Abstract Background Hepatic dysfunction (HD) increases the morbidity and mortality rates after cardiac surgery. However, few studies have investigated the association between HD and acute DeBakey type I aortic dissection (ADIAD) surgery. This retrospective study aimed to identify risk factors for developing HD in patients who received acute type I aortic dissection repair and its consequences. Methods A total of 830 consecutive patients who received ADIAD surgery from January 2014 to December 2019 at our center were screened for this study. The End-Stage Liver Disease (MELD) score more than 14 was applied to identify postoperative HD. Logistic regression model was applied to identify risk factors for postoperative HD, Kaplan–Meier survival analysis and Cox proportional hazards regression assay were conducted to analyze the association between HD and postoperative long-term survival. Results Among 634 patients who eventually enrolled in this study, 401 (63.2%) experienced postoperative HD with a 30-Day mortality of 15.5%. Preoperative plasma fibrinogen level (PFL) [odds ratio (OR): 0.581, 95% confidence interval (CI): 0.362–0.933, P = 0.025], serum creatinine (sCr) on admission (OR: 1.050, 95% CI 1.022–1.079, P < 0.001), cardiopulmonary bypass (CPB) time (OR: 1.017, 95% CI 1.010–1.033, P = 0.039), and postoperative mechanical ventilation (MV) duration (OR: 1.019, 95% CI 1.003–1.035, P = 0.020) were identified as independent risk factors for developing postoperative HD by multivariate analyses. In addition, the Kaplan–Meier analysis indicated that the long-term survival rate was significantly different between patients with or without postoperative HD. However, the hazard ratios of long-term survival for these two groups were not significantly different. Conclusions HD was a common complication after ADIAD surgery and associated with an increasing 30-Day mortality rate. Decreased PFL, elevated sCr, prolonged CPB duration, and longer postoperative MV time were independent risk factors for postoperative HD.

Objectives: The aim of this study was to evaluate independent risk factors predictive for mortality of patients with Stanford A acute aortic dissection. Methods: From January 2006 to March 2015, a total of 240 consecutive patients diagnosed with acute Stanford A acute aortic dissection underwent surgical aortic repair in our center. After analysis of pre- and perioperative variables, univariate logistic and multivariate logistic regression analyses were performed for mortality of patients. Subsequently, Kaplan–Meier estimation analysis of short- and long-term survival of these variables was carried out. Results: Primary entry tear in descending aorta (odds ratio = 4.71, p = 0.021), preoperative international normalized ratio higher than 1.2 (odds ratio = 7.36, p = 0.001), additional coronary artery bypass grafting (odds ratio = 3.39, p = 0.003), cannulation in ascending aorta (odds ratio = 3.22, p = 0.005), preoperative neurological coma (odds ratio = 3.30, p = 0.003), and reduced perfusion (odds ratio = 2.91, p = 0.006) as well as prolonged reperfusion time (odds ratio = 3.36, p = 0.002) showed to be independent predictors for early mortality as well as for late mortality (hazard ratio of all variables p < 0.05). Kaplan–Meier survival estimation analysis with up to 9-year-follow-up in terms of these risk factors showed significantly poorer short- and long-term survival (log-rank and Breslow test all p < 0.05). Conclusion: Our study revealed that early and late mortality of patients with Stanford A acute aortic dissection surgery was significantly influenced by preoperative and perioperative variables as independent predictors especially of variables displaying coronary, cerebral, and visceral malperfusion. Also, short- and long-term survival of patients was significantly poorer in terms of these risk factors.

Abstract Objective: The purpose of this study was to identify the relationship between coagulopathy during the perioperative period (before the operation and on the first day after the operation) and the long-term survival of TBI patients undergoing surgery, as well as to explore the predisposing risk factors that may cause perioperative coagulopathy.Methods: This retrospective study included 447 TBI patients who underwent surgery from January 1, 2015 to April 25, 2019. Clinical parameters, including patient demographic characteristics, biochemical tests, perioperative coagulation function tests (before the operation and on the first day after the operation) and intraoperative factors were collected. Log-rank univariate analysis and Cox regression models were conducted to assess the relationship between perioperative coagulopathy and the long-term survival of TBI patients. Furthermore, univariate and multivariate analyses were performed to identify the underlying risk factors for perioperative coagulopathy.Results: Multivariate Cox regression analysis identified age, AIS(head) = 5, GCS ≤ 8, systolic pressure at admission < 90 mmHg and postoperative coagulopathy (all P < 0.05) as independent risk factors for survival following TBI; we were the first to identify postoperative coagulopathy as an independent risk factor. According to multivariate logistic regression analysis, for the first time, abnormal ALT and RBC at admission, preoperative coagulopathy, infusion of colloidal solution > 1100 mL and intraoperative bleeding > 950 mL (all P < 0.005) were identified as independent risk factors for postoperative coagulation following surgery after TBI.Conclusions: Those who suffered from postoperative coagulopathy due to TBI had a higher hazard for poor prognosis than those who did not. Closer attention should be paid to postoperative coagulopathy and more emphasis should be placed on managing the underlying risk factors.

