Temporal Base Transdural Anastomosis in Moyamoya Disease: A Potential Association with Posterior Cerebral Artery Involvement and Clinical Importance.

ABSTRACT: Moyamoya disease is associated with the formation of collateral pathways, including transdural anastomosis, such as vault and ethmoidal moyamoya. However, temporal base transdural anastomosis remains unrecognized. This study investigates the imaging characteristics and features of temporal base transdural anastomosis in moyamoya disease. This retrospective review was conducted on 164 hemispheres from 82 patients with moyamoya disease admitted to our institution between 2012 and 2024. Digital subtraction angiography helped identify temporal base transdural anastomosis, which is classified as "obvious" or "faint" types based on digital subtraction angiography findings. Affected hemispheres and patients were grouped based on the presence or absence of temporal base transdural anastomosis, and
