Middle Meningeal Artery (MMA) Embolization Compared to Traditional Surgical Strategies to Treat Chronic Subdural Hematomas (cSDH)

September 17, 2019 updated by: Ronald Benitez, MD, Atlantic Health System

Pilot Study to Evaluate Safety of and Efficacy of Middle Meningeal Artery (MMA) Embolization Compared to Traditional Surgical Strategies to Treat Chronic Subdural Hematomas (cSDH)

Chronic Subdural Hematoma (cSDH) is a common hematologic problem particularly in older patients. The purpose of this study is to evaluate the safety and efficacy of middle meningeal artery (MMA) embolization compared to traditional surgical strategies for patients presenting with chronic subdural hematoma (cSDH). Although MMA embolization is minimally-invasive procedure that is routinely used for the treatment of tumors or vascular formations (1), this study investigates the use of an established procedure for a new disease state.

Study Overview

Detailed Description

The purpose of the research study is to evaluate the safety and efficacy of a new, less-invasive procedure to treat chronic subdural hematoma (cSDH). A subdural hematoma occurs when blood collects on the brain's surface beneath the skull. Subdural hematomas can be life-threatening. They usually result from a head injury. This study will compare the new procedure to conventional surgical treatment of chronic subdural hematoma (cSDH). The new procedure is called middle meningeal artery embolization (MMA).

Current or conventional treatment of chronic subdural hematoma (cSDH) involves surgery (burr hole drainage and craniotomy) to access and remove the cause of the bleeding that is causing the subdural hematoma.

The new procedure, MMA embolization, involves guiding a catheter that is inserted into a blood vessel to the area of the brain that is supplying blood to the subdural hematoma. Particles or a special type of glue will be released to stop the bleeding that is causing the subdural hematoma. This technique has been used to treat other brain conditions, for example, (to treat tumors or malformation of blood vessels).
