Abstract Background: Hyperuricemia is associated with aortic dissection and cardiovascular diseases. The implication of high serum uric acid (UA) level after acute aortic dissection repair remains unknown. The aim of this study is to explore the role of peri-operative serum UA level in predicting 30-days mortality with acute type A aortic dissection (AAAD) patients, who underwent surgery. Methods and Results: 209 consecutive AAAD patients were included, 14.3% (n=30) were dead within 30 days after surgery. By univariate analysis, we found AAAD repair patients with 30-days mortality had a higher prevalence of cerebral malperfusion, lower pre-operative fibrinogen, longer cardiopulmonary bypass and aortic crossclamp time, and higher post-operative day 1 (POD1) creatinine and urea levels. Both pre-operative (433.80±152.59 vs. 373.46±108.31mmol/L, P=0.038) and POD1 (559.78±162.23 vs. 391.29±145.19 mmol/L, P=0.000) UA level were higher in mortality group than in survival group. In regression model, only cerebral malperfusion (OR, 7.937, 95% CI, 1.252-50.323; P=0.028) and POD1 UA level (OR, 1.006; 95% CI, 1.003-1.009; P=0.000) were independent predictors of 30-days mortality in AAAD repair patients. According to the ROC curve, the POD1 UA level provided positive value for 30-days mortality in AAAD repair patients with 0.799 areas under the curve. The optimum cutoff value selected by ROC curve was 500.15 mmol/L, with a sensitivity of 69.2% and a specificity of 81.7%. Conclusion: Pre- and post-operative hyperuricemia are potentially associated with worsened outcomes in AAAD surgery patients. The POD1 UA level has a predictive role in 30-days mortality in AAAD repair patients.

The Impact

Acute type A aortic dissection is a surgical emergency and management of such pathology can be complex with poor outcomes when there is organ malperfusion. Carotid artery involvement is present in 30% of patients diagnosed with acute type A aortic dissection, and given its emergency and complex nature, there is much controversy regarding the approach, extent of treatment, and timing of the intervention. It is clear that the occurrence of cerebral malperfusion adds an extra layer of complexity to the decision-making framework for treatment. Standardization and validation of the optimal management approach is required, and this should ideally be addressed with large-scale studies. Nonetheless, current literature supports the need for rapid recognition and diagnosis of acute type A aortic dissection with cerebral malperfusion, immediate and extensive surgical repair, and the appropriate use of cerebral perfusion techniques. This paper aims to discuss the current evidence regarding the impact of carotid artery involvement in both the management and outcomes of acute type A aortic dissection.

Background Total arch replacement with modified elephant trunk technique plays an important role in treating acute type A aortic dissection in China. We aim to summarize the therapeutic effects of this procedure in our center over a 17-year period. Methods Consecutive patients treated at our hospital due to type A aortic dissection from January 2004 to January 2021 were studied. Relevant data of these patients undergoing total arch replacement with modified elephant trunk technique were collected and analyzed. Results A total of 589 patients were included with a mean age of 53.1 ± 12.2 years. The mean of cardiopulmonary bypass, cross-clamping, and selected cerebral perfusion time were 199.6 ± 41.9, 119.0 ± 27.2, and 25.1 ± 5.0 min, respectively. In-hospital death occurred in 46 patients. Multivariate analysis identified four significant risk factors for in-hospital mortality: preexisting renal hypoperfusion (OR 5.43; 95% CI 1.31 – 22.44; P = 0.020), cerebral malperfusion (OR 11.87; 95% CI 4.13 – 34.12; P < 0.001), visceral malperfusion (OR 4.27; 95% CI 1.01 – 18.14; P = 0.049), and cross-clamp time ≥ 130 min (OR 3.26; 95% CI 1.72 – 6.19; P < 0.001). The 5, 10, and 15 years survival rates were 86.4%, 82.6%, and 70.2%, respectively. Conclusions Total arch replacement with modified elephant trunk technique is an effective treatment for acute type A aortic dissection with satisfactory perioperative results. Patients with preexisting renal hypoperfusion, cerebral malperfusion, visceral malperfusion, and long cross-clamp time are at a higher risk of in-hospital death.

