Can blockage or sacrifice of the middle meningeal artery lead to hydrocephalus?
Child's Nervous System : ChNS : Official Journal of the International Society for Pediatric Neurosurgery 2016 November
BACKGROUND: The middle meningeal artery (MMA) is often sacrificed during neurosurgical procedures in the region of the pterion. This maneuver, herein, is hypothesized to be a potential reason for the development of postoperative hydrocephalus by injuring the vascular supply to the arachnoid granulations near the vertex of the skull, and thus disrupting their ability to allow for transfer of CSF from the subarachnoid space to the venous system.
MATERIALS AND METHODS: To test this theory, the middle meningeal artery was isolated at the skull base and injected with India ink. Next, the superior sagittal sinus was opened and the arachnoid granulations inspected.
RESULTS: All specimens demonstrated ink within the arachnoid granulations indicating that their blood supply is completely or at least partially via the middle meningeal artery. This finding with an illustrative case of surgical cautery of the middle meningeal artery at the skull base with subsequent development of hydrocephalus supports our hypothesis of potential role of iatrogenic MMA injury causing hydrocephalus.
CONCLUSIONS: Our cadaveric study shows that the blood supply of the arachnoid granulations of the superior sagittal sinus is via the middle meningeal artery. Additional cases of postoperative hydrocephalus following middle meningeal artery sacrifice are needed to support our hypothesis.
