To establish and validate a risk prediction model for perioperative ischemic complication (PIC) of endovascular treatment for ruptured anterior communicating artery aneurysms (ACoAAs). ⋯ A history of hypertension, high preoperative Fisher grade, complete A1 conformation, use of stent-assisted coiling, and aneurysm orientation (pointing upward) are risk factors for PIC for ruptured ACoAAs. This novel nomogram might serve as a potential early warning sign of PIC for ruptured ACoAAs.

In most cases of trigeminal neuralgia (TN), the trigeminal nerve is compressed by the arterial vasculature. We sought to address the gap in understanding of pain outcomes in patients with sole arterial versus sole venous compression. ⋯ Patients with TN with sole venous compression show worse pain outcomes after microvascular decompression compared with those with only arterial compression.

Historically, depressed skull fractures that warranted surgery were treated in 2 stages: the first stage involved debridement and craniectomy, followed by the second stage of delayed cranioplasty. More recently, single-stage autologous cranioplasty has been proven to be safe. However, there is a paucity of literature regarding single-stage titanium mesh cranioplasty when autologous repair is not possible. ⋯ Autologous cranioplasty for depressed skull fractures is not always possible especially in cases of significant comminution. From our case series, single-stage titanium mesh cranioplasty appears to be a safe option.

This study aimed to examine whether preoperative severity and location of lumbar intervertebral disc vacuum phenomenon (VP) influence surgical outcomes after single-level transforaminal lumbar interbody fusion. ⋯ Preoperative SVP at fused disc is not associated with surgical outcomes; however, SVP at nonfused discs is correlated with clinical outcomes.

To determine the effectiveness of the unsubtracted roadmap technique (USRT) for decreasing cement leakage (CL) during percutaneous vertebroplasty (PVP). ⋯ USRT is an effective method for reducing CL and radiation exposure during PVP.
