Augmentation of blood flow in limbs with occlusive arterial disease by intermittent calf compression

摘要: Abstract Purpose: This study was designed to investigate the effect of intermittent calf compression on popliteal arterial blood flow and see how is influenced by position subject pressure at ankle. Methods: Volume in artery subjects sitting prone positions measured with duplex ultrasonography before inflation immediately after deflation a pneumatic cuff placed around calf. Eleven legs control 41 patients symptoms (32% diabetes) decreased ankle were studied. Cuffs inflated for 2 seconds pressures ranging from 20 120 mm Hg. Results: An increase two eight times (mean 4.4 ± 2.0) found seated subjects. Little change observed when position. In obstruction, mean 3.2 1.6 resting flow. correlation between maximum ankle/brachial index. Conclusions: increased arteriovenous gradient accounts some but not all increase, much which must be attributable transient vasodilatation. Because does depend an inflow adversely affected low ankle-brachial index or toe-pressure, external limb may deserve investigation as possible adjunct nonoperative treatment severe insufficiency.
