2022年8月26日 · The external carotid artery (ECA) is one of the two terminal branches of the common carotid artery that has many branches that supplies the structures of the neck, face and head. The other terminal branch is the internal carotid (ICA), which is somewhat larger than the ECA, which supplies the intracranial structures.

2023年1月2日 · There is a problem diagnosing carotid dissection versus pseudo-obstruction. In a study in which the CTA-findings were compared to tDSA (golden standard for carotid lesions), the results showed that there was a high accuracy in diagnosing atherosclerotic occlusions and high grade stenoses of the internal carotid artery.

Anomalous external carotid artery (ECA)-internal carotid artery (ICA) anastomosis is a rare variant of cervical carotid artery formation that forms an arterial ring in the cervical segment, and its embryological mechanism is still unknown.

Knowledge of branching patterns of external carotid artery (ECA) is essential for planning and execution of head and neck surgeries. Digital subtraction angiography (DSA) images of 532 ECAs from 302 consecutive patients were retrospectively evaluated. We classify the branch variants of ECA into thre …

📢📢📢 DSCA: A Public Digital Subtraction Angiography (DSA) Dataset for Cerebral Artery Segmentation 🧠🧠🧠. The DSCA dataset consists of 58 patients with 224 DSA sequences, including 1792 images from the left and right hemispheres. Among them are 28 male and 30 female patients, with ages ranging from 9 to 81 years and an average age of 49.

2019年8月20日 · Transcranial Doppler (TCD) detected the blood flow in CCA, ICA and ECA on both sides. Digital subtraction angiography (DSA), computed tomography angiography (CTA) and Magnetic resonance angiography (MRA) offered dynamic and static images of intracranial and extracranial arteries and collateral circulation. All 16 patients had TCD examination.

该方法基于全脑动脉数字减影血管造影（DSA）图像，通过计算颈外动脉系统侧支血管生成比率（Collateralization Angiogenesis Ratio, CAR），量化烟雾病脑血运重建术后侧支血管的代偿情况，深入了解不同手术方式治疗效果，具有较高的临床应用价值，研究成果发表于 ...

2020年10月12日 · 1. The document describes the anatomy of the external carotid artery (ECA), including its origin, course, branches, and the branches of some its major vessels. 2. It provides detailed information on the origin, course, branches and territories of the superior thyroid, lingual, and ascending pharyngeal arteries. 3.

2019年6月30日 · Identifying collaterals from external carotid artery (ECA) is necessary before treatment of ophthalmic artery (OphA) aneurysm. We present a manual carotid compression test to verify collaterals in ophthalmic artery aneurysms, and evaluate its usefulness.

颈内动脉（internal carotid artery，ICA）分段方法有很多种，随着显微解剖、显微手术及脑血管介入的不断进步，分段方法不断演变，也逐渐贴近临床应用。 已经报道的ICA分段的方法，包括. ①Fischer的逆血流5段法（1938）； ②Gibo和Rhoton的顺血流4段法（1981）； ③Lasjaunias的胚胎学7分段法（1984）； ④Bouthillier顺血流7段法（1996）； ⑤Ziyal解剖结合脑血管造影的五段法（2005）； ⑥Shapiro NYU造影七段法（2014）； ⑦Labib基于内镜解剖的六段 …
