脳血管性病変におけるステレオDSAの臨床的評価

Seventy-one series of stereoscopic DSA utilized on thirty-nine patients with intracranial vascular lesions were evaluated by comparison with subtracted magnified angiograms or independently. All stereoscopic series had good or fairly good stereoscopic quality. Stereoscopic DSA was useful in the preoperative stereoscopic vascular analysis of vascular lesions such as aneurysms, arteriovenous malformations, cartotid-cavernous fistulas, obstructive or stenotic vascular lesions and vascular elongations. Stereoscopic DSA was also useful for evaluation of the post-operative or post-embolization states of these vascular lesions. We think that stereoscopic DSA can replace many areas of conventional angiography for vascular lesions in the near future.
