[Clinical, angiographical, and procedural causes of acute vessel closure during transluminal coronary intervention].
OBJECTIVE
To elucidate factors related to acute vessel closure (AVC) after transluminal coronary intervention.


METHODS
From population of 10439 patients subjected to transluminal coronary intervention 2 groups were formed: with (n=885) and without (n=885) acute vessel closure (AVC). Twenty five clinical, angiographical and procedural characteristics of patients of these 2 groups were included into mono and multifactorial logistic regression analysis.


CONCLUSIONS
The following factors were univariate predictors of acute vessel closure: smoking [odds ratio (OR) 1.42], unstable angina (OR=2.130, acute myocardial infarction within previous 24 hours (OR 2.76), cardiogenic shock (OR 4.31), urgent procedure (OR 1.94), eccentric stenosis (OR 1.67), calcified lesion (OR 2.21), preexisting thrombosis (OR 3.79), lacerated complicated stenosis (OR 2.02), tortuous lesion (OR 1.35), low operator experience (OR 3.37), balloon angioplasty as sole procedure (OR 1.66), concomitant rheolytic thrombectomy (OR 1.95), urgent stenting (OR 1.45). Elective stenting significantly lowered risk of acute vessel thrombosis. Multifactorial step-up analysis selected the following independent predictors of AVC: smoking, acute myocardial infarction within previous 24 hours, cardiogenic shock, preexisting thrombosis, lacerated complicated stenosis, and concomitant rheolytic thrombus extraction. Thus only elective stenting significantly reduced risk of AVC.
