Abstract:
From January 2005 to December 2009, 20 patients have been treated for bilateral chronic subdural hematoma at the Grand Yoff General Hospital in Dakar, Senegal. This was a retrospective study concerning clinical, imaging, and therapeutic issues faced and comparing them to unilateral chronic subdural hematoma issues recorded during the same time period.
Abstract:
Median age was 71 years old, ranging from 35 to 95 years old. 17 patients were male and were 3 female. Previous head trauma had been reported for 55% of the patients, high blood pressure - associated or not with diabetes mellitus - had been recorded in 45% of the patients.
Abstract:
Clinical symptoms were marked by high intracranial pressure and motor deficits in 70% of cases and 40% showed a mental confusion.
Abstract:
Brain CT scans were the key diagnostic tools; all patients undertook a scan and results demonstrated blood subdural collection with variable density in the right brain hemisphere (in 30% of cases).
Abstract:
The focus of the surgical treatment was a bilateral burr hole, evacuation of the hematoma and no more than 3 days of postoperative drainage. The medical treatment consisted of an adapted hydro-electrolytic rehydration. The outcome of treatment was positive for 17 patients (85%), 2 patients suffered from subsequent hematoma and 1 patients passed away.
