Early and late outcomes of type A acute aortic dissection with common carotid artery involvement.

ABSTRACT:

Objective

The relationship between common carotid artery (CCA) involvement in acute type A aortic dissection (ATAAD) and postoperative outcomes remains unclear. We investigated outcomes and described our current advanced strategy.

Methods

Of 492 patients who underwent surgical repair for ATAAD between September 1999 and February 2021, CCA involvement was identified in 114. Eighty of these 114 patients (70.2%) were classified as having a thrombosed CCA and 34 (29.8%) were classified as nonthrombosed. To prevent postoperative cerebral malperfusion, we initiated a strategy of early reperfusion and direct reconstruction of dissected and thrombosed CCAs regardless of neurologic symptoms.

Results

Fifty-five patients (48.2%) showed preoperative neurologic symptoms. No significant differences between the thrombosed and nonthrombosed groups were seen in postoperative mortality (20.0% vs 11.8%; P = .421) or frequency of postoperative modified Rankin scale (mRS) score ≥5 (30.0% vs 17.6%; P = .245). The rate of postoperative neurologic deficit was significantly higher (48.8% vs 23.5%; P = .013) and long-term survival rate was significantly lower (5 years; 59.1 ± 6.3% vs 77.9 ± 7.4%; 10 years: 50.0 ± 7.9% vs 72.3 ± 8.7%; P = .041) in the thrombosed group. Risk factors for mRS ≥5 from multivariable analysis included occluded thrombosed CCA, preoperative coma, preoperative shock, and prolonged operation time. Fifteen patients were treated with the early reperfusion and direct reconstruction strategy; postoperative mortality 13.3% (2 patients). No patients showed cerebral reperfusion syndrome.

Conclusions

In patients with CCA involvement, a thrombosed false lumen, especially an occluded CCA, resulted in worse outcomes regardless of preoperative neurologic symptoms. Further study is needed to evaluate the efficacy of the current strategy.

Project description:BackgroundOptimal management of involved common carotid artery (CCA) with false-lumen thrombus remains unclear in aortic dissection patients. We aim to investigate outcomes and compare different surgical strategies.MethodsThis is a retrospective cohort study and the institutional database of acute type A aortic dissection was reviewed. The patients with CCA involvement and extended false-lumen thrombus were enrolled and grouped according to the management of CCA: extra-thoracic carotid artery replacement (CAR) and reconstruction in situ (RIS). Multivariate logistic regression analysis was used to investigate the effect of management on neurological outcomes. Kaplan-Meier method was used for survival analysis and log-rank test was used to compare the difference on survival rate.ResultsFrom March 2011 to December 2019, 68 patients were enrolled (24 in the CAR group and 44 in the RIS group). The overall operative mortality was 7.4% (5 patients) and 21 patients had the incidence of postoperative neurological deficit was (30.9%). The rates of main postoperative complications were similar between the two groups. Twenty-five (56.8%) patients in the RIS group had residual false-lumen thrombus at discharge. In multivariate analysis, CAR was the only independent protective factor of postoperative neurological deficit [odds ratio (OR) =0.03, 95% confidence interval (CI): 0.0-0.61, P=0.02] and age was the only risk factor (OR =1.34, 95% CI: 1.11-1.62, P=0.002). The median follow-up time was 40 (interquartile range, 24-69) months and some of the patients received imaging follow-up. The overall survival rates at 5 and 10 years were 95.8%, and 95.8% in the CAR group and 84.1%, and 76.4% in the RIS group, with no significant difference (P=0.22). No cerebrovascular accident and reintervention occurred and 20 (90.9%) patients with residual false-lumen thrombus had reabsorption of thrombus during the follow-up period.ConclusionsCAR was a thorough technique and could protect patients from postoperative neurological deficit than RIS. Patients in either group could have a satisfying long-term prognosis after surviving from perioperative period. Most patients had reabsorption of residual false-lumen thrombus after anticoagulant therapy.

Project description:Background and purposeAdvancements in carotid revascularization have produced promising outcomes in patients with symptomatic carotid artery stenosis. However, the optimal timing of revascularization procedures after symptomatic presentation remains unclear. The purpose of this study is to compare in-hospital outcomes of transcarotid artery revascularization (TCAR), transfemoral carotid stenting (TFCAS), or carotid endarterectomy (CEA) performed within different time intervals after most recent symptoms.MethodsThis is a retrospective cohort study of United States patients in the vascular quality initiative. All carotid revascularizations performed for symptomatic carotid artery stenosis between September 2016 and November 2019 were included. Procedures were categorized as urgent (0-2 days after most recent symptom), early (3-14 days), or late (15-180 days). The primary outcome of interest was in-hospital stroke and death. Secondary outcomes include in-hospital stroke, death, and transient ischemic attacks. Multivariable logistic regression was used to compare outcomes.ResultsA total of 18 643 revascularizations were included: 2006 (10.8%) urgent, 7423 (39.8%) early, and 9214 (49.42%) late. Patients with TFCAS had the highest rates of stroke/death at all timing cohorts (urgent: 4.0% CEA, 6.9% TFCAS, 6.5% TCAR, P=0.018; early: 2.5% CEA, 3.8% TFCAS, 2.9% TCAR, P=0.054; late: 1.6% CEA, 2.8% TFCAS, 2.3% TCAR, P=0.003). TFCAS also had increased odds of in-hospital stroke/death compared with CEA in all 3 groups (urgent adjusted odds ratio [aOR], 1.7 [95% CI, 1.0-2.9] P=0.03; early aOR, 1.6 [95% CI, 1.1-2.4] P=0.01; and late aOR, 1.9 [95% CI, 1.2-3.0] P=0.01). TCAR and CEA had comparable odds of in-hospital stroke/death in all 3 groups (urgent aOR, 1.9 [95% CI, 0.9-4], P=0.10), (early aOR, 1.1 [95% CI, 0.7-1.7], P=0.66), (late aOR, 1.5 [95% CI, 0.9-2.3], P=0.08).ConclusionsCEA remains the safest method of revascularization within the urgent period. Among revascularization performed outside of the 48 hours, TCAR and CEA have comparable outcomes.
