Abstract
OBJECTIVES In adult aortic arch surgery, moderate hypothermic circulatory arrest (HCA) with selective antegrade cerebral perfusion (SACP) (MoHACP) is widely used, but the application of mild HCA with SACP (MiHACP) is still controversial. This meta-analysis aimed to compare clinical outcomes using MiHACP or MoHACP. METHODS Studies comparing outcomes of MiHACP or MoHACP in adult aortic arch surgery were searched from four databases from inception through April 2022. Primary outcomes were postoperative permanent neurological deficit (PND), temporary neurological deficit (TND), and mortality. Secondary outcomes included other common complications. Meta-analysis was conducted using a random-effects model in all cases. RESULTS Eleven comparative studies were included, with 1555 patients in MiHACP group and 1499 patients in MoHACP group, and the mean HCA temperature were 29.4°C and 24.8°C, respectively. Postoperative PND, TND, mortality, paraplegia, dialysis, tracheotomy, reexploration for bleeding, and chest tube drainage volume were comparable in the two groups (p > 0.05). Ventilator time, intensive care unit and in-hospital length of stay were shorter in MiHACP group (p < 0.05). Outcomes were also comparable or had some benefits in MiHACP group when subgroup analyses were conducted according to hemiarch or total arch replacement, unilateral or bilateral SACP, HCA time, emergency aortic dissection surgery, and concomitant procedure. CONCLUSION The present meta-analysis showed acceptability of MiHACP in adult aortic arch surgery. Results need to be taken with caution as moderate risk of bias and very low quality of evidence were observed in this meta-analysis. Randomized controlled trials are needed for further analysis.

Abstract
BACKGROUND Aortic arch surgery still represents a challenge, and the frozen elephant trunk (FET) allows a one-step surgery for complex aortic diseases. The aim of the study was to analyze the results of patients undergoing FET procedure for aortic arch surgery at Bordeaux University Hospital. METHODS Patients undergoing FET procedure for multisegmented aortic arch pathologies were analyzed in this single-center retrospective study. Further subgroup analyses were performed according to the degree of urgency of the operation (elective versus emergent surgery) and cerebral protection technique: bilateral selective antegrade cerebral perfusion (B-SACP) versus the unilateral one (U-SACP), regardless of the degree of urgency. RESULTS From August 2018 to August 2022, 77 consecutive patients (64.1±9.9 years, 54 males) were enrolled: 43 (55.8%) for elective surgery and 34 (44.2%) in emergency. Technical success was 100%. 30-day mortality was 15.6% (N.=12, 7% elective vs. 26.5% emergent, P=0.043). Six (7.8%) non-disabling strokes occurred (1.9% B-SACP vs. 20% U-SACP, P=0.021). Median follow-up was 1.11 years (interquartile range, 0.62-2.07). The 1-year overall survival was 81.6±4.45%. The elective group showed a survival trend when compared to the emergency one (P=0.054). However, further examination at landmark analysis elective surgery showed a better survival trend compared to emergency surgery up to 1.78 years (P=0.034), after which significance was lost (P=0.521). CONCLUSIONS Thoraflex hybrid prosthesis for FET technique demonstrated feasibility and satisfactory short-term clinical outcomes, even in emergent settings. In our practice B-SACP seems to offer better protection and less neurological complications compared to U-SACP, nevertheless further analyses are warranted.

NO Addition during Gas Oxygenation Reduces Liver and Kidney Injury during Prolonged Cardiopulmonary Bypass. PATHOPHYSIOLOGY 2023; 30:484-504. [PMID: 37873857 PMCID: PMC10594502 DOI: 10.3390/pathophysiology30040037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/09/2023] [Accepted: 10/10/2023] [Indexed: 10/25/2023] Open
Abstract
Objective. To evaluate the effect of NO added to the sweep gas of the oxygenator during cardiopulmonary bypass (CPB) on the liver and kidneys in pigs. Methods. An experiment was carried out on 10 pigs undergoing cardiac surgery using CPB. NO was added to the sweep gas of the oxygenator at a concentration of 100 ppm for the animals in the experimental group (CPB-NO, n = 5). Animals in the control group (CPB-contr, n = 5) did not receive NO in the sweep gas of the oxygenator. The CPB lasted 4 h, followed by postoperative monitoring for 12 h. To assess the injury to the liver and kidneys, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, creatinine, and neutrophil gelatinase-associated lipocalin (NGAL) were determined initially, at weaning from the CPB, and 6 and 12 h after weaning from the CPB. The glomerular filtration rate (GFR) was evaluated initially, at weaning from the CPB, and 6 and 12 h after weaning from the CPB. A pathomorphological study of the liver and kidneys was performed using semiquantitative morphometry. Results. The long four-hour period of CPB deliberately used in our experiment caused liver and kidney injury. In the CPB-contr group, an increase in the ALT concentration was found: 43 (34; 44) U/L at baseline to 82 (53; 99) U/L 12 h after CPB, p < 0.05. The AST concentration in the CPB-contr group increased from 25 (17; 26) U/L at baseline to 269 (164; 376) U/L 12 h after CPB, p < 0.05. We found no significant increase in the ALT and AST concentrations in the CPB-NO group. There were no significant differences in ALT and AST concentrations between the CPB-NO and CPB-contr groups at all the study time-points. In the CPB-contr group, an increase in the creatinine level was found from 131 (129; 133) µmol/L at baseline to 273 (241; 306) µmol/L 12 h after CPB, p < 0.05. We found no significant increase in creatinine level in the CPB-NO group. Creatinine levels in the CPB-NO group were significantly lower than in the CPB-contr group 12 h after weaning from CPB: 183 (168; 196) vs. 273 (241; 306) µmol/L; p = 0.008. The GFR in the CPB-NO group was significantly higher than in the CPB-contr group 6 h after weaning from CPB: 78.9 (77.8; 82.3) vs. 67.9 (62.3; 69.2) mL/min; p = 0.016. GFR was significantly higher in the CPB-NO group than in the CPB-contr group 12 h after weaning from CPB: 67.7 (65.5; 68.0) vs. 50.3 (48.7; 54.9) mL/min; p = 0.032. We found no significant differences between the study groups in the level of NGAL. We found several differences between the groups in the pathomorphological study. Conclusions. NO added to the sweep gas of the oxygenator reduces creatinine levels and increases GFR during prolonged CPB injury. Further research is required.

Abstract
OBJECTIVES To determine the role of adding open distal anastomosis to proximal aortic aneurysm repairs in bicuspid aortic valve (BAV) patients. METHODS Retrospective review was performed of 1132 patients at our Aortic Center between 2005 and 2019. Inclusion criteria were all patients diagnosed with a BAV who underwent proximal aortic aneurysm repair with open or clamped distal anastomosis. Exclusion criteria were patients without a BAV, age < 18 years, aortic arch diameter ≥ 4.5 cm, type A aortic dissection, previous ascending aortic replacement, ruptured aneurysm, and endocarditis. Propensity score matching in a 2:1 ratio (220 clamped: 121 open repairs) on 18 variables was performed. RESULTS Median follow-up time was 45.6 months (range 7.2-143.4 months). In the matched groups, no significant differences were observed between the respective open and clamped distal anastomosis groups for Kaplan Meier 10-year survival (86.9% vs. 92.9%; p = 0.05) and landmark survival analysis after 1 year (90.6%; vs. 93.3%; p = 0.39). Overall incidence of aortic arch-related reintervention was low (n = 3 total events). In-hospital complications were not significantly different in the open with respect to the clamped repair group, including in-hospital mortality (2.5% vs. 0.5%; p = 0.13) and stroke (0% vs. 0.9%; p = 0.54). In multivariable analysis, open distal anastomosis repair was not associated with long-term mortality (Hazard Ratio (HR) 1.98; p = 0.06). CONCLUSION We found no significant inter-group differences in survival, reintervention, or in-hospital complication rates, with low rates of mortality, and aortic arch-related reintervention, suggesting adding open distal anastomosis may not provide benefit in BAV patients undergoing proximal aortic aneurysm repairs.

