- Arterite actínica de artéria subclávia: relato de caso e revisão de literatura(2012) BELCZAK, Sergio Quilici; BEHAR, Nino; SINCOS, Igor Rafael; CAVAQUINI, Thiago José; NERING, Gilberto; AZEVEDO, Caio; SLAVO, Luis Felipe; AUN, RicardoSeveral complications may occur as a consequence of adjuvant radiotherapy for cancer. One of these complications is actinic lesions of the subclavian artery in patients undergoing radiotherapy for breast cancer; however, there are few reported cases. In the present case report, we describe a case of right subclavian artery occlusion in a patient undergoing radiotherapy for breast cancer. Occlusion was treated by means of conventional artery bypass with interposition graft with polytetrafluoroethylene (PTFE). Our extensive review of the literature revealed 12 reported cases showing the different treatment options performed. We concluded that actinic arteritis of the subclavian artery is an uncommon condition; however, its presence should be considered in all patients with upper limb ischemia who underwent radiotherapy.
- Correção endovascular de aneurisma de aorta abdominal e artéria ilíaca comum esquerda em paciente com hemofilia C grave(2012) BELCZAK, Sergio Quilici; SINCOS, Igor Rafael; AUN, Ricardo; MIOTO NETO, Boulanger; LOBATO, Manoel; SALITURE, Fernando; LEDERMAIN, AlexFactor XI deficiency, also known as hemophilia C, is a rare hereditary blood disease that manifests with persistent bleeding after surgery, trauma, menorrhagia, and dental extractions. This article reports an endovascular repair of a patient diagnosed with an aortic and left common iliac aneurysm, with severe factor XI deficiency (factor XI activity below 20%). The procedure was successfully performed with management of the coagulation disorder by preoperative and postoperative infusion of plasma and laboratory control of the coagulation.
- Endovascular repair of a traumatic arteriovenous fistula involving the iliac bifurcation using an iliac branch device(2012) QUEIROZ, Andre Brito; MULATTI, Grace Carvajal; AUN, Ricardo; VALENTIM, Luisa Assis; PUECH-LEAO, PedroEndovascular techniques have shown to be useful in the management of vascular injuries because they transform a complex and potentially dangerous procedure into a safe one. We present the case of a 39-year-old man with congestive heart failure and abdominal bruit 11 years after an abdominal gunshot wound. Imaging studies revealed an arteriovenous fistula involving the left iliac artery bifurcation, and an iliac branch device was used to treat it. Symptoms resolved, and follow-up imaging showed patency of the graft and closure of the arteriovenous communication. To our knowledge, this is the first report of a nonaneurysmal disease treated with this device. (J Vasc Surg 2012;55:1474-6.)
- Mycotic aneurysm of the tibioperoneal trunk: a first manifestation of an infected endocarditis(2012) BELCZAK, Sergio Quilici; SINCOS, Igor Rafael; TEIVELIS, Marcelo Passos; OLIVEIRA, Carlos Alberto Sian de; FRAGOSO, Helio; AUN, RicardoInfrapopliteal mycotic aneurysm resulting from endocarditis is rare, with only a few reported cases. We describe the case of a 28-year-old male patient who was suffering with pain and edema in the right leg. The ultrasound revealed an aneurysm of the right tibioperoneal trunk and a deep vein thrombosis (DVT). The patient was admitted and developed acute congestive heart failure, being diagnosed with possible endocarditis. A pseudo-aneurysm was revealed by arteriography. Aggressive antibiotic treatment was initiated, and open surgery confirmed a mycotic pseudo-aneurysm of the tibioperoneal trunk. To our knowledge, this is the 8th case reported of an infected aneurysm in this particular location.
