Objective: To preliminarily investigate effectiveness and safety of sutureless integrated stented graft (SIS graft) on aortic dissection patients undergoing surgeries. Methods: In October 2019, 2 patients with aortic dissection were treated by SIS graft in Shenzhen Fuwai Hospital. Data of the operations and follow-up were recorded. Results: Patient 1 (male, 42 years old) was treated with aortic sinus repair, ascending aortic replacement, total arch replacement combined with frozen elephant trunk implantation. Time of cardiopulmonary bypass and circulatory arrest was 81 minutes and 9.5 minutes,respectively. The lowest nasopharynx temperature was 27.3 ℃. This patient was followed up for 10 months and no postoperative complication was found. Six-month postoperative aortic CT angiography (CTA) revealed SIS graft was patent and no anastomosis fistula or stent leakage occurred. True lumen of stented area was full-filled and false lumen disappeared. Incomplete false lumen thrombosis was seen in un-stented thoracic aorta, but no progressive aortic enlargement appeared. Patient 2 (male, 61 years old) was treated with ascending aortic replacement, ascending aorta to right femoral artery bypass graft, total arch replacement combined with frozen elephant trunk implantation. Time of cardiopulmonary bypass and circulatory arrest was 77 minutes and 7 minutes,respectively. The lowest nasopharynx temperature was 27.3 ℃. This patient was also followed up for 10 months and was free of postoperative complications. Six-month postoperative aortic CTA revealed SIS graft was patent and there was no anastomosis fistula or stent leakage. Perfusion of true lumen in thoracic aorta and branches of abdominal aorta improved significantly and complete false lumen thrombosis could be seen in thoracic aorta. Progressive aortic enlargement was not detected. Conclusion: Application of SIS graft can reduce circulatory arrest time and avoid deep hypothermia, which will decrease risks of postoperative complications, and this graft can simplify surgery procedure. However, further clinical trial for effectiveness and safety of SIS graft should be applied.
目的： 初步探索一体化免缝合带支架人工血管系统应用于主动脉夹层患者手术治疗的有效性与安全性。 方法： 2019年10月中国医学科学院阜外医院深圳医院采用一体化免缝合带支架人工血管系统完成2例主动脉夹层患者的手术治疗。记录手术相关数据、术后随访结果。 结果： 患者1，男，42岁，行主动脉窦成型+升主动脉替换+全主动脉弓替换+降主动脉支架象鼻置入术，体外循环时间81 min，停循环时间9.5 min，最低鼻咽温27.3 ℃。术后10个月随访无并发症发生，术后半年复查主动脉CT血管造影（CTA）提示：人工血管血流通畅，未见吻合口瘘、支架内漏，降主动脉支架段真腔完全充盈，假腔消失，远端假腔部分血栓化，未见管腔扩张。患者2，男，61岁，行升主动脉替换+全主动脉弓替换+降主动脉支架象鼻置入+升主动脉-右股动脉搭桥术，体外循环时间77 min，停循环时间7 min，最低鼻咽温27.3 ℃。术后10个月随访无并发症发生，术后半年复查主动脉CTA提示：人工血管血流通畅，未见吻合口瘘、支架内漏，降主动脉真腔及腹主动脉分支充盈较术前明显改善，降主动脉假腔完全血栓化，全胸腹段主动脉较术前无扩张。 结论： 对于主动脉夹层患者一体化免缝合带支架人工血管系统可缩短手术停循环时间，避免深低温，降低并发症风险，同时可降低手术操作难度，但其安全性与有效性仍需进一步探索。.