Abstract
BACKGROUND AND AIM Pulmonary hypertension (PH) is frequently associated with cardiovascular surgery and is a common complication that has been observed after surgery utilizing cardiopulmonary bypass (CPB). The purpose of this review is to explain the characteristics of PH, the mechanisms of PH induced by cardiac surgery and CPB, treatments for postoperative PH, and future directions in treating PH induced by cardiac surgery and CPB using up-to-date findings. METHODS The PubMed database was utilized to find published articles. RESULTS There are many mechanisms that contribute to PH after cardiac surgery and CPB which involve pulmonary vasomotor dysfunction, cyclooxygenase, the thromboxane A2 and prostacyclin pathway, the nitric oxide pathway, inflammation, and oxidative stress. Furthermore, there are several effective treatments for postoperative PH within different types of cardiac surgery. CONCLUSIONS By possessing a deep understanding of the mechanisms that contribute to PH after cardiac surgery and CPB, researchers can develop treatments for clinicians to use which target the mechanisms of PH and ultimately reduce and/or eliminate postoperative PH. Additionally, learning about the most up-to-date studies regarding treatments can allow clinicians to choose the best treatments for patients who are undergoing cardiac surgery and CPB.

Abstract
Potassium homeostasis affects cardiac rhythm and contractility, along with vascular reactivity and vascular smooth muscle proliferation. This chapter will focus on potassium dynamics during and after cardiac surgery involving cardioplegic arrest and cardiopulmonary bypass (CPB). Hyperkalemic, hypothermic solutions are frequently used to induce cardioplegic arrest and protect the heart during cardiac surgery involving CPB. Common consequences of hyperkalemic cardioplegic arrest and reperfusion include microvascular dysfunction involving several organ systems and myocardial dysfunction. Immediately after CPB, blood potassium levels often drop precipitously due to a variety of factors, including CPB -induced electrolyte depletion and frequent, long-term administration of insulin during and after surgery. Meanwhile, some patients with pre-existing kidney dysfunction may experience postoperative hyperkalemia following cardioplegia. Any degree of postoperative hyper/hypokalemia significantly elevates the risk of cardiac arrythmias and subsequent myocardial failure. Therefore, proper management of blood potassium levels during and after cardioplegia/CPB is crucial for optimizing patient outcomes following cardiac surgery.

Long-term outcome of hemiarch replacement in a proximal aortic aneurysm repair: analysis of over 1000 patients. Eur J Cardiothorac Surg 2022; 62:6521305. [PMID: 35134153 PMCID: PMC9257789 DOI: 10.1093/ejcts/ezab571] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 11/29/2021] [Accepted: 01/26/2022] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES The aim of this study was to investigate the impact of hemiarch replacement in patients undergoing an open repair of proximal thoracic aortic aneurysm without arch aneurysm. METHODS A retrospective review was performed on 1132 patients undergoing proximal aortic aneurysm repair at our Aortic Center between 2005 and 2019. Inclusion criteria were all patients undergoing root or ascending aortic aneurysm repair with or without hemiarch replacement. Exclusion criteria were age <18 years, aortic arch diameter ≥4.5 cm, type A aortic dissection, previous ascending aortic replacement, ruptured aneurysm and endocarditis. Propensity score matching in a 2:1 ratio (573 non-hemiarch: 288 hemiarch) on 19 baseline characteristics was performed. The median follow-up time was 46.8 months (range 0.1-170.4 months). RESULTS Hemiarch patients had significantly lower 10-year survival in the matched cohort (hemiarch 73.8%; 66.9-81.4%; vs non-hemiarch 86.5%; 81.1-92.3%; P < 0.001), driven by higher in-hospital mortality rate (4% vs 1%; P < 0.001). Cumulative incidence of aortic arch reintervention rates at 10 years was similarly low (hemiarch 1.0%; 0-2.5% vs non-hemiarch 1.3%; 0-2.6%, P = 0.615). Multivariate analysis with hazard ratios of the overall cohort showed hemiarch as an independent factor associated with long-term mortality (2.16; 1.42-3.27; P < 0.001) but not with aortic arch reintervention (0.76; 0.14-4.07, P = 0.750). CONCLUSIONS Hemiarch repair may be associated with higher short-term mortality compared to non-hemiarch. Arch reintervention was rare after a repair of proximal thoracic aortic aneurysm without arch aneurysm. Our data call for larger and prospective studies to further delineate the utility of hemiarch repair in proximal aortic surgery.

Association between Duration of Deep Hypothermic Circulatory Arrest and Surgical Outcome in Patients with Acute Type A Aortic Dissection: A Large Retrospective Cohort Study. J Clin Med 2022; 11:jcm11030644. [PMID: 35160094 PMCID: PMC8836663 DOI: 10.3390/jcm11030644] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 01/17/2022] [Accepted: 01/26/2022] [Indexed: 02/01/2023] Open
Abstract
(1) Background: Deep hypothermic circulatory arrest (DHCA) with selective antegrade cerebral perfusion (ACP) is an established cerebral protection technique for the conduction of complex surgical procedures involving the aortic arch. It is controversial whether the duration of DHCA is associated with adverse outcome in patients with acute type A aortic dissection (AAAD). Our goal was to investigate whether DHCA time was associated with surgical outcome in patients undergoing a surgical treatment of AAAD. (2) Methods: A total of 410 patients were divided into two groups based on the DHCA time less than 60 min and equal to or longer than 60 min. (3) Results: Patients with longer DHCA times were significantly younger (p = 0.001). Intraoperatively, complex procedures with aortic arch surgery were more common in patients with longer DHCA times (p < 0.001). Accordingly, cardiopulmonary bypass (p < 0.001), cross-clamping (p < 0.001) and DHCA times (p < 0.001) were significantly longer in this group. Postoperatively, only the duration of mechanical ventilation (p < 0.001) and the rate of tracheotomy were significantly higher in these patients. Thirty-day mortality was satisfactory for both groups (p = 0.746). (4) Conclusions: Our results showed that improvements in perioperative management including ACP allow for the successful performance of surgical treatment of AAAD under DHCA with a duration of even longer than 60 min.

Abstract
Objective Deep hypothermic circulatory arrest (DHCA) in aortic surgery is associated
with morbidity and mortality despite evolving strategies. With the advent of
antegrade cerebral perfusion (ACP), moderate hypothermic circulatory arrest
(MHCA) was reported to have better outcomes than DHCA. There is no
standardised guideline or consensus regarding the hypothermic strategies to
be employed in open aortic surgery. Meta-analysis was performed comparing
DHCA with MHCA + ACP in patients having aortic surgery. Methods A systematic review of the literature was undertaken. Any studies with DHCA
versus MHCA + ACP in aortic surgeries were selected according to specific
inclusion criteria and analysed to generate summative data. Statistical
analysis was performed using STATS Direct. The primary outcomes were
hospital mortality and post-operative stroke. Secondary outcomes were
cardiopulmonary bypass time (CPB), post-operative blood transfusion, length
of ICU stay, respiratory complications, renal failure and length of hospital
stay. Subgroup analysis of primary outcomes for Arch surgery alone was also
performed. Results Fifteen studies were included with a total of 5869 patients. There was
significantly reduced mortality (Pooled OR = +0.64, 95% CI = +0.49 to +0.83;
p = 0.0006) and stroke rate (Pooled OR = +0.62, 95%
CI = +0.49 to +0.79; p < 0.001) in the MHCA group. MHCA
was associated significantly with shorter CPB times, shorter duration in
ICU, less pulmonary complications, and reduced rates of sepsis. There was no
statistical difference between the two groups in terms of circulatory arrest
times, X-Clamp times, total operation duration, transfusion requirements,
renal failure and post-op hospital stay. Conclusion MHCA + ACP are associated with significantly better post-operative outcomes
compared with DHCA for both mortality and stroke and majority of the
secondary outcomes.

