The surgical evacuation, including stereotactic aspiration, endoscopic evacuation, and craniotomy, is the most effective way to reduce the volume of intracerebral hemorrhage. However, credible evidence for the effects of these techniques is still insufficient. The present study explored the long-term outcomes of these techniques in the treatment of basal ganglia hematoma with low Glasgow Coma Scale (GCS) scores (≤8) and large-volume (≥40 ml), which were predictors of high mortality. Methods: Two hundred and fifty-eight consecutive patients were reviewed retrospectively. The primary and secondary outcomes were 6-months mortality and 6-months modified Rankin Scale score, which were assessed by a multivariate logistic regression model. Results: Compared with the endoscopic evacuation group, the mortality was significantly higher in the stereotactic aspiration group (OR 6.858, 95% CI 3.146-14.953) and open craniotomy group (OR 3.315, 95% CI 1.497-7.341). Age (OR = 2.237, 95% CI 1.290-3.877) and herniation (OR = 2.257, 95% CI 1.172-4.348) were independent predictors for mortality. No significant difference in the neurological functional outcome was found in the stereotactic aspiration group (OR 0.501, 95% CI 0.192-1.308) and the craniotomy group (OR 0.774, 95% CI 0.257-2.335) compared with the endoscopic evacuation group. Conclusion: Endoscopic evacuation significantly decreased the 6-months mortality in patients with hemorrhage ≥40 ml and GCS ≤ 8.
Study Design. A retrospective analysis. Objective. To evaluate whether the rotation of the presumed lower instrumented vertebra (LIV) on baseline convex side-bending (SB) radiographs leads to distal adding-on in Lenke 5C adolescent idiopathic scoliosis (AIS) patients. Summary of Background Data. In Lenke 1A patients, derotation of the presumed LIV on baseline bending films is important owing to the association between LIV rotation and postoperative distal adding-on. However, the relationship between distal adding-on and derotation of the presumed LIV in Lenke 5C patients remains unknown. Methods. Eighty-five Lenke 5C patients with a minimum of 2-year follow-up for posterior fusion were enrolled. L3 was selected as the LIV in all patients. Patients were divided into the presumed LIV derotation (DR group) and nonderotation (NDR group) groups according to derotation of the presumed LIV on SB films. Radiographic parameters, including Cobb angle, coronal balance, lower disc angle of LIV, LIV tilt, and LIV translation, were measured pre- and postoperatively. Results. Distal adding-on occurred in 16 patients (18.8%) at the final follow-up: 2 patients (10%) in the DR group and 14 patients (21.5%) in the NDR group (P = 0.248). Distal adding-on incidence was not greatly reduced with derotation of the presumed LIV on SB films at baseline. In the NDR group, the immediately postoperative lower disc angle of the LIV, LIV tilt, and LIV translation were significantly smaller in patients without than in those with distal adding-on (all P < 0.05). Logistic regression analysis revealed that the immediately postoperative LIV tilt and LIV translation were significant predictors of distal adding-on. Conclusion. Derotation of the presumed LIV on SB films may hint less risk of distal adding-on in Lenke 5C patients. Nevertheless, horizontalization of the LIV and minimizing LIV translation during correction could reduce the risk of distal adding-on despite the presence of LIV rotation at baseline.
