No - Reflow
A. DEFINITION. The no-reflow phenomenon was originally observed in experimental models of acute myocardial infarction (MI) and was described as a failure to restore normal myocardial blood flow despite removal of the coronary obstruction. Since that time, no-reflow has been shown to complicate thrombolytic therapy and percutaneous revascularization with PTCA and other devices. Defined angiograp...
متن کاملCapillary pericytes mediate coronary no-reflow after myocardial ischaemia
After cardiac ischaemia, a prolonged decrease of coronary microvascular perfusion often occurs even after flow is restored in an upstream artery. This 'no-reflow' phenomenon worsens patient prognosis. In the brain, after stroke, a similar post-ischaemic 'no-reflow' has been attributed to capillary constriction by contractile pericytes. We now show that occlusion of a rat coronary artery, follow...
متن کاملCase Report A Practical Method for No-Reflow Treatment
No-reflow is an undesirable result of percutaneous coronary interventions (PCI) [1]. Intracoronary (IC) vasodilators such as verapamil, nitroprusside, or adenosine are being administered for the treatment of no-reflow via the guiding catheter [2], but sometimes distal flow restoration is not satisfactory especially in patients with TIMI 0 flow. Vasoactive drug administration at the distal part ...
متن کاملThe no reflow phenomenon in the coronary arteries.
In the last twenty years, the treatment of coronary heart disease with cardiac catheterization has greatly advanced. This therapeutic approach has had unexpected side effects, however, for which solutions must be found, particularly in the are of interventional cardiology. The “noreflow” phenomenon, a side effect, is an uncommon and critical occurrence and, if not reversed, causes a high rate o...
متن کاملPredicting the no-reflow phenomenon following successful percutaneous coronary intervention.
In the setting of acute myocardial infarction, early and adequate reopening of an infarct-related artery is not necessarily followed by a complete restoration of myocardial perfusion. This condition is usually defined as 'no-reflow'. The pathophysiology of no-reflow is multifactorial since extravascular compression, microvascular vasoconstriction, embolization during percutaneous coronary inter...