Abstract
Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are involved in the mechanism underlying cerebral dysfunction after deep hypothermic circulatory arrest (DHCA), although the exact details have not been elucidated. To explore the expression profiles of lncRNAs and miRNAs in DHCA cerebral injury, we determined the lncRNA, miRNA and mRNA expression profiles in the cerebral cortex of DHCA and sham rats. First, a rat model of DHCA was established, and high-throughput sequencing was performed to analyze the differentially expressed RNAs (DERNAs). Then, the principal functions of the significantly deregulated genes were identified using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Expression networks (lncRNAs-miRNAs-mRNAs and transcription factors (TFs)-miRNAs-mRNAs) were also established. Finally, the expression of DERNAs was confirmed by quantitative real-time PCR (RT-qPCR). We identified 89 lncRNAs, 45 miRNAs and 59 mRNAs between the DHCA and sham groups and constructed a comprehensive competitive endogenous RNAs (ceRNAs) network. A TF-miRNA-mRNA regulatory network was also established. Finally, we predicted that Lcorl-miR-200a-3p-Ttr, BRD4-Ccl2 and Ep300-miR-200b-3p-Tmem72 may participate in the pathogenesis of DHCA cerebral injury.

Abstract
OBJECTIVES Acute cholecystitis is a complication in critically ill patients. However, a few studies have described its incidence, risk factors, and mortality in patients who underwent cardiovascular surgery. We investigated the incidence, perioperative predictors, and clinical features of acute cholecystitis after cardiovascular surgery. METHODS This retrospective cohort study examined 7013 patients who underwent cardiovascular surgery between October 2000 and March 2019 at a tertiary care hospital. We collected preoperative, intraoperative, and postoperative data from our database and electronic medical records. The primary outcome was the incidence of postoperative cholecystitis until hospital discharge. A multivariable logistic regression analysis to estimate perioperative predictors of acute cholecystitis was conducted. We described the clinical characteristics of patients complicated with acute cholecystitis. RESULTS Among the 7013 patients, 51 (0.7%) developed acute cholecystitis. Logistic regression analysis found that circulatory arrest (odds ratio [OR] 1.97; 95% confidence interval [CI] 1.04-3.74; P = 0.037) and intraoperative massive transfusion (OR 2.03; 95% CI 1.03-4.01; P = 0.041) were associated with the incidences of cholecystitis. In-hospital mortality was significantly higher in the cholecystitis group than in the non-cholecystitis group (13.7% vs 3.9%, P = 0.004). Aortic disease was more frequent in the cholecystitis group (54.9% vs 38.6%, P = 0.021). The median time of acute cholecystitis onset from surgery was 12.5 days (interquartile range 7.0-27.75). Twenty-six patients (51.0%) developed asymptomatic cholecystitis. CONCLUSIONS Approximately 1% of patients who underwent cardiovascular surgery developed postoperative cholecystitis; half of them were asymptomatic. Since cholecystitis is associated with high mortality, it is a complication after cardiovascular surgery that needs to be considered.

Abstract
OBJECTIVES The impact of hypothermic circulatory arrest (HCA) temperature on postoperative acute kidney injury (AKI) has not been evaluated. This study examined the association between circulatory arrest temperatures and AKI in patients undergoing proximal aortic surgery with HCA. METHODS A total of 759 consecutive patients who underwent proximal aortic surgery (ascending ± valve ± root) including arch replacement requiring HCA between July 2005 and December 2016 were identified from a prospectively maintained institutional aortic surgery database. The primary outcome was AKI as defined by Risk, Injury, Failure, Loss, End Stage Renal Disease (ESRD) criteria. The association between minimum nasopharyngeal (NP) and bladder temperatures during HCA and postoperative AKI was assessed, adjusting for patient-level factors using multivariable logistic regression. RESULTS A total of 85% (n = 645) of patients underwent deep hypothermia (14.1-20.0°C), 11% (n = 83) low-moderate hypothermia (20.1-24.0°C) and 4% (n = 31) high-moderate hypothermia (24.1-28.0°C) as classified by NP temperature. When analysed by bladder temperature, 59% (n = 447) underwent deep hypothermia, 22% (n = 170) low-moderate, 16% (n = 118) high-moderate and 3% mild (n = 24) (28.1-34.0°C) hypothermia. The median systemic circulatory arrest time was 17 min. The incidence of AKI did not differ between hypothermia groups, whether analysed using minimum NP or bladder temperature. In the multivariable analysis, the association between degree of hypothermia and AKI remained non-significant whether analysed as a categorical variable (hypothermia group) or as a continuous variable (minimum NP or bladder temperature) (all P > 0.05). CONCLUSIONS In patients undergoing proximal aortic surgery including arch replacement requiring HCA, degree of systemic hypothermia was not associated with the risk of AKI. These data suggest that moderate hypothermia does not confer increased risk of AKI for patients requiring circulatory arrest, although additional prospective data are needed.

Contemporary Trends and Risk Factors of Hemodynamic and Myocardial Mechanics Derived by the Pressure Recording Analytical Method After Pediatric Cardiopulmonary Bypass. Front Cardiovasc Med 2021; 8:687150. [PMID: 34355027 PMCID: PMC8330813 DOI: 10.3389/fcvm.2021.687150] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 06/25/2021] [Indexed: 01/14/2023] Open
Abstract
Objective: Adverse factors of postoperative hemodynamic and myocardial performance remain largely unexplored in children with congenital heart disease following cardiopulmonary bypass due to technical limitations. Pressure recording analytical method (PRAM) is a continuous hemodynamic and myocardial performance monitoring technique based on beat-to-beat arterial pressure waveform. Using PRAM, we examined the temporal trends and adverse factors, in clinical management, of these performances. Methods: We monitored blood pressure, cardiac index, cardiac cycle efficiency (CCE), dP/dTmax, and systematic vascular resistance index in 91 children (aged 186 ± 256 days) during their first 48 h after cardiopulmonary bypass. Above parameters, inotropic and vasoactive drug dosages, and serum lactate were recorded 3-hourly. NT-proBNP was measured daily. Results: CCE and dP/dTmax gradually increased (Ps < 0.0001), while systematic vascular resistance index, diastolic blood pressure and inotrope dosages decreased (Ps < 0.0001) over time. Cardiac index, systolic blood pressure, and heart rate did not change significantly (Ps ≥ 0.231). Patients undergoing deep hypothermic circulatory arrest had significantly higher heart rate and lower CCE (Ps ≤ 0.006) over time. Multivariate analyses indicated that epinephrine dose significantly correlated with systolic blood pressure, cardiac index, CCE, and dP/dTmax after polynomial transformation, with the peak ranging from 0.075 to 0.097. Conclusions: Systemic hemodynamic and myocardial performance gradually improved in the first 48 h after cardiopulmonary bypass without the “classic” nadir at 9–12 h. Deep hypothermic circulatory arrest and higher epinephrine doses were adversely associated with these performances. CCE, rather than cardiac index or other common-used parameters, was the most sensitive and consistent indicator.

Abstract
OBJECTIVES Cardiac surgery using cardiopulmonary bypass frequently provokes a systemic inflammatory response syndrome. This can lead to the development of low cardiac output syndrome (LCOS). Both of these can affect morbidity and mortality. This study is a systematic review of the impact of gaseous nitric oxide (gNO), delivered via the cardiopulmonary bypass (CPB) circuit during cardiac surgery, on post-operative outcomes. It aims to summarise the evidence available, to assess the effectiveness of gNO via the CPB circuit on outcomes, and highlight areas of further research needed to develop this hypothesis. METHODS A comprehensive search of Pubmed, Embase, Web of Science and the Cochrane Library was performed in May 2020. Only randomised control trials (RCTs) were considered. RESULTS Three studies were identified with a total of 274 patients. There was variation in the outcomes measures used across the studies. These studies demonstrate there is evidence that this intervention may contribute towards cardioprotection. Significant reductions in cardiac troponin I (cTnI) levels and lower vasoactive inotrope scores were seen in intervention groups. A high degree of heterogeneity between the studies exists. Meta-analysis of the duration of mechanical ventilation, length of ICU stay and length of hospital stay showed no significant differences. CONCLUSION This systematic review explored the findings of three pilot RCTs. Overall the hypothesis that NO delivered via the CPB circuit can provide cardioprotection has been supported by this study. There remains a significant gap in the evidence, further high-quality research is required in both the adult and paediatric populations.

