Intraoperative digital subtraction neuroangiography: a diagnostic and therapeutic tool.

We report our experience with intraoperative digital subtraction neuroangiography to demonstrate its application as a diagnostic and therapeutic technique. Intraoperative neuroangiography was performed on 53 occasions in 43 patients using a portable imaging system. Thirty-two procedures were performed for diagnostic purposes after resection of arteriovenous malformations, clipping of aneurysms, or carotid endarterectomy. Unexpected problems were disclosed in seven cases and were surgically remedied immediately in four. In addition, angiography was used as a therapeutic tool in 21 cases to facilitate intraoperative embolization of a vascular lesion or to enable the angioplasty of a vessel inaccessible without direct surgical exposure. We found that by allowing a combined interventional neuroangiographic and neurosurgical approach, intraoperative angiography opened new avenues for treatment of intracranial vascular abnormalities.

Neurosurgical sonography: intraoperative and postoperative imaging of the brain.

Sonography was used to detect and localize intracranial lesions intraoperatively in 16 patients and to examine 31 patients (47 exams) postoperatively for a variety of clinical problems. Current sonographic technology was effective for localizing and differentiating cystic and solid intracranial pathology and for determining the size and boundaries of the intracranial lesions and their distance from the cortical surface. It was used occasionally as an aid for circumventing intracranial vessels during tissue dissection and, when used, determined the completeness of tumor dissection. Sonography also proved to be a reliable postoperative tool when surgically created cranial windows were present, but the location and size of the surgical window were critical to the quality of the images obtained. Both applications of this technique complement computed tomography and therefore can serve as a valuable adjunct in the treatment and follow-up of the neurosurgical patient.
