Abstract:
Objective:To compare the efficacy and safety of Castor single-branch stent and in vitro fenestration stent in treating thoracic aortic diseases with insufficient landing zone.Methods:The clinical data of patients with thoracic aortic diseases treated with Castor single-branch stent or in vitro fenestrated stent between December 2017 and June 2021 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. A total of 184 patients were included, 99 patients were treated with Castor branch stent, and 85 patients with in vitro fenestration stent. All patients′ general clinical data, surgical data, perioperative and follow-up clinical and imaging data, and postoperative complications were collected. The χ2 test was used to compare the incidence of complications between the two groups, and the Kaplan-Meier method was used to plot the survival rate without adverse events between the two groups. Results:Stent placement was successful in all patients, and the success rate of the technique was 100%. Other branches were reconstructed in 2 patients in the Castor group and double fenestrated stent were reconstructed in 12 patients in the fenestrated group. The mean operation time of the Castor group was significantly shorter than that of the fenestrated group, the number of patients who received local anesthesia was significantly lower than that of the fenestrated group, and the endoleak rate during follow-up was significantly lower than that of the fenestrated group ( P<0.05). There was no significant difference in the postoperative hospital stay, the incidence rate of perioperative complications, mortality, the incidence rate of neurological complications, new dissection or aneurysm rate, branch stent stenosis rate, second surgical intervention rate, and false lumen thrombosis between the two groups ( P>0.05). The adverse event-free survival rate of the Castor group was slightly higher than that of the fenestrated group, but its difference was not statistically significant ( P>0.05). Conclusion:Castor branch stent and in vitro fenestration stent have good short-term and mid-term efficacy in the treatment of aortic diseases with insufficient landing zone, which are safe and effective options for reconstruction of LSA and other branch arteries.
