Abstract

Background. The aim of study was to answer whether acute phase of ischemic stroke may provoke upper limb capillary changes. We also tried to assess the character of the changes and the correlation between them and severity of ischemic stroke its acute phase as well as coexisting factors, which may facilitate skin capillary circulation abnormalities, i.e. blood hypertension, diabetes mellitus t. 2, and smoking.
Material and methods. A qualitative and quantitative analysis of nailfold capillaries of upper limbs was done on 92 patients: 39 women and 53 men aged 46–92 years (on the average 67.7 yrs) admitted to the Department of Neurology between 2002 and 2003 because of first-ever episode of ischemic stroke. Control group consisted of 30 individuals: 13 women and 17 men suffered from diseases, which should not influence the capillaries. The nailfold capillaroscopy was done by means of Olympus PV10 videomicroscope connected with the KONTRON KS-100 v. 2.0 imaging system (license No. 0100176). The assessment has been done twice: on the first and 7th–10th day after ischemic stroke onset.
Conclusions. In patients with ischemic stroke the skin capillaries of fingers appeared to be dilated. It was found in both upper limbs, but the dilation was significantly more distinct in arm involved by stroke. The skin capillary loops dilation was transient and disappeared within acute phase of stroke. Transient central and peripheral autonomic disregulation in the initial period of stroke is probably responsible for capillary dilation. The extent of dilation does not depend on intensity of paresis, however it correlated with smoking.
