烟囱技术是重建分支动脉的主动脉夹层腔内治疗辅助技术.主动脉弓部分支动脉位于腔内治疗近端锚定区是采用烟囱技术的手术指征.目前的主动脉覆膜支架产品均可用于烟囱技术,但建议选择覆膜支架重建分支动脉.主动脉支架和分支动脉支架推荐的直径放大率分别为15％和5％,相互重叠长度需＞2 cm.Ⅰa型内漏是烟囱技术最重要的并发症,适当的支架直径选择和重叠长度及球囊扩张技术能有效降低其发生率.术后长期抗凝治疗能有效预防分支支架狭窄发生.

Chimney technique is an assistive technology of endovascular aortic repair, which is used to reconstruct the vital branch vessel invaded by aortic pathology.In chimney technique, most of the commercial aortic stent-graft can be used, and covered branch stent-graft is recommended to decrease the risk of type Ⅰ a endoleak.The suggested oversizing for aortic stent-graft and branch stent-graft is 15％ and 5％ respectively, and the length of overlapping between stent-grafts should be more than 2 cm.Type Ⅰ a endoleak is the main concentration, appropriated oversizing and overlapping are important precautions theoretically.Anticoagulation therapy post-operation is crucial in preventing restenosis of the chimney stentgraft.
