The Zenith Dissection Endovascular System is a device designed for treatment of aortic type B dissection utilizing the Provisional ExTension to Induce COmplete ATtachment (PETTICOAT) technique. Due to the stent design (low radial force and lack of columnar support), significant risk of stent misalignment exists, which we have encountered in four out of 25 patients treated since 2005. Misalignment may result from excessive manipulation of the delivery system at the time of implantation or during catheter manipulation during adjunctive or secondary procedures. The manufacturer has modified the design of this device in order to prevent misalignment, although no serious clinical consequences of this misalignment have been reported with a mean follow-up of 50 months. Care with catheter manipulation after device deployment and accurate review of postoperative imaging are still warranted.
Zenith dissection 血管内系统是一种用于治疗 B 型主动脉夹层的设备，采用临时性延伸以诱导完全贴合技术（PETTICOAT）。由于支架设计（低径向力和缺乏柱状支撑），存在明显的支架错位风险，我们在 2005 年以来治疗的 25 名患者中有 4 名遇到了这种情况。错位可能是由于在植入时过度操作输送系统或在辅助或二次手术中导管操作时引起的。制造商已经修改了该设备的设计以防止错位，尽管在平均 50 个月的随访中没有报告这种错位的严重临床后果。在设备部署后仍然需要小心导管操作，并准确审查术后影像学检查。
