Abstract

Aim. The study is devoted to the blood flow analysis in the basins of the radial and ulnar arteries and the evaluation of the prevalence of the palmar arcs formation types. Material and Methods. The research was performed on a dispensary basis using the technique of ultrasound dopplerography supplemented with a functional Alain probe on the Samsung Medison R7 and Aloka SSD 3500 devices. 50 patients of both sexes aged from 32 to 85 years (mean age of 51 years) were examined. Data analysis was processed with Microsoft Excel 2007 software. Results and Discussion. It was found that the average diameter of the radial and ulnar arteries in the total sample remains constant and is practically equal for the both radial artery - 1.77 mm (minimum diameter 1.3 mm, maximum - 2.7 mm) and ulnar - 1.78 mm (minimum diameter 1.4 mm, maximum - 2.9 mm). Peak blood flow rates obtained with pulsed wave doppler ultrasonography were also characterized for both arteries with a small difference, in the radial artery - 31.16 cm/sec (minimum speed is 5.6 cm/sec, maximum - 62.4 cm/sec), in the ulnar - 34.45 cm/sec. (minimum speed is 5.2 cm/sec, maximum - 77.55 cm/sec). The median for the both arteries estimation was also not significantly different: for the radial artery - 31 cm/sec, for the ulnar artery - 33.8 cm/sec. When the Allen test was performed, it was found that in 50% of cases the pronounced blood supply of the palmar arcs from the ulnar arteries basin was observed, in 18% of cases it was registered in the radial arteries, and in 32% as a result of the measurement there was no significant change in the blood flow parameters or the result was doubtful. Conclusions. As a result of observation, the dominant role of the ulnar artery in the formation of arterial palmar arches of the hand was confirmed. A clinically significant group of patients with a high risk of complications in cases of exclusion from the active bloodstream of the radial artery has been identified.
