Vascular surgeons will very likely encounter only a handful 2 of these aneurysms
in their professional life.
Such structure may explain the tendency to intensify the development of aneurysms
in the abdominal aorta.
Patients having thoracic aortic aneurysms
are usually asymptomatic.
We report the experience of the senior author (AN) with surgical clipping of MCA aneurysms
and compare the outcome with the outcomes following endovascular treatment as published in literature.
We are extremely fortunate to have a renowned medical expert join us to share his knowledge about aneurysms
at our upcoming meeting at St.
originating in the PCA have particularities which distinguish them from aneurysms
in other intracranial circulation vessels (1).
10) True venous aneurysms
are rarely encountered compared to arterial aneurysm
, as well as can affect any veins including intracranial, cervical, thoracic, visceral, and upper and lower extremity veins; however, venous aneurysms
of the neck are rare due to low pressure in the vena cava system.
2,3,6 In early studies, stumps in the posterior circulation were often misinterpreted by neuro- surgeons as aneurysms
on the basis of the imaging findings.
The causes of brain aneurysm
are still unknown, but it has been determined that the following risk factors could contribute to weakness in the artery wall and increase the risk of a brain aneurysm
rupture: smoking, high blood pressure, drug abuse (particularly cocaine), heavy alcohol consumption, family history of brain aneurysm
, over 40 years old, gender (women have an increased incidence of aneurysms
, at a ratio of 3:2); traumatic head injury, tumors and inborn abnormality in the artery wall.
of blood vessels at the base of the brain are pathological focal outpouchings, usually found at the branching points of the arteries.
sup] Endovascular coiling thus provides a promising alternative approach to treat proximal LSA aneurysms
Isolated Iliac artery aneurysms
are rare at < 1%.
Danger signs Aneurysms
that cause pain or tenderness are more prone to rupture, as are larger aneurysms
or those that are expanding rapidly.
Medical image-based CFD has yielded much new knowledge about the role of hemodynamics in the pathophysiology of intracranial aneurysms
of the SVC are rare with approximately 36 cases reported at the time of this literature review .
