BACKGROUND AND PURPOSE Studies have shown that the occurrence of brain aneurysms and risk of rupture vary between locations. However, the reason that aneurysms at different branches of the cerebral arteries have different clinical presentations is not clear. Because research has indicated that aneurysm hemodynamics may be one of the important factors related to aneurysm growth and rupture, our ...

extremity weakness. Brain MRI showed multiple scattered embolic infarctions on left middle cerebral artery (MCA) territory with A-com aneurysm. Transfemoral cerebral angiography was tried and failed due to stenosis of distal aortic arch (Fig. 1). Therefore, cerebral angiography was performed through right radial artery and revealed 3.2×2.5 mm-sized anterior communicating (A-com) aneurysm with i...

We describe a case of a huge intramural hematoma in a thrombosed middle cerebral artery aneurysm. A 47-year-old female patient with liver cirrhosis and thrombocytopenia presented to the neurosurgical unit with a 5-day history of headache and cognitive dysfunction. Magnetic resonance imaging and computed tomography of the brain showed a thrombosed aneurysm located in the right middle cerebral ar...

background: aneurysm is a blood-filled bulge in the wall of vessels that occurred in abdominal aortic and cerebral vessels. the dilation of artery leads to aneurysm. methods: three dimensional modelling was utilized for a patient with cerebral aneurysm and a normal subject, and additional fluid-structural interaction simulation was performed. we consider pulsatile blood velocity as inlet, and b...

The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of ...

A 60-year-old woman with a family history of aortic dissection in her mother was investigated for dysphagia. Her scan showed right arch large Kommerell’s diverticulum causing esophageal compression. left vertebral artery, which originated abnormally low the thorax, embolized preoperatively to limit operative difficulties. Two weeks later, thoracotomy allowed resection aneurysm an associated car...
