nilkkaolkavarsimittaukseen

Nilkkaolkavarsimittaus, often translated as ankle-brachial index (ABI) measurement, is a non-invasive diagnostic test used to assess the blood flow in the lower extremities. It compares the blood pressure in the ankles to the blood pressure in the upper arms. This comparison helps detect peripheral artery disease (PAD), a condition where arteries in the limbs narrow, reducing blood flow.

The procedure involves measuring systolic blood pressure at the ankle using a Doppler ultrasound device and a blood pressure cuff. The measurement is then repeated at the same time on the upper arm (brachial artery). The ABI is calculated by dividing the ankle systolic pressure by the brachial systolic pressure. A normal ABI is typically between 0.9 and 1.3. An ABI below 0.9 suggests PAD, while an ABI above 1.3 may indicate calcified or hardened arteries, which can also be a sign of PAD or other vascular issues.

The nilkkaolkavarsimittaus is a quick and painless test, usually performed in a doctor's office or a specialized vascular laboratory. It is a valuable tool for identifying individuals at risk for PAD, which can lead to significant morbidity and mortality if left untreated. Early detection through ABI measurement allows for timely intervention, such as lifestyle modifications, medication, or revascularization procedures, to improve circulation and reduce the risk of complications like claudication, critical limb ischemia, and amputation.
