A triple-coaxial (triaxial) system, which consists of a small microcatheter, a large microcatheter, and a 4-Fr. catheter, has been reported to allow super-selective catheterization. A 1.6-Fr. microcatheter has recently become available as the small microcatheter for the triaxial system, in addition to 0.014-in. pushable bare platinum coils that may be introduced into the 1.6-Fr. microcatheter.
The purpose of the present study was to evaluate the feasibility of 0.014-in. pushable bare platinum coils in embolization through the 1.6-Fr. microcatheter of the triaxial system.
Between November 2015 and October 2019, 19 embolizations were performed on 18 patients, 9 males and 9 females with a median age of 77 years (range, 41-88 years), using 0.014-in. pushable bare platinum coils through the 1.6-Fr. microcatheter of the triaxial system. The technical success rate, clinical success rate, and complications associated with the procedure were assessed. Technical success was defined as the successful delivery and placement of 0.014-in. pushable bare platinum coils, and clinical success as the immediate postembolic complete cessation of blood flow confirmed by digital subtraction angiography.
Eighty-four 0.014-in. pushable bare platinum coils were delivered and 19 arteries were successfully embolized. The median number of 0.014-in. pushable bare platinum coils was 4 (range, 1-12). The technical success rate was 100% (84/84) and the clinical success rate was also 100% (19/19). There were no complications associated with the procedures.
The use of 0.014-in. pushable bare platinum coils in super-selective embolization through the 1.6-Fr. microcatheter of the triaxial system appears to be feasible and safe.
据报道，一种由小型微导管、大型微导管和4F导管组成的三同轴系统可实现超选择性导管插入术。除了可引入1.6F微导管的0.014英寸可推送裸铂金线圈外，1.6F微导管最近也作为三同轴系统的小型微导管投入使用。
本研究旨在评估0.014英寸可推送裸铂金线圈通过三同轴系统的1.6F微导管进行栓塞的可行性。
2015年11月至2019年10月期间，对18例患者（9例男性，9例女性，中位年龄77岁，范围41 - 88岁）进行了19次栓塞治疗，使用0.014英寸可推送裸铂金线圈通过三同轴系统的1.6F微导管。评估了技术成功率、临床成功率以及与该操作相关的并发症。技术成功定义为0.014英寸可推送裸铂金线圈成功输送和放置，临床成功定义为数字减影血管造影证实栓塞后立即完全停止血流。
共输送了84个0.014英寸可推送裸铂金线圈，成功栓塞了19条动脉。输送的0.014英寸可推送裸铂金线圈的中位数为4个（范围1 - 12个）。技术成功率为100%（84/84），临床成功率也为100%（19/19）。该操作未出现并发症。
在通过三同轴系统的1.6F微导管进行超选择性栓塞中使用0.014英寸可推送裸铂金线圈似乎是可行且安全的。
