Abstract


OBJECTIVE
Chronic subdural hematoma is a common disorder observed in neurosurgical care and the recurrence rate is relatively high. In this report, we evaluated the relationship between the recurrence rate of chronic subdural hematoma and the postoperative head position of the patient.
METHODS
We conducted a retrospective study of 72 patients with unilateral chronic subdural hematoma treated by burr hole surgery with closed system drainage from October 2009 to May 2011. In group A, there was no restriction in head position for days keeping the catheter. In group B, the patients were placed with the lesion side of the head downward after the operation. We analyzed the recurrence rate, amount of postoperative drainage and changes in computed tomography finding of group A and B.
RESULTS
Group A and group B consisted of 36 cases, respectively. The mean amount of total postoperative drainage was 248.8+/-127.2 mL in group A and 176.3+/-98.9 mL in group B (p=0.01). The improvement rates of midline shifting before and after surgery showed 60.5+/-25.6% in group A and 73.4+/-26.3% in group B (p=0.039). The total recurrence rate in group A was 11.1% and 5.6% in group B.
CONCLUSION
By facing the lesion downward after surgical treatment, chronic subdural hematoma is thought to help reexpand the brain and to prohibit cerebrospinal fluid from flowing into subdural space and to decrease the recurrence rate better than having a free position.
