Modelling the leptomeningeal collateral circulation during acute ischaemic stroke

Semi-quantitative and qualitative evaluation of pial leptomeningeal collateral circulation in acute ischemic stroke of the anterior circulation: the Careggi Collateral Score.

INTRODUCTION The imaging of ischemic penumbra in acute stroke is a debated issue and establishing commonly accepted criteria is difficult. Computerized tomography-perfusion studies conducted in animals have showed that the modifications occurring in the brain parenchima are part of a dynamic and progressive process involving the microcirculation. The purpose of this paper is to propose a new an...

Posterior circulation ischaemic stroke.

There are important differences between posterior and anterior circulation stroke. The differences include the value of screening instruments, optimum diagnos‐ tic modalities, and clinical features (table). The face arm speech test (FAST), a widely used prehospital stroke recognition screening instrument, is less sensitive for detecting posterior circulation stroke than for anterior cir‐ culati...

Acute ischaemic stroke: part II. The vertebrobasilar circulation.

OBJECTIVE To review recent advances in the management of acute ischaemic stroke in a two part presentation. DATA SOURCES Articles and a review of studies reported from 1990 to 2000 and identified through a MEDLINE search of the English language literature on acute ischaemic stroke. SUMMARY OF REVIEW An acute ischaemic stroke of the vertebrobasilar circulation is investigated initially with ...

Acute ischaemic stroke: part I. The carotid circulation.

OBJECTIVE To review recent advances in the management of acute ischaemic stroke in a two part presentation. DATA SOURCES Articles and a review of studies reported from 1990 to 2000 and identified through a MEDLINE search of the English language literature on acute ischaemic stroke. SUMMARY OF REVIEW An acute ischaemic stroke is characterised clinically by the rapid development of a neurolog...
