Özet

BACKGROUND: In this prospective study, the use of a system of ultrasound-integrated neuronavigation was investigated to evaluate the benefits of improving brain shift during cerebral cavernous angioma (CCA) resection. METHODS: Between June 2000 and June 2005, 26 CCAs of 22 patients underwent microsurgical removal with the guidance of neuronavigation, and a 7-MHz intraoperative ultrasonography (Toshiba, Tosbee SSA 240 A, Tokyo, Japan) at our institution. The preoperative neurologic status and postoperative outcome were recorded. Patients' follow-up monitoring ranged from 6 months to 4 years (mean, 18 mo). RESULTS: The computer neuronavigation-calculated registration accuracy ranged between 0.2 and 1.7 mm (mean, 0.5 mm). During resection, brain shift was measured 2 to 4.5 mm (mean, 3.2 mm) in 14 lesions, as verified by neuronavigation. The overall postoperative neurologic outcome was excellent in 21 of the 22 (95.4%) patients. Postoperative magnetic resonance imaging was performed in all cases and showed a total resection of the lesion in 21 patients (95.6%). The resection was subtotal in 1 patient (4.4%). Although there was no mortality, 2 patients (9.1%) had worsening in neurologic status in early postoperative period. CONCLUSIONS: On the basis of these results, a system of intraopeative ultrasound-integrated neuronavigation is a less expensive and time consuming imaging technique for the surgical treatment of CCAs. The update of a neuronavigation system with both intraoperative ultrasound reliably correct of the brain shift and is reliable intraoperative guidance tool in localization of deep-seated CCAs because it operates in real time. © 2009 Lippincott Williams & Wilkins, Inc.
