Abstract

Introduction

Middle meningeal artery embolization (MMAe) is a minimally-invasive approach for the treatment of subdural hematomas (SDH). Small vessel caliber and ectopic origin of the middle meningeal artery (MMA) may lead to unsuccessful embolization and/or serious morbidity. Thus, use of an objective scale to pre-procedurally assess candidacy for MMA embolization is an essential component of operative planning.

Methods

A retrospective analysis of all patients having undergone MMAe across 4 years at a single institution was performed.

Results

169 MMAe procedures were performed for SDH, of which 3 were found to have a foramen spinosum diameter, termed the “Spinosum Roentgen Index” (SRI), measuring <2 mm on pre-procedure non-contrast CT Head. A statistically-significant correlation was found between foramen spinosum diameter <2 mm and unsuccessful embolization.

Conclusion

Assessment of foramen spinosum diameter (Spinosum Roentgen Index (SRI)) may increase suspicion for aberrant MMA anatomy when measuring <2 mm, which can serve as valuable data in assessing risk versus benefit of MMA embolization, and ultimately minimize unexpected intraprocedural or immediate postprocedural complications.

期刊介绍： The mission of Clinical Imaging is to publish, in a timely manner, the very best radiology research from the United States and around the world with special attention to the impact of medical imaging on patient care. The journal''s publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. Papers are carefully peer-reviewed and selected by our experienced subject editors who are leading experts spanning the range of imaging sub-specialties, which include: -Body Imaging- Breast Imaging- Cardiothoracic Imaging- Imaging Physics and Informatics- Molecular Imaging and Nuclear Medicine- Musculoskeletal and Emergency Imaging- Neuroradiology- Practice, Policy & Education- Pediatric Imaging- Vascular and Interventional Radiology
