Anatomic variations, calcified, tortuous, angulated lesions, and lack of support to increase the complexity of transradial intervention (TRI). Guidezilla is a mother-and-child catheter enabling increased support during complex interventions. As there are few published reports of its use, we describe our experience using this device to assist TRI in Chinese patients. The aim of this study was to investigate the efficacy and safety of the Guidezilla guide extension catheter in complex coronary interventions. Thirty-two patients' clinical characteristics, angiographic details, and in-hospital outcome retrospectively collected between June 2015 and August 2017. Patients were 59.44 ± 10.48 years of age and 26 (81%) were men. The most frequent target vessels were the RCA (34%) and LAD (31%), patients had complex type C (53%) or B (47%) lesions, severely tortuous (41%) and angulated (22%).With the use of Guidezilla, technique success was 100%, and procedural success was 94%. The mean diameter of the deployed stents was 2.97 ± 0.37 mm, and the length was 27.19 ± 8.14 mm. The estimated mean distance of Guidezilla intubation into the target vessel was 7.66 ± 2.29 cm.The Guidezilla catheter extension safely facilitated successful completion of TRI in complex coronary artery lesions. This device can help interventionalists successfully perform difficult procedures.
解剖变异、钙化、迂曲、成角病变以及缺乏支撑，增加了经桡动脉介入治疗（TRI）的复杂性。Guidezilla 是一种子母导管，可在复杂介入治疗中提供更多的支撑。由于其使用的相关报道较少，我们描述了我们使用该设备辅助中国患者进行 TRI 的经验。本研究旨在探讨 Guidezilla 导引导管延长导管在复杂冠状动脉介入治疗中的疗效和安全性。回顾性收集了 2015 年 6 月至 2017 年 8 月期间 32 例患者的临床特征、血管造影细节和住院结局。患者年龄为 59.44 ± 10.48 岁，26 例（81%）为男性。最常见的靶血管为 RCA（34%）和 LAD（31%），患者病变类型为复杂 C 型（53%）或 B 型（47%），迂曲（41%）和成角（22%）严重。使用 Guidezilla 后，技术成功率为 100%，手术成功率为 94%。植入支架的平均直径为 2.97 ± 0.37mm，长度为 27.19 ± 8.14mm。Guidezilla 导管延长段进入靶血管的估计平均距离为 7.66 ± 2.29cm。Guidezilla 导管延长段安全地促进了复杂冠状动脉病变的 TRI 顺利完成。该设备可帮助介入治疗师成功完成困难的手术。