Background: Young patients (pts) with acute aortic dissection (AAD) have distinct risk factors and presenting symptoms compared to older pts, but whether these differences extend past discharge is relatively unknown. Methods: Among pts presenting with AAD enrolled in the International Registry of Acute Aortic Dissection, pts <40 (N=280) were compared with pts ≥ 40 (N=3585). Chi-square analysis or Fischer’s Exact test were performed for categorical variables; age was compared using Student’s T-test. Kaplan-Meier curves were generated for freedom from adverse events rates 0-60 months following discharge. Mean follow-up was 28.6 months. Results: Significant differences in demographics and history were noted between pts <40 and the older cohort. Young pts more commonly had type A AAD (71.8%, 201/280, v. 64.6%, 2317/ 3585, p<0.016), while type B AAD was more typical in older pts (p<0.016). On imaging studies, pts <40 were less likely to present with IMH (7.3%, 246/3355, v. 2.3%, 6/266, p=0.002), but were more likely to have a patent false lumen (77.9%, 141/181, v. 62.1%, 1425/2295, p<0.001). Surgical management was more common in young pts, for both AAD types. In-hospital complications or mortality did not differ between groups. Kaplan-Meier analysis demonstrated better long-term survival in young pts compared to those ≥ 40 (p=0.029). Kaplan-Meier analyses of freedom from adverse events at 5 years illustrated no difference in aortic growth between groups, but significantly more late interventions in younger pts (p=0.006). Conclusions: Young pts show distinct differences in comparison to older pts, specifically regarding presentation, AAD type and management. Long-term survival and follow-up intervention rates are higher in young pts.

Abstract OBJECTIVES We evaluated the operative and long-term outcomes of the frozen elephant trunk (FET) technique for acute type A aortic dissection. METHODS This study evaluated 426 consecutive patients who underwent aortic repair for acute type A aortic dissection from June 2007 to December 2018 at our centre. Of these, 139 patients underwent total arch replacement with FET (FET group), and 287 underwent other procedures (no FET group). Ninety-two patients in the FET group were matched to 92 patients in the no FET group by using propensity score matching analysis. RESULTS Thirty-day mortality and neurological dysfunction were not significantly different between the FET and no FET groups (1.4% vs 2.4%, P = 0.50 and 5.0% vs 6.3%, P = 0.61, respectively). Long-term survival was better in the FET group than in the no FET group (P = 0.008). Freedom from distal thoracic reintervention was similar in the FET and no FET groups (P = 0.74). In the propensity-matched patients, freedom from aortic-related death was better in the FET group than in the no FET group (P = 0.044). CONCLUSIONS Operative outcomes showed no significant difference between the 2 groups. FET contributes to better long-term survival in patients with acute type A aortic dissection.

Abstract Background Surgical resection remains the best option for long-term survival in colorectal cancer (CRC); however, surgery can lead to tumor cell release into the circulation. Previous studies have also shown that surgery can affect cancer cell growth. The role of perioperative factors influencing long-term survival in patients presenting for CRC surgery remains to be investigated. Methods This retrospective single–center cohort study was conducted to collect the clinical data of patients who underwent elective laparoscopic resection for CRC from January 2014 to December 2015, namely clinical manifestations, pathological results, and perioperative characteristics. Survival was estimated using the Kaplan–Meier log-rank test. Univariable and multivariable Cox regression models were used to compare hazard ratios (HR) for death. Results A total of 234 patients were eligible for analysis. In the multivariable Cox model, tumor-node-metastasis (TNM) stage (stage IV: HR 30.63, 95% confidence interval (CI): 3.85–243.65; P = 0.001), lymphovascular invasion (yes: HR 2.07, 95% CI 1.09–3.92; P = 0.027), inhalational anesthesia with isoflurane (HR 1.96, 95% CI 1.19–3.21; P = 0.008), and Klintrup–Makinen (KM) inflammatory cell infiltration grade (low-grade inflammation: HR 2.03, 95% CI 1.20–3.43; P = 0.008) were independent risk factors affecting 5-year overall survival after laparoscopic resection for CRC. Conclusions TNM stage, lymphovascular invasion, isoflurane, and KM grade were independent risk factors affecting CRC prognosis. Sevoflurane and high-grade inflammation may be associated with improved survival in CRC patients undergoing resection.
