OBJECTIVES: Carotid tandem lesions are a multilevel significant (>50%) atherosclerotic disease involving both the internal carotid artery (ICA) and either the ipsilateral common carotid artery (CCA) or the innominate artery (IA). These lesions may be challenging to treat. Current guidelines offer no definitive recommendation on the optimal treatment algorithm. The aim of this analysis was to assess the long-term outcome of patients undergoing surgical revascularisation for tandem lesions. METHODS: In two centres, consecutive patients who underwent carotid endarterectomy (CEA) for a symptomatic carotid artery stenosis between 2003 and 2017 were screened retrospectively for the presence of a carotid artery tandem lesion. All eligible patients were treated by a hybrid approach, consisting of retrograde stenting of the proximal CCA or IA followed by CEA. All patients had a yearly clinical check up including duplex ultrasound. The primary outcome was occurrence of any stroke, death, myocardial infarction (MI), or transient ischaemic attack (TIA) within 30 days. Secondary outcomes were any stroke, death, MI, or TIA and occurrence of restenosis ≥50% during follow up. RESULTS: Sixteen of 2368 symptomatic patients were included. Besides a high grade ICA stenosis, patients had a significant ipsilateral stenosis of the CCA (n = 13) or IA (n = 3). Within 30 days there were no deaths, strokes, or TIAs. Two patients had a clinical MI. During a median follow up of 73 (interquartile range 22-85) months, three patients died. One patient developed a symptomatic restenosis of the ICA (ipsilateral TIA). Two patients (without restenosis) developed an ipsilateral stroke and a MI. CONCLUSIONS: In this small case series, hybrid revascularisation of carotid tandem lesions in symptomatic patients seems feasible and safe. Long-term data show a relatively high number of any adverse events. These surgical outcomes need to be offset against the natural course in patients with a symptomatic carotid tandem lesion.
