Blood flow in the perimalleolar skin in relation to posture in patients with venous hypertension.
The resting and standing perimalleolar skin blood flow and venoarteriolar response have been studied in 20 patients with postphlebitic limbs and 25 normal volunteers using laser-Doppler flowmetry. In postphlebitic limbs the venoarteriolar reflex was impaired and both the resting and standing skin blood flow were increased, suggesting the presence of local vasoparalysis similar to that previously observed in diabetics with peripheral neuropathy.
