Background: “Type A” acute aortic dissection (AAAD) is the most challenging among the emergency operations in cardiac surgery. The aim of this study was the evaluation of the role of acute renal failure (ARF) in postoperative survival of patients operated for AAAD. Methods: From February 2010 to April 2012, 37 consecutive patients were operated at our department for AAAD. We studied our population by subdividing the patients within groups according to the presence of ARF requiring continuous veno-venous hemofiltration (CVVH) and according to hypothermic circulatory arrest (HCA) times and degrees. Results: The overall 30-day mortality was 27% (50% group A with ARF, 13% group B no ARF). Acute renal failure requiring CVVH was 37.8%. Multivariate analysis revealed a significant association with 30-day mortality (odds ratio 6.6 and p = 0.020). Preoperative oliguria [urine output less than 30 ml/h (odds ratio 4.7 p = 0.039)], CPB greater than 180 minutes (odds ratio 6.5 p = 0.023) and postoperative bleeding requiring a surgical reopening (odds ratio 12.2 and p = 0.021) were the variables significantly associated with acute kidney injury. Conclusions: The data obtained from our analysis bring out the high incidence of renal injuries after surgery for AAAD, and indicate a negative impact on renal injuries of a preoperative oliguria, longer Cardiopulmonary bypass (CBP)/HCA times, and postoperative bleeding requiring a surgical revision. Our data also suggest a better 30-day survival and better renal outcomes in case of shorter HCA and lesser degree of hypothermia. The option of lesser and shorter hypothermia may be very useful, especially for the elderly patients and octogenarians.

The purpose of this case presentation is to present a simplified surgical technique when in a patient with acute aortic dissection type A (AAD), aortic arch, and ascending aorta is completely replaced without circulatory arrest. A 67-year old male was presented in our institution with severe chest and back pain at 12 h after the onset of the symptoms. Imaging studies by 3D contrast-enhanced thoracic computed tomography (CT-scan) and transesophageal echocardiography (TEE) revealed ascending aortic dissection towards the aortic arch, which was extending in the proximal descending aorta. We practiced emergency median sternotomy and established cardiopulmonary bypass (CBP) between the right atrium and the right femoral artery with successive cross-clamping of the ascending and descending aorta below the origin of the left subclavian artery (LSA). In normothermic condition without circulatory arrest and with antegrade cerebral perfusion, we replaced the ascending aorta and aortic arch with a four branched Dacron graft. Patient evolution was uneventful, and he was discharged, after fourteen days from the hospital. At a one-year follow-up, 3D CT-scan showed no residual dissection with a well-circulated lumen of the supra-aortic arteries. Using the described surgical approach, CPB was not interrupted, the brain was protected, and hypothermia was no used. This approach made these surgical procedures shorter, and known complications of hypothermia and circulatory arrest are avoided.Acute aortic dissection aortic type A, total arch replacement, normothermia

Abstract The surgical management for type A acute aortic dissection complicated with carotid artery occlusion remains controversial. Between December 2012 and June 2017, 127 patients who presented with type A acute aortic dissection were operated on in our hospital. Of this group, nine (7.08%) patients had cerebral malperfusion due to carotid artery occlusion. The site of occlusion was innominate artery (n = 5) or right carotid artery (n = 4). Preoperative neurological symptoms were left hemiplegia (n = 1), left hemiparesis (n = 3) and seizure (n = 2). Preoperative consciousness level was Japan Coma Scale 2 (n = 6), 20 (n = 2), or 200 (n = 1). The procedure consisted of hemiarch replacement (n = 4) or total arch replacement (n = 5). Aorto-carotid bypass was performed in all patients under hypothermic circulatory arrest. The time from onset of symptoms to operating room was 7.2 ± 2.4 h. Hospital mortality was 0%. Left hemiplegia and left hemiparesis improved significantly. Japan Coma Scale was 0 in all patients at discharge. Overall survival at 24 months after operation was 100%. Aorto-carotid artery bypass for type A acute aortic dissection with carotid artery occlusion is the treatment of choice in these high-risk patients. Our strategy of ‘no touch until circulatory arrest’ may contribute to neurological improvement.

