FIELD: medicine, cardio-vascular surgery.
SUBSTANCE: one should perform ultrasound scanning of the 1st volar metacarpal artery both before and at the background of radial artery compression, moreover, at decreased peak systolic rate of circulation in the 1st volar metacarpal artery at the background of compression by 40% or less against peak systolic rate of circulation before compression one should diagnose ulnar type of wrist's circulation and at decreased peak systolic rate of circulation at the background of compression by more than 40% against peak systolic rate of circulation before compression or at appearance of retrograde circulation one should diagnose radial type of wrist's circulation.
EFFECT: higher efficiency and accuracy of diagnostics.
