What causes basilar artery aneurysm?

Fusiform aneurysms generally occur in severely atherosclerotic basilar arteries; the cause of death most likely is atherosclerotic disease.

What causes spontaneous aneurysm?

High blood pressure is the leading cause of subarachnoid hemorrhage. Heavy lifting or straining can cause pressure to rise in the brain and may lead to an aneurysm rupture. Strong emotions, such as being upset or angry, can raise blood pressure and can subsequently cause aneurysms to rupture.

What is Perimesencephalic hemorrhage?

Perimesencephalic subarachnoid hemorrhage (PMSAH) is a distinct pattern of subarachnoid hemorrhage (SAH), which is centered on the basal cisterns around the midbrain.

How common is basilar artery aneurysm?

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.

How often do basilar aneurysms occur?

Intracranial aneurysms are common, with a prevalence between one and five per cent 1-3. Basilar tip aneurysms account for 7-8% of all intracranial aneurysms 1,4,5.

What part of the brain is the Intraparenchymal?

A parenchymal hemorrhage, or an intraparenchymal hemorrhage (IPH), is a bleed that occurs within the brain parenchyma, the functional tissue in the brain consisting of neurons and glial cells.

Does lack of sleep cause aneurysm?

Summary: Researchers identified insomnia as a potential risk factor for brain aneurysm, also called an intracranial aneurysm, and a type of stroke called an aneurysmal subarachnoid hemorrhage.

What are cisterns in brain?

The subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: “box”). As they are interconnected, their patency is essential for CSF circulation.

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.
