Description

TECHNICAL FIELD

[0001] The utility model relates to neurosurgery minimally invasive operation technical field, concretely is accurate positioning meningeal artery guide plate. BACKGROUND

[0002] Chronic subdural hematoma (CSDH) often occurs after head trauma, the hematoma is located between the dura mater and arachnoid membrane, and is wrapped by a false capsule outside. It is a common disease in neurosurgery. Drilling drainage is the preferred surgical method for CSDH. But hematoma recurrence is still one of the common complications after CSDH drainage. At present, there are many methods to prevent hematoma recurrence after CSDH surgery, including changing postoperative position, taking hormones and statins after surgery, etc., but there is no optimal treatment plan. Related researches point out that the capillary on the false capsule of CSDH may be one of the reasons for inducing hematoma recurrence, and the source of such capillary is the middle meningeal artery (MMA). Therefore, blocking the affected side MMA during drainage may have a positive effect on reducing CSDH recurrence. There are reports that the middle meningeal artery embolization is used to treat chronic subdural hematoma.
