Abstract:

Introduction: сarotid chemodectoma is a benign, slowly growing, vascularized tumor that is one of the most common paragangliomas of head and neck. It is localized in the area of anterior surface of neck - in the area of carotid artery bifurcation. Despite the relative knowledge of the disease, surgical treatment of patients with these newgroth is difficult due to development of intraoperative hemorrhagic complications.

Aim: was to assess possibilities of primary embolization in the complex treatment of patients with chemodectoma.

Materials and methods: 70-year-old female patient was examined and treated. She was admitted with complaints on painless, pulsating, gradually progressive newgrowth of neck. After examination, carotid chemodectoma was diagnosed. The first stage was selective embolization of branches of the external carotid artery (ECA) feeding the tumor. Open chemodectomectomy was performed three days after embolization.

Results: analysis of literature sources and our case report showed that the volume of blood loss during an open operation for removal of chemodectoma using previous embolization is insignificant. This aspect also leads to a reduction of time of the intervention.

Conclusions: preoperative chemodectoma embolization significantly reduces the volume of blood loss and reduces the risk of developing other complications.
