OBJECTIVE Persistent Type 2 endoleaks (PT2) after endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) are associated with increased adverse outcomes, including aneurysmal sac enlargement and rupture. The aim of this study was to report early clinical outcomes of coil embolization (CE) to aortic branched vessels prior to EVAR and(More)
BACKGROUND Coronary perforation (CP) is a rare, but sometimes lethal, complication of percutaneous catheter intervention (PCI). We reviewed surgically-treated cases of type 3 CP during PCI. METHODS AND RESULTS From 2007 to 2010, 5 patients underwent surgical repair for type 3 CP (3 men, 2 women; mean age, 74 years). The mean number of diseased coronary(More)
BACKGROUND We previously reported effectiveness of coil embolization (CE) to aortic branched vessels before endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) because of significant shrinkage of aneurysmal sac. In this study, we investigated EVAR cases to clarify influential factors of aneurysmal shrinkage and enlargement. METHODS 148(More)
OBJECTIVE The aim of this study was to evaluate the midterm clinical outcomes of various approaches, including hybrid procedures, to aortic arch pathologies. METHODS Of 305 consecutive patients who underwent aortic arch repair between 2005 and 2013, 244 underwent conventional open total aortic arch repair (CTAR) with antegrade cerebral perfusion under(More)
BACKGROUND Abdominal aneurysmal sac enlargement after endovascular aortic repair (EVAR) is a critical issue. However, the predictors have not yet been fully determined. Although unrecognized, intraluminal thrombus volume (ITV) is an important index. Therefore, we retrospectively evaluated the correlation among preoperative ITV, residual type II endoleak,(More)
PURPOSE Endotoxin adsorption treatment (direct hemoperfusion using a polymyxin-B immobilized fiber column, or PMX-DHP) is now considered a useful option for treating severe sepsis. However, the efficacy of PMX-DHP for infective endocarditis (IE), in which the causative microorganisms are usually gram-positive cocci, remains unclear. In the present study, we(More)
A spontaneous intercostal arterial rupture in patients without associated illness or trauma is extremely rare. We present a 58-year-old man with an idiopathic and spontaneous arterial rupture restrained by conservative management. He was admitted to our institute with an intermittent back pain lasting for 3 days. His past history included no notable(More)
Giant sinus node artery aneurysms with a fistula into the left atrium are extremely rare. A 76-year old woman was admitted to our hospital for an abnormality on her chest X-ray. Coronary computed tomography (CT) angiogram revealed a giant coronary aneurysm with feeding arteries arising from the sinus node artery and the left circumflex artery. Additionally,(More)
BACKGROUND AND AIM The aim of this study is to evaluate acute kidney injury (AKI) after total aortic arch repair (TAR) with moderate hypothermic circulatory arrest (MHCA) and selective antegrade cerebral perfusion (SACP). METHODS A retrospective analysis was performed in 200 patients who underwent TAR with HCA and SACP between 2008 and 2012. The AKI(More)
