Aberrant anatomical variation of the vertebral artery (VA) from an internal carotid artery (ICA) is considered a rare finding. The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

Background: Intravascular injection of liquid adhesive hemostats is a rare but serious complication that can result in cerebral thromboembolism.
Observations: A 64-year-old female underwent orbitozygomatic craniotomy for posterior communicating artery aneurysm clipping with the routine use of a flowable hemostatic agent during extradural dissection. After placement of the aneurysm clip, flow was confirmed through the parent vessel and nearby branches.

Basilar artery perforator aneurysms (BAPAs) are rare and may be occult on initial imaging due to their small size and susceptibility to intermittent thrombosis.1 2 Conventional treatments for aneurysms (eg, clipping or coiling) have proved challenging.3 Recently, endovascular electrocoagulation has been shown to be effective for BAPAs.

Stents are increasingly used for coiling difficult aneurysms, to reduce the risk of recurrences, or to modify blood flow. Currently, available bifurcation aneurysm models are ill-suited to assess stent performance before clinical use. We designed a new animal model of wide-neck canine Y-type bifurcation aneurysm (such as middle cerebral artery (MCA) bifurcation) and previously reported one of T-type (such as basilar bifurcation).

Article Synopsis
- Basilar artery strokes are hard to diagnose due to their varied symptoms, but quick identification is crucial to prevent serious issues.
- A 28-year-old woman was admitted after experiencing convulsive activity and confusion, which led to a diagnosis of nonocclusive basilar artery thrombosis and additional strokes from imaging tests.
- Her recent preeclampsia highlights the importance of recognizing pregnancy-related stroke risks and the need for prompt imaging to improve outcomes in such cases.
