In cardiac transplantation, chronic rejection takes the form of an occlusive vasculopathy. The mechanism underlying this disorder remains unclear. The purpose of this study was to investigate the role nitric oxide (NO) may play in the development of allograft arteriosclerosis. Rat aortic allografts from ACI donors to Wistar Furth recipients with a strong(More)
OBJECTIVE The outcome of thoracoabdominal or descending aortic aneurysm repair after preoperative demonstration of the artery of Adamkiewicz (ARM) by magnetic resonance angiography (MRA) was investigated. METHODS Between January 2000 and December 2001, 40 consecutive patients who had aneurysms of the thoracoabdominal or descending aorta underwent(More)
OBJECTIVE Percutaneous catheter drainage (PCD) is not always effective in a case of hemopericardium. Acute occlusion of catheter and cardiac perforation can happen more often. To perform subxiphoid pericardiotomy within a minute for emergency cases, we have done this procedure in a blind method after finger dissection by subxiphoid approach. We report the(More)
PURPOSE We evaluated the efficacy of magnetic resonance angiography (MRA) for detecting the artery of Adamkiewicz (AKA) and the vertebral level of its feeding arteries branching from the aorta. MATERIALS AND METHODS Eighty-two patients (67 men, 15 women; aged 34 to 86 years, mean age 68.6 years) with thoracic descending and thoracoabdominal aortic lesions(More)
Idiopathic pulmonary fibrosis (IPF) is characterized by slowly progressive respiratory dysfunction. Nevertheless, some IPF patients experience acute exacerbations generally characterized by suddenly worsening and fatal respiratory failure with new lung opacities and pathological lesions of diffuse alveolar damage. Acute exacerbation of idiopathic pulmonary(More)
Simple coverage of the left subclavian artery (LSA) in thoracic endovascular aortic repair (TEVAR) is still a controversial procedure. We present our modified strategy dealing with LSA in TEVAR. Hand-made stent grafts were placed more proximal beyond the LSA for 104 patients. In elective 76, preoperative LSA occlusion test was performed on 31 patients, and(More)
Open repair of aortic aneurysm causes spinal cord perfusion pressure to decrease due to the steal phenomenon from the bleeding of intercostal arteries and cross-clamping of the aorta. We attempted to perfuse the intercostal arteries for preoperative detection of the artery of Adamkiewicz using newly developed catheters. Fifteen patients underwent selective(More)
Resection of the inferior vena cava (IVC) is occasionally performed for patients with advanced malignancy in the retroperitoneum. In the current study, we assessed the oncological effectiveness of IVC resection combined with tumor resection. We also addressed peri- and postoperative complications associated with resection and reconstruction of the IVC.(More)
To investigate the natural course of type 2 endoleaks (T2Es) and to identify the risk factors associated with a persistent T2E after endovascular aneurysm repair (EVAR). The medical records of patients who underwent EVAR for the treatment of an atherosclerotic abdominal aortic aneurysm between October 2006 and December 2011 at our institute were reviewed.(More)
