National Resident Matching Program Performance Among US MD and DO Seniors in the Early Single Accreditation Graduate Medical Education Era.

Introduction: As of the 2020 National Resident Matching Program (NRMP), nearly all applicants are evaluated together for graduate medical education (GME) candidacy. We set out to characterize US MD and DO Senior residency match performance in the single-accreditation GME era.

Methods: A retrospective study was conducted in 2021 utilizing data collected from the 2018 and 2020 NRMP Charting Outcomes in the Match publications aggregated and subdivided into three groups based on competitiveness: low (LC), moderate (MC), and high (HC).

Simultaneous Treatment of Petroclival Meningiomas and the Trigeminal Nerve with Gamma Knife Radiosurgery for Tumor-Related Trigeminal Neuralgia.

Background: Some petroclival meningiomas cause trigeminal nerve compression, leading to disabling trigeminal neuralgia (TN). Tumor resection and nerve decompression can offer pain relief but might not be feasible in all patients. Simultaneous stereotactic radiosurgery (SRS) to the tumor and nerve is another option.

DynaCT Enhancement of Subdural Membranes After Middle Meningeal Artery Embolization: Insights into Pathophysiology.

Objective: Middle meningeal artery (MMA) embolization could be an effective method of inhibiting neovascularization of the subdural capsular membrane and preventing hematoma maintenance. We sought to better understand how the MMA might affect subdural hematoma physiology and how this process might be modified by embolization.

Methods: We performed a retrospective review of 27 patients with 29 subdural hematomas (SDHs) who had undergone MMA embolization from July 2018 to May 2019.

Black Bone Disease of the Skull.

We present an image of a patient's skull characterized by dark, irregular discoloration. This was discovered incidentally in a 66-year-old man who underwent craniotomy for resection of a glioblastoma. This image demonstrates cranial black bone disease.

Intrareservoir Administration of Alteplase to Treat a Distal Ventriculoatrial Shunt Obstruction.

Background: Ventriculoatrial shunts can be afflicted with distal malfunctions due to thrombus formation at the distal tip. Distal tip thrombus formation may occur more commonly in oncologic patients who are predisposed to hypercoagulability.

Case Description: A patient who had a ventriculoatrial shunt placed for leptomeningeal carcinomatosis presented with headaches and confusion and was found to have a partial distal shunt obstruction.

Endovascular and Microsurgical Aneurysm Training in a Chicken Thigh and Leg Pulsatile Model.

Background: Neurovascular training models include animal models, synthetics, or computer simulation. In vivo models are expensive and require significant resources. Synthetic/computer models do not reflect the elasticity of fresh vessels.
