Intracranial arteriovenous malformation. Contralateral steal phenomena

Journal Article:

Abstract

Sixty-two patients with radiographically proven intracranial arteriovenous malformations underwent preoperative regional cerebral blood flow measurement with {sup 133}Xe signal-photon emission computed tomography. Contralateral regions of hypoperfusion were deteceted in all cases. Steal severity was assessed according to the contralateral steal index (ISteal(c)). ISteal(c) was < 0.7 (severe) in 22 (35%), 0.7-0.8 (intermediate) in 18 (29%), and > 0.8 (mild) in 22 (35%). ISteal(c) was more frequently severe or mild in females and more often intermediate in males in males (p < 0.05). Hyperemic complications were encountered more frequently in patients with intermediate ISteal(c) (p = 0.086). An unfavorable outcome was associated with less severe contralateral steal (p = 0.12). A detailed clinical, radiographic, and hemodynamic profile may help to preperatively identify patients at high risk for a poor surgical outcome. (author).