Abstract
The gastrointestinal (GI) system, is most vulnerable to hypoperfusion among the splanchnic organs. Disturbed perfusion of the mesenteric area may lead to GI dysfunction, cause further injury to the patients and even vital outcomes. However, due to the limitation of detection methods, the hemodynamic influences on mesenteric blood flow in clinical practice are not fully understood. By elucidating the underlying mechanisms, we may be able to recognize disturbed GI perfusion and eventually GI dysfunction at an early phase. Thus, in this review, we will focus on situations where mesenteric blood flow is disturbed due to hemodynamic causes in shock conditions, and the present research status will be discussed. English language articles published before 2020 were identified through a computerized PubMed search using the terms "mesenteric, gastrointestinal, intestinal, splanchnic, blood flow, perfusion" and the cofactors. Relevant publications were retrieved and scanned for additional sources. There were few clinical trials focusing on mesenteric blood flow in shock patients. Most were animal experiments. Based on the best current evidence from these sources, we described the major influences on mesenteric blood flow in the context of physiologic accommodation, disease-related effects and the consequences of medical interventions related to shock conditions. During circulatory shock, sepsis, and medical interventions related to shock treatment, mesenteric blood flow changes and shows different features. We need to carefully consider these issues when making medical decisions, and more work needs to be done on early detection of GI hypoperfusion and its accurate correlation with GI dysfunction.

Front Cardiovasc Med 2021; 8:638420. [PMID: 33937356 PMCID: PMC8081908 DOI: 10.3389/fcvm.2021.638420] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 03/17/2021] [Indexed: 11/13/2022] Open
Abstract
Background: This study employed three surgical techniques: total arch replacement (TAR) with frozen elephant trunk (FET), aortic balloon occlusion technique (ABO) and hybrid aortic arch repair (HAR) on patients with type I aortic dissection in Fuwai Hospital, aiming to compare the early outcomes of these surgical armamentariums. Methods: From January 2016 to December 2018, an overall 633 patients (431 of TAR+FET, 122 of HAR, and 80 of ABO) with type I aortic dissection were included in the study. Thirty-day mortality, stroke, paraplegia, re-exploration for bleeding, and renal replacement therapy were compared using the matching weight method (MWM). Results: After MWM process, the baseline characteristics were comparable among three TAR groups. It showed that ABO group had the longest cardiopulmonary bypass (p < 0.001) and aortic cross-clamp time (p < 0.001), while the operation time was longest in the HAR group (p = 0.039). There was no significant difference in 30-day mortality among groups (p = 0.783). Furthermore, the incidence of stroke (p = 0.679), paraplegia (p = 0.104), re-exploration for bleeding (p = 0.313), and CRRT (p = 0.834) demonstrated no significant difference. Of note, no significant differences were found regarding these outcomes even before using MWM. Conclusions: Based on the early outcomes, the three TAR approaches were equally applicable to type I aortic dissection. We may choose the specific procedure relatively flexibly according to patient status and surgeon's expertise. Importantly, long-term investigations are warranted to determine whether above approaches remain to be of equivalent efficacy and safety.

Abstract
OBJECTIVES We aimed to compare the short- and midterm results of perfusion strategies used for arch reconstruction surgery. MATERIAL AND METHODS One hundred and seventy-three consecutive patients who underwent aortic arch reconstruction surgery for transverse arcus hypoplasia between January 2011 and February 2020 were retrospectively analyzed. The patients were divided into two groups, as beating heart (BH) group and cardiac arrest (CA) group. RESULTS The CA group comprised 60 (35%) patients and the remaining 113 (65%) patients were in the BH group. The median age of the patients was 30 (interquartile range: 18-95) days. The incidences of acute renal failure (ARF) and delayed sternal closure were higher in the CA group (p = .05, <.001, respectively). Balloon angioplasty was performed in 5 (2%) patients and reoperation was performed in 11 (6%) patients due to restenosis. There were no statistically significant differences between the two groups in terms of reoperation or reintervention rates (p = .44 and .34, respectively). CONCLUSIONS Both strategies were associated with satisfactory midterm prevention of reintervention and reoperation. Given the lower incidence of ARF and delayed sternal closure in the postoperative period and similar midterm outcomes, we believe that the BH strategy is preferable.

Abstract
OBJECTIVE Nitric oxide (NO) plays several protective roles in ischemia/reperfusion (I/R) injury. Neonates undergoing the Norwood procedure are subject to develop I/R injury due to the immaturity of their organs and the potential need to interrupt or decrease systemic flow during surgery. We hypothesized that NO administration during cardiopulmonary bypass (CPB) ameliorates the I/R and could help the postoperative recovery after the Norwood procedure. METHODS Twenty-four neonates who underwent a Norwood procedure were enrolled in a prospective randomized blinded controlled trial to receive NO (12 patients) or placebo (12 patients) into the oxygenator of the CPB circuit during the Norwood procedure. Markers of I/R injury were collected at baseline (T0), after weaning from CPB before modified ultrafiltration (T1), after modified ultrafiltration (T2), and at 12 hours (T3) and 24 hours (T4) after surgery, and they were compared between both groups, as well as other postoperative clinical variables. RESULTS There was no difference in age, weight, anatomical diagnosis, CPB, and aortic cross-clamp time between both groups. Troponin levels were lower in the study group at T1 (0.62 ± 58 ng/mL vs 0.87 ± 0.58 ng/mL, P = .31) and became significantly lower at T2 (0.36 ± 0.32 ng/mL vs 0.97 ± 0.48 ng/mL, P = .009).There were no significant differences between both groups for all other markers. Despite a lower troponin level, there was no difference in inotropic scores or ventricular function between both groups. Time to start diuresis, time to sternal closure and extubation, and intensive care unit and hospital stay were not different between both groups. CONCLUSION Systemic administration of NO during the Norwood procedure has myocardial protective effects (lower Troponin levels) but we observed no effect on postoperative recovery. Larger sample size may be needed to show clinical differences.

Abstract
The effect of temperature on cerebral injury during hypothermic circulatory arrest (HCA) has never been specifically studied. This study aimed to compare the effects of two different temperatures used for HCA on the degree of brain injury in pig models. Thirteen pigs were randomly assigned to a deep hypothermic circulatory arrest (DHCA) group (n = 5), moderate hypothermic circulatory arrest (MHCA) group (n = 5), or control group (n = 3). No significant differences in immunohistochemical assay results, including Bax, Bcl-2, and Caspase 3 staining, and a TUNEL assay, were observed between the DHCA and MHCA groups. Furthermore, no significant difference was found for biomarkers of brain injury (Soluble protein-100B) between the two experimental groups. Similarly, no significant difference was observed in the trend of changes in inflammatory factors, including tumor necrosis factor-α, interleukin (IL)-2, and IL-6, between the two groups (p > 0.05). However, coagulation factors, including FXI and FVII, were different between the DHCA and MHCA groups (p < 0.05). Therefore, it can be concluded that MHCA does not increase the risk of cerebral injury. Considering the adverse effects of DHCA on the coagulation system, MHCA is more suitable for current clinical practice.

