Clinical analysis of 11 patients with capsular warning syndrome / 中华神经科杂志

ABSTRACT

Objective To evaluate the relationship between stenosis of intra- or extra-cranial cerebral large artery and capsular warning syndrome(CWS). Methods Eleven consecutive CWS patients hospitalized during period of time from November 2008 to December 2009 were retrospectively analyzed.Result In these 11 patients with CWS, 5 patients had motor symptoms only, 4 patients had pure sensory symptoms, and 2 patients had sensorimotor symptoms. Ten patients underwent cervical contrast-enhanced MRA and intracranial MRA examination. The results showed no sign of arterial stenosis. Seven CWS patients eventually had strokes, 1 progressed to stroke despite receiving the therapy of antiplatelet and anticoagulation. All stroke lesions were located in the capsula interna. All the CWS patients had vascular risks 7 were smoker, 8 had hypertension, 1 had diabetes mellitus, and 5 had hyperlipidemia. One patient had a history of previous stroke; no patient had a history of ischemic heart disease or atrial fibrillation. At follow-up(10. 2 ±3.4)mouths, the average modified Rankin scale score for all patients was 0. 73 ± 1.20.Conclusion CWS was not associated with stenosis of the intra and extra-cranial large cerebral arteries.CWS may be associated with small-vessel single-penetrator disease.
