Where is basilar tip aneurysm?

Basilar artery: Basilar tip aneurysms, shown in the image and the video below, are the most common in the posterior circulation, accounting for 5% of all aneurysms. Clinical findings usually are those associated with SAH, although bitemporal hemianopsia or an oculomotor palsy may occur.

What causes basilar tip aneurysm?

Also, aneurysms in the posterior circulation (basilar, vertebral and posterior communicating arteries) have a higher risk of rupture. Risk factors for rupture include smoking, high blood pressure, drug or alcohol abuse, atherosclerosis, and genetic factors (1, 2).

What is a basilar tip?

Basilar tip aneurysm. One form of posterior circulation cerebral aneurysm which account for only the minority of aneurysms with 90% occurring in the anterior circulation. Cerebral aneurysms typically occur close to bifurcations, as with this one, which has the posterior cerebral artery immediately posteriorly.

How serious is a basilar tip aneurysm?

Ruptured basilar tip aneurysms may result in fatal subarachnoid hemorrhage (SAH) and mortality could be as high as 23%.

How common is basilar artery aneurysm?

Basilar trunk artery aneurysms (BTA) are extremely rare lesions that account for only 2.1% of all intracranial aneurysms [1]. To date, various names have been given to BTAs such as fusiform aneurysm, dolichoectatic artery, and serpentine aneurysm [2].

How is a basilar artery aneurysm treated?

Treating vertebral and basilar artery aneurysms by clipping is usually challenging; therefore, endovascular coil embolization has been widely used for these aneurysms [4]. However, coiling alone to treat complex vertebral and basilar artery aneurysms remains controversial because of the poor long-term stability.

Can a MRA detect a brain aneurysm?

The combination of magnetic resonance imaging (MRI) and magnetic resonance angiogram (MRA) can detect an aneurysm in 60-85% of cases. This screening test adds a few minutes of scanning time to the average MR examination.

Can an MRA without contrast detect an aneurysm?

Even though this method has many advantages for imaging the body and the extracranial blood vessels, it is not widely used for imaging intracranial vessels. The preferred method of imaging intracranial aneurysms with MRA is the 3D TOF technique, since it provides high-quality images, without contrast administration.

What is aneurysm of basilar artery?

Basilar trunk artery aneurysms are extremely rare lesions that account for only 2.1% of all intracranial aneurysms. They are mostly recognized in patients around the age of 60, show a slight male predominance, and are associated with high morbidity and mortality.

What is the treatment for aneurysm?

Treatment for Aneurysm depends on the location of the Aneurysm. An area of a vessel in the chest or abdomen where there is an Aneurysm might require a surgical procedure called endovascular stent graft. This is a minimally invasive procedure which repairs the damaged vessels and arteries and reduces the risk of infection,…

What is ruptured basilar artery aneurysm?

Abnormal bulging of the artery, known as an aneurysm, indicates a weakness in the wall of the artery and a risk of rupture of the artery. An aneurysm may be caused by an acute condition such as physical trauma to the head or by chronic problems such as high blood pressure or birth defects.

What is basal aneurysm?

An aneurysm is a basilar artery dysfunction which indicates a risk of rupture of the artery.

What is proximal basilar artery?

Proximal to its bifurcation into the terminal branches (ie, PCA), the basilar artery gives off the superior cerebellar arteries that supply the lateral aspect of the pons and midbrain and the superior surface of the cerebellum.
