The objective of this study was to determine if Medicare status and age affect clinical outcomes following anterior cervical discectomy and fusion. ⋯ Regardless of age and Medicare status, all patients undergoing cervical discectomy and fusion had significant clinical improvement postoperatively. However, Medicare patients under age 65 have a smaller magnitude of improvement in PROMs.

This study aimed to identify the risk factors for acute obstructive hydrocephalus (AOHCP) after extra-axial cerebellopontine angle (CPA) tumor surgery using the retrosigmoid (RS) approach. ⋯ An increased risk of AOHCP after the RS approach was observed in patients with extra-axial CPA tumors with clival extension and major fourth ventricle compression. Compulsive and meticulous hemostasis must be achieved because postoperative hemorrhage is associated with AOHCP.

The effect of prolonged symptom duration in patients undergoing ambulatory MIS-TLIF on postoperative clinical outcomes has not been well studied. We aim to compare symptom duration of pain and/or weakness on postoperative outcomes in patients undergoing outpatient MIS-TLIF. ⋯ Independent of symptom duration, patients reported significant improvement in back pain at all postoperative periods. Patients presenting with shorter symptom duration consistently reported significant improvement in leg pain postoperatively. Patients with shorter symptom duration demonstrated greater MCID achievement in back and leg pain. Patients indicated for outpatient MIS-TLIF may benefit more from earlier intervention following onset of symptoms.

Angiographic treatment of asymptomatic cerebral vasospasm (CVS) in aneurysmal subarachnoid hemorrhage remains controversial. We sought to investigate its relationship with the development of delayed cerebral ischemia. ⋯ Cerebral angiography has a low rate of detecting moderate-severe CVS in asymptomatic patients. Moreover, there was no statistically significant difference in the rate of delayed cerebral ischemia between asymptomatic patients treated versus those not treated for CVS. There was significant association between the severity of CVS and the intensive care unit and hospital length of stay. More studies are needed to evaluate the utility of treating asymptomatic CVS in high-grade aneurysmal subarachnoid hemorrhage.

Patients with nmoyamoya disease (MMD) who present primarily with ischemic stroke are known to have greater rates of perioperative strokes as compared with those who present with nonstroke symptoms. The optimal timing for revascularization for these patients remains unclear. ⋯ Patients with MMD who present with ischemic stroke are more likely to have perioperative strokes, overall perioperative complications, worse long-term mortality rates, and lower rates of stroke-free survival if revascularization surgery occurred within 90 days of last stroke.
