Acute traumatic posterior fossa subdural haematomas.

ABSTRACT

Acute Posterior Fossa Subdural Haematoma (PFSDH) caused by trauma is a clinical rarity only 13 cases have been encountered in the literature. Three consecutive personal cases of PFSDH are presented. Two of them are respectively the sixth and the seventh surgically treated cases with success. Among the 16 cases 60% had a sudden clinical worsening within 24 hours. Seven cases had an occipital fracture. Of the thirteen cases operated upon 11 (85%) were in a state of deep coma. The surgical mortality was 46%. One patient had a good recovery (Grade 5) and six a moderate disability (Grade 4) on the Glasgow Outcome Scale. We conclude that surgical treatment must always be carried out even in patients presenting in an agonal state.
