Selective cerebral angiography through the axillary artery.

The femoral artery approach to cerebral angiography has become well accepted. Some patients, however, are not candidates for femoral catheterization because of severe arteriosclerosis. One hundred cerebral angiograms were performed in 88 severely arteriosclerotic patients, using No. 5 French polyethylene catheters and the axillary approach. The technique, degree of success, patient population, and their complications are described. This approach allows selective vertebral and internal carotid artery injections. Only one serious complication occurred, thrombosis of the axillary artery. Because of the time saved, this technique is often preferable to the femoral approach in severely arteriosclerotic patients.

[Lipid metabolism of the patients with subarachnoid hemorrhage due to ruptured intracranial aneurysm--with special reference to the occurrence of cerebral angiospasm].

Lipid metabolism, which can be an important factor for arteriosclerosis, was studied in the patients with subarachnoid hemorrhage due to ruptured intracranial aneurysm. Total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride and Atherogenic Index were determined in 131 patients, who were admitted to our hospital since May, 1984 to March, 1986. Those results were analyzed in relation to the grading on admission, outcome and especially cerebral angiospasm. Serum levels of LDL-cholesterol and Atherogenic Index tended to correlate with the grading on admission. Total cholesterol, Atherogenic Index well correlated with the recovery of the patients and the activity of daily life. In this study, we especially examined the relationship with cerebral angiospasm. The results suggested that the role of cerebral arteriosclerosis caused by disturbance of lipid metabolism was rather negative to the development of cerebral angiospasm after subarachnoid hemorrhage.

Cerebral atherosclerosis in Japanese. Part 4: relationship between lipid content and macroscopic severity of atherosclerosis.

In order to evaluate chemically the macroscopic scoring methods for severity of arteriosclerosis in the cerebral arteries, concentrations of total lipids, esterified and free cholesterol and lipid phosphorus were compared to the macroscopic severity of lesions in the cerebral arteries obtained from 376 Japanese persons after unexpected death. An increase of cholesterol content was correlated significantly with an increase of Baker's score and/or Gore's atherosclerotic index. The correlation coefficient between Baker's score and total or esterified cholesterol was the highest among the tested correlations (r = 0.82, n = 376).