Abstract
BACKGROUND Use of antegrade cerebral perfusion (ACP) as an alternative neuroprotection strategy to deep hypothermic circulatory arrest (DHCA) in the setting of cardiopulmonary bypass in neonates has become a common approach, although the value of ACP over DHCA remains highly debated. This study investigated the disruption to neonatal brain homeostasis by DHCA and ACP. METHODS Neonatal pigs (7 days old) undergoing bypass were assigned to 4 groups: DHCA at 18°C and ACP at 18°, 25°, and 32° for 45 minutes (n = 6 per group). ACP was initiated through the innominate artery and maintained at 40 mL/kg/min. After bypass, all animals were maintained sedated and intubated for 24 hours before being euthanized. Brain subventricular zone tissues were analyzed for histologic injury by assessing apoptosis and neural homeostasis (Nestin). RESULTS Histologic examination showed no significant ischemic/hypoxic neuronal death at any cooling temperature among the 4 treatment groups. However, we detected a significantly higher apoptotic rate in DHCA compared with ACP at 18°C (P = .003-.017) or 25°C (P = .012-.043), whereas apoptosis at 32°C was not different from DHCA. Of note, we identified increased Nestin expression in the DHCA group compared with all ACP groups (P range = .011-.041). CONCLUSIONS Neonatal piglet ACP at 18° or 25°C provides adequate protection from increased brain cellular apoptosis. In contrast to ACP, however, DHCA induces brain Nestin expression, indicating activation of neural progenitor cells and the potential of altering neonatal neurodevelopmental progression. DHCA has potential to more profoundly disrupt neural homeostasis than does ACP.

Abstract
Abstract
OBJECTIVES
The aim of this study was to investigate the impact of various brain perfusion techniques and nadir temperature cooling strategies on outcomes after aortic arch repair in a contemporary, multicentre cohort.
METHODS
A total of 2520 patients underwent aortic arch repair with hypothermic circulatory arrest (HCA) between 2002 and 2018 in 11 centres of the Canadian Thoracic Aortic Collaborative. Primary outcomes included mortality; stroke; a composite of mortality or stroke; and a Society of Thoracic Surgeons-defined composite (STS-COMP) end point for mortality or major morbidity including stroke, reoperation, renal failure, prolonged ventilation and deep sternal wound infection. Multivariable logistic regression and propensity score matching were performed for cerebral perfusion and nadir temperature practices.
RESULTS
Antegrade cerebral perfusion was found on multivariable analysis to be protective against mortality [odds ratio (OR) 0.64, 95% confidence interval (CI) 0.48–0.86; P = 0.005], stroke (OR 0.55, 95% CI 0.37–0.81; P = 0.006), composite of mortality or stroke (OR 0.57, 95% CI 0.45–0.72; P = 0.0001) and STS-COMP (OR 0.53, 95% CI 0.41–0.67; P < 0.0001), as compared to HCA alone. Retrograde cerebral perfusion yielded similar outcomes as compared to antegrade cerebral perfusion. When compared to HCA with nadir temperature <24°C, a propensity score analysis of 647 matched pairs identified nadir temperature ≥24°C as predictor of lower mortality (OR 0.62, 95% CI 0.40–0.98; P = 0.04), stroke (OR 0.51, 95% CI 0.31–0.84; P = 0.008), composite of mortality or stroke (OR 0.62, 95% CI 0.43–0.89; P = 0.01) and STS-COMP (OR 0.64, 95% CI 0.49–0.85; P = 0.002).
CONCLUSIONS
Antegrade cerebral perfusion and nadir temperature ≥24°C during HCA for aortic arch repair are predictors of improved survival and neurological outcomes.

OBJECTIVES The goal was to investigate the prevalence of acute kidney injury (AKI) after total arch replacement with frozen elephant trunk procedure, which was achieved by antegrade cerebral perfusion and moderate hypothermic circulatory arrest (MHCA) or deep hypothermic circulatory arrest (DHCA) among patients with type A aortic dissection. METHODS Overall, 627 adult type A aortic dissection patients who underwent total arch replacement with frozen elephant trunk from January 2013 until December 2016 at Fuwai Hospital were divided into the DHCA (14.1-20.0°C) and MHCA (20.1-28.0°C) groups. Postoperative AKI as the primary outcome was compared using propensity-matched scoring. RESULTS Overall, 340 (54.2%) and 287 (45.8%) patients underwent DHCA and MHCA, respectively. The overall incidence of AKI was 75.4%. Age [odds ratio (OR) 1.02, 95% confidence interval (CI) 1.00-1.04; P = 0.022], body mass index (OR 1.06, 95% CI 1.01-1.12; P = 0.016), cardiopulmonary bypass duration (OR 1.01, 95% CI 1.00-1.01; P = 0.003) and hypertension history (OR 1.76, 95% CI 1.14-2.70; P = 0.010) were identified as independent risk factors for AKI onset with multivariable analysis. Postoperative AKI was not significantly different between the DHCA and MHCA groups regardless of the overall or propensity-matched cohort (overall data: P = 0.17; propensity score data: P = 0.88). Patients with MHCA experienced higher rates of postoperative stroke after propensity score analysis (DHCA 0.9% vs MHCA 3.7%; P = 0.034). CONCLUSIONS MHCA was not superior to DHCA in decreasing postoperative AKI. Thus, MHCA should not definitively replace DHCA.

Utilization of inhaled nitric oxide after surgical repair of truncus arteriosus: A multicenter analysis. CONGENIT HEART DIS 2019; 14:1078-1086. [PMID: 31713327 DOI: 10.1111/chd.12849] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Revised: 08/14/2019] [Accepted: 09/11/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND Elevated pulmonary vascular resistance (PVR) is common following repair of truncus arteriosus. Inhaled nitric oxide (iNO) is an effective yet costly therapy that is frequently implemented postoperatively to manage elevated PVR. OBJECTIVES We aimed to describe practice patterns of iNO use in a multicenter cohort of patients who underwent repair of truncus arteriosus, a lesion in which recovery is often complicated by elevated PVR. We also sought to identify patient and center factors that were more commonly associated with the use of iNO in the postoperative period. DESIGN Retrospective cohort study. SETTING 15 tertiary care pediatric referral centers. PATIENTS All infants who underwent definitive repair of truncus arteriosus without aortic arch obstruction between 2009 and 2016. INTERVENTIONS Descriptive statistics were used to demonstrate practice patterns of iNO use. Bivariate comparisons of characteristics of patients who did and did not receive iNO were performed, followed by multivariable mixed logistic regression analysis using backward elimination to identify independent predictors of iNO use. MAIN RESULTS We reviewed 216 patients who met inclusion criteria, of which 102 (46%) received iNO in the postoperative period: 69 (68%) had iNO started in the operating room and 33 (32%) had iNO initiated in the ICU. Median duration of iNO use was 4 days (range: 1-21 days). In multivariable mixed logistic regression analysis, use of deep hypothermic circulatory arrest (odds ratio: 3.2; 95% confidence interval: 1.2, 8.4) and center (analyzed as a random effect, p = .02) were independently associated with iNO use. CONCLUSIONS In this contemporary multicenter study, nearly half of patients who underwent repair of truncus arteriosus received iNO postoperatively. Use of iNO was more dependent on individual center practice rather than patient characteristics. The study suggests a need for collaborative quality initiatives to determine optimal criteria for utilization of this important but expensive therapy.

Abstract
OBJECTIVES Double-arterial cannulation enables cerebral perfusion and lower body perfusion during aortic arch reconstruction. The aim of this study was to analyse and report our experience of using this cannulation and perfusion technique on paediatric patients. METHODS A retrospective single-centre study was carried out on 407 consecutive paediatric patients who underwent an aortic arch reconstruction under double-arterial cannulation between 2003 and 2015. The median age of the patients at surgery was 8 (range 2-5570) days, and body weight was 3.3 (range 1.8-60) kg. All operations were performed through standard median sternotomy. One arterial cannula was inserted into the innominate artery and the second one into the supradiaphragmatic descending aorta. Primary end points were 30-day mortality, acute renal failure requiring dialysis and time until lactate level decreased to ≤2 mmol/l postoperatively. RESULTS We found an in-hospital mortality of 8.6%. Lethal incident was not associated with the cannulation method, and 1 intraoperative lesion of the descending aorta could be repaired immediately. The median lactate level of the patients on arrival at the intensive care unit was 3.5 mmol/l [quartile (Q)1: 2.3-Q3: 4.7] and creatinine was 0.48 mg/100 ml (Q1: 0.40-Q3: 0.58). The longest duration until the lactate level decreased to ≤ 2 mmol/l was found in the group of 264 univentricular patients (median 11 h, Q1: 6-Q3: 24). Seven (1.7%) patients of the whole cohort required peritoneal dialysis postoperatively. CONCLUSIONS Double-arterial cannulation is a simple and safe method for perfusing the brain and the lower parts of the body during aortic arch reconstruction. Perioperative survival and freedom from procedure-related complications in this demanding patient population are encouraging.

