The purpose of the present retrospective study is to analyse 14 patien
ts harbouring brainstem haematomas and to discuss the early and late p
rognosis. The patients were divided into two groups: group A (survivor
s), 8 patients with follow-up duration ranging between 8 months and 12
years; and group B (nonsurvivors), 6 patients. At the time of onset o
r hospital admission, the former were under 50 years of age and had no
important clinical history. Their degree of consciousness was altered
only slightly or moderately and their patients in this group underwen
t surgical treatment. The members of group B, who died within days of
their admission to the hospital, were over 60 years of age, had a numb
er of clinical antecedents and severe alterations of consciousness, wh
ile 83% of them presented diffuse brainstem haemorrhages. None of the
patients of this group were treated surgically. It was concluded that:
1) the indications for surgery for these lesions were progressive hyd
rocephalus, increase in the mass effect with progressive symptomatolog
y and suspected ''cryptic vascular malfomation'' with risk of later re
bleeding or brain tumour; 2) surgical treatment was necessary to impro
ve the symptomatology in 3 patients in group A, although there were no
significant differences between surgically treated and nonsurgically
treated patients in the same group with respect to prognosis; 3) age,
clinical history, degree of alteration of consciousness and type of ha
emorrhage are the major factors affecting the early and late prognosis
of brainstem haemorrhages.
