| Objective To compare the effect of jailed balloon technique and double guide wire technique on branch opening protection in the treatment of coronary bifurcation disease. Methods Eighty-one patients with coronary bifurcation lesions diagnosed by coronary angiography from Sept 2010 to May 2016 in our hospital were selected and randomized into two groups. Double guide wire technique group (40 cases) was treated with double guide wire technique, and the application of Rewire guide wire was determined according to the blood flow condition of the side branch after the release of single stent. The jailed balloon technique group (41 cases) used small bore balloon to protect branch opening, and the side branch balloon would expand the protection when the main branch was released, then the flow of the branch was observed after the implantation of stent. The difference between the two groups was compared with respect to the time of percutaneous coronary intervention, the rate of occlusion, the time of exposure, the dosage of contrast agent, the cost of operation, the major adverse cardiovascular events after the operation, the quantitative analysis of coronary angiography and so on. Results The number of side branch occlusion in double guide wire group and the balloon group was 10 and 2 respectively, and the difference was statistically significant(P<0.05). Compared with double guide wire technique group, the time of PCI and exposure were shorter, the dosage of contrast medium was less, and the cost of operation was lower in jailed balloon technique group, and the difference was statistically significant (P<0.05). There was no significant difference in the incidence of MACE and QCA between the two groups during the one year follow-up (P> 0.05). Conclusion Jailed balloon technique can protect the branch opening, reduce the occlusion rate of side branches, and reduce the cost of operation in the treatment of coronary artery, and it is worth promotion. |
