The calf blood flow at rest and after 3 minutes of circulatory arrest (venous occlusion plethysmography) and the systolic ankle blood pressure (Doppler ultrasound) were measured in the following 5 groups: 13 normotensive subjects without evidence of arterial occlusive disease (group A), 33 normotensive patients with occlusions or stenoses of major leg arteries (group B), 5 patients with hypertension, but without occlusions of the main arteries (group C), 17 patients with hypertension and occlusions of major leg arteries (group D) and 12 patients with coarctation of the thoracic aorta (group E). In group A and B a good correlation between the calf peak flow (PF) and the systolic pressure of the posterior tibial artery (SAP) or the systolic pressure difference between arm and ankle arteries (SPD) was found. In the presence of hypertension (groups C and D) and at a given SAP PF tended to be lower than in the normotensive groups (A and B). The PF in coarctation (group E) reached the values measured in the subjects with patent arteries, whereas SAP and especially SPD showed characteristic changes. The underlying pathophysiologic mechanisms and the practical application of pressure and flow measurements in routine diagnosis and evaluation of peripheral arterial disease are discussed.

    A hydrostatic rise in forearm vascular transmural pressure may be associated with an increase in forearm blood flow (FBF) that causes pain. To test this hypothesis, forearm vascular transmural pressure was elevated in eight male volunteers by a series of 1-min hypobaric exposures of the left arm...
