Abnormal origins of the vertebral artery with supra-aortic vessel variants are exceedingly uncommon. Herein, we present two cases of the vertebral artery originating from the right common carotid artery associated with the right subclavian artery arising separately as the initial branch of the aortic arch, followed by the right common carotid artery. We reviewed the embryology of the anomalous origins of the vertebral and subclavian arteries. These variants can significantly affect surgical planning and cause severe clinical symptoms.

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).
