Vascular laboratory criteria for the management of peripheral vascular disease of the lower extremities.
From experience gained in over 4,500 vascular laboratory procedures, segmental Pulse Volume Recorder (PVR) tracings, systolic pressure measurements, and other noninvasive laboratory techniques have been found extremely useful in the management of patients with arteriosclerotic peripheral vascular disease. Both PVR recordings and limb pressures were found to be important and are used in complementary fashion. Although arteriography is essential in defining structural lesions and in establishing graftability, noninvasive vascular studies provide an inexpensive, accurate, reproducible method for assessing functional significance of arterial disease. These studies contribute to the diagnosis, definition of severity, and establishment of an objective baseline prior to medical or surgical therapy. Because they may be used in a repetitive manner, they are extremely useful in establishing success of a given therapy and in the long-term follow-up of patients. Based upon our experience, laboratory criteria have been developed which allow accurate identification of ischemic rest pain, aid in predicting healing of foot lesions or below-knee amputations, and quantitate the functional disability of claudication.