Introduction: Recent reports of retrograde acute type A aortic dissection (RTAAD) following thoracic aortic endovascular repair have been associated with poor outcomes. This raises concerns about outcomes with RTAAD in general. We report and compare outcomes of retrograde acute Type A aortic dissection repair with classic acute aortic dissection (CAAD). Methods: Between 8/1991 and 5/2008, we repaired 322 patients with acute type A dissection. This cohort was divided into two groups: RTAAD Group (52 cases), and CAAD Group (270 cases). RTAAD was defined as the presence of a dissection tear originating distal to the arch as identified intra-operatively. Tears in the ascending aorta denoted dissection as classic. Repairs using circulatory arrest were similar between groups, p>0.33. Preoperative, operative, and post-operative variables were analyzed retrospectively. Results: Retrograde type A aortic dissection occurred in 16.1% (52/322) of patients. RTAAD differed from CAAD in the median time from initial symptoms to operation (75+−87 hours vs. 47+−61 hours) and specific presenting conditions. (See Table 1 ) Outcomes (stroke: RTAAD, 2.1% vs. CAAD, 3.6%, bleeding: 4% vs. 9%, myocardial infarction: 6% vs. 6%, and mortality: 11% vs. 18%) did not differ significantly between the groups, p>0.05. Conclusions: RTAAD presented later for repair and less frequently with redo-sternotomy and aortic valvular insufficiency. Despite these differences, outcomes from surgical repair did not differ significantly. Acceptable outcomes may be achieved with timely intervention. Table 1: Preoperative Variables

Abstract Introduction Acute aortic dissection Type A (AADA) is still associated with a high mortality rate and frequent postoperative complications. This study was designed to evaluate the risk factors for mortality in AADA patients. Patients and Methods This retrospective analysis included 344 consecutive patients who underwent surgery for AADA in moderate hypothermic circulatory arrest (20–24°C nasopharyngeal) between 2001 and 2016. Results The 30-day mortality rate was 18%. Nonsurvivors were significantly older (65.7 ± 12.0 years vs. 62.0 ± 12.5 years; p = 0.034) with significantly higher Euro-score II [15.4% (6.6; 23.0) vs. 4.63% (2.78; 9.88); p < 0.001)]. Intraoperatively, survivors had statistically shorter cardiopulmonary bypass times [163 (134; 206) vs. 198 min (150; 245); p = 0.001]. However, the hypothermic circulatory arrest time was similar between both groups. Postoperatively, the incidence of acute kidney injury (AKI) (55.9 vs. 15.2%; p < 0.001), stroke (27.9 vs. 12.1%; p = 0.002) and sepsis (18.0 vs. 2.1%; p < 0.001) were significantly higher among nonsurvivors. The multi-variable logistic regression confirmed that older age, previous cardiac surgery, preoperative cardiopulmonary resuscitation (CPR), blood transfusion and postoperative acute kidney injury (AKI) were independent risk factors for mortality. Conclusion Our analysis suggested that the reason for mortality was multifactorial, especially age, previous cardiac surgery, CPR, transfusion, as well as postoperative AKI were considered risk factors for mortality.

Objectives: The site of cannulation for repair of ascending aortic dissection remains controversial. Here we present our experience with ascending aortic cannulation for acute aortic dissection type A (AADA). Methods: From 01/1988 to 09/2007, we operated on 242 patients for AADA. Medical records of 235 patients who received ascending aortic cannulation or femoral cannulation were retrospectively reviewed. Long term follow-up was complete in 97% of patients. Cannulation was accomplished in 82 patients through the ascending aorta and in 153 patients through the femoral artery. Results: There were no significant differences in preoperative characteristics between groups. Similarly, there were no differences in preoperative patient characteristics and intraoperative parameters including operation time (ascending 357±139 vs. peripheral 342±125 min.; p=0.40), bypass time (ascending 219±105 vs peripheral 206±96 min.; p=0.32), cross-clamp time (ascending 106±43 vs peripheral 106±51 min.; p=0.69), hypothermic circulatory arrest time (ascending 28±19 vs peripheral 27±23 min.; p=0.73), and percentage of total arch replacement (ascending 54.9% vs peripheral 55.7%; p=0.44). Hospital mortality was 12.2% in each group (p=0.98), and incidence of stroke was 4.9% in ascending group and 4.5% in peripheral group (p=0.86). During follow-up (mean 5.5 years), survival at 5 years and 10 years was 65% and 41% in ascending group and 64% and 46% in peripheral group, respectively (p=0.97). No persistent malperfusion by ECC was observed after aortic cannulation. Conclusions: Direct cannulation of the dissected aorta in patients with AADA was safe with acceptable results in our study cohort. The conventional femoral cannulation had no advantage on the direct cannulation strategy, and the avoidance of additional incision and possible peripheral vascular injury may favor the direct cannulation strategy.
