In recent years carotid and vertebral artery dissections have been diagnosed more frequently, probably because new imaging techniques are more reliable and they are certainly less invasive. The cause of cervical artery dissections is largely unexplained but probably involves a combination of genetic and environmental factors such as trauma or infection. Most authors recommend intravenous heparin or low molecular weight heparin followed by oral warfarin to maintain INR between 2-3 for 3-6 months. If the artery has healed after 3-6 months of anti-coagulation all treatment can be stopped but if there is a remaining stenosis the patient can be put on aspirin 75-100 mg a day. The long-term prognosis of cervical artery dissection is favourable in the majority of patients. New dissections are uncommon.

Background: Sporadic aortic aneurysm and dissection (AAD) is a critical condition characterised by the progressive loss of vascular smooth muscle cells (VSMCs) and the breakdown of the extracellular matrix. However, the molecular mechanisms responsible for the phenotypic switch and loss of VSMCs in AAD are not fully understood.
Methods And Results: In this study, we employed a discovery-driven, unbiased approach.

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.

Aim: Vertebral artery dissection (VAD) is a rare cause of non-traumatic subarachnoid hemorrhage (SAH) with significant clinical implications. This study compared the clinical characteristics and outcomes of SAH from intracranial VAD rupture to those from other etiologies, primarily aneurysmal rupture.
Methods: This single-center retrospective cohort study at Okayama University Hospital included patients with non-traumatic SAH diagnosed between 2019 and 2023.

Carotid artery stenosis is a significant cause of ischemic stroke, often necessitating interventions like carotid artery stenting (CAS) to restore adequate blood flow. However, complications like intraprocedural arterial dissection can arise during the procedure. This report presents a case of intraprocedural arterial dissection during CAS using a CASPER Rx stent.

BACKGROUND The configuration of the hepatic arteries is known to vary substantially between individuals. Here, we report a rare retroperitoneal configuration of an accessory hepatic artery existing alongside a left and right hepatic artery branching from the proper hepatic artery. During routine dissection, we discovered an anomalous configuration of the hepatic arteries that does not fit the commonly used categorizations for abnormal hepatic vasculature.
