What is a Paraclinoid ICA aneurysm?
Paraclinoid aneurysm is defined as an aneurysm that originates at the internal carotid artery (ICA) distal to the proximal dural ring (PDR) and proximal to the posterior communicating artery (PCoA), which means both ophthalmic and clinoidal segments of the ICA.
What does a carotid aneurysm feel like?
Neck pain, a pulsatile mass and murmur at auscultation are the most common symptoms. ECCAs may exhibit severe clinical manifestations due to complications. Cases of rupture can be fatal. There is a risk of distal embolization and stroke in thrombosed cases.
What is Paraclinoid?
The paraclinoid segment of the carotid artery is defined as the portion between the proximal and distal dural rings, which have a potential space medially, the carotid cave. … The superior wall of the cavernous sinus is formed by 2 layers, a smooth superficial dural layer and a thin less-defined deep layer.
What is a Paraophthalmic aneurysm?
Paraophthalmic segment aneurysms include transitional, ophthalmic, and hypophyseal ICA aneurysms, as well as aneurysms of the dorsal wall of the ICA and carotid cave. 3 , 6 , 11.

Where is Paraclinoid ICA located?
Background: Paraclinoid or ophthalmic segment aneurysms arise from the internal carotid artery (ICA) between the roof of the cavernous sinus and the origin of the posterior communicating artery. Clinoid aneurysms arise between the proximal and distal carotid dural rings.
What is a hypophyseal aneurysm?
Background: Superior hypophyseal artery (SHA) aneurysms form a unique subgroup of paraclinoid aneurysms having a propensity to grow to a large size in the suprasellar region resulting in compression of the optic nerve, chiasma, and/or tract.
How can you prevent an aneurysm from rupturing?
The best way to prevent getting an aneurysm, or reduce the risk of an aneurysm growing bigger and possibly rupturing, is to avoid activities that could damage your blood vessels. … Preventing brain aneurysms

Can a small aneurysm burst?
The most common site of rupture of very small aneurysm was the ACoA. Rupture of small and very small aneurysms is unpredictable, and treatment may be considered in selected high-risk patients according to factors such as young age, ACoA location, and hypertension.
What size aneurysm should be treated?
After carefully assessing the evidence in the literature, they recommended that aneurysms measuring 5 to 7 mm should be treated if any risk factor (Type A or B) is present, while aneurysms <5 mm in diameter should only be treated in the presence of 2 or more Type A risk factors or in the presence of any of the Type B ...