Deep Hypothermic Circulatory Arrest Does Not Show Better Protection for Vital Organs Compared with Moderate Hypothermic Circulatory Arrest in Pig Model. BIOMED RESEARCH INTERNATIONAL 2019; 2019:1420216.

Abstract
Background Continued debates exist regarding the optimal temperature during hypothermic circulatory arrest in aortic arch repair for patients with type A aortic dissection. This study seeks to examine whether the use of moderate hypothermic circulatory arrest in a pig model provides comparable vital organ protection outcomes to the use of deep hypothermic circulatory arrest. Methods Thirteen pigs were randomly assigned to 30 minutes of hypothermic circulatory arrest without cerebral perfusion at 15°C (n = 5), 25°C (n = 5), and a control group (n = 3). The changes in standard laboratory tests and capacity for protection against apoptosis in different vital organs were monitored with different temperatures of hypothermic circulatory arrest management in pig model to determine which temperature was optimal for hypothermic circulatory arrest. Results There were no significant differences in the capacity for protection against apoptosis in vital organs between 2 groups (p > 0.05, respectively). Compared with the moderate hypothermic circulatory arrest group, the deep hypothermic circulatory arrest group had no significant advantages in terms of the biologic parameters of any other organs (p > 0.05). Conclusions Compared with deep hypothermic circulatory arrest, moderate hypothermic circulatory arrest is a moderate technique that has similar advantages with regard to the levels of biomarkers of injury and capacity for protection against apoptosis in vital organs.

Abstract
OBJECTIVE To simplify Foley catheter-assisted thrombectomy to a six-step approach and determine the feasibility and results of this technique for renal cell carcinoma (RCC) with a Mayo level II to IV tumor thrombus (TT). METHODS The surgical records of patients with RCC with a Mayo level II to IV TT treated in our hospital were retrospectively reviewed. Fifteen patients who underwent radical nephrectomy and thrombectomy with a Foley catheter-assisted procedure were included. Epidemiological and clinicopathological features, operation-related variables, and outcomes were evaluated. RESULTS The TTs in all 15 patients were successfully retracted by the Foley catheter. The mean operation time was 420.1 ± 108.9 minutes. The mean intraoperative blood loss and perioperative red blood cell transfusion volumes were 1846.7 ± 1467.8 and 1288.7 ± 1060.6 mL, respectively. Five patients had perioperative complications. The median follow-up time was 9 (range, 0-34) months, and four patients died of the disease. CONCLUSIONS Simplification of Foley catheter-assisted thrombectomy to a six-step approach results in the probability of avoiding thoracotomy or cardiopulmonary bypass to a certain degree and is associated with fewer complications, less blood loss, and less perioperative red blood cell transfusion. However, experienced surgeons and multidisciplinary cooperation are still needed.

Abstract
OBJECTIVE The study objective was to determine whether hybrid aortic repair yields superior outcomes compared with the conventional surgical approach for DeBakey type I aortic dissection. METHODS A retrospective analysis of patients with DeBakey type I dissection admitted to Fuwai Hospital between January 2010 and December 2016 showed that 815 patients (86.9%) underwent open total arch replacement with frozen elephant trunk (frozen elephant trunk group) and 122 (13.1%) underwent hybrid aortic arch repair without deep hypothermic circulatory arrest (hybrid group). We selected 109 pairs of patients for propensity score matching. Outcomes included early postoperative death, a composite of complications, dissected aorta remodeling, long-term survival, and freedom from reoperation. RESULTS Early mortality and complication rates were lower in the hybrid group, but the difference was not statistically significant (9.2% vs 17.4%, P = .073; 15.6% vs 25.7%, P = .066). The rates of postoperative renal insufficiency was significantly lower in the hybrid group than in the frozen elephant trunk group (22.9% vs 38.5%, P = .013); liver insufficiency and paraplegia were significantly lower in the hybrid group than in the frozen elephant trunk group (20.2% vs 33.9%, P = .022; 0% vs 6.4%, P = .014). After matched, the 1-year, 3-year, and 5-year survivals were 87.6%, 86.3%, and 82.2%, respectively, in the hybrid group and 80.7%, 76.5%, and 74.6% (P = .071), respectively, in the frozen elephant trunk group. CONCLUSIONS Hybrid aortic arch repair is a viable alternative treatment for patients with DeBakey type I aortic dissection, which improves outcomes and promotes remodeling of the dissected thoracic aorta.

Abstract
BACKGROUND Apoptosis is a cellular mechanism contributing to cardiac surgery using cardiopulmonary bypass (CPB)-induced lung injury. The ubiquitous PI3K/Akt pathway regulates proliferation, apoptosis and differentiation by controlling a broad range of target proteins including NF-κB and GSK-3β. The roles of the PI3K/Akt/NF-κB and PI3K/Akt/GSK-3β pathways in CPB-related lung injury are unclear. METHODS Seventy-two male Sprague-Dawley rats were assigned into sham, CPB, Wortmannin (Wtn) and insulin-like growth factor-I (IGF-I) groups (n = 18, each). Six subjects per group were evaluated at each of three time points: Prior to CPB (T1); opening of the left hilus pulmonis (T2); and 90 min after CPB (T3). Arterial blood specimens were obtained at each time point to test respiratory and oxygenation indices. Left lung tissues were processed for H&E and TUNEL staining. Western blot was employed to evaluate protein levels and activities of Akt, phospho-Akt (p-Akt), GSK-3β, phospho-GSK-3β (p-GSK-3β) and nuclear NF-κB. RESULTS Lung ischemia/reperfusion and CPB caused notable lung injury, as evidenced by lung functional decline and pathological deterioration, accompanied by increases in apoptosis and expression levels of p-Akt, p-GSK-3β and nuclear NF-κB in lungs (all P < 0.05 vs. Sham). At T3, Wtn-treated CPB subjects showed worsened lung function and pathological lung structures, as well as apoptosis in lungs (all P < 0.05 vs. CPB); additionally, Wtn inhibited Akt phosphorylation and slightly, but significantly increased expression of nuclear NF-κB (both P < 0.001 vs. CPB). Conversely, treatment of subjects with IGF-I increased Akt phosphorylation (P < 0.001 vs. CPB), inhibited expression of nuclear NF-κB (P = 0.008 vs. CPB), improved lung function and tissue morphology (both P < 0.05 vs. CPB), and reduced apoptosis in lungs (P < 0.001 vs. CPB). Neither Wtn nor IGF-I did alter GSK-3β phosphorylation levels (P = 0.836 and P = 0.669 vs. CPB, respectively). CONCLUSION The PI3K/Akt/NF-κB pathway played a role in CPB-related lung injury, possibly through mediating apoptosis in lungs. GSK-3β, a signaling effector that also participated in CPB-induced apoptosis in lungs, but was not regulated by the PI3K/Akt pathway in this context.

Abstract
Aortic arch surgery in patients with acute aortic dissection is frequently complicated by neurological complications and coagulopathy. However, the relationship between the coagulation system and neurological complications in patients with acute aortic dissection has not been clarified. Thus, the aim of this study was to investigate the relationship between the coagulation system and neurological complications in patients with acute aortic dissection.From September 2014 to January 2016, a total of 126 patients with acute type A aortic dissection were enrolled. Perioperative characteristics and standard laboratory tests upon admission were analyzed using univariate and multivariate logistic regression analysis in this study. The primary outcome was the correlation between the coagulation system and neurological complications.Univariate logistic regression analysis showed that the neurological complications (+) group underwent more serious and complicated postoperative outcomes. Multivariable logistic regression analysis revealed serum creatinine level (OR, 1.049; 95% CI, 1.011-1.089; P = .01), white blood cell counts (OR, 1.581; 95% CI, 1.216-2.057; P = .001) and fibrinogen concentration upon admission (OR, 0.189; 95% CI, 0.060-0.596; P = .004) as predictors of neurological complications. However, we found that there was no association between the coagulation system and in-hospital mortality.Low preoperative fibrinogen level is the preferred marker for predicting clinical neurological complications in patients with acute type A aortic dissection treated with surgical repair.

