RESUMEN
BACKGROUND: The postoperative outcomes and the predictors of seizure control are poorly studied for supratentorial cavernous angiomas (CA) within or close to the eloquent brain area. OBJECTIVE: To assess the predictors of preoperative seizure control, postoperative seizure control, and postoperative ability to work, and the safety of the surgery. METHODS: Multicenter international retrospective cohort analysis of adult patients benefitting from a functional-based surgical resection with intraoperative functional brain mapping for a supratentorial CA within or close to eloquent brain areas. RESULTS: A total of 109 patients (66.1% women; mean age 38.4 ± 12.5 yr), were studied. Age >38 yr (odds ratio [OR], 7.33; 95% confidence interval [CI], 1.53-35.19; P = .013) and time to surgery > 12 mo (OR, 18.21; 95% CI, 1.11-296.55; P = .042) are independent predictors of uncontrolled seizures at the time of surgery. Focal deficit (OR, 10.25; 95% CI, 3.16-33.28; P < .001) is an independent predictor of inability to work at the time of surgery. History of epileptic seizures at the time of surgery (OR, 7.61; 95% CI, 1.67-85.42; P = .003) and partial resection of the CA and/or of the hemosiderin rim (OR, 12.02; 95% CI, 3.01-48.13; P < .001) are independent predictors of uncontrolled seizures postoperatively. Inability to work at the time of surgery (OR, 19.54; 95% CI, 1.90-425.48; P = .050), Karnofsky Performance Status ≤ 70 (OR, 51.20; 95% CI, 1.20-2175.37; P = .039), uncontrolled seizures postoperatively (OR, 105.33; 95% CI, 4.32-2566.27; P = .004), and worsening of cognitive functions postoperatively (OR, 13.71; 95% CI, 1.06-176.66; P = .045) are independent predictors of inability to work postoperatively. CONCLUSION: The functional-based resection using intraoperative functional brain mapping allows safe resection of CA and the peripheral hemosiderin rim located within or close to eloquent brain areas.

Long-term impact of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on health-related quality of life (HRQOL) and associated factors in patients with Parkinson's disease (PD) are not clear. In this prospective study, we included 69 PD patients (64 % men, mean age 61.3 ± 7.4 and disease duration 13.2 ± 5.7 years) undergoing STN-DBS. They were evaluated preoperatively (baseline), 1 and 5 years postoperatively assessing 39-item Parkinson's Disease Questionnaire (PDQ-39), Schwab and England Activities of Daily Living Scale (SEADL), Unified Parkinson's Disease Rating Scale (UPDRS) off- and on-medication, patient diaries, dopaminergic treatment, mortality and surgical complications. Five years postoperatively, off-medication, there were improvements from baseline in UPDRS-II and III total (27.2 and 26.7 %, respectively) and SEADL (18.6 % more completely independent patients) (p < 0.05) scores, while on-medication, there was a deterioration in UPDRS-III (37.8 %, mainly axial signs) (p < 0.05) and minor improvements in SEADL (3.7 %). While at 1 year PDQ-39, the summary index improved substantially (36.5 %) (p < 0.05), at 5 years patients regressed (only 8.8 %) (p < 0.05), though changes in PDQ-39 subscores remained significant, with improvements in ADL (18.8 %), emotional well-being (19.0 %), stigma (36.4 %) and discomfort (20.6 %), despite worsening in communication (47.8 %) (p < 0.05). Lower preoperative PDQ-39 summary index and greater 1-year UPDRS-III-off total score gain predicted better long-term HRQOL. STN-DBS produces long-term improvements in HRQOL in PD. Preoperative HRQOL and short-term postoperative changes in off-medication motor status may predict long-term HRQOL in PD following STN-DBS.
