Distribution of atherosclerotic vascular lesions in the intracranial posterior circulation has not been as well documented as in the anterior circulation. Data regarding this aspect among Asian stroke patients are scarce. In present study, we sought to investigate the distribution of posterior circulation vascular lesions in Chinese stroke patients. We examined consecutive patients with acute i...

BACKGROUND AND PURPOSE Detection of acute infarction in the posterior circulation is challenging. We aimed to determine the additional value of tomograpy (CT) perfusion to noncontrast CT and CT angiography source images for infarct detection and localization in patients suspected of acute ischemic posterior circulation stroke. METHODS Patients with suspected acute ischemic posterior circulati...

Amongst various mechanisms of presyncopal events, posterior circulation disease needs to be considered. This particular mechanism has been underrecognized. We describe a case of a 76-year-old patient with recurrent posterior circulation TIAs, presenting as recurrent prolonged presyncopal events.

OBJECTIVE to evaluate clinical, radiological, and prognostic features of patients with multiple acute infarcts in remote arterial territories of the posterior circulation. DESIGN Data analysis from a prospective acute stroke registry in a community based primary care centre using a standard protocol including MRI and MRA. RESULTS In three and a half years, 27 of the 236 patients (11%) with ...

N Engl J Med 2005;352:2618-26. Copyright © 2005 Massachusetts Medical Society. ighty percent of strokes are ischemic. twenty percent of ischemic events involve tissue supplied by the posterior (vertebrobasilar) circulation (Fig. 1). The paralysis of vertebrobasilar stroke can be devastating, and some forms have high rates of death. 1 Many cases of vertebrobasilar disease remain undiagnosed or a...

Complex posterior circulation aneurysms are formidable lesions with an abysmal natural history. Their management continues to present a challenge to both endovascular and open microsurgical approaches. Affording an expansive, combined supra- and infratentorial exposure, the petrosal approaches are well suited for these challenging lesions when located along the basilar trunk or at a low-lying b...
