Comparative Study
Impact of ruptured cerebral aneurysm coiling and clipping on the incidence of cerebral vasospasm and clinical outcome.
This study assessed the impact of treatment modality of aneurysmal subarachnoid hemorrhage (aSAH) on the rate of vasospasm (VSP), mortality, and hospital length of stay (LOS) of patients with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Our study reveals that EC has a lower rate of VSP, shorter LOS, and comparable mortality to SC in aSAH.

Acute ischemic stroke treatment is meant to induce early reperfusion before ischemic lesion becomes definitive; unfortunately, in many cases, recanalization occurs too late. We present a case in which oxygenated blood was perfused through the occluding clot during intra-arterial (IA) thrombolysis to anticipate reperfusion. ⋯ Momentary reperfusion of ischemic penumbra with oxygenated blood is feasible and may allow to "buy time" until definitive reperfusion is achieved.

Cerebral toxoplasmosis is a frequent complication in immunosuppressed patients such as AIDS (acquired immunodeficiency syndrome). Frequently, lesions are located deep in the brain which are inaccessible for biopsy making rapid diagnosis dependent on accurate interpretation of neuroimaging findings. The commonest cranial CT findings reported in toxoplasmosis are ring enhancing hypodense lesions in basal ganglia or cortical gray matter. ⋯ Six patients had hemorrhage at the time of initial clinical presentation and one developed hemorrhage following 2 weeks of antitoxoplasma treatment. We conclude that hemorrhagic lesions are frequently found on cranial MRI scans in cerebral toxoplasmosis. AIDS patients presenting with hemorrhagic cerebral lesions should be considered for a trial of presumptive antitoxoplasma treatment.
