Penile arterial blood pressure/brachial arterial blood pressure

The penile artery index is usually used to indicate the blood pressure status of the penile artery, and the penile artery index = penile artery blood pressure / arm artery blood pressure. The normal penile artery index is close to 1.0, and it is normal to exceed 0.8. When the penile artery blood pressure is 30 mmHg (4.0 kPa) lower than the systemic mean arterial blood pressure, or the penile artery index is lower than 0.6, it is abnormal. 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 damage liver and kidney function. Basic Information Specialist classification: male examination inspection classification: other inspection Applicable gender: whether the male is fasting: not fasting Tips: On the morning of the medical examination, you should fast and ban water. I have had surgery and I have to bring relevant medical records and related information. Normal value The normal penile artery index is close to 1.0, and it is normal to exceed 0.8. Clinical significance Abnormal results: When the penile artery blood pressure is 30 mmHg (4.0 kPa) lower than the systemic mean arterial blood pressure, or the penile artery index is below 0.6, it is abnormal. The measurement of penile artery blood pressure is often not constant, which is due to both technical limitations and the effects of penile vascular response on the environment and mood. Therefore, if an abnormal result is measured, it is necessary to repeatedly measure and verify that the penile artery index abnormality may be made. Penile artery blood pressure measurement may be helpful in diagnosing arterial insufficiency, but it is not very reliable to use this test to exclude arterial insufficiency as the cause of impotence. Moreover, it does not clarify any condition of blood flow, and it is even less able to detect penile artery function in an erect state. People who need to be examined: patients with insufficient blood supply to the penile artery and impotence. Low results may be diseases: penile abnormal erection precautions 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 damage liver and kidney function; 2. Pay attention to rest before the physical examination, avoid strenuous exercise and emotional excitement, and ensure adequate sleep, so as not to affect the physical examination results. It is best to take a bath. 3. If you have had surgery, you should bring relevant medical records and relevant 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. Not suitable for the crowd No taboos. Adverse reactions and risks No complications.
