What is fusiform aneurysm?

The shape of an aneurysm is described as being fusiform or saccular, which helps to identify a true aneurysm. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the blood vessel. A saccular-shaped aneurysm bulges or balloons out only on one side.

What is the primary cause of fusiform aneurysms?

Fusiform aneurysms may occur due to a variety of underlying pathologies affecting the wall of the blood vessel. The most common proposed causes are dissection and atherosclerosis.

What is a basilar artery aneurysm?

The “basilar trunk artery” is the name given to the arterial segment located between the origin of the basilar artery and the origin of the superior cerebellar artery. Basilar trunk artery aneurysms (BTA) are extremely rare lesions that account for only 2.1% of all intracranial aneurysms [1].

How is a basilar artery aneurysm treated?

Endovascular embolization of cerebral artery aneurysms is now a well-known and alternative treatment to surgery (20, 21). As with other intracranial aneurysms not associated with fenestration, basilar artery fenestration aneurysms can also be treated endovascularly with GDCs.

Can you coil a fusiform aneurysm?

[14,24] Stenting following coiling is an alternative strategy of stent-assisted coil technique. This seems to be a feasible and practical method to remodel the parent artery and coil this type of aneurysms.

Can a fusiform aneurysm rupture?

Unruptured fusiform aneurysms not associated with atherosclerosis that are <7 mm in maximum diameter have a low risk of rupture or becoming symptom- atic during the first few years after presentation.

How serious is a 5 mm aneurysm?

aneurysms larger than 5 mm in patients younger than 60 years of age should be seriously considered for treatment; large, incidental aneurysms larger than 10 mm should be treated in nearly all patients younger than 70 years of age.

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%.

Is berry aneurysm a true aneurysm?

A false aneurysm, also known as pseudoaneurysm, involves only the outer layer of the artery (adventitia). Depending on their shape, they can be saccular or fusiform. Cerebral aneurysms are 90% saccular aneurysms (also known as berry aneurysms), unlike aortic aneurysms, which are about 94% fusiform.

How serious is a 6mm aneurysm?

These data suggest that small aneurysms < 6 mm in diameter are not innocuous and hazardous, and surgical treatment should be considered for small unruptured aneurysms even if they are less than 6 mm in diameter.

Where is a basilar tip aneurysm?

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.

What is basal aneurysm?

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

What is a fusiform aneurysm?

A fusiform aneurysm is a type of aneurysm characterized by a spindle-like shape when viewed in cross-section. It can be a cause for concern, depending on where in the body it is located, and in some cases emergency surgery may be required to correct it before it ruptures.

What is left vertebral aneurysm?

There is an aneurysm at the expected origin of the left vertebral artery. The aneurysm has extensive concentric mural thrombus and fills via a patent neck with a broad based attachment to the subclavian artery.

What is groin aneurysm?

Because of decreased blood flow, individuals with a femoral aneurysm may experience a sensation of tingling or numbness in the lower extremity below the location of the aneurysm. In many cases individuals with a femoral aneurysm located in the groin will feel resulting pain or numbness in the knee area, below the knee or in the lower thigh.