Abstract OBJECTIVES Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS The Nordic Consortium for Acute Type A Aortic Dissection database included patients operated for ATAAD at 8 Scandinavian Hospitals between 2005 and 2014. RESULTS Stroke occurred in 177 (15.7%) out of 1128 patients. Patients with stroke presented more frequently with cerebral malperfusion (20.6% vs 6.3%, P &lt; 0.001), syncope (30.6% vs 17.6%, P &lt; 0.001), cardiogenic shock (33.1% vs 20.7%, P &lt; 0.001) and pericardial tamponade (25.9% vs 14.7%, P &lt; 0.001) and more often underwent total aortic arch replacement (10.7% vs 4.7%, P = 0.016), compared to patients without stroke. In the 86 patients presenting with cerebral malperfusion, 38.4% developed stroke. Thirty-day and 5-year mortality in patients with and without stroke were 27.1% vs 13.6% and 42.9% vs 25.6%, respectively. Stroke was an independent predictor of early- [odds ratio 2.02, 95% confidence interval (CI) 1.34–3.05; P &lt; 0.001] and midterm mortality (hazard ratio 1.68, 95% CI 1.27–2.23; P &lt; 0.001). CONCLUSIONS Stroke in ATAAD patients is associated with increased early- and midterm mortality. Preoperative cerebral malperfusion and impaired haemodynamics, as well as total aortic arch replacement, were more frequent among patients who developed stroke. Importantly, a large proportion of patients presenting with cerebral malperfusion did not develop a permanent stroke, indicating that signs of cerebral malperfusion should not be considered a contraindication for surgery.

Hemiarch Replacement

Background Aortic enlargement after hemiarch replacement (HAR) for acute type A aortic dissection (AAAD) is a serious problem. We reviewed our experience and analyzed the risk factors for aortic enlargement. Methods During April 2005 to December 2017, 364 patients underwent HAR for AAAD. Seventy-three patients fulfilled the inclusion criteria. We analyzed the change in aortic diameter, aortic growth rate, and major adverse aortic events (MAAEs) and their association with luminal communication of the aortic arch. Results Anastomotic communication, supra-aortic communication (SAC), and distal aortic communication were found in 34 (46.6%), 28 (38.4%), and 20 (27.4%) patients, respectively. The aortic growth rate was high because of the presence of SAC, distal aortic communication, and the number of coexisting aortic communication. Univariate analysis showed that the presence of SAC and an initial aortic diameter > 35 mm at 20 mm distal to the left subclavian artery and at the pulmonary artery bifurcation (PAB) were risk factors for MAAEs. Multivariate analysis showed that SAC and an initial aortic diameter > 35 mm at the PAB were independent risk factors for MAAEs. Conclusion SAC, distal aortic communication, and the number of coexisting aortic communication are significant risk factors for aortic enlargement after HAR for AAAD. SAC and an initial aortic diameter > 35 mm at the PAB are independent risk factors for MAAEs after this procedure.

Abstract OBJECTIVES We aimed to identify predictors of postoperative permanent neurological deficits (PNDs) and evaluate the early management of cerebral perfusion in patients undergoing surgical repair of acute type A aortic dissection with cerebral malperfusion. METHODS Between October 2009 and September 2018, a total of 197 patients with acute type A aortic dissection underwent aortic replacement. Of these, 42 (21.3%) patients had an imaging cerebral malperfusion (ICM). ICM was assessed preoperatively, which also revealed whether dissected supra-aortic branch vessels were occluded or narrowed by a thrombosed false lumen. After September 2017, early reperfusion and extra-anatomic revascularization were performed in cases with ICM. RESULTS Hospital mortality rates for cases with ICM were 4.8% (2/42). Before September 2017, PND were observed in 6 patients (54.5%) with preoperative neurological symptoms (n = 11), and 7 patients (33.3%) without neurological symptoms (n = 21) in patients with ICM. Occlusion or severe stenosis of supra-aortic branch vessels (odds ratio, 7.66; P &lt; 0.001), regardless of preoperative clinical neurological symptoms, was a risk factor for PND. After September 2017, 7 of 10 patients with ICM underwent early reperfusion and extra-anatomic revascularization. PND did not occur in any of these 7 patients. CONCLUSIONS Occlusion or severe stenosis of supra-aortic branch vessels is a predictor of PND risk in patients undergoing surgery for acute type A aortic dissection. Early reperfusion and extra-anatomic revascularization may reduce the risk of neurological complications in patients with ICM, with or without neurological symptoms.

During treatment of acute type A aortic dissection there is potential for both pre- and intra-operative malperfusion. There are a number of monitoring strategies that may allow for earlier detection of potentially catastrophic malperfusion (particularly cerebral malperfusion) phenomena available for the anaesthetist and surgeon. This review article sets out to discuss the benefits of the current standard monitoring techniques available as well as desirable/experimental techniques which may serve as adjuncts in the monitoring of these complex patients.
