To evaluate the incidence of mortality, hemorrhage, and neurological deficits in treating intracranial arteriovenous malformations (AVMs) in patients over 18 through a comparative analysis of surgical approaches and other therapeutic modalities. A systematic review was conducted using MEDLINE, Embase, CENTRAL, and LILACS databases in November 2023. Inclusion criteria included clinical trials, cohorts studies, case-controls studies, and case series comparing patients over 18 undergoing surgery or microsurgery versus other treatments (radiosurgery, isolated embolization, and conservative treatment).

Objective: Dural arteriovenous fistulas (DAVFs) with deep venous drainage (DVD) (DAVFs-DVD) are characteristically associated with non-hemorrhagic neurological deficits, most notably cognitive impairment. Large studies have yet to thoroughly characterize these DAVFs. We conducted an analysis of the largest cohort of DAVFs-DVD to provide a comprehensive characterization of this specific subset.

Background: The spinal arteriovenous malformations (sAVMs) have been challenging entities to diagnose and treat. The small structure, important function, and complex vascular anatomy of the spinal cord increase the difficulty of treating sAVMs.

Objective: The combining holistic and local perspectives in the diagnosis and treatment of sAVMs were provided to teach spinal vascular anatomy and AVMs.

Background And Purpose: Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent is a non-adhesive copolymer with specific features and endovascular behavior. This study assessed its safety and efficacy in a prospective real-life cohort.

Background: We aim to share our experience of transradial access (TRA) for cerebral angiography and intervention in five patients ranging from 6 days to 7 months of age.

Methods: In this institutional review board-approved, retrospective case series, we reviewed all patients who underwent TRA for cerebral angiography with and without intervention. We describe three techniques for radial artery cannulation, namely: (1) bareback; (2) with a micropuncture sheath; and (3) with an intravenous catheter.
