Utilization of the emergency department (ED) is associated with medical and social comorbidities. These factors may also be associated with medical complications after complex surgeries. This study investigated how pre-operative ED use increases risk of posterior lumbar interbody fusion (PLIF) complications. ⋯ Patients with any pre-operative ED visit had an increased risk for post-operative ED use, readmission, and medical complications. The risk difference increased with each additional pre-operative visit. Patient counseling and protocols that reduce preventable ED visit in the pre-operative period may reduce a patient's risk for costly post-operative complications.

Glioblastomas contacting the subventricular zone (SVZ) are associated with poor prognosis, and the impact of ventricular entry (VE) during resection remains controversial. Since glioblastomas with SVZ involvement often require VE, both SVZ involvement and VE are confounding factors. This study aimed to evaluate the effect of VE during glioblastoma resection by comparing patients with and without SVZ involvement. ⋯ VE during glioblastoma resection does not impact complications or nonlocal recurrence. Surgeons may safely perform VE during resection of both SVZ and non-SVZ glioblastomas without adverse effects.

This study was to explore the factors associated with prolonged hospital length of stay (LOS) in patients with intracranial aneurysms (IAs) undergoing endovascular interventional embolization and construct prediction model machine learning algorithms. ⋯ This study comprehensively identified key predictive factors for prolonged LOS in patients with IA undergoing interventional embolization and confirmed the efficacy of an RF model for predicting prolonged LOS in patients with IA undergoing interventional embolization. The construction of the LOS prediction model may effectively optimize healthcare resource utilization, inform better clinical decision-making, and offer valuable prognostic insights.

Side-to-side microvascular anastomosis is the most difficult type of anastomosis. The best way to master microvascular anastomosis technique is deliberate practice in the microsurgical laboratory. ⋯ Three types of side-to-side microvascular anastomosis training models using abdominal vessels could be used to mimic different microvascular anastomotic situations.

Surgical treatments for degenerative lumbar spinal disorders involve decompression of neural structures and arthrodesis to address pain from unstable intervertebral segments. Lumbar instrumented facet fusion (IFF), a less invasive technique, has shown positive short-term outcomes, but reports on its long-term outcomes are scarce. This study aims to report its long-term biomechanical stability and clinical outcomes. ⋯ Instrumented facet fusion is a safe and less invasive alternative method of lumbar spinal arthrodesis with comparable fusion rate and clinical outcome. This method show relatively low revision rate.
