目的 探讨术前血清肌酐（sCr）、估测肾小球滤过率（eGFR）对急性A型夹层术后急性肾损伤3级（AKI 3级）及连续性肾脏替代治疗（CRRT）的影响。方法 回顾性分析广州市第一人民医院2017年1月—2022年12月6年间收治的143例行Bentall或升主动脉置换+Sun’s手术的急性Stanford A型夹层患者术前sCr及eGFR、术后24 h及48 h sCr、尿量、术后AKI及CRRT情况。应用ROC曲线（受试者特征曲线）分析术前sCr、eGFR对术后AKI 3级及CRRT的影响。结果 术后AKI 3级27例（18.9%）,CRRT 14例（9.8%）。发生AKI 3级及CRRT的患者术前sCr水平升高（AKI3级与AKI0-2级组间比较t’=-2.722,P=0.011,CRRT与非CRRT组间比较t’=-2.184,P=0.048）、eGFR降低（AKI3级与AKI0-2级组间比较t=4.585,P<0.001,CRRT与非CRRT组间比较t=4.932,P<0.001）。ROC曲线分析提示术前sCr可有效预测术后AKI 3级（AUC 0.768,临界点123 μmol/L,灵敏度67%,特异度85%）及CRRT（AUC 0.848,临界点137.5 μmol/L,灵敏度71%,特异度88%）。eGFR可预测AKI 3级[AUC 0.761,临界点56.25 mL/（min·1.73 m²）,灵敏度67%,特异度83%]及CRRT[AUC 0.855,临界点47.6 mL/（min·1.73 m²）,灵敏度71%,特异度87%]。手术合并低心排血量等肾灌注不良时,eGFR低于75.9 mL/（min·1.73 m²）,术后CRRT发生率增加。结论 急性A型夹层术前sCr及eGFR影响术后AKI 3级及CRRT的发生。sCr>123 μmol/L、eGFR低于58.25 mL/（min·1.73 m²）的患者术后AKI 3级发生率增加。sCr>137.5 μmol/L、eGFR低于47.6 mL/（min·1.73 m²）,或合并肾灌注不良的患者术后CRRT发生率增加。

Objective To explore the influences of preoperative serum creatinine（sCr）and estimated glomerular filtration rate（eGFR）on postoperative stage 3 acute kidney injury（AKI）or continuous renal replacement treatment（CRRT）in patients with acute Stanford type A aortic dissection（ATAAD）．Methods From July 2017 to December 2022,143 ATAAD patients who underwent Bentall or ascending aortic replacement and total arch replacement and stented elephant trunk were retrospective analyzed．Data included preoperative sCr and eGFR,postoperative sCr,eGFR,urine volume,AKI and CRRT at 24 h and 48 h．Receiver operating characteristic（ROC）curve were used to analyze the influences of preoperative sCr and eGFR on stage 3 AKI and CRRT．Results Stage 3 AKI occurred in 27（18.9%）patients,including 14 patients who required CRRT．sCr was significantly higher in stage 3 AKI or CRRT group（AKI 3 vs AKI 0-2 group：t’=-2.722,P=0.011,CRRT vs non-CRRT group：t’=-2.184,P=0.048）,and eGFR was significantly lower（AKI 3 vs AKI 0-2 group：t=4.585,P<0.001,CRRT vs non-CRRT group：t=4.932,P<0.001）．Preoperative sCr could effectively predict postoperative stage 3 AKI（AUC 0.768,the best cut-off value was 123 μmol/L,sensitivity 67%,specificity 85%）and CRRT（AUC 0.848,the best cut-off value was 137.5 μmol/L,sensitivity 71%,specificity 88%）．Preoperative eGFR could predict postoperative stage 3 AKI（AUC 0.761,the best cut-off value was 56.25mL/（min·1.73 m²）,sensitivity 67%,specificity 83%）and CRRT（AUC 0.855,the best cut-off value was 47.6 mL/（min·1.73 m²）,sensitivity 71%,specificity 87%）．CRRT requirement significantly increased in patients with eGFR lower than 75.9 mL/（min·1.73 m²） who complicated with peripheral malperfusion．Conclusion sPreoperative sCr and eGFR have significant influences on incidence of postoperative stage 3 AKI and CRRT．Postoperative stage 3 AKI significantly increase in patients with sCr more than 123 μmol/L or eGFR lower than 56.25mL/（min·1.73 m²）．Postoperative CRRT significantly increase in patients with sCr more than 137.5 μmol/L,eGFR lower than 47.6mL/（min·1.73 m²）,or peripheral malperfusion．

目的 探究和分析本组腹主动脉瘤腔内治疗病例并发症发生的原因及预防、处理策略。方法 对本团队在2014年1月—2017年12月实施的37例腹主动脉瘤腔内修复手术病例进行回顾性分析。结果 共有11例发生并发症,其中3例为术中I型内漏、1例术后支架移位致Ⅰ型内漏、1例术后Ⅲ型内漏、1例术中Ⅳ型内漏,全部经处理后内漏消失;术后髂动脉支架内血栓1例,经取栓后血流恢复;术后股动脉狭窄闭塞1例,经取栓并行股动脉人工血管置换后血流恢复;术后移植物反应1例,对症处理后症状消失出院;2例双侧髂内动脉栓塞致术后盆腔疼痛,随访疼痛消失,无跛行。结论 腹主动脉瘤腔内修复治疗本身存在内漏、血栓、血管入路损伤、移植物反应等相关并发症。术前正确评估并严格掌握适应症以及具有成熟的操作经验,是减少并发症发生的关键。

Objective To discuss and analyze the occurrence causes, prevention and treatment methods of complications in the endovascular repair of patients with abdominal aortic aneurysm. Methods Totally 37 cases of patients with abdominal aortic aneurysm underwent endovascular repair in our hospital from January 2014 to December 2017 were retrospectively analyzed. Results The complications were occurred in 11 cases, which including intra-operative typeⅠendoleak in 3 cases, postoperative typeⅠendoleak caused by stent displacement in 1 case; intra-operative type Ⅲ endoleak in 1 case; postoperative type Ⅳ endoleak in 1 case. all of the endoleak events disappeared after dealing. There was postoperative iliac artery stent thrombosis in 1 case, the blood flow was restored after thrombectomy; postoperative femoral artery stenosis or occlusion in 1 case, the blood flow was restored after thrombectomy and femoral artery artificial vascular replacement; postoperative host versus graft reaction in 1 case, no stent infection was found; and postoperative bilateral pelvic pain caused by internal iliac artery embolization in 2 cases, the pain disappeared during the follow-up visit, and the patients were free from lameness. Conclusion The complications related to endoleak, thrombosis, vascular approach injury and host versus graft reaction are existing with the endovascular repair itself of abdominal aortic aneurysm. The correct preoperative evaluation as well as strict control of indications and mature operational experience are the key to reduce the occurrence of complications.
