[Myocardial imaging with thallium -201 in the patients with coronary involvement after Kawasaki disease (author's transl)].

Coronary cine-angiography (CAG) was performed in 290 cases with the history of Kawasaki disease, in whom 57 cases (19.6%) were found to have coronary involvements. In 42 out of these 57 cases, myocardial imaging with thallium-201 (201Tl) was performed, and abnormal findings were seen in 6 cases. Five of these 6 cases showed not only coronary aneurysms, but also coronary obstructive lesions on CAG, while the remaining case showed only coronary aneurysms. The decrease of the uptake of 201Tl by the myocardium appeared to be mainly due to the decrease of regional myocardial blood flow, especially in those cases with obstructive lesions. Myocardial imaging with 201Tl seems to be more sensitive than stress electrocardiography by treadmill to detect myocardial ischemia in the patients with coronary obstructive lesions, although it seems less sensitive than stress electrocardiography to detect coronary arterial stenosis.

[Two-dimensional echocardiographic diagnosis of congenital malformations of the aorta in infants and children (author's transl)].

Two-dimensional echocardiographic studies were performed in 23 patients with coarctation of the aorta, 5 with interruption of the aortic arch, 6 with supravalvular aortic stenosis, 3 with truncus arteriosus, 2 with anomalous origin of the right pulmonary artery from the ascending aorta and 2 with aorto-pulmonary septal defect. The diagnosis was confirmed in each patient by surgery and/or cardiac catheterization and angiography. Visualization of the junction of isthmus and the descending aorta was possible in 18 of 23 patients with coarctation by two-dimensional echocardiography. In 13 patients correct diagnosis was obtained prospectively and in 2 patients coarctation was detected retrospectively. In only one of the 5 patients with interruption correct diagnosis was obtained and in 3 patients it was difficult to differentiate interruption from coarctation. In 5 of the 6 patients with supravalvular aortic stenosis, visualization of the area of obstruction was possible to two-dimensional echocardiography. In 2 of the 3 patients with truncus arteriosus, in whom none of the 2 had anomalous origin the right pulmonary artery from the ascending aorta and one of the 2 had aorto-pulmonary septal defect, correct diagnosis was obtained prospectively by two-dimensional echocardiography. Two-dimensional echocardiography may offer a useful noninvasive method for the direct visualization of aortic obstructive lesions and aortic malformations.

[Computed tomography in hypertensive cerebellar hemorrhage (author's transl)].

Fourteen cases of cerebellar hemorrhage were analysed from the point of CT-scan, and the following results were obtained. 1. The number of cases of cerebellar hemorrhage forms 4.4% of that of total intracranial hemorrhage. 2. Most of the cerebellar hematomas extend upward. Downward extension is rare. 3. In acute dead cases hematomas are 5 cm or more in diameter and lie over bilateral hemistpheres with the extension to third or fourth ventricles in CT-scans. 4. Slowly progressive cases are deteriorated by the secondary hydrocephalus. 5. In mild cases hematomas are 3cm or less in diameter on CT-scans and the hematoma evacuation is not indicated for these cases. 6. The shunt operation alone is sufficient for the life saving of the slowly progressive cases, but the hematoma evacuation is indicated in these cases if the functional prognosis is taken into consideration. 7. Immediate hematoma evacuation together with the ventricular drainage is considered to be effective for the life saving of the acute fulminant cases.
