Abstract
We built up a risk stratification model to divide acute type A aortic dissection (aTAAD) patients into low- and high-risk groups, further, to evaluate the risk factors for postoperative mortality. A total of 1364 patients from 2010 to 2020 in our center were retrospectively analyzed. More than twenty clinical variables were related with postoperative mortality. The postoperative mortality of the high-risk patients was doubled than the low-risk ones (21.8% vs 10.1%). The increased operation time, combined coronary artery bypass graft, cerebral complications, re-intubation, continuous renal replacement therapy and surgical infection were risk factors of postoperative mortality in low-risk patients. In addition, postoperative lower limbs or visceral malperfusion were risk factors, axillary artery cannulation and moderate hypothermia were protective factors in high-risk patients. A scoring system for quick decision-making is needed to select appropriate surgical strategy in aTAAD patients. For low-risk patients, different surgical treatments can be performed with similar clinical prognosis. Limited arch treatment and appropriate cannulation approach are crucial in high-risk aTAAD patients.

Sci Rep 2023; 13:1048. [PMID: 36658204 PMCID: PMC9852255 DOI: 10.1038/s41598-022-27099-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Accepted: 12/26/2022] [Indexed: 01/20/2023] Open
Abstract
Acute Stanford type A aortic dissection (ATAAD) with sudden onset and high mortality requiries a standard Bentall operation and a accurate prognosis in common, together with alteration of CO2 combining power (CO2CP) and serum sodium rase concern, hence, we evaluated the prognostic value of CO2CP combined with serum sodium in ATAAD patients. This retrospective study included 183 patients who underwent Bentall operation for ATAAD from 2015 to 2021 in the Fourth Hospital of Hebei Medical University, subsequently followed grouping by the levels of CO2CP and serum sodium. The study endpoint was 30-day all-cause mortality, and the prognostic value of CO2CP combined with serum sodium levels in ATAAD patients were evaluated with multivariate logistic regression method. The postoperative incidence of in-hospital death and adverse events in patients with ATAAD were 18% and 25.7%, respectively. Combination of CO2CP and serum sodium for predicting ATAAD death and adverse events presented a higher predictive value than each single indicator with ROC curve analysis (the AUC of CO2CP combined with serum sodium was 0.786, 95% CI 0.706-0.869, P < 0.001), along with CO2CP < 22.5 mmol/L + serum sodium > 138.5 mmol/L group had the worst prognostic. Multivariate regression analyse showed that CO2CP < 22.5 mmol/L combined with serum sodium > 138.5 mmol/L preferably predicted the prognosis of ATAAD (OR =6.073, 95% CI 2.557-14.425, P < 0.001). Consistently, the cumulative 30-day survival after surgery in ATAAD patients with the low CO2CP and high serum sodium simultaneously was the worst (log-rank P < 0.05). The combination of CO2CP and serum sodium increases the predictive value of prognosis, which is conducive to risk stratification of patients with ATAAD.

Int J Gen Med 2022; 15:3779-3788. [PMID: 35418773 PMCID: PMC8995175 DOI: 10.2147/ijgm.s357910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 03/23/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose Acute aortic syndrome is a constellation of life-threatening medical conditions for which rapid assessment and targeted intervention are important for the prognosis of patients who are at high risk of in-hospital death. The current study aims to develop and externally validate an early prediction mortality model that can be used to identify high-risk patients with acute aortic syndrome in the emergency department. Patients and Methods This retrospective multi-center observational study enrolled 1088 patients with acute aortic syndrome admitted to the emergency departments of two hospitals in China between January 2017 and March 2021 for model development. A total of 210 patients with acute aortic syndrome admitted to the emergency departments of Peking University Third Hospital between January 2007 and December 2021 was enrolled for model validation. Demographics and clinical factors were collected at the time of emergency department admission. The predictive variables were determined by referring to the results of previous studies and the baseline analysis of this study. The study’s endpoint was in-hospital death. To assess internal validity, we used a fivefold cross-validation method. Model performance was validated internally and externally by evaluating model discrimination using the area under the receiver-operating characteristic curve (AUC). A nomogram was developed based on the binary regression results. Results In the development cohort, 1088 patients with acute aortic syndromes were included, and 88 (8.1%) patients died during hospitalization. In the validation cohort, 210 patients were included, and 20 (9.5%) patients died during hospitalization. The final model included the following variables: digestive system symptoms (OR=2.25; P=0.024), any pulse deficit (OR=7.78; P<0.001), creatinine (µmol/L)(OR=1.00; P=0.018), lesion extension to iliac vessels (OR=4.49; P<0.001), pericardial effusion (OR=2.67; P=0.008), and Stanford type A (OR=10.46; P<0.001). The model’s AUC was 0.838 (95% CI 0.784–0.892) in the development cohort and 0.821 (95% CI 0.750–0.891) in the validation cohort, and the Hosmer–Lemeshow test showed p=0.597. The fivefold cross-validation demonstrated a mean accuracy of 0.94, a mean precision of 0.67, and a mean recall of 0.13. Conclusion This risk prediction tool uses simple variables to provide robust prediction of the risk of in-hospital death from acute aortic syndrome and validated well in an independent cohort. The tool can help emergency clinicians quickly identify high-risk acute aortic syndrome patients, although further studies are needed for verifying the prospective data and the results of our study.

