Laser Doppler imaging is a new, non-invasive technique allowing the spatial distribution and the temporal variation of the skin blood flow to be monitored. A mean blood flow value over an area, such as the finger-tip in the present study, can also be calculated. Recordings from 12 patients with a sutured ulnar artery following trauma did not significantly differ from those obtained in 14 controls. Four patients with a ligated ulnar artery, however, showed a slower restitution of blood flow values after cold provocation. All sutured ulnar arteries were found to be patent, which confirms that microvascular reconstruction of an injury to the ulnar artery at the wrist is worthwhile.

Abstract Objective: To investigate the blood flow distribution in the repaired lip of cleft patients using a laser Doppler imager and to evaluate the difference in blood flow of the scar tissue between unilateral cleft lip patients with and without cleft palate. Materials and Methods: Twenty patients with either unilateral cleft lip only (CL group, n = 8) or cleft lip and palate (CLP group, n = 12) were used as subjects. The blood flow of the upper lip was two-dimensionally visualized by a color scale alongside the corresponding photo image of the tissue surface with laser Doppler imaging. The upper lip photo image was divided into five regions: scar, white lip on the cleft side, white lip on the noncleft side, red lip on the cleft side, and red lip on the noncleft side. The average flux score (AFS), which is proportional to blood flow, was analyzed in each region. Results: The AFS for the scar region was significantly (P < .05) lower than in the other four regions. The AFS for the red lip on the cleft side was not significantly different from that for the noncleft side. The white lip revealed a significantly (P < .05) higher score on the cleft side than on the noncleft side. The AFS ratio (AFS in the scar region/AFS in the white lip region) was significantly (P < .01) lower in the CLP group than in the CL group. Conclusions: These results suggest that blood flow distribution in the repaired lip might be affected by the anatomic features of the cleft.

Diffuse Liver Diseases

Currently, it is necessary to find additional reliable technique (and without prejudice to the health of the patient with diffuse liver disease) to determine the stage of the disease, to quickly evaluate the degree of fi-brosis, including dynamics, as well as to predict the further course of the disease. It is known that changes in patients with diffuse liver disease at the vascular level are systemic in nature. Identification of these changes may help predict disease course, the possibility of the therapy revising. Clinical perspectives, the benefits of using non-invasive laser Doppler imaging as a method of diagnosis of the microvasculature in patients with diffuse liver diseases are discussed in this paper. 40 patients with alcoholic liver cirrhosis, with steatohepatitis mixed etiology, viral hepatitis "B" and "C" of varying degrees of activity, which conducted the study of microcirculation using non-invasive laser Doppler were examined.
