Abstract:
Objective To investigate the effect and safety of Guard wire technology in percutaneous coronary intervention( PCI) of ostial lesions and the treatment of passing ostial lesions. Methods Thirty?five cases patients needing PCI of ostial lesions were selected and divide randomly in to A group(n=18) and B group(n=17) . A group used Guard wire technology and B group used common method. The X?ray exposure time,complications,the amount of contrast agents of two groups were analyzed. Forty?six cases patients needing the treatment of passing ostial lesions were divided randomly into C group( n=25) and D group( n=21) . C group used Guard wire technology and D group used common method. Complications of two groups were investigated. Results The X?ray exposure time, the amount of contrast agents and complications of A group were fewer than that of B group,the difference were significant((5. 7±0. 6) min vs. (9. 3±1. 1) min,(84. 3 ±6. 4) ml vs. (94. 1±10. 0) ml,6%(1/18) vs. 35%(6/17);t or χ2=-11. 80,-3. 50,4. 80;P<0. 05). The complications of C group was lower than that of D group,and the difference was significant( 4%( 1/25) vs. 29%( 6/21);χ2=5. 30,P<0. 05) . Conclusion Guard wire technology is safe and useful in percutaneous coronary intervention of ostial lesions and the treatment of passing ostial lesions,and it is feasible in clinical practice.
