Abstract OBJECTIVES Postoperative acute kidney injury (AKI) is known as a risk factor for death after surgery for Stanford type A acute aortic dissection under hypothermic circulatory arrest. It may also adversely affect long-term survival. We searched for modifiable risk factors for postoperative AKI, focusing on lower body ischaemic time. METHODS We reviewed 191 patients undergoing surgical repair for Stanford type A acute aortic dissection. The distal anastomosis depended on excluding the primary tear location, resulting in ascending/hemiarch (n = 119), partial arch (n = 18) and total arch replacement (n = 54). We defined an increase in the serum creatinine level to ≧2 times the baseline level as AKI. The incidence of AKI was investigated with multivariate analysis of its risk factors. RESULTS Postoperative AKI was observed in 49 patients (26%), 31% of whom required renal replacement therapy. The overall hospital mortality rate was 8.5%. Postoperative AKI, preoperative shock and organ malperfusion were predictors of hospital death. Multivariate stepwise logistic regression analysis identified age, body mass index, preoperative chronic kidney disease and lower body ischaemic time as risk factors for postoperative AKI. CONCLUSIONS Although surgical repair for Stanford type A acute aortic dissection showed favourable results, the incidence of postoperative AKI is still high, closely associated with hospital death. Lower body ischaemic time should be recognized specifically as a modifiable surgical risk factor for postoperative AKI.

Hemiarch Replacement

Background Aortic enlargement after hemiarch replacement (HAR) for acute type A aortic dissection (AAAD) is a serious problem. We reviewed our experience and analyzed the risk factors for aortic enlargement. Methods During April 2005 to December 2017, 364 patients underwent HAR for AAAD. Seventy-three patients fulfilled the inclusion criteria. We analyzed the change in aortic diameter, aortic growth rate, and major adverse aortic events (MAAEs) and their association with luminal communication of the aortic arch. Results Anastomotic communication, supra-aortic communication (SAC), and distal aortic communication were found in 34 (46.6%), 28 (38.4%), and 20 (27.4%) patients, respectively. The aortic growth rate was high because of the presence of SAC, distal aortic communication, and the number of coexisting aortic communication. Univariate analysis showed that the presence of SAC and an initial aortic diameter > 35 mm at 20 mm distal to the left subclavian artery and at the pulmonary artery bifurcation (PAB) were risk factors for MAAEs. Multivariate analysis showed that SAC and an initial aortic diameter > 35 mm at the PAB were independent risk factors for MAAEs. Conclusion SAC, distal aortic communication, and the number of coexisting aortic communication are significant risk factors for aortic enlargement after HAR for AAAD. SAC and an initial aortic diameter > 35 mm at the PAB are independent risk factors for MAAEs after this procedure.

Abstract Objective This study aims to evaluate the diagnostic value of D-dimer for acute aortic dissection (AAD) by the method of meta-analysis. Methods PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), and Wanfang databases from the establishment of the databases to December 2020 were systematically searched, and the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) system was used to evaluate the quality of the literature. STATA 15.0 software was applied to calculate the pooled sensitivity, specificity, diagnostic odds ratio (DOR), positive likelihood ratio (+LR), negative likelihood ratio (−LR) to draw summary receiver operating characteristics (SROC) curve and calculate the area under the curve (AUC). Meta-regression and subgroup analyses were used to explore the source of heterogeneity. Results A total of 16 clinical studies were enrolled in this study, including 1135 patients. The results of the meta-analysis showed that the pooled sensitivity was 0.96 (95% CI 0.91–0.98), the pooled specificity was 0.70 (95% CI 0.57–0.81), and the pooled DOR was 56.57 (95% CI 25.11–127.44), the pooled +LR was 3.25 (95% CI 2.18–4.85), the pooled −LR was 0.06 (95% CI 0.03–0.12), and the AUC was 0.94 (95% CI 0.91–0.95). Meta-regression and subgroup analysis results showed that publication year, sample size and cutoff value might be sources of heterogeneity. When the concentration of D-dimer was less than or equal to 500 ng/ml, the sensitivity significantly increased. Conclusion D-dimer has an excellent diagnostic value for AAD. It is a useful tool for detecting suspected AAD because of the excellent pooled sensitivity. D-dimer ≤ 500 ng/ml increases the potential to identify the suspected patients with AAD.

Abstract. Background: We investigated the prevalence of recurrent pain and its relationship with in-hospital mortality in acute aortic dissection (AAD). Patients and methods: Between 2011 and 2016, 234 AAD patients were selected. Recurrent pain was defined as a mean of VAS > 3, within 48 hours following hospital admission or before emergency operation. Patients with and without recurrent pain were divided into group I and group II, respectively into type A AAD and type B AAD patients. Our primary outcome was in-hospital mortality. Results: The incidence of recurrent pain was 24.4 % in AAD patients. Incidence of recurrent pain was higher in type A AAD patients than type B AAD patients (48.9 vs. 9.6 %). Overall in-hospital mortality was 25.6 %. Type A AAD had a higher in-hospital mortality than type B AAD patients (47.7 vs. 12.3 %). Group I had significantly higher in-hospital mortality than group II (type A: 79.1 vs. 17.8 %; type B: 57.1 vs. 7.6 %, all P < 0.001), as was the case with medical managed patients (type A: 72.1 vs. 13.3 %; type B: 35.7 vs. 2.3 %, all P < 0.001). Logistic regression analysis showed that use of one drug alone and waist pain were predictive factors for recurrent pain in type A AAD and type A AAD patients, respectively (OR 3.686, 95 % CI: 1.103~12.316, P = 0.034 and OR 14.010, 95 % CI: 2.481~79.103, P = 0.003). Recurrent pains were the risk factors (type A: OR 11.096, 95 % CI: 3.057~40.280, P < 0.001; type B: OR 14.412, 95 % CI: 3.662~56.723, P < 0.001), while invasive interventions were protective (type A: OR 0.133, 95 % CI: 0.035~0.507, P < 0.001; type B: OR 0.334, 95 % CI: 0.120~0.929, P = 0.036) for in-hospital mortality in AAD patients. Conclusions: Approximately one-fourth of AAD patients presented with recurrent pains, which might increase in-hospital mortality. Thus, interventional strategies at early stages are important.
