Postoperative Cervical Haematoma Complicated by Ipsilateral Carotid Thrombosis and Aphasia after Anterior Cervical Fusion: A Case Report

Abstract

Hematoma alone is the most common vascular complication reported after anterior cervical decompression and fusion (ACDF). We present this case to report the occurrence of postoperative cervical hematoma complicated by ipsilateral carotid thrombosis and aphasia after an uncomplicated C4–6 ACDF. This is a case of a 65-year-old woman who underwent revision fusions of the C4-5 and C6-7 levels complicated by postoperative cervical hematoma and carotid thrombosis. The patient's history, clinical examination, imaging findings, and treatment are reported. The revision fusions were performed and deemed routine. Approximately eight hours later 200 mL of blood was evacuated from a postoperative cervical hematoma. The patient became unresponsive and disoriented a few hours after evacuating the hematoma. Computed tomography and magnetic resonance imaging of the brain were normal, but magnetic resonance angiography demonstrated total occlusion of the left carotid artery. Thrombectomy was performed and the patient was discharged without residual deficits. At the latest followup she is fully functional and asymptomatic in her neck. We suggest, after evacuating a cervical hematoma, an evaluation of the carotids be made with MRA or cerebral angiography, as this may demonstrate a clot before the patient develops symptoms.
