Pelvic steal test

The pelvic stealing test is to measure the penile/arm blood pressure index before exercise, and let the patient exercise the thigh and buttock muscles for a few minutes and see if the index is lower than before exercise. Basic Information Specialist classification: male examination inspection classification: ultrasound Applicable gender: whether the male is fasting: fasting Tips: A few days before the physical examination, pay attention to diet, do not eat too much greasy, not easy to digest food, do not drink. Normal value The penile artery index decreased within a range of 0.1. Clinical significance Abnormal results: penile artery index decreased by more than 0.1 can be diagnosed as vascular impotence. People who need to be examined: patients with vascular impotence. High results may be diseases: impotence notes Taboo before inspection: 1. A few days before the physical examination, pay attention to diet, do not eat too much greasy, non-digestible food, do not drink alcohol, do not eat drugs that have damage to liver and kidney function. 2, the day before the physical examination should pay attention to rest, emotional, and ensure adequate sleep, so as not to affect the results of physical examination. It is best to take a bath. 3. If you have had surgery, you should bring relevant medical records and related information. 4. On the morning of the medical examination, you should fast and ban water. Requirements for inspection: 1. Don't be shy and nervous when checking, to avoid blood flow acceleration and affect the test results. 2, when lying on the tester should be lying flat, do not move randomly when checking. Inspection process The paralyzed patient lies flat on the detector, and sends an ultrasonic wave to the human blood vessel through the ultrasonic probe. The echo signal is received by the probe, and the penile cavernous artery blood vessel is detected, and the penile artery index is automatically calculated by the computer to determine whether the impotence is due to the penis. Caused by insufficient arterial blood supply. The principles for judging the results of penile blood pressure measurement are as follows: (1) When the penile artery index of at least one artery is <0.6, the penile erectile function is impaired (very rare, only one arterial index is <0.6, while the other three arteries are normal), and the reading of the corpus cavernosum artery is most meaningful. . (2) When one or more arteries are between 0.6 and 0.8, it indicates that the vascular function is insufficient. (3) All arterial indices are above 0.8, indicating that the penile vessels are functioning well. (4) When the difference in systolic blood pressure of the bilateral corpus cavernosum reaches 30 mmHg (4.0 kPa), it indicates that the internal pudendal artery and its branches have clinically significant damage. After measuring the penile/arm blood pressure index before exercise, let the patient exercise the thigh and buttock muscles for a few minutes and see if the index decreases compared with before exercise. Not suitable for the crowd No taboos. Adverse reactions and risks No complications.