The effects of DeBakey type acute aortic dissection and preoperative peripheral and cardiac malperfusion on the outcomes after surgical repair. POLISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2021; 18:1-7. [PMID: 34552637 PMCID: PMC8442082 DOI: 10.5114/kitp.2021.105187] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 01/16/2021] [Indexed: 12/23/2022]
Abstract
Introduction Emergent surgical repair of DeBakey type I and II acute aortic dissection represents the standard of care to prevent lethal complications. Aim Evaluation of the effect of extension of aortic dissection (AAD) according to DeBakey classification, type I and II AAD, and the relationship with preoperative peripheral and myocardial malperfusion on early outcome and the mid-term follow-up period. Material and methods A total of 135 patients who underwent AAD surgery between January 2015 and October 2019 were analysed. Results In total 103 patients were affected by DeBakey type I AAD and 32 by DeBakey type II; 56 patients preoperatively showed peripheral, cardiac malperfusion, or both. Intra-operative mortality was 11%. Postoperative peripheral, cardiac malperfusion, and intraoperative and postoperative mortality were lower for type II AAD. The protective factor for intra- and postoperative 60-day mortality was type II AAD (RR = 0.03, p = 0.001); independent predictors were hypertension, and preoperative cardiac and renal-visceral malperfusion. At 5 years the overall survival was 74 ±6.9%. Independent predictors of reduced survival were major extension of type I AAD (RR = 5.37, p < 0.05) and preoperative cardiac malperfusion (RR = 5.78, p < 0.05). Five-year freedom from cardiac death, redo surgical operation, and new vascular procedures on the thoracic and abdominal aorta was 92 ±5.7%, 99 ±1.2%, and 81 ±7.2%, respectively. Extension of DeBakey type I AAD into the thoracic-abdominal aorta segment was also a predictor of the need for new vascular procedures (RR = 1.66, p = 0.05). Conclusions A more favourable anatomy of DeBakey type II AAD is associated with better early and late outcomes after aortic repair. This is due to a lower incidence of peripheral and cardiac malperfusion.

Association between anion gap and mortality of aortic aneurysm in intensive care unit after open surgery. BMC Cardiovasc Disord 2021; 21:458. [PMID: 34556051 PMCID: PMC8459533 DOI: 10.1186/s12872-021-02263-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 09/03/2021] [Indexed: 01/16/2023] Open
Abstract
Background There has not been a well-accepted prognostic model to predict the mortality of aortic aneurysm patients in intensive care unit after open surgery repair. Otherwise, our previous study found that anion gap was a prognosis factor for aortic aneurysm patients. Therefore, we wanted to investigate the relationship between anion gap and mortality of aortic aneurysm patients in intensive care unit after open surgery repair. Methods From Medical Information Mart for Intensive Care III, data of aortic aneurysm patients in intensive care unit after open surgery were enrolled. The primary clinical outcome was defined as death in intensive care unit. Univariate analysis was conducted to compare the baseline data in different groups stratified by clinical outcome or by anion gap level. Restricted cubic spline was drawn to find out the association between anion gap level and mortality. Subgroup analysis was then conducted to show the association in different level and was presented as frost plot. Multivariate regression models were built based on anion gap and were adjusted by admission information, severity score, complication, operation and laboratory indicators. Receiver operating characteristic curves were drawn to compare the prognosis ability of anion gap and simplified acute physiology score II. Decision curve analysis was finally conducted to indicate the net benefit of the models. Results A total of 405 aortic aneurysm patients were enrolled in this study and the in-intensive-care-unit (in-ICU) mortality was 6.9%. Univariate analysis showed that elevated anion gap was associated with high mortality (P value < 0.001), and restricted cubic spline analysis showed the positive correlation between anion gap and mortality. Receiver operating characteristic curve showed that the mortality predictive ability of anion gap approached that of simplified acute physiology score II and even performed better in predicting in-hospital mortality (P value < 0.05). Moreover, models based on anion gap showed that 1 mEq/L increase of anion gap improved up to 42.3% (95% confidence interval 28.5–59.8%) risk of death. Conclusions The level of serum anion gap was an important prognosis factor for aortic aneurysm mortality in intensive care unit after open surgery.

