- Neuroradiology Fellowship Requirements: Updates in 2019
Notable changes made since the prior requirements were last revised in 2007 primarily affect the number of required procedures, the academic support defined for the program director, and modifications to the curriculum. The new requirements allow fellows to fulfill the foundational expectations for the neuroradiology fellowship and encourage programs to maintain some flexibility to teach individual specialty areas of clinical excellence.
- Artery of Davidoff and Schechter Supply in Dural Arteriovenous Fistulas
The artery of Davidoff and Schechter is a dural branch of the posterior cerebral artery that can supply the meninges close to the falcotentorial junction. It is usually not identified on angiography except when enlarged in the setting of a dural AVF or meningioma. The impact on treatment of the artery of Davidoff and Schechter supply to a fistula is not well-described in the literature. The authors' retrospective analysis of patients with dural AVFs treated at the Toronto Western Hospital between 2006 and 2018 identified 6 patients with dural AVFs receiving supply from the artery of Davidoff and Schechter (of a total of 173 patients with dural AVFs). All patients were initially treated by transarterial embolization using liquid embolic agents. Three patients required a second endovascular procedure partly due to residual supply from the artery of Davidoff and Schechter.
