Acute aortic dissection (AAD) is a serious disease characterized by high mortality. However, there are no accurate indicators to predict in-hospital mortality. The objective of this study was to identify the potential value of ischemia modified albumin (IMA) in prediction of in-hospital mortality of AAD patients. This was a single-center, prospective study involved 314 patients undergoing AAD, including 197 males and 117 females, aged 26–87 (57.14 ± 21.71) years old, 116 cases of TAAD and 198 cases of TBAD (37 cases of complicated, 114 cases of high risk, and 47 cases of uncomplicated), 228 cases were underwent surgery/intervention treatment (77 cases of TAAD,151 cases of TBAD) and 86 cases were underwent conservative therapy (39 cases of TAAD, 47 cases of TBAD). The basic data, on-admission IMA level, and the all-cause in-hospital mortality was recorded. IMA in the non-survivor group and TAAD group was found to be significantly higher than that in the survivor group and TBAD group (P < 0.001). Multivariate logistic regression analysis results revealed that age (OR = 1.923, 95%CI: 1.102–4.481, P = 0.020), conservative therapy (OR = 17.892, 95%CI: 7.641–24.748, P < 0.001), D-dimer level (OR = 3.517, 95%CI: 1.874–7.667, P = 0.011) and IMA level (OR = 5.406, 95%CI: 2.951–10.395, P = 0.004) served as independent risk factors for in-hospital mortality of TAAD patients. And D-dimer level (OR = 2.241, 95%CI: 1.475–5.663, P = 0.018), IMA level (OR = 3.115, 95%CI: 1.792–6.925, P = 0.009) also served as independent risk factors for in-hospital mortality of TBAD patients, whereas surgery (OR = 0.110, 95%CI: 0.075–0.269, P < 0.001) was the protective factor of in-hospital mortality of TAAD patients. After IMA prediction, the AUC, optimal cut-off value, sensitivity, and the specificity of in-hospital mortality of AAD patients were observed to be 0.801 (95%CI: 0.744–0.858), 86.55 U/mL, 79.1%, and 73.2%, respectively. In addition, it was found that AUC was 0.799 (95%CI: 0.719–0.880) in TAAD and 0.753 (95% CI: 0.641–0.866) in TBAD. Overall, it was concluded that on-admission IMA level acted as an independent prediction index for in-hospital mortality of AAD patients.
Objective: To investigate the safety and efficacy of two-stage type II hybrid aortic arch repair (HAR) in elderly patients with acute type A aortic dissection (a-TAAD). Methods: This was a single-center, prospective study involved 119 patients with a-TAAD, included 82 males and 37 females, aged 22 ~81 years old. Eighty-eight patients underwent total aortic arch replacement (TAR) with stented frozen elephant trunk (FET) implantation (TAR with FET group) and 31 patients underwent two-stage type II HAR (HAR group). Propensity score matching (PSM) was applied to adjust for preoperative data, and 25 pairs were matched successfully. The preoperative, perioperative, postoperative and follow-up data in the HAR group and TAR with FET group were compared. Results: Fifteen patients died during the perioperative period; 13 cases were in the TAR with FET group and 2 cases were in the TAR group. The age, body mass index, cerebral infarction, renal insufficiency were significantly higher, and the 24-h fluid drainage, the incidence of acute liver injury, acute kidney injury and pulmonary infectionwere were lower in the HAR group. Moreover, the mechanical ventilation time, intensive care unit time, hospital stay timewere shorter in the HAR group.The follow-up period ranged from 12 to 54 months, with 7 deaths (9.3%) in the TAR with FET group and 2 deaths (6.9%) in the HAR group. The true lumen of the aortic arch (P<0.001) and the middle descending thoracic aorta were larger and the false lumen thrombosis rates of the middle descending thoracic aorta and renal artery level were higher in the HAR group. Conclusion: Two-stage type II HAR is a safe and effective method for elderly patients with a-TAAD. It may be a good choice for elderly patients with a-TAAD and comorbidities.
