Understanding postsurgical prescribing patterns and their impact on persistent opioid use is important for establishing reasonable opioid prescribing protocols. We aimed to determine national variation in postoperative opioid prescription practices following elective lumbar spine surgery and their impact on short-term refill prescriptions. ⋯ In analysis of filled opioid prescriptions, we observed a significant proportion of prescriptions >200 MMEs and wide regional variation in postdischarge opioid prescribing patterns following elective lumbar spine surgery.

Whether patients with minor traumatic intracranial hemorrhage (MTICH) require intensive care remains uncertain. This study aimed to identify the factors affecting the postinjury neurologic outcomes of patients with MTICH to determine optimal care. ⋯ MTICH rarely resulted in permanent morbidity and mortality. Older patients exhibited higher incidences of MTICH and were at a higher risk for unfavorable outcomes.

Congenital hypoplasia or aplasia of the A1 segment of the anterior cerebral artery is associated with an increased incidence of berry aneurysms at the anterior communicating artery (ACoA) complex. We analyzed the factors contributing to ACoA aneurysm rupture. ⋯ ACoA aneurysms are small (<5 mm) and have a high risk of rupture. A1 segment hypoplasia or aplasia is a risk factor for ACoA aneurysm formation; however, it was uncorrelated with aneurysm diameter or rupture risk. The strongest independent risk factors for rupture were age <65 years and aneurysm diameter.

Hospital length of stay (LOS) is an important cost driver in neurosurgery. Broader surgical literature has shown that patient-related factors, including comorbidities, and procedure-related factors, such surgeon experience, may be associated with LOS. Because value optimization strategies may be targeted toward either domain, this study investigated the contributions of patient-related and procedure-related factors in predicting prolonged intensive care unit LOS (iLOS) and total hospital LOS (tLOS). ⋯ Patient-specific factors are the main drivers of prolonged iLOS and tLOS among patients with brain tumor. Frailty was significantly associated with both iLOS and tLOS on multivariate analysis. Efforts to improve care value should focus on strategies to optimize patient status, such as prehabilitation and enhanced recovery after surgery.

Enterprise stents are widely used for intracranial aneurysms located on small arteries (<2.5 mm in diameter) and change the geometry of parent arteries. The purpose of this study was to investigate the correlation between vascular geometry changes and long-term outcomes. ⋯ Enterprise stent-assisted coiling of intracranial aneurysms located on small arteries is safe and effective. Our study found that Enterprise deployment in small arteries had a low procedural complication rate and high stent tolerance. Vascular geometry changes play an important role in aneurysm recanalization.
