Abstract

OBJECTIVE:

In presurgical planning for intracranial meningiomas, the relationship between tumors and adjacent vasculature must be identified. The purpose of this study was to evaluate the usefulness of 3-dimensional digital subtraction angiography (3D-DSA) with dual-volume visualization (DVV).

METHODS:

Between February 2013 and April 2016, 26 patients with intracranial meningiomas enrolled in this study. Two or 3 days before surgery, 3D-DSA with DVV was performed for presurgical planning. If necessary, the tumor was simultaneously embolized.

RESULTS:

Vascular supply and disfiguration observed by preoperative 3D-DSA with DVV closely resembled those actually observed during surgery. All but 2 patients had total tumor resection (Simpson grade 1 or 2). Three of 26 patients had new neurologic deficits.

CONCLUSIONS:

3D-DSA with DVV may be useful for preoperative planning by allowing the surgeon to identify the relationship between a tumor and peritumoral vasculature before meningioma surgery. Young neurosurgeons with little experience may benefit most from this technique.