Abstract
Objective Serum bicarbonate (HCO3-) level is strongly related to multiple cardiovascular complications. Currently, there is no study evaluating the prognostic ability of serum HCO3- level in intensive care unit (ICU) patients with acute aortic dissection (AAD). Hence, this study was to assess the relationship between admission serum HCO3- level and clinical outcomes in patients with AAD. Design Settings and Participants Clinical data were extracted from the MIMIC-III database. Cox proportional hazards models and Kaplan-Meier (KM) survival curve were used to evaluate the association between serum HCO3- levels and short- and long-term mortality in ICU patients with AAD. The subgroup analysis and the receiver operating characteristic (ROC) curve analysis and further KM survival curve based on best cut-off value were applied to assessment of the performance of HCO3- in predicting the mortality in each period (30 days, 90 days, 1 year and 5 years). Main Results Firstly, 336 eligible patients were trisected to low-HCO3- level group (<22 mmol/L), mid-HCO3- level group (22-24 mmol/L) and high-HCO3- level group (>24 mmol/L). Then, in multivariate analysis, the serum HCO3- of low levels (<22 mmol/L) was a significant risk predictor of all-cause mortality in 30 days, 90 days, 1 year and 5 years. Subgroup analyses indicated that there is no interaction in most strata. Finally, areas under ROC curve ranged from 0.60 to 0.69. Conclusion The low HCO3- serum level measured at ICU admission significantly predicts short-term and long-term mortality in AAD patients.

Abstract
Our aim was to analyze outcomes of patients aged 70 years or above presenting with type A acute aortic dissection (TAAAD) and cerebrovascular accident (CVA). A retrospective analysis of the International Registry of Acute Aortic Dissection (IRAD) was conducted. Patients aged 70 years or above (n = 1449) were stratified according to presence or absence of CVA before surgery (CVA: n = 110, 7.6%). In-hospital outcomes and mortality up to 5 years were analyzed. Additionally, in-hospital outcomes of patients who received medical management were described. No patient presenting with CVA over the age of 87 years underwent surgery. The rates of in-hospital mortality and post-operative CVA were significantly higher in patients presenting with CVA (in-hospital mortality: 32.7% vs 21.7%, P = 0.008; post-operative CVA: 23.4% vs 8.3%, P < 0.001). Presence of CVA was independently associated with significantly increased in-hospital mortality (odds ratio 2.99, 95% confidence interval 1.35 - 6.60, P = 0.007). In survivors of the hospital stay, presenting CVA had no independent influence on mortality up to 5 years (hazard ratio 1.52, 95% confidence interval 0.99 - 2.31, P = 0.54). In medically managed patients, exceedingly high rates of in-hospital mortality (71.4%) and CVA (90.9%) were noted. Patients presenting with TAAAD and CVA at ≥ 70 years of age are at significantly increased risk of in-hospital mortality, although long-term mortality is not affected in hospital survivors. Medical management is associated with poor outcomes. We believe that surgical management should be offered after critical assessment of comorbidities.

Abstract
Objective Surgical outcomes of acute type A aortic dissection have been recognized to be associated with the surgical volume of individual hospitals and surgeons. In this study, we aimed to investigate the results and learning curves of acute type A aortic dissection operations performed by early-career cardiovascular surgeons. Methods A total of 248 surgical repairs of acute type A aortic dissections were conducted at a tertiary medical center between 2010 and 2018. By using the cumulative sum test, cardiovascular surgeons in their early career were identified, and their performances were assessed. The outcomes of patients who were operated by early-career cardiovascular surgeons were compared with those by experienced or senior surgeons. Results During the study period, 202 (81.5%) of the 248 acute type A aortic dissection operations were performed primarily by the 4 newly appointed attending cardiovascular surgeons. In cumulative sum curves, all surgeons exhibited a steady performance throughout the study period. On the basis of our institutional result of acute type A aortic dissection operation, early career was defined as performing fewer than 32 acute type A aortic dissection operations. The 30-day mortality rates of acute type A aortic dissection operations performed by early-career surgeons were equivalent to those performed by experienced/senior surgeons (10.9% vs 12.5%, P = .844). There was also no difference in mid-term overall survival and aortic event-free survival between the 2 groups (P = .638 and P = .574, respectively). Conclusions In a center with a well-established program, cardiovascular surgeons could accomplish surgical repair of acute type A aortic dissection with adequate early- and mid-term results from the initiation of their careers.

Abstract
Acute type A aortic dissection (TAAD) with malperfusion syndrome remains a challenging diagnosis and optimal surgical management remains unsettled. We present a case and surgical approach employed for a patient with TAAD and malperfusion syndrome who presented with pulseless bilaterally extremities. Satisfactory outcomes can be achieved with early multidisciplinary collaboration and urgent repair of the aorta and simultaneous efforts to restore blood flow to ischemic tissue.
