Retrospective cohort analysis reveals frequent arteriovenous shunting in middle meningeal artery after surgery for chronic subdural hematoma, indicating a need for further study.

Key Points

This study investigates the frequency and angiographic features of arteriovenous shunting in the middle meningeal artery after surgery for chronic subdural hematoma.
Retrospective analysis of patients who underwent MMA embolization after cSDH surgery from January 2020 to March 2023.
Consecutive patients were selected based on selective and superselective MMA angiography performed post-surgery.
Angiographic evidence of shunting, morphology, flow characteristics, and venous drainage were reviewed.
MMA arteriovenous shunting was identified in 11 out of 30 patients (36.7%).
Shunting occurred significantly more after craniotomy (90.9%) than burr-hole craniotomy (5.3%), p < 0.001.
All shunts exhibited low-flow characteristics and were absent on post-embolization control angiography.