Abstract
INTRODUCTION Body temperature maintained during open distal anastomosis in patients who undergo aortic surgery has been showing an upward trend; however, a higher temperature may increase visceral organ and spinal cord injury. Distal perfusion may reduce abdominal organ injury, especially acute kidney injury (AKI). METHODS From 2009 to 2016, 56 patients who underwent ascending aortic and/or aortic arch surgery were enrolled. Open distal anastomosis was performed using one of three protection strategies: 1) systemic temperature of 25°C followed by selective cerebral perfusion (SCP) with lower body circulatory arrest (Group CA25, n=27); 2) systemic temperature of 28°C followed by SCP with lower body circulatory arrest (Group CA28, n=4); and 3) systemic temperature of 28°C followed by SCP with distal aortic perfusion (Group DP, n=25). RESULTS During the postoperative course, levels of blood urea nitrogen, creatinine, liver enzymes, lactate dehydrogenase and lactate in Groups CA28 and CA25 were significantly higher than those in Group DP. AKI defined by the AKI Network occurred in 28 cases (50%) and 3 cases required permanent hemodialysis. AKI was significantly higher in Groups CA25 and CA28 than in Group DP (p=0.026). Mid-term follow-up showed that patients who developed postoperative AKI were more likely to suffer from cardiovascular events. CONCLUSIONS Distal perfusion during open distal anastomosis reduced kidney and liver injury after thoracic aortic surgery despite an increased body temperature of up to 28°C. This strategy may be useful to prevent AKI, liver dysfunction, the need for hemodialysis and multiple organ failure and could improve mid-term results.

Abstract
OBJECTIVES Organ protective management during aortic arch surgery comprises deep hypothermic (18°C) circulatory arrest (DHCA), or moderate hypothermia (28°C/ 'tepid') with regional cerebral perfusion (TRCP). The aim of this experimental study was to evaluate the effect of distinct organ protective management on hemodynamic performance and myocardial integrity. METHODS Ten male piglets were randomized to group DHCA (n = 5) or TRCP (n = 5) group and operated on cardiopulmonary bypass (CPB) with 60 min of aortic cross-clamping. Blood gas analysis was performed throughout the experiment. Haemodynamic assessment was performed using a thermodilution technique before and after CPB. Myocardial biopsies were taken 2 h after CPB and evaluated using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labelling assay and western blot analysis. RESULTS At reperfusion, levels of central venous saturation were significantly higher (P = 0.016) and levels of lactate significantly lower (P = 0.029) in the DHCA group. After CPB, thermodilution measurements revealed higher stroke volume and lower peripheral resistance in the TRCP group (P = 0.012 and 0.037). At the end of the experiment, no significant differences regarding laboratory and haemodynamic parameters were evident. All specimens showed enrichment of terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labelling-positive cells exclusively at the left ventricular subendocardium with no difference between groups and equal concentrations of cyclo-oxygenase-2. CONCLUSIONS TRCP is associated with decreased peripheral resistance and higher stroke volume immediately after CPB. However, this beneficial effect is contrasted by signs of lower body hypoperfusion, which is expressed by lower central venous saturations and higher lactate levels. Distinct strategies of organ protection did not seem to affect apoptotic/necrotic and inflammatory changes in the left ventricular myocardium.

Abstract
Objectives Improved congenital heart defect (CHD) operations have reduced operative mortality to 3%. The major concern is now long-term neurological outcomes. We measured plasma glial fibrillary acidic protein (GFAP), an early marker of brain injury, during different phases of cardiopulmonary bypass (CPB), to correlate the increase of GFAP to clinical parameters or specific operative phases. Methods We performed a prospective, single-centre, observational study in children undergoing cardiac operations. We studied 69 children with CHD and biventricular heart physiology: 26 had tetralogy of Fallot; 17 transposition of the great arteries; and 26 ventricular/atrial septal defects with or without associated arch defects. GFAP levels were measured by ELISA at different stages of CPB. We recorded clinical and surgical parameters and applied multivariable and logistic regressions to assess which parameters were independent predictors of variations in plasma GFAP. Results GFAP increased during CPB and peaked at the end of rewarming. Multivariable regression showed degree of hypothermia as the only significant independent predictor of GFAP increase, adjusted for age, prematurity, type of CHD, cyanosis, aortic cross-clamp time, haemodilution, neurological risk time interval and rewarming rate. Temperature nadir and neurological risk time interval were significant independent predictors of a GFAP value > 0.46 ng/ml. Conclusions Hypothermia degree during CPB is correlated with GFAP plasma increase in children with biventricular heart defects undergoing surgical repair. Rewarming is the most critical CPB phase for GFAP increase. The implication of high plasma GFAP is still under evaluation. Follow-up studies are ongoing to assess the reliability of GFAP as a marker of brain injury and/or as a predictor of neurodevelopmental abnormalities.

Abstract
BACKGROUND Neurological dysfunction may occur after corrective cardiac surgery using cardio-pulmonary bypass (CPB) with or without circulatory arrest. Different neurophysiological monitoring systems have been employed to detect neurological complications and possible brain injury in infants and children during and after cardiac surgery. The value of Elecetroencephalogram (EEG) in infants and children at risk for neurological sequelae has not been systematically studied. METHODS Sequential performance of two EEGs before and after cardiac surgery at a tertiary University Hospital to screen for possible brain injury after cardiac surgery in neonates and children undergoing CPB surgery. In addition, a complete neurological examination and assessment by a physiotherapist was performed. RESULTS Over a 4-year period, in 313 patients (age: 54.2 ± 55.7 months; normal initial EEG) after cardiac surgery CPB (duration of surgery: 146.0 ± 58.9 min; aortic cross clamp time: 34.1 ± 19.1 min), a 19-channel EEG recording was performed 2.4 ± 1.8 days prior to and 11.6 ± 5.3 days after cardiac surgery. An abnormal EEG was detected in only 8 of 313 patients (2.5%; focal slowing: 1, generalised slowing: 5, epiletiform discharges: 2) after cardiac surgery, while the EEG was normal in the remaining 305 patients (97.5%). In 1 patient, an intra-cerebral pathology was seen on MRI (ischemic); in 5 patients, follow-up EEGs were performed, which revealed normalized findings. None of the 8 patients demonstrated new focal neurological deficits on physical examination, but 33 (9.7%) children demonstrated minor abnormalities (e.g., subtle motor asymmetry, increase in muscle tone, etc.), which were unrelated to abnormal EEG findings. CONCLUSIONS According to the used protocol, pathological EEG findings were very infrequent in our study cohort. The routine and indiscriminative recording of EEGs in children before and after corrective or palliative cardiac surgery for congenital heart disease using CPB is not recommended. Further intra-operative neuromonitoring methods with immediate intervention should be evaluated.

Abstract
OBJECTIVE The optimal strategy to deliver antegrade cerebral perfusion for cerebral protection during hypothermic circulatory arrest has not been established. The purpose of this review was to present our current clinical protocol utilizing selective antegrade cerebral perfusion during aortic arch surgery and to compare it to other published experience. CLINICAL PROTOCOL Since 2013, our clinical protocol for aortic arch surgery has evolved to using selective antegrade cerebral perfusion via the innominate artery, moderate hypothermia, and ancillary strategies such as goal-directed perfusion (GDP). Other published techniques favored antegrade cerebral perfusion but were limited by smaller cannulae, multiple cannulation sites, and lower cooling temperatures. CONCLUSION Our clinical protocol may offer higher flow rates, avoid complications associated with additional cannulae, and provide an easy setup for dual arterial perfusion. Additionally, GDP has enhanced our understanding of metabolic physiology and may facilitate the development of a better cerebral protection strategy.

