PURPOSE 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). METHODS 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(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)
BACKGROUND We reviewed our experience to investigate the determinants of paraplegia/paraparesis after endovascular stent-graft repair of the thoracic aorta, to assess the influence of the artery of Adamkiewicz (ARM) detected by preoperative magnetic resonance angiography (MRA) and to identify patients at risk. METHODS Over a 5-year period (March 2001-June(More)
OBJECTIVE It remains controversial whether video-assisted thoracoscopic surgery (VATS) major pulmonary resection (VMPR) with systematic node dissection (SND) is a feasible approach for clinical N0 and pathological N2 non-small cell lung cancer (cN0-pN2 NSCLC). We compared the clinical outcome of patients who underwent VMPR with SND for cN0-pN2 NSCLC with(More)
BACKGROUND The mortality of patients with descending thoracic aortic rupture who are treated by conventional surgery is high. Our current strategy for the management of descending thoracic aortic rupture is to treat seriously ill patients with endovascular stent-grafting using handmade grafts, and to treat other patients with traditional open repair. The(More)
Both paradoxical intracranial embolism, an intracranial arterial embolism caused by venous embolic material that has passed through a right-to-left shunt, and pulmonary arterial embolism are life-threatening complications of joint arthroplasty. We report a case of severe paradoxical intracranial embolism and pulmonary embolism that occurred during hip(More)
PURPOSE Although a diagnosis of mesenteric necrosis can easily be made, mesenteric ischemia is sometimes overlooked, especially in the acute phase. We experimentally evaluated the time course of the lactate concentration, which may be a possibly useful variable in making a diagnosis of mesenteric ischemia, and determined how an early diagnosis can be made.(More)
BACKGROUND In spite of recent improvements in treatment for acute aortic dissection, mesenteric ischemia secondary to aortic dissection is still challenging. We propose a simple screening method to detect mesenteric ischemia secondary to acute aortic dissection. METHODS From 1991 to 2002, 245 patients with acute aortic dissection were admitted to our(More)
BACKGROUND Although previous reports have described the repair of distal aortic arch aneurysms through debranching and chimney techniques, these methods invariably involve surgical management of the carotid artery. We report clinical results of thoracic endovascular aortic repair (TEVAR) using fenestrated stent grafts in the treatment of aortic arch(More)
OBJECTIVE Impaired glucose tolerance (IGT) in association with insulin resistance is considered to be a risk factor for atherosclerosis. Thus, patients with IGT may have abnormal lipid and lipoprotein profiles. The purpose of this study was to investigate presence of remnant-type hyperlipoproteinemia in patients with IGT.
