Role of CT angiography in guiding management decisions of newly diagnosed and residual arteriovenous malformations.

Overview

OBJECTIVE: Our aim was to show the usefulness of CT angiography for treatment planning of intracranial arteriovenous malformations. CONCLUSION: The conventional gold standard for analysis of these cerebrovascular lesions is digital subtraction angiography. Although this technique remains the gold standard, we have determined that CT angiography is a useful adjunct for characterization and stereotactic localization before surgical resection or radiosugical treatment of arteriovenous malformations. This multitechnique approach can lead to more accurate nidus localization and therefore more effective management strategies.
