8 patients suffering from severe head injury (Glasgow Coma Scale score of 3-5) were treated with the calcium influx blocker nimodipine (2-3 mg/h) for a traumatic cerebral vasospasm. In every case the spasm involved the frontal region of the circle of Willis with the first two segments of the anterior and middle cerebral artery. Control angiograms, recorded in 6 patients, revealed a dilated or normalized lumen of the vessels that the first angiography had revealed to be spastic. The intracranial and the mean arterial pressure were not altered by nimodipine during simultaneous neurosurgical intensive care therapy (dexamethasone, mannitol, relaxation, and controlled respiration for 2-3 days). Monitoring of the somato-sensory evoked potentials (SEP) showed a distinct improvement of the cortical response within 7 days. One patient died of sepsis 8 days after the accident and one remained in a vegetative state. The remaining patients reached Glasgow Coma Scale scores of 13.0 +/- 1.1. within 8.6 +/- 2.2 days, the initial scores having been 4.1 +/- 0.8. One year after their accident all the patients were once again fully able to work. The survival quality was therefore better than that reported in the literature for patients in similar conditions. We conclude from these preliminary results that calcium influx blockers can be used successfully in the therapy of traumatic vasospasm and of severe head injuries. A study involving a larger number of patients is currently in progress.
Out of a series of 252 patients who underwent aneurysm surgery, 19 (7.5%) were operated on in a "peracute stage" in the poor grades Hunt & Hess IV (n = 11), IV-V (n = 2), and V (n = 6). All patients suffered from large aneurysmal intracerebral hematomas which were evacuated after decompressive craniotomies, all aneurysms (ACA: n = 1, ACoA: n = 4, MCA: n = 12, ICA: n = 2) could be clipped. 4 patients died within the first 3 postoperative days, 6 patients reached a poor result remaining in an apallic syndrome or a state of high invalidity, 8 obtained a fair result with personal autonomity, and 1 patient recovered completely. Although this kind of aneurysm bleeding is combined with high mortality and morbidity, we nevertheless emphasize its surgical treatment as soon as possible because of the lack of other efficient therapeutical procedures.
The case of a 30-year-old man with posttraumatic syringomyelia involving the cervical and upper thoracic spine is reported. The patient was followed clinically and with magnetic resonance (MR) imaging over a 3-year period. Spontaneous complete remission of the syrinx-related symptoms correlated with a partial collapse of the syrinx, as proved by serial MR imaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
