OBJECTIVES Patients with Stanford type B dissection who have been treated successfully with medical hypotensive therapy during the acute phase (< 14 days) have the risk of surgery during the chronic phase because of enlargement of the dissected aorta. The objective of this retrospective analysis is to determine the predictors of surgical indications for(More)
A 79-year-old woman was urgently referred to a district hospital with dull central chest pain after swallowing a fish bone. The bone was removed by esophagoscopy. Eleven days later she presented because of hematemesis. Computed tomography and aortic arch angiography confirmed a diagnosis of esophageal perforation leading to mediastinitis and the presence of(More)
OBJECTIVES In repair of acute type A aortic dissection, the type of proximal repair of the ascending aorta has been of great interest; however, very few reports are available regarding this issue in chronic aortic dissection. The surgical strategies for proximal repair in chronic dissection may not the same as those for acute dissection. We reviewed our(More)
In Marfan syndrome, there is a subset, called infantile Marfan syndrome, in which the disease is diagnosed during infancy and cardiac lesions including mitral regurgitation and aortic root dilatation tend to be deteriorated rapidly. In infantile Marfan syndrome, respiratory function is sometimes impaired when skeletal abnormalities such as scoliosis and(More)
OBJECTIVES The surgical treatment for thrombosed type A dissection is controversial because it has a better prognosis than with conservative therapy. We discuss the validity of conservative therapy for thrombosed type A dissection and examine the relationship between the morphology of the dissecting aorta and its operative indications. METHODS Subjects(More)
A 47-year-old woman was transferred to our hospital under endotracheal intubation with severe hemodynamic deterioration. A left mastectomy had been performed 8 months earlier and histology of the specimen showed malignant cystosarcoma phyllodes. An angiography and echocardiography suggested massive mass of the right ventricle extending to the pulmonary(More)
15 cases (31.6%) with closing aortic dissection have been experienced among 46 cases in acute dissecting aneurysm of the aorta during past 8 years and 9 months. Ulcer like projection was recognized in 81.8% of closing aortic dissection. Serum FDP level measured within 48 hours after onset was significantly lower and serum fibrinogen level was significantly(More)
Multichannel near-infrared spectroscopy (NIRS) could detect change in the regional cerebral oxygenation by following animated pictures of oxy-hemoglobin (OxyHb), deoxy-hemoglobin (DeoxyHb) and total hemoglobin in operations for three surgical cases of thoracic aortic aneurysm with selective cerebral perfusion (SCP). Simultaneously measured jugular venous(More)
A 3-year-old boy underwent a successful combined resection of a hepatoblastoma and its intracaval right atrial extension using a cardiopulmonary bypass. This type of extension is extremely rare in hepatoblastoma. The cardiopulmonary bypass enabled complete resection of the intracardiac mass of the hepatoblastoma. In addition, dissection and ligation of the(More)
