Comparative Study
Early vs. Delayed Surgical Management of Ruptured Arteriovenous Brain Malformations in a Tertiary Referral Center in Colombia, South America.
Surgical timing after rupture of brain arteriovenous malformations (AVMs) is controversial. There is scarce literature on AVM surgical outcomes from developing countries. This study aims to determine if there is a difference between early and delayed surgical resection for patients with ruptured brain AVMs. ⋯ In this case series of 31 patients from a developing country, there were no differences in clinical outcomes at the final follow-up between acute and delayed surgical interventions for ruptured AVMs. The most important factor associated with the final outcomes was the initial Glasgow Coma Scale.

The aim of this study is to evaluate the efficacy of cerebral revascularization for Moyamoya disease (MMD) with extracranial internal carotid artery occlusion (ICAO). ⋯ Cerebral revascularization can prevent recurrent ischemic and hemorrhagic stroke events for MMD patients with extracranial ICAO. There was no difference on long-term clinical outcomes after combined bypass, direct bypass, and indirect bypass surgery. The cerebral revascularization has similar effect on the MMD patients with extracranial ICAO and MMD patients without extracranial ICAO.

This study aimed to evaluate preoperative and perioperative predictors associated with persistent low back pain (LBP) following lumbar fusion in patients aged >75 years. ⋯ This study showed that a relatively younger age, history of preoperative lumbar decompression, and greater preoperative VAS score for LBP were preoperative predictors of postoperative persistent LBP following lumbar fusion in elderly patients. In contrast, preoperative spinopelvic sagittal parameters were not associated with persistent postoperative LBP. Although lumbar fusion is expected to improve LBP, surgeons should pay attention to age, surgical history, and preoperative back pain intensity.

To evaluate the short-term surgical outcomes and the reimbursement patterns, after treatment of type 2 odontoid fractures using the anterior or posterior approach. ⋯ In this matched analysis, the anterior approach for type 2 odontoid fractures was superior to the posterior approach. The anterior approach was associated with significantly shorter operation times, hospital stays, fewer transfusions, nonroutine discharges, and higher reimbursements.

Endoscopic management of pediatric hydrocephalus is always challenging because of the different anatomical structure of the ventricles. The aim of this study is to document the endoscopic anatomy of the ventricular system and to show the variations and deformations. ⋯ The compliance of the brain deteriorates with increasing intracranial pressure in pediatric hydrocephalus and the intraventricular anatomical structures differ from the normal anatomy. Developmental anomalies of the ventricle are also significant and since all these variations are often unpredictable on preoperative imaging, awareness of endoscopic anatomy, variations, and deformations will improve operative safety in children.
