FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely, to neurology, cardiology and ultrasonic diagnostics. Suspension of air microbubbles, obtained by mixing of 9 ml of physiological solution and 1 ml of sterile air is introduced to patient intravenously, at this background estimation by ultrasonic examination is carried out. Ultrasonic examination is carried out in form of contrast bilateral transcranial Doppler monitoring of blood flow in both medial cerebral arteries at rest and while performing Valsalva test with calculation of microembolic signals. Open oval opening is referred to small sizes, corresponding in average to 1.5 mm, if at registration from 1 to 20 microembolic signals are detected. Open oval opening is referred to midium sizes, corresponding in average to 2 mm, if at registration over 20 microembolic signals are detected. Open oval opening is related to large sizes, corresponding in average to 3.5 mm, if "curtain" from non-calculable number of microembolic signals is registered.
EFFECT: method extends arsenal of means for estimation of size of open oval heart opening in case of ischemic stroke.
