Ankle Brachial Index

Anklebrachial index (ABI) is the most common and simple method of vascular surgery. The ankle arterial pressure and radial artery pressure are obtained by measuring the systolic pressure of the posterior tibial or anterior tibial artery and the iliac artery. The ratio between the two. The normal person's resting index ranges from 0.9 to 1.3. Below 0.8 indicates a moderate disease, and below 0.5 indicates a significant disease. Patients with intermittent claudication have an index of sputum between 0.35 and 0.9, while patients with resting pain often have a sputum index of less than 0.4. It is generally believed that such patients may be at risk of amputation if they are not actively treated. Basic Information Specialist classification: cardiovascular examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Tips for other diseases may suggest further examination of the diagnosis. Normal value: 踝肱 index range: 0.9-1.3 Above normal: Tips for other diseases may suggest further examination of the diagnosis. negative: Positive: Tips: When you check, you should relax, actively face, and actively cooperate with the inspection. Normal value When the normal person is at rest, the 踝肱 index ranges from 0.9 to 1.3. Clinical significance Abnormal results: Below 0.8 indicates a moderate disease, and below 0.5 indicates a predisposed disease. Patients with intermittent claudication have an index of sputum between 0.35 and 0.9, while patients with resting pain often have a sputum index of less than 0.4. It is generally believed that such patients may be at risk of amputation if they are not actively treated. When the sputum index is greater than 1.3, it suggests that the vascular wall is calcified and the blood vessels lose their contractile function, which also reflects severe peripheral vascular disease. People who need to be examined: People who have intermittent behaviors. Positive results may be diseases: ankle joint tuberculosis, ankle cartilage injury precautions Taboo before inspection: no special contraindications. Requirements for inspection: Check the feelings of relaxation, face positively, and actively cooperate with the inspection. Inspection process The patient was placed supine, and the 12 cm × 40 cm cuff was placed on the bilateral ankle and upper arm respectively. Doppler stethoscope was used to assist in measuring the systolic pressure of the dorsal or anterior tibial artery, posterior tibial artery and radial artery. The ratio between the two is 踝肱 index. Normally ABI ≥ 0.97. 0.97 ~ 0.9 is the critical value. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks Nothing.
