As corrective surgery for cervical deformity (CD) increases, so does the rate of complications and reoperations. To minimize suboptimal postoperative outcomes, it is important to develop a tool that allows for proper preoperative risk stratification. ⋯ Revisions were predicted using a predominance of radiographic parameters while the occurrence of major complications relied on baseline bone health, radiographic, and surgical characteristics.

Knowledge about the natural course of brain arteriovenous malformations (AVMs) have increased during the past 20 years, as has the number of AVMs treated, especially larger ones. It is thus timely to again analyze the risk for hemorrhage after Gamma Knife Surgery (GKS). ⋯ Large AVMs (>5 cm 3 ) treated with low doses (≤16 Gy) had higher and small AVMs treated with high doses a lower risk for hemorrhage as compared with untreated AVMs. This was detectable within the first 6 months after GKS. No difference in hemorrhage rate could be detected for the other AVMs. Based on our findings, it is advisable to prescribe >16 Gy to larger AVMs, assuming that the risk for radiation-induced complications can be kept at an acceptable level.

Nationwide Readmission Rates and Hospital Charges for Patients With Surgical Evacuation of Nontraumatic Subdural Hematomas: Part 2-Burr Hole Craniostomy.
Nontraumatic subdural hematoma (SDH) is a common neurological disease that causes extensive morbidity and mortality. Craniotomy or burr hole craniostomy (BHC) is indicated for symptomatic lesions, but both are associated with high recurrence rates. Although extensive research exists on postoperative complications after BHCs, few studies have examined the underlying causes and predictors of unplanned 30-day hospital readmissions at the national level. ⋯ These national trends in 30-day readmission rates after nontraumatic SDH evacuation by BHC not otherwise published provide quality benchmarks that can aid national quality improvement efforts.

The first-pass effect in endovascular thrombectomy (EVT) has been associated with better clinical outcomes and decreased stroke progression in large vessel occlusion but has not been evaluated in distal, medium vessel occlusions (DMVOs). ⋯ The mFPE may be associated with better clinical outcomes and lower stroke progression in DMVO.
