Effect of Prior Embolization on Outcomes After Stereotactic Radiosurgery for Pediatric Brain Arteriovenous Malformations: An International Multicenter Study.
Pediatric brain arteriovenous malformations (AVMs) are a significant cause of morbidity but the role of multimodal therapy in the treatment of these lesions is not well understood. ⋯ Embolization appears to decrease cumulative obliteration rates after SRS for pediatric AVMs without affecting the risk of post-treatment hemorrhage or adverse radiation effects arguing against the routine use of pre-SRS embolization. While endovascular therapy can be considered for occlusion of high-risk angioarchitectural features prior to SRS, future studies are necessary to clarify its role.

Historical Article
First Female Neurosurgeon in the United States: Dorothy Klenke Nash, MD.
Dr Dorothy Klenke Nash (1898-1976) became the first female neurosurgeon in the United States in 1928 and maintained her status as the country's only female neurosurgeon until 1960. She graduated with her medical degree from the Columbia College of Physicians and Surgeons in 1927 and then trained at the Neurologic Institute of New York under Dr Byron Stookey. During her training, she contributed to the advancement of neurosurgical practice through academic research. ⋯ She retired from neurosurgical practice in 1965, at which time she devoted herself to her grandchildren and her Catholic faith. She died on March 5, 1976 at the age of 77. With unwavering tenacity, Dr Nash paved the way for all women in neurosurgery.

The relationship between trans-stenotic blood flow velocity differences and the cerebral venous pressure gradient (CVPG) in transverse sinus (TS) stenosis (TSS) has not been studied. ⋯ The trans-stenotic blood flow velocity difference significantly correlates with the CVPG in TSS. As a noninvasive imaging modality, 4D flow MRI may be a suitable screening or complimentary tool to decide which TSS may benefit from invasive venous manometry.
