Objective:
To discuss the treatment of chronic subdural hematoma by minimally invasive drilling and drainage.
Methods:
The clinical data were collected and analyzed for 118 cases with chronic subdural hematoma at our hospital from May 2003 to August 2011. They underwent minimally invasive drilling and drainage.
Results:
A total of 101 cases (85.6%) were cured and 17 cases (14.4%) improved. Hematoma recurred in 6 cases (5.08%). Among them, 5 cases recurred at Months 1-2 and 1 case at Month 77 post-operation. Three cases died. The causes included heart failure (n = 1), cirrhosis and renal failure (n = 1) and sudden cardiac death (n = 1). Six recurrent cases were cured by minimally invasive drilling and drainage. And 85 cases received a follow-up period of 1 - 80 months. No further recurrence was found for 6 recurrent cases.
Conclusion:
The treatment of chronic subdural hematoma by minimally invasive drilling and drainage is safe, simple and efficacious.
