Abstract:
Objective To observe the efficacy of restrictive bare stent released on the distal end of the trunk of Standford type A aortic dissection. Methods The clinical data of 22 patients with Standford type A aortic dissection requiring aortic arch replacement and trunk surgery and selected for restrictive bare stent placement from November 2016 to February 2018 in our hospital were retrospectively analyzed. Among them, there were 19 males and 3 females, aged 34-68 (49.72±8.05) years. The bare stent was released in the descending thoracic aorta, and the stented elephant trunk was placed in the bare stent. The aortic computerized tomography angiography was reviewed before discharge and the stent position and complications were observed. Results One patient failed to be implanted with bare stents due to a greater resistance and prolapse during implantation. Bare stents were successfully implanted in the remaining 21 patients. One patient died of large-area cerebral infarction after surgery and one patient suffered paraplegia. Twenty patients who survived and successfully implanted bare stents were followed up at regular intervals for 4-21 (13.00±6.14) months. No stroke or death occurred during the follow-up. The computerized tomography angiography showed good stent morphology and position, and no displacement or type Ⅲ endoleak. No stent graft-induced new entry was found. Conclusion As an adjunct to stented elephant trunk, the use of restrictive bare stents can reduce the possibility of recurrence of a distal stent fracture, significantly expand the narrowest segment and true lumen caliber near the endoluminal graft. Aortic remodeling works well.
