Haegelen C - - 2005
Spinal meningiomas are usually benign, slow-growing tumours and are commonly associated with good patient outcome following surgery. However, the existence of a severe preoperative neurological deficit has been considered to be a possible predictor of poor functional outcome after surgery. We retrospectively reviewed data from 33 patients with 35 spinal ...

There are relatively few reports detailing the outcome of children and adolescents with arteriovenous malformations (AVMs) treated with stereotactic radiosurgery (SRS). We reviewed our experience over the past decade to determine whether the outcomes and toxicity were similar to those reported in adults. Seventeen patients 18 years of age or ...

OBJECTIVE: Animal models and clinical studies suggest that intraventricular thrombolysis improves clot resolution and clinical outcomes among patients with intraventricular hemorrhage. However, this intervention may increase the rates of rebleeding and infection. To assess the safety and efficacy of intraventricular thrombolysis, we conducted a pilot, randomized, double-blind, controlled, multicenter study. ...
