The diagnosis of aortoiliac disease. A noninvasive femoral cuff technique.

An inexpensive femoral "cuff" developed in this noninvasive vascular laboratory allows pulse volume recordings and systolic pressure measurements of the femoral arteries. Using the parameters 1) femoral/brachial systolic pressure ratio, 2) wave amplitude, and 3) status of the dicrotic notch for assessment of results, it was found that the cuff correctly identified 59 of 62 limbs with at least 50% aortoiliac stenosis, with only two false-positive results, for an accuracy of 97%. The high, wide thigh cuff identified 57 of the 62 limbs, but had 45 false-positive results (77% accuracy). Use of the femoral "cuff" has refined the ability to identify the anatomic location of significant arterial stenoses in the lower extremities.

Femoral artery cuff plethysmography in arterial occlusive disease.

Pulse volume recorder (PVR) measurements are similar to arterial pressure contour tracings and have proved valuable in determining the degree of arterial obstruction in the lower extremity. However, with the standard PVR tracing with thigh, calf, and ankle cuffs, differentiation between high superficial femoral or common femoral artery lesions and combined iliac and superficial femoral artery lesions is extremely difficult. Because the operative approach will vary, depending on whether the disease is primarily in the iliac arteries (and thus intra-abdominal) or in the femoral arteries (and thus extra-abdominal), we have devised a noninvasive method for measuring pressure and flow in the femoral artery with a special cuff. With the addition of the measurement obtained by this method of the standard PVR tracing, the noninvasive differentiation between iliac and high superficial femoral lesions has proved possible.
