ABSTRACT
OBJECTIVE:
Limited data are available to guide the choice of intervention for patients with radiation-induced carotid stenosis (RICS), either transcarotid artery revascularization (TCAR), transfemoral carotid artery stenting (TFCAS), or carotid endarterectomy (CEA). The purpose of the present study was to evaluate patients who had undergone these carotid artery interventions for RICS and the associated outcomes.METHODS:
Patients in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) carotid artery stenting surveillance project registry and the SVS VQI CEA modules who had undergone carotid artery intervention (TCAR, TFCAS, or CEA) for RICS were included. Those aged >90 years and those with concomitant interventions (eg, coronary bypass) were excluded. A composite of death, myocardial infarction (MI), and stroke was the primary outcome. The secondary outcomes included death, MI, stroke, cranial nerve injury (CNI), and other local and systemic complications. Multivariable logistic regression controlling for presenting symptomatic status and comorbid medical conditions was conducted for the outcome variables, except for death, which was analyzed using Cox regression modeling.RESULTS:
A total of 1927 patients with RICS had undergone CEA (n = 1172), TCAR (n = 253), or TFCAS (n = 502). The CEA group had a higher rate of diabetes (31% vs 25% for TCAR and 25% for TFCAS; P = .01), hypertension (85% vs 82% for TCAR and 79% for TFCAS; P < .01), and peripheral vascular disease (8% vs 4% for TCAR and 4% for TFCAS; P < .01). The TCAR and TFCAS groups had higher rates of coronary artery disease (21% for CEA vs 30% for TCAR and 29% for TFCAS; P < .01). The patients who had undergone TFCAS were more likely to have had symptomatic lesions (57% for TFCAS vs 47% for CEA and 41% for TCAR; P < .01) and prior stroke (55% for TFCAS vs 47% for CEA and 40% for TCAR; P < .001). The composite outcome occurred in 3.2% of TCAR patients, 11.2% of TFCAS patients, and 11.1% of CEA patients (P < .01) with an odds ratio of 0.27 for TCAR, 0.91 for TFCAS, and 1.00 for CEA. However, no differences in the individual outcomes were noted for any procedure. TCAR exhibited the lowest odds ratio for CNI (0.15) compared with TFCAS at 0.9, both relative to CEA (P = .03).CONCLUSIONS:
RICS patients treated by TCAR in the SVS VQI had the lowest risk of the composite of stroke, death, and MI and CNI. Therefore, TCAR might be the preferred treatment modality. Further comparative studies are needed to evaluate the long-term outcomes in this population and to elucidate the relationship of these procedures to the individual outcomes of stroke, MI, and death.Palabras clave
