Abstract

Background and purpose. Sensorimotor stroke (SMS) is often included among the lacunar syndromes, although the underlying cause of this stroke-subtype is less well documented. To this end we analysed 32 patients presenting with a sensorimotor syndrome. Methods. The study protocol included vascular risk factors, echocardiography, Doppler sonography of carotid arteries, CT scan and MRI of the brain. Results. There were 23 men and 9 women, mean age 65.7 years. Hypertension was present in 28% and diabetes in 19%. In all, 63% had sensorimotor deficit of faciobrachiocrural areas and 37% had faciobrachial or brachiocrural deficits. MRI disclosed a presumably relevant infarct in 26 patients (81%); 20 patients (62%) localized to the territory of... (More)

Background and purpose. Sensorimotor stroke (SMS) is often included among the lacunar syndromes, although the underlying cause of this stroke-subtype is less well documented.

The study protocol included vascular risk factors, echocardiography, Doppler sonography of carotid arteries, CT scan and MRI of the brain. Results. There were 23 men and 9 women, mean age 65.7 years. Hypertension was present in 28% and diabetes in 19%. In all, 63% had sensorimotor deficit of faciobrachiocrural areas and 37% had faciobrachial or brachiocrural deficits. MRI disclosed a presumably relevant infarct in 26 patients (81%); 20 patients (62%) localized to the territory of small perforating arteries, 3 patients (9.5%) in the internal borderzone, and 3 patients (9.5%) in cortical territories. Eight of 20 deep infarcts were larger than 15 mm. No hemorrhage or non-vascular lesion was found. A potential cardioembolic source was present in 5 patients (16%), whereas 2 patients (6%) had an ipsilateral carotid stenosis > 50%. Conclusions. Small vessel disease was the most likely cause in 69% of our patients with SMS, whereas 31% had a potential cardioembolic source, large artery disease or infarcts not compatible with perforating artery disease.
