XXXX after removal of deep brain stimulation electrodes.

@entity1 @entity932 @entity86 @entity548
OBJECT: Many previous studies have shown that placement of deep brain stimulation (DBS) electrodes carries a considerable risk of @entity548 . To date, no studies have evaluated the incidence of @entity932 after removal of DBS electrodes. The authors performed a retrospective chart review to identify the incidence and trends in @entity548 after DBS electrode removal. METHODS: A retrospective chart review of all DBS electrodes removed at the Cleveland Clinic between October 2000 and May 2010 was performed. All @entity1 underwent postoperative CT scanning. Each @entity1 was evaluated for age, sex, side of placement, target, duration of lead placement, reason for removal, and medical comorbidities. RESULTS: A total of 78 lead removals were performed in the 10-year period (1300 leads were implanted during the same period). Of the 78 leads removed, 10 (12.8%) resulted in @entity548 seen on postoperative CT scans. The @entity548 were superficial cortical in 6 cases of lead removal (60%) and deep in 4 cases (40%). No statistically significant correlation to any of the factors evaluated was found. All @entity548 were asymptomatic. The authors' retrospective study of 78 DBS lead removals revealed a high risk of @entity932 (12.8% per lead). The risk of @entity548 during removal is significantly greater than the risk of @entity548 during implantation (2.0% per lead at the authors' center during the same period). There were more superficial @entity548 , and all @entity548 were asymptomatic. CONCLUSIONS: Removal of DBS leads carries a significantly higher risk of @entity86 that are seen on images but are not clinically symptomatic.
