Introduction
RECURRENCE, CHRONIC SUBDURAL HEMATOMA
A chronic subdural hematoma (cSDH) consists of a collection of old blood and degraded blood products located in the subdural space. A process driven by inflammatory and angiogenetic factors may cause the subdural collection of blood to progress to a significant volume causing symptoms due to compression of the brain.The most common surgical technique is evacuation via 1 to 2 cranial burr holes combined with the use of a postoperative drain.In theory, irrigation fluid temperature may influence recurrence rates after cSDH surgery. The increased solubility with irrigation fluid at body temperature compared with room temperature may facilitate cSDH clearance.
