATTI, Grace Carvajal; SANTO, Fabio Rodrigues Ferreira Espirito; NETO, Paulo Sassaki; TORRES, Inez Ohashi; LUCCIA, Nelson DeOBJECTIVE: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS: Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for endovascular treatment was evaluated by computed tomography scanning and anatomical features were determined based on the method of treatment. RESULTS: From February 2012 to January 2013 (12 months), 28 consecutive patients (mean age 67.2 years, range 45-85 years) underwent treatment for ruptured abdominal aortic aneurysms at our hospital. Eighteen patients (64.3%) were suitable for and underwent endovascular treatment with bifurcated endografts (16 patients) or aortouniiliac endografts (two patients). Ten patients who were considered unsuitable for endograft repair underwent open repair. Seven patients were classified as hemodynamically unstable (Endovascular, 5; Open, 2), and 21 were classified as stable (Endovascular, 13; Open, 8). The overall 30-day mortality rate associated with endovascular treatment was 27.8% (stable, 18.7%; unstable, 40%) and the rate associated with open repair was 50% (stable, 37.5%; unstable, 100%). CONCLUSIONS: In this study, the suitability of patients for endovascular repair of ruptured abdominal aortic aneurysms was high and the overall results of endovascular treatment remain encouraging. Indeed, bifurcated endografts are a feasible option for treating anatomically eligible ruptured abdominal aortic aneurysms.
- Coil embolization of an excluded internal iliac artery aneurysm with rapid expansion via gluteal artery approach(2013) LUCCIA, Nelson De; SASSAKI, Paulo; SANTO, Fabio Espirito; ROSA, Karina; PUECH-LEAO, PedroThe aim of the paper is to describe open approach of gluteal arteries for coil embolization of internal iliac artery (IIA) aneurysm. We observed enlargement of the IIA to 5.8 cm at the four-year follow-up evaluation of a 78-year-old man who had undergone surgical abdominal aortic aneurysm repair during which the IIA had been ligated at its origin. Following dissection of the gluteal artery with the patient in the prone position, a catheter was placed inside the aneurysmal sac, and coil embolization was possible to exclude the aneurysm. Postoperative angio-computed tomography showed good coil positioning and no demonstrable blood flow or type 2 endoleak.
- Lateral approach to the peroneal artery without resection of the fibula for lower limb revascularization(2014) LUCCIA, Nelson De; QUEIROZ, Andre Brito; MULATTI, Grace Carvajal; SANTO, Fabio Rodrigues Ferreira Espirito; SASSAKI NETO, Paulo Isao; SCHNEIDWIND, Karina Domingos RosaThe peroneal artery is an important outflow vessel for lower limb revascularization and limb salvage. This vessel is commonly reached using a medial, posterior, or lateral approach with resection of the fibula. We present a technique of lateral approach to the peroneal artery without fibular resection.
