PURPOSE To assess the significance of aortic remodeling in the prevention of the late aortic events after thoracic endovascular aortic repair (TEVAR) for aortic dissection. METHODS The study involved 52 patients (41 men; mean age was 59.7±13.3 years) with type B aortic dissections and patent false lumens treated with TEVAR between 2004 and 2011. Of the 52(More)
Toxic adenoma and toxic multinodular goiter (TMNG) are common causes of hyperthyroidism in iodine-deficient regions, but they are relatively rare in iodine-sufficient regions, including Japan. Constitutive activating mutations of the thyroid stimulating hormone receptor (TSHR) gene and adenylate cyclase-stimulating G α protein (GNAS) gene are frequent in(More)
[n]Cycloparaphenylenes (n = 8-13, CPPs) were synthesized, and their physical properties were systematically investigated. [8] and [12]CPPs were selectively prepared from the reaction of 4,4'-bis(trimethylstannyl)biphenyl and 4,4''-bis(trimethylstannyl)terphenyl, respectively, with Pt(cod)Cl(2) (cod = 1,5-cyclooctadiene) through square-shaped tetranuclear(More)
OBJECTIVES Stent graft-related complications, including endoleaks and graft migration, are partly attributed to insufficient graft attachment to the aortic wall. ONO-1301, a stable synthetic prostacyclin agonist, reportedly reorganizes extracellular matrices, enhancing tissue healing. We hypothesized that ONO-1301-eluting stent grafts may strengthen graft(More)
Kimura disease (KD) affecting an unusual site is a diagnostic challenge. We report herein the case of a 62-year-old Japanese woman who presented with swelling of the epiglottis, resulting in airway narrowing. Microscopically, biopsied and resected specimens both revealed lymphoid proliferation of a reactive immunophenotype, accompanied by vascular(More)
We report the first successful hybrid endovascular technique for treating a residual dissecting thoracoabdominal aortic aneurysm with a compressed true lumen in a 48-year-old man in whom multiple stent grafts were deployed through the false lumen. The first stage of the procedure involved debranching of the visceral vessels from the right external iliac(More)
BACKGROUND Treatment outcome was evaluated in patients who underwent breast-conserving therapy and tangential irradiation. After verifying background factors including systemic therapy, the clinical efficacy of postoperative irradiation was investigated. METHOD There were 708 study subjects, all of whom had early breast cancer treated between 1992 and(More)
We report a new hybrid aortic arch repair procedure for the treatment of extensive thoracic aortic aneurysms involving the ascending aorta, arch, and descending aorta. In the first stage of this procedure, a "double-barrel tube graft" was inserted into the ascending aorta and fixed to the sinotubular junction under short-duration cardiopulmonary bypass in(More)
