White Sox pitcher Danny Farquhar survived a ruptured brain aneurysm; Congress can improve odds for others
Brain aneurysms, weak spots in the arteries that supply blood to the brain, can burst without warning, causing significant brain damage, life-altering disabilities and death. Lawmakers should pass “Ellie’s Law” to aid critical research to prevent fatalities and improve quality of life for survivors.

The neurosurgical marriage: evaluating the interplay of work life and home life from the perspective of partners of neurosurgical residents
Burnout and work-life balance have been noted to be problems for residents across all fields of medicine, including neurosurgery. No studies to date have evaluated how these factors may contribute to issues outside of the hospital, specifically residents’ home lives. This study aimed to evaluate the interplay between home life and work life of neurosurgical residents, specifically from the point of view of residents’ significant others.

Safety and efficacy of the Pipeline Flex embolization device with Shield Technology for the acute treatment of ruptured internal carotid artery pseudoaneurysms: a multi-institution case series
Ruptured blister, dissecting, and iatrogenic pseudoaneurysms are rare pathologies that pose significant challenges from a treatment standpoint. Endovascular treatment via flow diversion represents an increasingly popular option; however, drawbacks include the requirement for dual antiplatelet therapy and the potential for thromboembolic complications, particularly acute complications in the ruptured setting. The Pipeline Flex embolization device with Shield Technology (PED-Shield) offers reduced material thrombogenicity, which may aid in the treatment of ruptured internal carotid artery pseudoaneurysms.
RESEARCH
Is a picture-perfect thrombectomy necessary in acute ischemic stroke?
The benefit of complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 3) over near-complete reperfusion (≥90%, mTICI 2c) remains unclear. The goal of this study is to compare clinical outcomes between mechanical thrombectomy (MT)-treated stroke patients with mTICI 2c versus 3.
RESEARCH
Urgent Treatment for Symptomatic Carotid Stenosis: The Pittsburgh Revascularization and Treatment Emergently After Stroke (PIRATES) Protocol
To analyze prospectively recorded data from an institutional protocol that standardized the urgent (<48 h) treatment of patients presenting with symptomatic carotid stenosis and underwent either carotid stenting (CAS) or carotid endarterectomy (CEA).

Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2)
CREST2 is an international trial studying the outcomes of medical management versus surgical intervention for carotid stenosis (narrowing of the carotid artery). Patients who have carotid stenosis and who have not had a stroke because of it may qualify for the study.
