Chronic Subdural Hematoma (CSH) is Still an Important Clinical Problem. Analysis of 700 Consecutive Patients.

backgroundChronic subdural hematoma (CSH) is still an important neurosurgical problem and the number of patients increases despite the progress in early diagnosis of cerebral lesions. METHODOLOGY: We analyzed a group of 700 consecutive patients treated in neurosurgical departments for CSH. Clinical state on admission was evaluated according to the Markwalder scale, all patients had CT studies and were operated using craniotomy or burr holes with closed system drainage techniques.

resultsMore than 50% had extensive intracranial bleeding, almost half of the patients were treated with oral anticoagulants. The patients with extensive fresh bleeding were in significantly worse states on admission and were treated by craniotomy and external capsulectomy (42%). All the others had burr holes and closed system drainage of the subdural space. Results of treatment were acceptable, 2% died, and 1.5% remained vegetative, due to massive hemorrhage and severe neurological deficits on admission.

conclusionsDespite a progress in diagnosis, CSH still remains an often cause of severe intracranial complications. The rising number of occurrences of this lesion is strictly connected with a wide use of oral anticoagulants. Surgical removal of CSH still remains the best type of treatment for such lesions.
