A 64-year-old, right-handed man underwent endovascular treatment for internal carotid artery stenosis after experiencing a left-hemispheric transient ischemic attack. O-gas and H O positron emission tomography revealed slightly reduced cerebral blood flow (CBF), elevated cerebral blood volume, and severely reduced cerebral vasoreactivity in the ipsilateral hemisphere as determined by an acetazolamide challenge test. The patient underwent left carotid artery stenting (CAS) via a prefemoral approach under local anesthesia without any complications. Follow-up examinations performed 20 h postoperatively showed subarachnoid hemorrhage (SAH) and cerebral hyperperfusion syndrome (CHS) in the left frontal lobe. Although it is a relatively rare phenomenon, SAH resulting from CHS was determined to be specifically caused by CAS. In this case, the causes of SAH may have been related to multiple factors including increased regional CBF, loss of cerebrovascular autoregulation, contrast agent-mediated disruption of major cerebral vessels, and strong antiplatelet therapy.

Performance: Spontaneous dissections of the cerebral arteries are among the leading causes of stroke in young adults. They result from hemorrhage into the outer layers of the arterial wall, which can lead to stenosis or even complete vessel occlusion. Clinical presentations vary, ranging from localized pain to cerebral ischemic complications.

Cardiovascular disease remains a prominent cause of disability and premature death worldwide. Within this spectrum, carotid artery atherosclerosis is a complex and multifaceted condition, and a prominent precursor of acute ischaemic stroke and other cardiovascular events. The intricate interplay among inflammation, oxidative stress, endothelial dysfunction, lipid metabolism, and immune responses participates in the development of lesions, leading to luminal stenosis and potential plaque instability.

We report a rare case of a missed intracavernous internal carotid artery dissecting aneurysm occurring as a complication of the base of skull fracture with severe brain injury causing acute cavernous sinus syndrome with permanent vision loss. A 31-year-old Myanmar lady had an alleged motor vehicle accident and suffered severe traumatic brain injury with multiple intracranial bleeds, multiple facial bone and base of skull fractures, and limb fractures. At one week post-trauma, she had severe right eye proptosis with vision loss, ophthalmoplegia, chemosis, and high intraocular pressure.

A 2-day-old neonate was referred to the vascular surgery service owing to concerns of limb perfusion after entrapment of a microcatheter in the middle cerebral artery. The catheter was inserted via the umbilical artery to treat a vein of Galen arteriovenous malformation. This catheter inadvertently became entrapped owing to device failure, was cut at the insertion site, and left in situ for 3 months.

Background: An anomalous left vertebral artery (aLVA) can complicate aortic arch surgery. We examined the safety of various aLVA revascularization strategies during open total arch replacement.
Methods: We retrospectively evaluated 92 patients undergoing total arch replacement from January 2018 to May 2023 and identified 11 patients with aLVA.
