Experiences in the management of brainstem hematomas.
The purpose of this study was to present our experience in the management of spontaneous brainstem hematomas (BSH). Records of 58 consecutive patients were reviewed, including demographic data, symptoms, Glasgow Coma Scale, treatment, intraoperative findings (in surgical cases), and outcome according to the Glasgow Outcome Scale. Fifteen patients were comatose (GCS 4 or less): 11/15 patients were treated conservatively. Four patients with accompanying acute occlusive hydrocephalus were treated by placement of an external ventricular drainage. None survived. In nine patients (60%), arteriosclerosis and/or long-standing arterial hypertension were known and arteriopathic BSH was suspected. Forty-three patients were not comatose: 37 patients showed no impairment of consciousness (GCS 15), 6 patients presented with mild disturbance of conscious state (GCS 13), progressing to coma (GCS 8) in 1. In the majority (36/43) of the non-comatose patients (83.7%) cavernoma could be revealed and removed surgically. In six patients (14%), an atypically located arteriopathic BSH was assumed and treated medically. One patient had an underlying brainstem arteriovenous malformation and was treated radiosurgically. Many arteriopathic BSH cause immediate coma indicating direct and irreversible damage of midpontine structures. Thus, we suggest not to proceed to surgery, even if the bleeding is accompanied by acute hydrocephalus. The majority of BSH not resulting in immediate coma are caused by underlying cavernomas. In these cases surgery should be considered.
