Abstract
Objective To explore the clinical value of implanting a DES (drug eluting stent)in main vessel and dilating a small external diameter balloon in side branch in treating coronary bifurcation lesion. Methods Forty-eight patients who underwent this intervention strategy were retrospectively observed to study its short-term effectiveness and safety. Results The angiographic effectiveness was as follow: Before the operation the degree of main vessel’s stenosis was (86.80%±9.10%), while the degree of main vessel’s stenosis was (0.20%±0.80%) after the operation (Z=-6.08,P<0.01). Before the operation the degree of side branch’s stenosis was (67.10%±20.00%), while the degree of side branch stenosis was (27.30%±18.20%) after the operation (Z=-5.99, P<0.01). The clinical effectiveness was as follow: No MACEs happened during the operation in this study. The safety was as follow: When the main vessel sent balloon was dilated in (15.10±1.80) atm and the side branch small balloon was dilated in (10.00±2.70) atm, the jailed small balloon and guide-wire in the side branch could be removed smoothly. Conclusion The instant effectiveness and safety of implanting a DES in main vessel and dilating a small balloon in side branch in treating coronary bifurcation lesion is good. But its long-term effectiveness and safety is worth studying further.
