Aortic aneurysm

aortic aneurysmsaortic aneurismaneurysm
Although they may occur in any blood vessel, particularly lethal examples include aneurysms of the Circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta, and abdominal aortic aneurysms.
Most AAA are true aneurysms that involve all three layers (tunica intima, tunica media and tunica adventitia).

Pseudoaneurysm

aneurysm, falsefalse aneurysmfalse lumen
A false aneurysm, or pseudoaneurysm, is a collection of blood leaking completely out of an artery or vein, but confined next to the vessel by the surrounding tissue.
It may be pulsatile and can resemble a true aneurysm.

Coronary catheterization

coronary angiographycoronary angiogramcardiac catheterization
Pseudoaneurysms can be caused by trauma that punctures the artery, such as knife and bullet wounds, as a result of percutaneous surgical procedures such as coronary angiography or arterial grafting, or use of an artery for injection.
Specifically, coronary catheterization is a visually interpreted test performed to recognize occlusion, stenosis, restenosis, thrombosis or aneurysmal enlargement of the coronary artery lumens; heart chamber size; heart muscle contraction performance; and some aspects of heart valve function.

Charcot–Bouchard aneurysm

Charcot-Bouchard aneurysmmicroaneurysmmicroaneurysms
Charcot–Bouchard aneurysms are aneurysms of the brain vasculature which occur in small blood vessels (less than 300 micrometre diameter).

Intracranial aneurysm

brain aneurysmcerebral aneurysmaneurysm
Cerebral aneurysms, also known as intracranial or brain aneurysms, occur most commonly in the anterior cerebral artery, which is part of the circle of Willis.
Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture.

Atherosclerosis

atheroscleroticatherogenesisatherosclerotic plaques
True aneurysms include atherosclerotic, syphilitic, and congenital aneurysms, as well as ventricular aneurysms that follow transmural myocardial infarctions (aneurysms that involve all layers of the attenuated wall of the heart are also considered true aneurysms).
If the enlargement is beyond proportion to the atheroma thickness, then an aneurysm is created.

Embolism

embolicerebral embolismembolus
Aneurysms can also be a nidus (starting point) for clot formation (thrombosis) and embolization.
In the first three months after infarction, left-ventricle aneurysms have a 10% risk of emboli forming.

Abdominal aortic aneurysm

Although they may occur in any blood vessel, particularly lethal examples include aneurysms of the Circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta, and abdominal aortic aneurysms.
The first historical records about AAA are from Ancient Rome in the 2nd century AD, when Greek surgeon Antyllus tried to treat the AAA with proximal and distal ligature, central incision and removal of thrombotic material from the aneurysm.

Autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidneyADPKDpolycystic kidney disease
It is also the most common of the inherited cystic kidney diseases — a group of disorders with related but distinct pathogenesis, characterized by the development of renal cysts and various extrarenal manifestations, which in case of ADPKD include cysts in other organs, such as the liver, seminal vesicles, pancreas, and arachnoid membrane, as well as other abnormalities, such as intracranial aneurysms and dolichoectasias, aortic root dilatation and aneurysms, mitral valve prolapse, and abdominal wall hernias.

Mycotic aneurysm

abnormal dilatation of blood vessels due to infection
Infection. A mycotic aneurysm is an aneurysm that results from an infectious process that involves the arterial wall.
An infected aneurysm is an aneurysm arising from bacterial infection of the arterial wall.

Rasmussen's aneurysm

Rasmussen's aneurysm is a pulmonary artery aneurysm associated with a cavitary lung lesion.

Computed tomography angiography

CT angiographycomputed tomography (CT) angiographyCT
Computed tomography angiography (CTA) is an alternative to traditional angiography and can be performed without the need for arterial catheterization.
Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls), and stenosis (narrowing of vessel).

Aneurysm of sinus of Valsalva

Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body.

Magnetic resonance imaging

MRIMRI scanmagnetic resonance imaging (MRI)
Abdominal aortic aneurysm involves a regional dilation of the aorta and is diagnosed using ultrasonography, computed tomography, or magnetic resonance imaging.
Magnetic resonance angiography (MRA) generates pictures of the arteries to evaluate them for stenosis (abnormal narrowing) or aneurysms (vessel wall dilatations, at risk of rupture).

Abdominal aortic aneurysm involves a regional dilation of the aorta and is diagnosed using ultrasonography, computed tomography, or magnetic resonance imaging.

Familial thoracic aortic aneurysm

In the aorta, this can result in the formation of a fusiform aneurysm.

Flow diverter

Flow diverter can be used but not without complications sometimes.
A flow diverter is an endovascular prosthesis used to treat intracranial aneurysms.

Clipping (medicine)

Surgical clipping was introduced by Walter Dandy of the Johns Hopkins Hospital in 1937.
Clipping is a surgical procedure performed to treat an aneurysm.

Surgical clipping was introduced by Walter Dandy of the Johns Hopkins Hospital in 1937.
Dandy is credited with numerous neurosurgical discoveries and innovations, including the description of the circulation of cerebrospinal fluid in the brain, surgical treatment of hydrocephalus, the invention of air ventriculography and pneumoencephalography, the description of brain endoscopy, the establishment of the first intensive care unit (Fox 1984, p. 82), and the first clipping of an intracranial aneurysm, which marked the birth of cerebrovascular neurosurgery.

Anterior communicating artery

anterioranterior communicating arteries
Aneurysms of the anterior communicating artery are the most common circle of Willis aneurysm and can cause visual field defects such as bitemporal heteronymous hemianopsia (due to compression of the optic chiasm), psychopathology and frontal lobe pathology.

Vasa vasorum

blood vessels supplying the artery itselfsmall blood vesselsvasa-vasorum
The pressure of blood within the expanding aneurysm may also injure the blood vessels supplying the artery itself, further weakening the vessel wall.

Lysyl oxidase

LOXprotein-lysine 6-oxidaseLOX (gene)
Copper deficiency. A minority of aneurysms are caused by copper deficiency, which results in a decreased activity of the lysyl oxidase enzyme, affecting elastin, a key component in vessel walls.
This resulted in lathyrism, characterized by poor bone formation and strength, hyperextensible skin, weak ligaments, and increased occurrence of aortic aneurysms.

Intracranial hemorrhage

intracranial bleedingintracranial haemorrhageintracranial hematoma
When the wall shear stress reaches its limit, the aneurysm ruptures, leading to intracranial hemorrhage.
It can result from physical trauma (as occurs in head injury) or nontraumatic causes (as occurs in hemorrhagic stroke) such as a ruptured aneurysm.

Cone was 4–1 with a 2.02 ERA when he was diagnosed with an aneurysm in his arm in 1996 and went on the disabled list for the majority of the year.
