Dear Editor:

In-stent thrombosis (IST) is a rare but serious complication of carotid artery stenting (CAS) [1]. However, the risk factors for IST have not been determined. We present a case of IST following CAS in a patient with protein C deficiency.

A 40-year-old otherwise healthy woman was admitted to our hospital because of weakness in her left upper limb. She had cerebral infarction in her early thirties, but no sequelae remained, and she was not on anti-thrombotic agents. She had started taking oral contraceptives 7 days prior to her presentation. On admission, the neurological examination revealed left hemiparesis, hemihypoesthesia, and unilateral spatial neglect. Magnetic resonance imaging revealed an acute cerebral infarction and occlusion in the horizontal segment of the right middle cerebral artery (Fig. 1a, b). Thus, an emergent mechanical thrombectomy was planned. A right carotid angiography that was performed prior to thrombectomy revealed a filling defect at the origin...
