Abstract

Ana karotis
arter eksternal ve internal ayırımından önce dal vermez. Anatomik varyasyonları
nadirdir ve çoğu zaman postmortem anatomi çalışmalarında rastlantısal olarak
görülmektedir. Bu varyasyonlardan biri de genelikle eksternal karotis arterden
ayrılan superior tiroid arter (STA)’in ana karotis arterden köken almasıdır.
Biz bu yazımızda karotis arter hastalığı nedeniyle operasyona alınan ve ana
karotis arterden ayrılan STA varyasyonu olan hastada yapılan karotis
endarterektomiyi sunmaktayız. Serebrovasküler olay öyküsü olan 55 yaşında erkek
hastada yapılan karotis Doppler ultrasonografi ve karotis-vertebral
anjiyografisinde sol internal karotis arterde stenoz saptanması üzerine hastaya
operasyon planlandı. Sol karotis endarterektomi için yapılan boyun
diseksiyonunda ana karotis arterden köken alan variant STA görüldü. Klasik
yöntemle başarılı bir şekilde sol karotis endarterektomi yapıldı. Literatüre
bakıldığında STA’nın köken aldığı bölge ile karotis arterin bifurkasyonunun
seviyesi arasında bir ilişki olduğu görülmektedir. Yüksek seviyeli karotis
arter bifurkasyonu olan hastalarda STA ana karotis arterden köken alma
eğilimindedir. Karotis endarterektomide internal karotis artere erişim önemli
basamaklardan biridir. Bu nedenle ana karotis arterden köken alan STA varlığı
cerrahi erişimin zorluğunda öngörü sağlayabilir.

Successful Carotid Endarterectomy in a Patient with Superior Thyroid Artery Originated from Common Carotid Artery

Abstract

The common carotid artery typically does not have any
branches in the neck before it bifurcates into the external and internal
carotid arteries. Anomalies of the common carotid artery are rare and are
usually incidental findings in postmortem anatomical dissection. One of these
anomalies is the superior thyroid artery (STA), which occasionally originates
from external carotid artery, arising from the common carotid artery. In this
article, we present a successful carotid endarterectomy in a patient with an
aberrant branch from the common carotid artery. Because carotid and vertebral
artery Doppler ultrasonography and angiography showed subtotal occlusion at the
left internal carotid artery, carotid endarterectomy was planned. When the left
carotid artery was explored, the left STA was found arising from the common
carotid artery. Traditional carotid endarterectomy was successfully performed.
There is a relation between the origin of the STA and the site of bifurcation
of the carotid artery in the literature. The STA tends to arise from the common
carotid artery in the patients with high carotid bifurcation. Access to the
internal carotid artery is an important step of carotid endarterectomy.
Therefore, the finding of the STA originating from the common carotid artery
can provide an insight on difficulties with surgical access.
