A 50-year-old woman was referred to the noninvasive vascular laboratory for carotid artery evaluation because of a bruit in the neck. Color Doppler ultrasound examination demonstrated absence of the right common carotid artery and parallel internal and external carotid arteries originating at the brachiocephalic trunk. Computed tomography angiography further described anomalous anatomy, demonstrating a common origin of the innominate artery and left common carotid artery. Knowledge of such unusual anatomy may become valuable in future evaluation or treatment of this patient.

Objective: Prophylactic ligation of the external carotid artery (ECA) during oropharyngeal squamous cell carcinoma (OPSCC) resection is known to reduce severe postoperative oropharyngeal bleeding events, however, there is limited research on whether bleed rates vary between selective ligation of individual vessels or total ligation of the ECA. This study assesses outcomes related to total versus selective ligation of the ECA in patients who underwent transoral resection for OPSCC of the base of tongue or palatine tonsils.

The study aimed to develop a radiomics model to assess carotid artery plaque vulnerability using CTA images. It retrospectively included 107 patients with carotid artery stenosis who underwent carotid artery stenting (CAS) from 2017 to 2022. Patients were categorized into stable and vulnerable plaque groups based on pathology.

Purpose: A persistent trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Persistent trigeminal artery variants (PTAVs) terminate in the cerebellar arteries without connecting to the basilar artery; of these, the anterior inferior cerebellar artery (AICA) is the most common. AICA duplication is frequently observed.

Fluid administration is widely used to treat hypotension in patients undergoing veno-venous extracorporeal membrane oxygenation (VV-ECMO). However, excessive fluid administration may lead to fluid overload can aggravate acute respiratory distress syndrome (ARDS) and increase patient mortality, predicting fluid responsiveness is of great significance for VV-ECMO patients. This prospective single-center study was conducted in a medical intensive care unit (ICU) and finally included 51 VV-ECMO patients with ARDS in the prone position (PP).
