Abstract
Our experiences of cerebral angiography in acute stage of ruptured aneurysms were 127 cases in 1982-1984 and in only one case rerupture during angiography occurred. Our principle for cerebral angiography in acute stage of ruptured aneurysms is as follows:
1) Control of blood pressure. Systolic pressure should be under 120 using trimetaphan and nifedipine
2) Sedation must be done sufficiently
3) The operator must be skilled in order to minimize the mechanical damage to the patient
4) Direct puncture using teflon needle and slight slow injection by manual
5) Non-ionic contrast medium metrizamide is very useful because of no discomfort and no pain to the patient.
