Single Burrhole Craniostomy with Subdural Placement of Foley Catheter for Drainage of Chronic Subdural Hematoma

Abstract

Objective: Chronic subdural hematoma (CSDH) is a common neurosurgical condition of the elderly. The lack of consensus over a single standard surgical procedure for the management of CSDH urges neurosurgeons to evaluate different techniques in terms of a better outcome.
 Material & Methods: In this prospective study forty cases of CSDH who had undergone single burr-hole craniostomy and subdural placement of Foley catheter were analyzed. The observations were made concerning clinical, radiological findings, postoperative complications, and mortality rate.
 Results: The study included 26 males and 14 females with a mean age of 67 years. The most common presenting symptom was hemiparesis (n=18, 45%). Recurrent hematoma and recurrent evacuation rate was 10%. There was no case of newly developed postoperative seizures, pneumocephalus, intracranial hemorrhage, and wound infection. The mortality rate during the study was 0.0%. The mean Glasgow outcome score (GOS) at the time of discharge was 4.8.
 Conclusion: We concluded that single burr-hole evacuation of CSDH with Foley catheter placement appears to be an effective procedure with a significant reduction in postoperative pneumocephalus. Factors such as sudden decompression of hematoma, the air in the subdural cavity, misplacement of drainage tubes, and damage to blood vessels during surgery can be reduced with this technique.
