Conventional Treatment Group

Background: The hypothermic circulatory arrest (HCA) is an indispensable step in the surgical treatment of an acute type A aortic dissection (ATAAD), which could greatly affect the postoperative outcome. We modified the HCA technique and validated the feasibility and superiority of the new approach relative to the conventional method. Methods and results: Eighty-eight patients with ATAAD were enrolled in this study between May 2016 and April 2018. Of those, 36 patients in the Conventional treatment group had circulatory arrest at 25°C for about 16-28 minutes, while 52 patients in the Modification group underwent a circulatory arrest at 28°C for only 1-3 minutes. The preoperative clinical data and postoperative clinical outcomes were compared between the two groups. No intraoperative mortality occurred in any of the cases. No significant differences were observed in the aortic cross-clamp times during the cardiopulmonary bypass (CPB) between the two groups. In the Modification group, several indicators, such as mechanical ventilation time, postoperative 48-h drainage volume, blood transfusion volume, the ICU-stay time and postoperative hospital stay, were reduced significantly as compared with those in the Conventional group. Whereas three postoperative deaths in the hospital occurred in the Conventional treatment group, all the patients in the Modification group were cured. There is no difference in the incidence of postoperative complications between the two groups. The patients had a 100% follow up with a mean of 17 ± 6 months. Conclusions: A moderate hypothermia with a short circulatory arrest is a safe and effective HCA approach that provides satisfactory early and near-midterm results in the patients who received ATAAD treatment.

Before And After

Background: The objective of this study was to compare the incidence of severe systemic inflammatory response syndrome (sSIRS) after total aortic arch replacement between patients who underwent moderate hypothermic circulatory arrest (MHCA) and those who underwent deep hypothermic circulatory arrest (DHCA).Methods: At Fuwai Hospital, 600 patients who underwent total aortic arch replacement with MHCA or DHCA from January 2013 to December 2016 were consecutively enrolled and divided into DHCA (14.1–20.0°C) and MHCA (20.1–28.0°C) groups. Preliminary statistical analysis revealed that some baseline indicators differed between the two groups; therefore, propensity score matching (PSM) was used to balance the covariates. Post-operative sSIRS as the primary outcome was compared between the groups both before and after PSM.Results: A total of 275 (45.8%) patients underwent MHCA, and 325 (54.2%) patients underwent DHCA. After PSM analysis, a total of 191 matched pairs were obtained. The overall incidence of sSIRS was 27.3%. There was no significant difference in post-operative sSIRS between the MHCA group and the DHCA group in either the overall cohort or the PSM cohort (no-PSM: P = 0.188; PSM: P = 0.416); however, post-operative sSIRS was increased by ~4% in the DHCA group compared with the MHCA group in both the no-PSM and PSM cohorts (no-PSM: 29.5 vs. 24.7%; PSM: 29.3 vs. 25.1%). Both before and after PSM, the rates of gastrointestinal hemorrhage and pulmonary infection and post-operative length of stay were significantly increased in the DHCA group compared with the MHCA group (P < 0.05), and the remaining secondary outcomes were not significantly different between the groups.Conclusions: MHCA and DHCA are associated with comparable incidences of sSIRS in patients following total aortic arch replacement for type A aortic dissection. However, the MHCA group had a shorter cardiopulmonary bypass time, a shorter post-operative length of stay and lower pulmonary infection and gastrointestinal hemorrhage rates than the DHCA group. We cautiously recommend the use of MHCA for most total arch replacements in patients with type A aortic dissection.

Objective No evidence exists that profound hypothermic circulatory arrest (PHCA) improves survival or reduces the likelihood of distal aortic reoperation in patients with acute type A aortic dissection. Methods Records of 307 patients with acute type A aortic dissection from 1967 to 1999 were retrospectively reviewed. The influence of repair using PHCA (n=121) versus without PHCA (n=186) on death and freedom from distal aortic reoperation was analyzed using multivariable Cox regression models. Propensity score analysis identified a subset of 152 comparable patients in 3 quintiles (QIII–V) in which the effects of PHCA (n=113) versus no PHCA (n=39) were further compared. Results For all patients, 30-day, 1-year, and 5-year survival estimates were 81±2%, 74±3%, and 63±3% (±1 SE). Survival rates and actual freedom from distal aortic reoperation was not significantly different between treatment methods in the entire patient cohort nor in the matched patients in quintiles III–V. Treatment method was not associated with differences in early major complications, late survival, or distal aortic reoperation rates in the entire patient sample or in quintiles III–V. Conclusions Aortic repair with or without circulatory arrest was associated with comparable early complications, survival, and distal aortic reoperation rates in patients with acute type A aortic dissection. Despite the lack of concrete evidence favoring the use of PHCA, it does no harm, and most of our group uses PHCA regularly because of its practical technical advantages and theoretical potential merit.
