No-Reflow Phenomenon in Central Retinal Artery Occlusion: Incidence, Risk Factors, and Clinical Implications
PURPOSE To investigate the incidence and risk factors of the no-reflow phenomenon in central retinal artery occlusion (CRAO) patients and to determine its effects on visual and anatomic outcomes. METHODS In 102 eyes with CRAO in which arterial recanalization was obtained within 1 week from baseline, fluorescein angiography images obtained at baseline and 1 week were retrospectively reviewed. ...

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...

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 کاملCentral Retinal Artery Occlusion Masquerading as Branch Retinal Artery Occlusion
Dear Editor, Retinal artery occlusion (RAO) is characterized by attenuated arterioles and ischemic retinal opacity, which suggest retinal infarction. Branch RAO (BRAO) has a more favorable prognosis than central RAO (CRAO). CRAO and BRAO can be differentiated based on the isch-emic retinal opacity area, location of the attenuated vessels , and a cherry-red spot [1]. However, we encountered a ca...

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...
