Castor单分支支架系统与烟囱支架技术治疗累及左锁骨下动脉的B型主动脉夹层早期疗效对比
Early outcomes of Castor single-branch stent versus chimney technique for type B aortic dissection with left subclavian artery involvement
目的 比较Castor单分支支架系统与烟囱支架技术在累及左锁骨下动脉(LSA)的Stanford B型主动脉夹层(TBAD)腔内修复术中的早期临床应用效果。 方法 选取2021年5月—2024年5月在唐山市工人医院诊治的83例累及LSA的TBAD患者作为研究对象,按手术方式分为对照组(42例,接受烟囱支架技术)与观察组(41例,接受Castor单分支支架系统)。比较两组手术相关指标、LSA通畅率、主动脉重塑效果指标及围手术期并发症。 结果 观察组的手术时间、透视时间均长于对照组(P <0.05)。观察组与对照组住院时间比较,差异无统计学意义(P >0.05)。两组住院期间LSA通畅率均为100.00%。随访1年,两组LSA通畅率比较,差异无统计学意义(P >0.05)。观察组与对照组夹层真腔和假腔直径比较, 结果 ①不同时间点真腔和假腔直径比较,差异均有统计学意义(P <0.05);②观察组与对照组真腔和假腔直径比较,差异均有统计学意义(P <0.05),观察组术后真腔直径更大、假腔直径更小,腔内修复效果更佳;③两组真腔和假腔直径变化趋势比较,差异均有统计学意义(P <0.05)。观察组假腔血栓化率高于对照组(P <0.05)。观察组Ⅰ型内漏率低于对照组(P <0.05)。观察组与对照组脑卒中率和脊髓缺血率比较,差异均无统计学意义(P >0.05)。 结论 Castor单分支支架治疗累及LSA的TBAD,虽延长手术及透视时间,但可显著降低Ⅰ型内漏风险,促进假腔血栓化与主动脉重塑,且不影响LSA远期通畅率,早期安全性和有效性均良好。
Objective To compare the early clinical outcomes of the Castor single-branch stent graft system and the chimney stent technique in thoracic endovascular aortic repair (TEVAR) for Stanford type B aortic dissection (TBAD) involving the left subclavian artery (LSA). Methods A total of 83 patients with TBAD involving the LSA, admitted between May 2021 and May 2024, were included. Patients were divided according to surgical technique into the control group (n = 42, chimney stent technique) and the observation group (n = 41, Castor single-branch stent graft). Perioperative indicators, LSA patency, aortic remodeling outcomes, and complication rates were compared between the two groups. Results The operation time and fluoroscopy time in the observation group were significantly longer than those in the control group (P < 0.05). No statistically significant difference was found in the length of hospital stay between the two groups (P > 0.05). The LSA patency rate was 100.00% in both groups during hospitalization, and no significant difference was observed between the two groups at the 1-year follow-up (P > 0.05). Comparison of true lumen and false lumen diameters between the two groups revealed: (1) significant differences at different time points (P < 0.05); (2) significant differences between the observation and control groups (P < 0.05), with the observation group exhibiting a larger postoperative true lumen diameter and a smaller false lumen diameter, indicating superior endovascular repair outcomes; (3) significant differences in the trends of diameter changes between the two groups (P < 0.05). The false lumen thrombosis rate was significantly higher in the observation group than in the control group (P < 0.05). The incidence of type I endoleak was significantly lower in the observation group than in the control group (P < 0.05). No statistically significant differences were found in the rates of stroke or spinal cord ischemia between the two groups (P > 0.05). Conclusion The Castor single-branch stent graft, while prolonging operation and fluoroscopy time, significantly reduces the risk of type I endoleak, promotes false lumen thrombosis and favorable aortic remodeling, and maintains long-term LSA patency. It demonstrates favorable early safety and efficacy.
