Segmental Pressures

Segmental Pressure studies are performed using the same method as an Ankle Brachial Index but incorporate additional pressure cuffs wrapped at various positions on the leg. Sites typically include the ankle, above and below the knee and the high thigh.

Using a noninvasive vascular Doppler, pressures are taken at both arms, and at each position on the legs by inflating the pressure cuffs past the point where Doppler sounds cease, then slowly deflating the cuffs until Doppler sounds return.

Segmental Pressures are used to evaluate blood flow and identify the location of blockages in the arteries of the leg by observing pressure differences between adjacent cuff sites.

Pressure differences between two adjacent levels of less than 20 mmHg are generally considered normal.¹
