Objective: To explore the prognostic value of simple renal cyst (SRC) for adverse events in patients receiving thoracic endovascular aortic repair (TEVAR) for Stanford B aortic dissection (TBAD). Methods: This study is a retrospective cohort study. Consecutive patients receiving TEVAR for TBAD between January 2010 and December 2015 were enrolled in this study. The patients were divided into SRC group and non-SRC group. With sex and age ±2 years old as matching factors, SRC group and non-SRC group were matched by 1∶1. Collect and compare the differences of clinical data between the two groups. Adverse events were recorded through outpatient, telephone follow-up and in-hospital review. After adjusting for confounding factors, multivariate Cox regression was used to analyze the risk factors of aortic adverse events. Kaplan-Meier method was used to analyze the survival curve of SRC group and non-SRC group. Results: A total of 692 consecutive patients were recruited. Patients were divided into SRC group (n=235) and non-SRC group (n=457). After 1∶1 matching, there were 229 cases in SRC group and no SRC group respectively. The age of SRC group was (62.3±10.4) years old, 209 cases were male (91.3%), and the age of no SRC group was (62.0±10.2) years old, 209 cases were male (91.3%). Cox regression analysis showed that, after adjusting for confounding factors, comorbid SRC (HR=1.991, 95%CI: 1.090-3.673, P=0.025), TEVAR in the acute phase (HR=13.635, 95%CI: 5.969-31.147, P=0.001), general anesthesia (HR=2.012, 95%CI: 1.066-3.799, P=0.031) are independent factors of aortic-adverse events after TEVAR for TBAD. Kaplan-Meier analysis showed that the cumulative survival rate of SRC group was significantly lower than non-SRC group (log-rank P=0.031, 0.005). Conclusion: SRC is an independent predictor of aortic-related adverse events in patients following TEVAR for TBAD.

Objective: To explore the clinical characteristics and prognostic factors of female patients with Stanford type B aortic dissection. Methods: This is a single-centre retrospective study. Consecutive patients diagnosed with Stanford type B aortic dissection in General Hospital of Northern Theater Command from June 2002 to August 2021 were enrolled, and grouped based on sex. According to the general clinical conditions and complications of aortic dissection tear, patients were treated with thoracic endovascular aortic repair, surgery, or optimal medication. The clinical characteristics and aortic imaging data of the patients at different stages were collected, adverse events including all-cause deaths, stroke, and occurrence of aortic-related adverse events were obtained during hospitalization and within 30 days and at 1 and 5 years after discharge. According to the time of death, death was classified as in-hospital death, out-of-hospital death, and in-hospital death was divided into preoperative death, intraoperative death and postoperative death. According to the cause of death, death was classified as aortic death, cardiac death and other causes of death. Aortic-related adverse events within 30 days after discharge included new paraplegia, post-luminal repair syndrome, and aortic death; long-term (≥1 year after discharge) aortic-related adverse events included aortic death, recurrent aortic dissection, endoleak and distal ulcer events. The clinical characteristics, short-term and long-term prognosis was compared between the groups. Logistic regression analysis was used to explore the association between different clinical factors and all-cause mortality within 30 days in female and male groups separately. Results: A total of 1 094 patients with Stanford type B aortic dissection were enrolled, mean age was (53.9±12.1) years, and 861 (78.7%) were male and 233 (21.3%) were female. (1) Clinical characteristics: compared with male patients, female patients were featured with older average age, higher proportion of aged≥60 years old, back pain, anemia, optimal medication treatment, and higher cholesterol level; while lower proportion of smoking and drinking history, body mass index, calcium antagonists use, creatine kinase level, and white blood cell count (all P<0.05). However, there was no significant difference in dissection tear and clinical stage, history of coronary heart disease, diabetes, hypertension, and cerebrovascular disease between female and male patients (all P>0.05). (2) Follow-up result: compared with male patients, female patients had a higher rate of 30-day death [6.9% (16/233) vs. 3.8% (33/861), P=0.047], in-hospital death (5.6% (13/233) vs. 2.7% (23/861), P=0.027), preoperative death (3.9% (9/233) vs. 1.5% (12/861), P=0.023) and aorta death (6.0% (14/233) vs. 3.1% (27/861), P=0.041). The 1-year and 5-year follow-up results demonstrated that there were no significant differences in death, cerebrovascular disease, and aorta-related adverse events between the two groups (all P>0.05). (3) Prognostic factors: the results of the univariate logistic regression analysis showed that body mass index>24 kg/m2 (HR=1.087, 95%CI 1.029-1.149, P=0.013), history of anemia (HR=2.987, 95%CI 1.054-8.468, P=0.032), hypertension (HR=1.094, 95%CI 1.047-1.143, P=0.040) and troponin-T>0.05 μg/L (HR=5.818, 95%CI 1.611-21.018, P=0.003)were associated with an increased risk of all-cause mortality within 30 days in female patients. Conclusions: Female patients with Stanford type B aortic dissection have specific clinical characteristics, such as older age at presentation, higher rates of anemia and combined back pain, and higher total cholesterol levels. The risk of death within 1 month is higher in female patients than in male patients, which may be associated with body mass index, hypertension, anemia and troponin-T, but the long-term prognosis for both female and male patients is comparable.
