Abstract

Since cerebral angiography is pioneered by Egen Maniz in 1927, the technique and method have been very much improved. Cerebral angiography is very important examination togather with pneumoencephalography not only preoperative diagnostic procedure in brain tumor, head trauma, cerebral vascular anomaly and cerebral hemorrhage etc. but also to detect the brain physiology. Today, most of cerebral angiographic examinations are made using rapid cassette changer, usually 2 pictures per a second for 6. seconds in AP and lateral projections, altogather 24 pictures are taken. In special case 6 pictures per a second is taken. It is necessary to use Lisholum skull table.
Selective internal or external carotid angiography is advisable due to more clear pictures and less contrast is needed. Percutaneus cather technique (Seldinger method) is recommendable because it is very safe and avoidable of dissecting aneurism which rarely cause death. In vertebral angiography through femoral or brachial artery cather technique is advisable and direct puncture method is not often used.
As contrast, ditrizoate salts (urografin or hypaque) are the choice of contrast and 45~60%, 4-6 cc. is used. 60 cc. of contrast as maximum can be used in one examination. It is also advisable to check E.C.G. during cerebral angiography in order to protect heart accident.
Those facts are based upon author´s experiences of about more than 2,500 examinations at National Medical Center, Seoul, Korea.
