ABSTRACT

Aortoiliac occlusive disease (AIOD) can be difficult to treat. We performed aorto-uni-iliac (AUI) stent-grafting with external-iliac artery crossover bypass in 3 cases of extensive AIOD (mean age 69 years). Lesions were TASC II type D in 2 and D+A in 1. Mean ankle-brachial index of diseased side was 0.52. Bare stent placement for iliac stenosis was also done in 2 cases. All cases were a technical success with no complications. Mean operation time was 123 min and mean hospital stay was 11 days. We have been keeping good patency. We consider it an effective treatment option for AIOD.

ABSTRACT

We report a case of operations using a hybrid technique for repeated extensive aortic aneurysm. A 71-year-old man had extensives aneurysms of the aortic arch and descending aorta. In the first operation, he had undergone thoracoabdominal aortic replacement with island repair for thoracoabdominal aortic aneurysm (Crawford type 3) at age 64. Six years later, computed tomography showed an aortic aneurysm around the region of the island repair and penetrating atherosclerotic ulcer (PAU). Therefore, he underwent abdominal debranching and thoracic endovascular aortic repair (TEVAR) at 70 years old. At the same time, he had an extensive aortic arch aneurysm. Considering the complicated surgical history and the affected region, we judged that conventional graft replacement was difficult. So, in the third operation, we performed TEVAR for the descending aorta at 71 years old. One month later, total arch replacement (TAR) with a frozen elephant trunk (FET) was performed (4th operation). The patient was discharged home 22 days after the 4th operation. This strategy of operations using hybrid techniques for extensive aortic aneurysm may be useful in high risk cases of surgical procedures and postoperative complications.

ABSTRACT

Between August 2008 and June 2012, 17 TEVAR procedures for thoracic aortic aneurysms (TAA) requiring Z2 coverage were performed at our institution. Patient age ranged from 46 to 82 years old (mean 69.4), 16 were male. Criteria for LSA revascularization at our institution are defined as either : 1) dominant left vertebral artery (VA), 2) absent or diminutive or occluded right VA, 3) no communication of bilateral VA, 4) bilateral carotid artery disease, 5) patent LIMA-coronary bypass, 6) if a long length of the thoracic aorta is covered. Devices utilized were Gore TAG (<i>n</i>=12) and TX2 (<i>n</i>=5). Deployment of the stent-graft (SG) was successful in 17 cases (100%) and complete thrombosis of the aneurysm or complete entry closure was achieved in 16 cases (94.1%). Axillo-axillar cross over bypass (Ax-Ax B) was performed in 5 cases (29.4%). There was no instance of cerebrospinal ischemia or hospital death and the mean follow-up was 22.9 month (range 5 to 46). One case was converted to open surgery due to secondary type 1 endoleak. There was no instance of Ax-Ax B graft occlusion or aneurysmal rupture. The initial and mid-term results of TEVAR requiring Z2 coverage were satisfactory, and we believe that our criteria for LSA revascularization played an important role in providing the satisfactory results.

ABSTRACT

We report a patient who underwent an operation for an infectious abdominal aortic aneurysm 10 months after intravesical bacillus Calmette-Guerin therapy. A 68-year-old man had previous gastrectomy for early gastric cancer and intravesical BCG therapy for early stage urinary bladder cancer. His follow up CT scan revealed an abdominal aorta pseudoaneurysm. We performed aneurysmectomy, omentopexy and bilateral axillo-femoral bypass. The culture of an abscess in the aneurysm identified <i>Mycobacterium bovis</i>. The patients improved clinically with antituberculosis agents after operation. Intravesical bacillus Calmette-Guerin therapy is effective in the treatment of early stage urinary bladder cancer. Although this treatment is generally considered safe, serious complications including vascular complications have been reported.

ABSTRACT

We reporte the initial results of open stent-grafting (OSG) applied with a Matsui-Kitamura (MK) stent in the treatment of thoracic aortic aneurysm (TAA). From August 2005 to March 2011, OSG for TAA was applied in 35 cases (male/female, 29/6, 58∼86 years old, mean age 71). During deep hypothermic circulatory arrest with antegrade selective cerebral perfusion, the stent graft was delivered through the transected proximal aortic arch, followed by arch replacement with a 4-branched prosthesis. Concomitant procedures included 1 coronary artery bypass graft, 1 mitral valve replacement and 2 pacemaker implantations. Operative mortality within 30 days was 5.7% (respiratory failure in 1 and ischemic enteritis in 1). There was 1 in-hospital death due to brain stem infarction. Perioperative morbidity included 2 (5.7%) stroke, 5 (14.3%) spinal cord injuries (paraplegia in 1, paraparesis in 1 and transient paraparesis in 3) , and 1 (2.9%) temporary hemodialysis. Ten patients (28.6%) were intubated for more than 72 h. There was no complication with the graft-related incident. These initial results suggested the OSG method applied with a MK stent is a useful surgical procedure for the treatment of TAA.
