Simultaneous Carotid Endarterectomy and Ipsilateral Parotidectomy for Asymptomatic Carotid Artery Stenosis and Concurrent Warthin’s Tumor: A Multicenter Retrospective Case Series

Background: Management of high-grade carotid artery stenosis with concomitant ipsilateral parotid gland tumor presents a rare and challenging surgical condition. Due to the rarity of this dual pathology, standardized guidelines are lacking. Material and Methods: A retrospective study was conducted between January 2020 and May 2025. Six asymptomatic patients with significant carotid stenosis and coexisting ipsilateral Warthin’s tumor underwent simultaneous eversion CEA (carotid endarterectomy) and partial superficial parotidectomy/extracapsular enucleation via a single modified Blair’s incision. Results: Median follow-up was 43 months (range: 12–60 months). Postoperative and long-term survival at median follow-up was 100%, with a 5-year survival rate of 83.3% (one death at 50 months due to myocardial infarction). Disease-free survival at 5 years was 100% for Warthin’s tumor and 83.3% for carotid stenosis. No perioperative transient ischemic attacks (TIA), strokes, hematomas, salivary fistula or iatrogenic cranial nerve injuries occurred. Conclusions: In patients presenting with high-grade carotid stenosis and concomitant ipsilateral Warthin’s tumor, a simultaneous surgical approach is a feasible strategy. This approach eliminates the need for staged interventions, significantly reducing overall anesthetic risk, surgical burden, and healthcare resource utilization.
