[Coronary microvascular obstruction phenomenon after endovascular recanalization in patients with chronic coronary...

The article analyzed no-reflow phenomenon after endovascular recanalization for chronic coronary occlusion. An assessment of antegrade blood flow was made while performing the coronary angiography according to TIMI classification. The Rentrop scale was used for evaluation of retrograde blood flow. The results of investigation showed, that the frequency of occurrence of no-reflow phenomenon after endovascular recanalization in the case of chronic coronary occlusion wasn't higher than 5%. The onset of no-reflow phenomenon after endovascular recanalization in chronic coronary occlusion doesn't depend on the volume of retrograde collateral filling of distal coronary bloodstream. A postponed restoration of antegrade blood flow was possible in patients with previously manifested (Rentrop II-III) retrograde collateral filling of periphery.
