Minimally Invasive Approach to Subdural Hematoma Treatment Using IRRAflow Catheter and Middle Meningeal Artery Embolization

Abstract

Chronic subdural hematoma (cSDH) is a common neurosurgical pathology that usually occurs in the seventh decade of life. Patients can present with mental status changes, focal neurologic deficits, seizures, headaches, or may be asymptomatic. Recurrence is common. In order to address this problem with the treatment of cSDH, many studies exist that compare the effectiveness of various treatment modalities. Two recently developed treatment options of cSDH include middle meningeal artery (MMA) embolization and use of self-irrigating catheter systems. To our knowledge there have been no reported cases of combining the use of these new treatments. What follows is a case report of a 72-year-old patient with recurrent cSDH following MMA embolization who underwent minimally invasive surgical drainage of his hematoma using an IRRAflow catheter (IRRAS, San Diego, CA, USA).
