Two cyanotic patients had venoarterial shunting from the inferior vena cava to the left atrium in an uncomplicated atrial septal defect with normal right ventricular pressures. Cyanosis was due to a large, anomalous inferior vena caval valve, the eustachian valve. The mechanism of cyanosis and technical problems for surgical repair are discussed.
BACKGROUND/AIMS To investigate the effect of acute hyperbaric oxygen therapy (HBOT) on post-operative sinusoidal endothelial cell (SEC) damage caused by activated neutrophils. METHODOLOGY 12 non-cirrhotic patients (Group H), who underwent elective hepatectomy for liver cancer, were given 2 courses of HBOT: 2.0 atm with inhalation of 100% oxygen, for 60(More)
The purpose of the study was to assess the signal intensities of arachnoid granulations within the dural sinuses using the FLAIR sequence for differentiation of space-occupying lesions in and adjacent to the dural sinuses. We retrospectively reviewed MR images of the brain of 1118 consecutive subjects, ranging in age from 0 to 93 years (mean 57.2 years).(More)
OBJECTIVE The purpose of this study was to assess the characteristics of Tornwaldt's cysts as revealed by routine MR studies. MATERIALS AND METHODS We retrospectively reviewed MR images of the brain in 1208 consecutive subjects who ranged in age from 3 weeks to 93 years (mean, 57.1 years). The signal intensity, shape, and size of Tornwaldt's cysts were(More)
Background: The purpose of this study was to evaluate computed tomographic (CT) findings for predicting the presence of intestinal necrosis in patients with closed loop and strangulating obstruction of the small bowel. Methods: Twenty-five patients with surgically confirmed closed loop and strangulating obstruction were divided into two groups with (n= 16)(More)
A 49-year-old man had episodes of angina pectoris in the middle of the night only when he had ingested alcoholic beverage in the evening. Electrocardiograms at rest and after exercise were completely normal. An anginal attack with remarkable ST elevation in leads V1 through V5 was successfully provocated every night when he ingested alcohol and no attacks(More)
A 40-year-old woman of atrial septal defect associated with idiopathic thrombocytopenic purpura (ITP) was successfully operated upon under cardio-pulmonary bypass. Steroids had been given preoperatively, resulting in an increase of the platelet count from 0.7 X 10(4)/mm3 to 20.6 X 10(4)/mm3. Steroids could be withdrawn before the operation. No bleeding(More)
Noninvasive pulsed Doppler echocardiography combined with two-dimensional echocardiography by the right parasternal approach was performed to detect the shunt flow through the defect in 31 patients with suspected secundum atrial septal defect (ASD). A defect of the interatrial septum was seen on the two-dimensional echocardiograms of 30 of 31 patients. In(More)
Left-sided inferior vena cava (IVC) was identified preoperatively in the case of abdominal aortic aneurysm. At operation, the left-sided IVC and bilateral common iliac veins were severely pressed by the huge aneurysm, and the walls of these vessels were thin and fragile at the site adhered to the aneurysm. Careful dissection around the common iliac arteries(More)
