Résumé
A recent review of Vascular Study Group of New England data suggested that simultaneous endovascular treatment of tandem carotid lesions (TCAL: common carotid artery + internal carotid artery) is associated with a fourfold increase in perioperative neurologic events and death. However, given the small cohort, the effect of symptomatic status could not be evaluated. This study sought to determine the risk of simultaneous TCAL stenting in cohorts stratified by symptom status. Vascular Quality Initiative data (2005-2020) were queried for carotid stenting procedures (CAS). Emergent and bilateral procedures, patients with prior ipsilateral CAS, internal carotid artery lesions with stenosis <50%, and hybrid transcarotid procedures were excluded. The cohort was stratified by symptomatic status. The primary outcome was the composite of perioperative stroke and death. Predictors of stroke/death were determined with multivariable logistic regression for symptomatic and asymptomatic patients with TCAL forced into the models. There were 18,886 carotid arteries stented (18,441 patients): 18,077 (96%) with isolated carotid artery lesions and 809 (4%) with TCAL. Mean age was 70.0 ± 9.7. Symptomatic lesions were present in 58.9% of cases (isolated carotid artery lesions: 59.1% vs TCAL: 52.5%; P < .001). More TCAL arteries had a prior carotid endarterectomy (38.3% vs 23.8%; P < .001). TCAL had a higher perioperative stroke/death (3.4% vs 1.8%; P = .026) for asymptomatic lesions, but not symptomatic lesions (4.5% vs 3.7%; P = .41). TCAL were independently associated with stroke/death in asymptomatic patients (odds ratio, 1.85; 95% confidence interval, 1.03-3.33; P = .039) but not symptomatic patients (odds ratio, 1.22; 95% confidence interval, 0.76-1.97; P = .42). The addition of endovascular treatment of common carotid artery lesions with CAS is associated with almost double the risk of perioperative stroke/death in asymptomatic patients and should be avoided if possible. Treatment of TCAL is not associated with an increased risk of stroke/death for symptomatic lesions.

BACKGROUND
A recent review of Vascular Study Group of New England data suggested that simultaneous endovascular treatment of tandem carotid lesions (TCAL: common carotid artery + internal carotid artery) is associated with a fourfold increase in perioperative neurologic events and death. However, given the small cohort, the effect of symptomatic status could not be evaluated. This study sought to determine the risk of simultaneous TCAL stenting in cohorts stratified by symptom status.
METHODS
Vascular Quality Initiative data (2005-2020) were queried for carotid stenting procedures (CAS). Emergent and bilateral procedures, patients with prior ipsilateral CAS, internal carotid artery lesions with stenosis <50%, and hybrid transcarotid procedures were excluded. The cohort was stratified by symptomatic status. The primary outcome was the composite of perioperative stroke and death. Predictors of stroke/death were determined with multivariable logistic regression for symptomatic and asymptomatic patients with TCAL forced into the models.
RESULTS
There were 18,886 carotid arteries stented (18,441 patients): 18,077 (96%) with isolated carotid artery lesions and 809 (4%) with TCAL. Mean age was 70.0 ± 9.7. Symptomatic lesions were present in 58.9% of cases (isolated carotid artery lesions: 59.1% vs TCAL: 52.5%; P < .001). More TCAL arteries had a prior carotid endarterectomy (38.3% vs 23.8%; P < .001). TCAL had a higher perioperative stroke/death (3.4% vs 1.8%; P = .026) for asymptomatic lesions, but not symptomatic lesions (4.5% vs 3.7%; P = .41). TCAL were independently associated with stroke/death in asymptomatic patients (odds ratio, 1.85; 95% confidence interval, 1.03-3.33; P = .039) but not symptomatic patients (odds ratio, 1.22; 95% confidence interval, 0.76-1.97; P = .42).
CONCLUSIONS
The addition of endovascular treatment of common carotid artery lesions with CAS is associated with almost double the risk of perioperative stroke/death in asymptomatic patients and should be avoided if possible. Treatment of TCAL is not associated with an increased risk of stroke/death for symptomatic lesions.
