introduction: in the absence of microvascular replantation or in crash injury cases in which obtaining an acceptable function is not possible, amputation of the injured finger seems to be the best treatment modality. some studies recommended leech therapy for this kind of injury after vascular repair to decrease venous congestion. case presentation: in this case report, the authors presented a ...

BACKGROUND Myocardial perfusion during adenosine-induced hyperemia is used both in clinical diagnosis of coronary heart disease and for scientific investigations of the myocardial microcirculation. The objective of this study was to clarify whether adenosine-induced hyperemia is dependent on endothelial NO production or is influenced by adrenergic mechanisms. METHODS AND RESULTS In 12 healthy...

OBJECTIVE To investigate the effects of pressure relief magnitude on heel blood hyperemia in persons with and without diabetes mellitus. DESIGN Study participants (1 group of persons with diabetes and 1 group without diabetes) lay on a support surface for 70 minutes with 1 heel on an end cell of a support surface. Cell pressure was computer controlled to be 20 mm Hg during support and 5 or 0 ...

PURPOSE To evaluate conjunctival hyperemia associated with bimatoprost 0.01% treatment in patients who replace latanoprost 0.005% with bimatoprost 0.01%. METHODS Randomized, double-masked, vehicle-controlled, multicenter study of patients with ocular hypertension or glaucoma whose intraocular pressure (IOP) was adequately controlled on latanoprost monotherapy. At baseline, patients discontinu...

STUDY DESIGN Cross-sectional observational study. OBJECTIVES To investigate the presence of soft tissue hyperemia in plantar fasciitis with power Doppler ultrasound. BACKGROUND Localized hyperemia is an established feature of tendinopathy, suggesting that neurovascular in-growth may contribute to tendon-associated pain in some patients. The presence of abnormal soft tissue vascularity can b...

Our aim was to elucidate the site and mechanism responsible for reactive hyperemia in coronary circulation. In in vivo beating canine hearts, microvessels of the left anterior descending coronary artery (LAD) were observed through a microscope equipped with a floating objective. Flow velocity of the LAD was measured with a suction-type Doppler probe. The LAD was occluded for 20 or 30 seconds an...

Until now, peripheral vascular endothelial function testing has been performed in research laboratories under highly controlled conditions, thus limiting its clinical applicability. In this study, we evaluated endothelial function in two peripheral vascular beds before and during reactive hyperemia in an outpatient clinic setting. The brachial artery was imaged with a portable ultrasound device...

Peripheral arterial flow has been assessed for a variety of indications including characterization of endothelial function during reactive hyperemia. However, quantification of this blood flow as a surrogate remains an imperfect reflection of endothelial function. We sought to better characterize hyperemic reaction to (1) elucidate the influence of the endothelial function and (2) assess the re...
