No-reflow phenomenon.
To the Editor: In reviewing no-reflow, Rezkalla and Kloner1 indicted injuryinduced microvascular changes, but did not mention spasm of resistance vessels, which might be the basic mechanism of no-reflow. I proposed in 1971 that no-reflow (“stasis”) is due to ischemic injury-induced spasm, and the evidence seemed convincing.2 Short coronary occlusions reversed no-reflow, and this was interpreted...
متن کامل'No-reflow' phenomenon.
A 57-year-old man presented with new anginal symptoms nine years after three-vessel coronary artery bypass grafting. Cardiac catherization revealed severely and diffusely diseased saphenous vein graft to the obtuse marginal coronary artery. Percutaneous coronary intervention was complicated by the ‘no-reflow’ phenomenon. The patient suffered a periprocedural myocardial infarction (peak troponin...
متن کاملNo-reflow phenomenon.
Because total coronary artery occlusion was found in the early hours of transmural myocardial infarction, most of our research interest and treatment strategies focus on epicardial coronary arteries.1 Little attention, however, is paid to the coronary microvasculature. When a coronary artery is occluded, detrimental changes occur in the cardiac capillaries and arterioles. After relief of the oc...
متن کاملManagement of the no-reflow phenomenon.
The lack of reperfusion of myocardium after prolonged ischaemia that may occur despite opening of the infarct-related artery is termed "no reflow". No reflow or slow flow occurs in 3-4% of all percutaneous coronary interventions, and is most common after emergency revascularization for acute myocardial infarction. In this setting no reflow is reported to occur in 30% to 40% of interventions whe...
متن کاملAttenuation of no-reflow phenomenon, neutrophil activation, and reperfusion injury in intestinal microcirculation by topical adenosine.
Small mesenteric arteries supplying partially isolated jejunal segments were totally occluded for 5 minutes and then released. With video microscopy, blood flow was calculated from measurements of submucosal arteriolar diameter and red blood cell velocity. For the first 30 minutes of reperfusion, the serosa was superfused with a Ringer's vehicle containing either adenosine (ADO; 10(-4) M), acet...
