Intracranial stenosis as late sequela after cerebral radiation therapy for medulloblastoma is an exceptionally rare finding. We report for the first time a case of 31-year-old patient with a history of medulloblastoma 25 years ago and now presenting with radiation-induced high-grade basilar stenosis and recurrent ischemic symptoms despite best medical therapy. The stenosis was treated successfully with angioplasty followed by stenting using a self-expandable microstent. Additionally, MRI revealed multiple cavernomas, illustrating that radiation-induced microbleeds may occur.

Introduction: Blunt traumatic aortic injury (TAI) is a critical condition and a leading cause of mortality in trauma patients, often resulting from high-speed accidents. Thoracic endovascular aortic repair (TEVAR) has developed into the preferred therapeutic approach due to its minimally invasive nature and promising outcomes. This study evaluates the safety and efficacy of TEVAR for managing TAI over a 10-year period at a Level-1 trauma center.

Purpose: To propose a gastrointestinal bleeding management algorithm that incorporates an endoscopic and imaging scoring system and specifies management of vascular complication from button battery ingestion.
Recent Findings: Button batteries (BB) are found in many electronic devices and ingestions are associated with serious complications especially in cases of unwitnessed ingestions, prolonged impaction, and in children less than 5 years of age. Gastrointestinal bleeding from BB related vascular injury is rare but often rapidly fatal, with a mortality rate as high as 81%.
Sex and Cardiac Operations: Are We Being Fair to Our Female Patients?

Division of Cardiovascular Research, School of Medcine, University of Dundee, Ninewells Hospital, Dundee, UK. Electronic address:
Background: Research suggests that although men have a higher cardiovascular disease (CVD) rate, women with CVD are more likely to experience a poorer prognosis, possibly owing to incorrect diagnosis and poorer treatment. A question not yet addressed is whether some of this inequality could be due to sex bias when selecting patients for operation.
Method: The participants were from the Scottish Heart Health Extended Cohort who had been admitted to hospital with a cardiovascular diagnosis over the study period.

Basilar artery perforator aneurysms (BAPAs) are rare and may be occult on initial imaging due to their small size and susceptibility to intermittent thrombosis.1 2 Conventional treatments for aneurysms (eg, clipping or coiling) have proved challenging.3 Recently, endovascular electrocoagulation has been shown to be effective for BAPAs.
