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.

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.

Abstract OBJECTIVES Our aim was to evaluate clinical and neurological effects of common carotid artery (CCA) true lumen flow impairment or occlusion in patients with type A aortic dissection. METHODS Characteristics and imaging data of patients with dissected CCA secondary to acute type A aortic dissection from 3 institutions were analysed. We defined true lumen blood flow as unimpaired when the maximum true lumen diameter exceeded 50% of the complete CCA diameter, as impaired when the true lumen was compressed to ˃50% of the complete lumen, or as occluded. RESULTS Out of 440 patients, 207 presented unimpaired CCA flow, 172 impaired CCA flow and CCA occlusion was present in 61 patients. Preoperative shock (P = 0.045) or a neurological deficit (P &lt; 0.001) were least common in patients with unimpaired CCA flow and most common in those with CCA occlusion. Non-cerebral, other-organ malperfusion was common in 37% of all patients, but the incidence was similar (P = 0.69). In patients with CCA occlusion, postoperative stroke (P &lt; 0.001) and in-hospital mortality (0.011) were significantly higher, while the incidences were similar between patients with unimpaired and impaired CCA flow. Mixed-effects logistic regression models showed that CCA flow impairment (P = 0.23) or occlusion (P = 0.55) was not predictive for in-hospital mortality, but CCA occlusion was predictive for in-hospital stroke (odds ratio 2.166, P = 0.023) CONCLUSIONS Shock and non-cerebral, other-organ malperfusion are common in patients with CCA dissection. While there is a high risk for stroke in patients with CCA occlusion, CCA flow impairment and occlusion were not predictive for in-hospital mortality. Surgery should not be denied to patients with CCA flow impairment or occlusion.

The Impact

Introduction: Acute type A aortic dissection (ATAAD) is rapidly lethal and requires comprehensive tactics and decision making. To refine our respective approach we retrospectively analyzed our patients undergoing urgent surgery in our hybrid operating room over a 10 year period for the impact of immediate preoperative coronary angiography (CA), aortography, and/or intravascular ultrasound (IVUS) for the detection of coronary artery disease (CAD) and/or arterial malperfusion. Methods: 136 patients (mean age: 60.6 y ± 13; 63% male, March 2004-February 2014) underwent preoperative CA with or without IVUS. We assessed the time interval from preoperative CA to surgery and the impact for concomitant coronary artery bypass grafting (CABG) or endovascular interventions. Results: The delay to proceed with surgery due to preoperative catheterization averaged 32 min ± 26 (Fig. 1) in the setting of the hybrid OR. CA revealed CAD in 47/136 (35%) patients, with CABG consequently performed in 38 (28%). In 12 (9%) patients, CABG was necessary due to ostium obstruction by the dissection. 30-day mortality more than doubled in patients with concomitant CAD (27.7% vs. 11.2%, respectively, p<0.01). However in patients with confirmed CAD, mortality was less 19% (6/31), in those undergoing CABG, compared to 44% (7/16) for isolated aortic repair (p=0.08). Conclusions: In a hybrid operating room setting, preoperative coronary and aortic angiography do not unduly delay surgery, facilitate diagnosis of coronary malperfusion, and allowing concomitant CABG in as much as 28% of patients.
