title: [Clinical practice and thinking on chimney technique for endovascular aortic repair].
abstract: 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 stent-graft.
