Abstract

This report demonstrates the effectiveness of covered stents in surgery for a patient with thyroid cancer suspected of carotid artery invasion and poor tolerance to cerebral ischemia. Covered stents allowed safe management of blood vessels while maintaining blood flow, potentially expanding their applicability in head and neck tumor surgery.

Keywords: brain ischemia; carotid arteries; stents; thymic carcinoma; thyroid neoplasms.
