Intraoperative digital subtraction angiography: a review of 112 consecutive examinations.

摘要: PURPOSE To examine the effect of intraoperative angiography on neurosurgery and angiographic technical success, safety, accuracy. METHODS Angiographic studies, surgical reports, hospital records were reviewed retrospectively for 112 consecutive procedures in which was performed during neurosurgery. The results conventional postoperative angiograms 28 also reviewed. A portable digital subtraction unit used all patients. Decisions operating room based review stored videotaped images. RESULTS Eighteen studies obtained 14 patients after arteriovenous malformation resection. Unsuspected residual nidus identified resected 3 angiogram altered therapy 2 undergoing staged resections malformations. Sixty-six aneurysm clipping, with clinically significant changes made 5 Of examinations carotid endarterectomy, led to revision. Two complications occurred.
