目的:总结保留主动脉瓣的根部替换术治疗主动脉根部瘤的临床经验。方法:2017年5月至2019年10月20例主动脉根部瘤患者接受再植法保留主动脉瓣的根部替换术。其中男17例，女3例，年龄(35.6±15.8)岁(12~63岁)。其中马方综合征11例，主动脉瓣二瓣化畸形5例，二次手术1例。术前升主动脉直径(40.6±9.7)mm，主动脉窦直径(52.2±9.2)mm，主动脉瓣环径(27.1±3.6)mm，术前主动脉瓣无反流或轻度反流10例，中度反流5例，重度反流5例。全组患者采用再植法保留主动脉瓣的根部替换术，选择人工血管为：26、28和30 mm直血管(例1、3、6)，26和28 mm带窦人工血管(例4、6)。术中行主动脉瓣成形6例，游离缘折叠4例，钙化清除1例，融合脊切除缝合1例。结果:全部患者无住院死亡，无二次开胸止血。术中体外循环(171.0±25.6)min，阻断(134.0±23.2)min。术后复查主动脉瓣无反流12例，轻度反流8例。随访(15.1±9.8)个月(4~33个月)。随访期间主动脉瓣中度反流2例，余患者为无或少量反流。暂无再次手术患者。1例随访期间出现回旋支栓塞，经保守治疗好转。结论:再植法保留主动脉瓣的根部替换术治疗主动脉根部瘤安全有效，早中期随访结果满意，可以避免抗凝相关并发症，适用于年轻患者。“,”Objective:To summarize our clinical experience in the treatment of aortic root aneurysm by aortic valve sparing root replacement.Methods:From May 2017 to October 2019, a total of 20 patients with aortic root aneurysm underwent aortic valve sparing root replacement by reimplantation method. There were 17 males and 3 females, with an average age of(35.6±15.8) years(12-63 years). There were 11 cases of Marfan syndrome, 5 cases of bicuspid aortic valve, and 1 case of redo operation. The preoperative diameter of ascending aorta was(40.6±9.7)mm, the diameter of aortic sinus was(52.2±9.2)mm, and the diameter of aortic valve ring was(27.1±3.6)mm. There were 10 cases of no or mild regurgitation, 5 cases of moderate regurgitation and 5 cases of severe regurgitation. In the whole group of patients, the root replacement of aortic valve was retained by reimplantation, and the artificial graft were selected as: 26, 28 and 30mm straight vessels, 1, 3 and 6 cases, respectively, 26 and 28mm artificial graft with valsalva sinus, 4 and 6 cases, respectively. During the operation, aortic valve cusp repair was performed in 6 cases, such as plication of the free margin( 4 cases), decalcification(1 case) and raphe release(1 case).Results:None of the patients died in hospital or underwent rethoracotomy for hemostasis. During the operation, the duration of CPB time was(171.0±25.6) minutes and the duration of cross-clamp time was(134.0±23.2) minutes. There were 12 cases of aortic valve regurgitation and 8 cases of mild regurgitation. The mean follow-up was(15.1±9.8) months(4-33 months). During the follow-up period, there were 2 cases with moderate aortic regurgitation no need reoperation, while the rest of the patients had no or mild regurgitation. There are no patients undergoing reoperation. During the follow-up, 1 patient suffered coronary artery embolism in left circumflex artery and recovered after medicine treatment.Conclusion:Reimplantation with aortic valve sparing root replacement is safe and effective in the treatment of aortic root aneurysm, and the early and mid-term follow-up results are satisfactory, which can avoid anticoagulation-related complications and is suitable for young patients.
