The cervical course of the internal carotid artery is almost straight in contrast to the intracranial portions which are highly tortuous. The incidence of variations in the cervical course of the internal carotid artery of the population is approximately 10-40 percent. In this case report, a 76-year-old female patient with a pulsatile mass at the posterior oropharyngeal wall and anterior neck was presented. Physical examination revealed a pulsatile anterior neck mass, and a pulsatile mass at the right posterior wall of the oropharynx. Imaging revealed a bilateral tortuous internal carotid artery and segmental left internal carotid arterectomy and distal internal carotid artery - lateral common carotid artery anastamosis were performed with no postoperative complications.

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.

Transcarotid artery revascularization (TCAR) is a novel method to treat severe stenosis of the carotid artery with minimal embolization. During TCAR, flow reversal system redirects blood from the internal, external, and common carotid arteries into the femoral vein through a filter system to prevent debris and microparticles from entering the cerebral circulation. Transcranial Doppler (TCD) monitoring allows real-time detection of blood flow in the cerebral arteries during the operation and informs the surgeon of flow changes or possible emboli.

Objective: Early identification of risk factors associated with early neurological deterioration (END) in patients with acute minor stroke and large vessel occlusion (LVO) receiving intravenous thrombolysis (IVT) could assist in formulating treatment decisions.
Methods: Consecutive patients with acute minor stroke and LVO were extracted from a single-center prospective database spanning January 2020 to December 2023. END was defined as an increase of ≥ 4 points in the National Institutes of Health Stroke Scale (NIHSS) score from baseline, or ≥ 2 points in any single NIHSS item, within 24 hours of the IVT.

Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.
