Objective A retrospective analysis on the use of DK crush and SBSK crush technology to deal with bifurcation lesions and to investigate the reliability and efficacy of the SBSK (single balloon single kissing) crush technology.
Methods 56 cases of hospitalised patients undergoing percutaneous coronary intervention (PCI) were admitted in the Second Hospital of Shanxi Medical University from June 2005 to September 2012, including 40 cases of male and 16 cases of, age 63 ± 11 There were 26 patients in which DK crush technique was used to complete the double bifurcation lesion stenting (DK Group), of which, lesions of 18 cases were the left anterior descending (LAD) + D1, 6 cases were circumflex artery + OM, 2 cases were right coronary artery + obtuse marginal branch.. There were 30 patients in which SBSK crush technique was used to complete the double bifurcation lesion stenting group (SBSK Group). Of the 30 patients, including 22 males and 10 females, age 43 to 78, there were 12 cases with acute myocardial infarction in the recovery period and 18 cases with unstable angina. Lesions: These 30 patients with coronary disease are true bifurcation lesions in line with the Lefevre taxonomy branch vessel diameter > 2.0mm. in which, lesions of 22 cases were the left anterior descending (LAD) + D1, 6 cases were circumflex artery +OM, 2 cases were right coronary artery + obtuse marginal branch.
Results 2 patients did not complete the final kiss expansion. In the DK group; the completion rate was 92.3%. 2 patients did not complete the final kiss expansion in SBSK group; the completion rate was 93.3%. The difference between the two groups was not statisticallysignificant. The mean time of guide wire through the stent mesh into the branch was 6 ± 4.6min after stenting main branch in SBSK group. The mean PCI total time was 38 ± 19 min. The mean total contrast agent volume was 90 ± 60ml. In DK group, due to the earlier completion without making related statistics.
Conclusions SBSK crush and DK crush technology can obtain a high and eventually kissing expansion rate. SBSK crush is easier to operate, it is possible to further shorten the time of PCI and reduce the use of contrast agents.
