A case of coronary chronic total occlusion with long calcification treated by intravascular lithotripsy

摘要: 1例回旋支慢性完全闭塞病例，通过冠状动脉造影及血管内超声证实伴有长钙化及深层钙化。导丝通过闭塞段后，棘突球囊不能充分扩张。通过Pull-Back冲击波球囊多次串联定位分段处理病变，有效优化了长钙化伴深层钙化病变的预处理，使手术顺利完成，且无并发症发生。Abstract: A case of chronic total occlusion of the left circumflex artery with extensive and deep calcification was confirmed by coronary angiography and intravascular ultrasound. None of the Lacrosse non-slip elements (NSE) were adequately dilated after the guide-wire passed through the occluded segment. However, multiple tandem localization of segmented lesions using Pull-Back shockwave balloon effectively optimized the pre-treatment of long and deep calcification lesions, ensuring that the surgery was completed successfully and without any complications.