Abstract
Coagulopathy is still a frequent complication in the surgical treatment of acute aortic dissection. However, the physiopathology of surgically induced coagulopathy has never been systematically and comprehensively studied in patients with acute aortic dissection. The aim of the present study was to describe the perioperative hemostatic system in patients with acute aortic dissection.The 87 patients who underwent aortic arch surgery for acute Stanford type A aortic dissection from January 2013 to September 2015 were enrolled in this study. The perioperative biomarkers of hemostatic system were evaluated using standard laboratory tests and enzyme-linked immunosorbent assays (ELISAs) at 5 time points: anesthesia induction (T1), lowest nasopharyngeal temperature (T2), protamine reversal (T3), 4 hours after surgery (T4), and 24 hours after surgery (T5).The ELISAs biomarkers revealed activation of coagulation (thrombin-antithrombin III complex [TAT] and prothrombin fragment 1 + 2 [F1 + 2] were elevated), suppression of anticoagulation (antithrombin III [AT III] levels were depressed), and activation of fibrinolysis (plasminogen was decreased and plasmin-antiplasmin complex [PAP] was elevated). The standard laboratory tests also demonstrated that surgery resulted in a significant reduction in platelet counts and fibrinogen concentration.Systemic activation of coagulation and fibrinolysis, and inhibition of anticoagulation were observed during the perioperative period in patients with acute aortic dissection. Indeed, these patients exhibited consumption coagulopathy and procoagulant state perioperatively. Therefore, we believe that this remarkable disseminated intravascular coagulation (DIC)-like coagulopathy has a high risk of bleeding and may influence postoperative outcome of patients with acute aortic dissection.

Abstract
Brain protection during cardiopulmonary bypass has been the subject of intense research. Deep hypothermic circulatory arrest (DHCA) continues to be used for that goal during complex aortic arch and large intracranial aneurysm surgeries. The anesthetic management for adult patients undergoing these types of procedures requires specific knowledge and expertise. Based on our experience and review of the current literature, the authors highlight the key areas of the anesthetic plan, discussing the risk factors associated with adverse neurologic outcome as well as the rationale for decisions regarding specific monitors and medications. In the conclusion an anesthetic protocol for adult patients undergoing DHCA is suggested.

Abstract
Hypothermic circulatory arrest is a critical component of aortic arch procedures, without which these operations could not be safely performed. Despite the use of hypothermia as a protective adjunct for organ preservation, aortic arch surgery remains complex and is associated with numerous complications despite years of surgical advancement. Deep hypothermic circulatory arrest affords the surgeon a safe period of time to perform the arch reconstruction, but this interruption of perfusion comes at a high clinical cost: stroke, paraplegia, and organ dysfunction are all potential-associated complications. Retrograde cerebral perfusion was subsequently developed as a technique to improve upon the rates of neurologic dysfunction, but was done with only modest success. Selective antegrade cerebral perfusion, on the other hand, has consistently been shown to be an effective form of cerebral protection over deep hypothermia alone, even during extended periods of circulatory arrest. A primary disadvantage of using deep hypothermic circulatory arrest is the prolonged bypass times required for cooling and rewarming which adds significantly to the morbidity associated with these procedures, especially coagulopathic bleeding and organ dysfunction. In an effort to mitigate this problem, the degree of hypothermia at the time of the initial circulatory arrest has more recently been reduced in multiple centers across the globe. This technique of moderate hypothermic circulatory arrest in combination with adjunctive brain perfusion techniques has been shown to be safe when performing aortic arch operations. In this review, we will discuss the evolution of these protection strategies as well as their relative strengths and weaknesses.

Abstract
OBJECTIVES To determine whether, in patients with previous cardiac operations, moderate hypothermia (between 24 and 28°C) for hypothermic circulatory arrest (HCA) during antegrade cerebral perfusion (ACP) is safe for use during surgery on the proximal aorta and transverse aortic arch. METHODS Over a 7-year period, 118 patients underwent ascending aortic and hemiarch repair (n = 70; 59.3%), total arch replacement (n = 47; 39.8%) or ascending aortic replacement to treat porcelain aorta (n = 1; 0.9%). Simultaneous procedures included aortic root repair or replacement (n = 33; 28.0%) and coronary artery bypass grafting (n = 21; 17.8%). All patients had previously undergone cardiac operations via a median sternotomy. Eighteen patients (15.3%) had more than 1 previous sternotomy, and 24 patients (20.3%) required emergent/urgent operation. Median cardiopulmonary bypass, cardiac ischaemic, circulatory arrest and ACP times (min) were 136.0 [118-180 interquartile range (IQR)], 91.0 (68-119 IQR), 34.0 (21-59 IQR) and 33.5 (20-59 IQR), respectively. The median temperature when HCA was initiated was 24.2°C (24.1-24.8°C IQR). RESULTS The operative mortality rate was 10.2% (n = 12). Six patients (5.1%) had a permanent stroke, and 16 patients (13.6%) had a composite adverse outcome (operative mortality and/or a permanent neurological event and/or permanent haemodialysis at discharge). Preoperative renal disease was significantly more prevalent (P= 0.020) and the median circulatory arrest time significantly longer (48.5 vs 33 min; P= 0.058) in patients with composite adverse outcomes. Multivariable analysis of the redo patients showed that age (P =0.025), preoperative renal disease (P =0.024) and ACP time (P =0.012) were independent risk factors for a new postoperative renal injury. CONCLUSIONS Moderate hypothermia for HCA during ACP is being used with increasing frequency, but has not been thoroughly evaluated in patients undergoing cardiovascular reoperations. Our experience suggests that in patients with previous cardiac surgery who are undergoing hemiarch and total aortic arch operations, moderate hypothermia is safe and produces respectable results.

Abstract
BACKGROUND Continued debates exist regarding the optimal temperature during hypothermic circulatory arrest (HCA) in aortic arch repair for patients with type A aortic dissection (TAAD). This study seeks to examine whether the use of moderate HCA in emergency aortic arch surgery provides comparable operative outcomes to deep HCA for patients with acute TAAD. METHODS We prospectively enrolled 74 consecutive patients (mean age 47.7±9.8 years, 54 males) with acute TAAD, who underwent emergency total arch replacement and frozen elephant trunk implantation under HCA (18-28 °C) with unilateral selective antegrade cerebral perfusion (uSACP). Patients were divided into two groups based on the nasopharyngeal temperature at the initiation of HCA: deep HCA (DHCA, <20 °C) in 35 (47.3%) and moderate HCA (MHCA, 20-28 °C) in 39 (52.7%). Operative outcomes including mortality, morbidity and visceral organ functions were compared between the two groups. RESULTS The mean times of cardiopulmonary bypass (CPB) and aortic cross-clamp were 211±54 and 238±62 minutes (P=0.053) and 118±27 and 142±45 minutes (P=0.005) in the MHCA and DHCA groups, respectively. Operative mortality did not differ between two groups (10.2% in MHCA vs. 14.3% in DHCA groups, P=0.862). Nor did the incidence of morbidities differ between the two groups (P>0.05). The temporal trend in the changes of postoperative levels of creatinine, aspartate aminotransferase, total bilirubin and lactate did not differ between two groups (P>0.05). Multivariate analysis found that the temperature during HCA (MHCA vs. DHCA) did not affect operative mortality, morbidities and neurologic complications. Instead, CPB time (in minutes) was the risk factor for operative mortality (odds ratio, 1.032; 95% confidence interval, 1.004-1.061; P=0.023). CONCLUSIONS Moderate HCA is associated with equivalent operative mortality and morbidity and visceral organ functions compared to deep HCA in patients with acute TAAD undergoing total arch replacement under uSACP. This study implies the clinical safety and efficacy of moderate HCA in emergency aortic arch repair for such patients, which provides equivalent cerebral and visceral organ protection while decreasing CPB and cross-clamp times without increasing the risk of operative mortality and morbidity.
