Multicenter Study
Risk factors for early death in acute ischemic stroke and intracerebral hemorrhage: A prospective hospital-based study in Asia. Asian Acute Stroke Advisory Panel.
In Asia, there has been no international study to investigate the risk factors for early death in patients with ischemic stroke and intracerebral hemorrhage. ⋯ In Asian patients with stroke, previous use of antiplatelet drugs nearly halved the risk of early death in patients with ischemic stroke, whereas atrial fibrillation, ischemic heart disease, diabetes, and ex-smoker status were risk factors for early death. Among patients with intracerebral hemorrhage, diabetes was associated with early death, whereas young age group and hypertension were associated with lower death rates, though no clear explanation for the hypertension association could be discerned from the data available.

We sought to determine whether postoperative length of stay (LOS) and resource utilization could be safely reduced without changing our uniform protocol of performing carotid endarterectomy (CEA) under general anesthesia with postoperative intensive care unit monitoring. ⋯ A uniform policy of discharge home from the intensive care unit on postoperative day 1 following CEA under general anesthesia can reduce LOS and decrease resource utilization without compromising care.

Comparative Study
Initial loss of consciousness and risk of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.
Delayed cerebral ischemia (DCI) is a major cause of death and disability in patients with aneurysmal subarachnoid hemorrhage. We studied the prognostic value for DCI of 2 factors: the duration of unconsciousness after the hemorrhage and the presence of risk factors for atherosclerosis. ⋯ The duration of unconsciousness after subarachnoid hemorrhage is a strong predictor for the occurrence of DCI. This observation may contribute to a better understanding of the pathogenesis of DCI and increased attention for patients at risk.

Revascularization surgery for moyamoya patients is believed to prevent cerebral ischemic attacks by improving cerebral blood flow. However, measures preventing the occurrence of hemorrhagic moyamoya in patients have not yet been established in the literature due to the low rate of hemorrhage onset as well as the originally limited numbers of patients with moyamoya disease, poor understanding of the clinical course of rebleeding, correct surgical management, and long-term outcome. We present here the results of an overall survey of patients with hemorrhagic moyamoya disease in a district of Miyagi Prefecture in Japan and examine their clinical course, efficacy of revascularization surgery, and long-term outcome. ⋯ In this study, we compiled the results of meticulous follow-up conducted over the past 10 years for patients with hemorrhagic moyamoya disease. Because hemorrhagic moyamoya disease is known for its high rate of mortality at the time of rebleeding and often causes rebleeding long after the initial episode (as much as 20 years later), implementation of long-term preventive measures for rebleeding is necessary. This suggests that a long-term prospective study of a large number of patients with hemorrhagic moyamoya disease is required to determine whether bypass surgery prevents rebleeding of hemorrhagic moyamoya disease.

Coagulation disorders can cause intracerebral bleeding that may be difficult to detect since subsequent aberrant clot formation may mask early detection. This is an important pitfall because, when diagnosed early, bleeding in these patients is treatable. ⋯ Intracerebral hemorrhage must be strongly suspected in any patient with a coagulation disorder presenting with matching clinical symptoms. Therapy must be installed immediately, before additional investigations, and should be continued even when initial neuroimaging is negative.
