title: [Retrograde recanalization of coronary artery occlusions: novel method for increase of the rate of successful interventions].
abstract: First results of the use of a novel method of percutaneous coronary angioplasty of chronic occlusions of coronary arteries are presented. In 8 patients (men aged 54 - 75 years, mean age 60,4 +/- 7.1 years, mean duration of occlusion 45.5 +/- 7.9 months) retrograde recanalization was carried out through collateral branches of right coronary artery (RCA, 6 patients) or left anterior interventricular artery (LAIA, 2 patients). In all cases the procedure was preceded by unsuccessful attempts of antegrade recanalization of occlusion. Retrograde intervention was successful in 6 of 8 cases (5 RCA, 1 - LAIA). Technique of retrograde recanalization is described, criteria of selection of collateral branch, and instrumentation for optimization of the method are presented. As collateral branch in 6 cases we used septal branches either from LAIA (in case of recanalization of RCA) or from posterior interventricular branch of RCA (intervention on LAIA). In 2 cases retrograde recanalization of RCA was performed through posterior-lateral collateral branch of the circumflex artery.
