A 55 year-old man developed a sudden and severe headache followed by nausea and vomiting. Subarachnoid Hemorrhage - Anterior Communicating Artery Aneurysm. Axial CT scans without contrast: Note the ...

The posterior communicating artery is a potential location for an aneurysm, a bulging area in an artery. Aneurysms in this location make up about 25% of all intracranial aneurysms.

Thus, the rate of rupture is directly related to the size of the aneurysm.. Aneurysms usually occur at arterial bifurcations and mostly arise from the anterior circulation of the Circle of Willis (85% ...

Aneurysms of the aorta are known to occur in syphilis, but a cerebral aneurysm secondary to syphilitic vasculopathy has been reported only once, in a patient with an aneurysm of the posterior ...

Intravascular ultrasonography of the proximal left anterior descending coronary artery showed that the neck of the aneurysm was 10 mm in length. The lesions in the circumflex artery and the ...

The researchers report that older patients had larger aneurysms: aneurysms measuring 7 mm or larger were found in 18% of patients younger than 59 years, in 21.4% of those aged 50 to 59 years, in ...

An intracranial aneurysm is an enlargement of an artery in the brain. Depending on its shape, it can be classified as saccular, fusiform or blister-shaped. It can burst and result in immediate death.

ANY artery in the body has the potential of dilating abnormally if weakness develops in the artery wall. If this dilatation is of significant degree, the lesion is described as an aneurysm.

Brain aneurysms develop as a result of thinning artery walls, according to the clinic. A saccular aneurysm is a rounded sac containing blood that is attached to a main artery or one of its branches.
