An Abnormal Course of the Internal Carotid Artery in the Neck

Arteria carotis interna anomalileri son derece nadir olup cerrahi sırasında beklenmedik komplikasyonlara neden olabilir Boyunda kitle şikayeti ile kulak burun boğaz kliniğine kabul edilen 83 yaşındaki hastanın boyun magnetik rezonans incelemesinde boyun sağ tarafında angulus mandibulanın inferiorunda, sternokleidomastoid kası anterolateralinde dev kitle lezyonu saptandı. Yapılan ince iğne aspirasyon biyopsisinde malign melanoma tespit edildi. Yapılan ileri tetkikler sonucu hastanın tanısı primeri bilinmeyen boyun metastazı olarak kabul edildi ve hastaya cerrahi sonrası kemoradyoterapi planlandı. Radikal boyun diseksiyonu sırasında arteria carotis internanın üzeri superiora doğru diseke edilirken arterin posteriora doğru sifon şeklinde anormal bir yaylanma yaptığı görüldü. Bu tür anomaliler nadir görülen varyasyonlar olmasına rağmen boyun cerrahisi sırasında hastanın yaşamını tehdit eden ciddi komplikasyonlara neden olabilir.

Boyunda Anormal Seyir İzleyen Arteria Carotis Interna

Internal carotid artery anomalies are extremely rare and may cause unexpected complications during surgery. The magnetic resonance imaging of the neck of a 83-year old patient was admitted to the ear,nose, and throat clinic with a mass in the neck, which was reported to be a giant mass lesion in the right side of the neck, inferior of the angle of mandible, to the anterolateral of the sternocleidomastoid muscle. After the fine needle aspiration biopsy the patient was thought to be a malignant melanoma case, making us plan chemoradiotherapy after the surgery. During the radical neck dissection, while the surface of the internal carotid artery was being dissected superiorly, it was noticed that the artery was springing abnormally in the form of the siphon posteriorly. Although these types of anamolies are rare variations, they can cause serious life-threatening complications during neck surgery.
