Abstract：
Background and Objectives: The internal carotid artery (ICA) is a vascular structure that can be easily injured during sinus endoscopic procedures, and surgeons should be familiar with its anatomic variants. The aim of this study was to describe the anatomical variations in the internal carotid artery in relationship to sphenoidal sinuses, using computed tomography (CT). Materials and Methods: In this retrospective study, we evaluated the variations of the ICA in relationship to sphenoidal sinuses in a cohort of 600 patients who were assessed between January 2020 and December 2022 in \'Saint Spiridon\' Emergency Hospital, Iasi, Romania. Descriptive statistics were used to characterize our data. Results: The most prevalent anatomical variant was represented by intrasinusal septa with posterior insertion on the ICA (58.6%), followed by procident ICA (58%) and dehiscent ICA (52%). We could not find any statistical significance regarding demographic characteristics among groups. Conclusions: A thorough CT examination should be performed before functional endoscopic sinus surgery, with the identification of anatomical variants of the ICA, in order to prevent its injury with potentially fatal consequences.
摘要：
背景和目的：颈内动脉（ICA）是一种血管结构，在鼻窦内窥镜手术中很容易受伤。外科医生应该熟悉它的解剖变体。这项研究的目的是描述颈内动脉与蝶窦相关的解剖学变化，使用计算机断层扫描（CT）。材料和方法：在这项回顾性研究中，我们评估了在2020年1月至2022年12月期间在圣斯皮里顿急诊医院评估的600名患者中ICA与蝶窦关系的变化，Iasi,罗马尼亚。描述性统计用于表征我们的数据。结果：最普遍的解剖变异是在ICA上具有后插入的咬合内隔膜（58.6％），其次是积极的ICA（58％）和开裂的ICA（52％）。我们找不到关于群体间人口统计学特征的任何统计学意义。结论:功能性鼻内镜手术前应进行彻底的CT检查,随着ICA解剖变异的识别，以防止其伤害与潜在的致命后果。
