Anatomical characteristics and morphometric analyses of the internal carotid artery using retrospective angiographic images

Abstract

Anatomical variations of the internal carotid artery (ICA) can cause complications during endovascular treatments. Therefore, the aim of this study was to investigate the features of the ICAs obtained from 2D digital subtraction angiography (2D DSA). MethodsThe morphometrics and angles of the ICA segments from 2D DSA images from a total of 100 patients (45 males and 55 females) were investigated. The lengths (L1-3), angles (A1-3), and diameters (D1-6) through the ICA measurement points (5 segments: C2 [petrous], C3 [lacerum], C4 [cavernous], C5 [clinoid], C6 (ophthalmic] were systemically recorded by two observers.
