Regardless of the clinical setting, a good back-up represents one of the most important conditions to ensure guide wire and balloon advancement and stent delivery. As a "mother and child" system, the GuideLiner catheter (Vascular Solutions Inc., Minneapolis, MN, USA) provides an extension to the guide catheter with better coaxial alignment and stability. We report two didactic cases showing the usefulness of the GuideLiner device in everyday catheterization laboratory practice. The first case was a primary percutaneous coronary intervention (PCI) in a 71-year-old diabetic man admitted for inferior ST-elevation myocardial infarction, related to tight proximal stenosis in a dominant tortuous and calcified left circumflex. The second case was an elective PCI in a 76-year-old man admitted for stable angina (Canadian Cardiovascular Society [CCS] class III), related to focal intra-stent restenosis of a saphenous venous graft to the left anterior descending. In both cases, the GuideLiner catheter provided a good back-up insuring the success of PCI and drug-eluting stents implantation, with a good in-hospital outcome.
无论临床情况如何，良好的支撑是确保导丝、球囊推进以及支架输送的最重要条件之一。作为一种“子母”系统，GuideLiner导管（美国明尼阿波利斯市血管解决方案公司）为引导导管提供了延伸，具有更好的同轴对准性和稳定性。我们报告两例示教病例，展示了GuideLiner装置在日常导管实验室操作中的实用性。第一例是一名71岁糖尿病男性因下壁ST段抬高型心肌梗死入院接受的直接经皮冠状动脉介入治疗（PCI），病变为优势型迂曲钙化左旋支近端严重狭窄。第二例是一名76岁男性因稳定型心绞痛（加拿大心血管学会[CCS]Ⅲ级）入院接受的择期PCI，病变为左前降支大隐静脉桥血管支架内局灶性再狭窄。在这两例病例中，GuideLiner导管都提供了良好的支撑，确保了PCI和药物洗脱支架植入的成功，并取得了良好的院内治疗效果。
