was changed:
Aneurysms are focal abnormal dilatation of a blood vessel. They typically occur in arteries, venous aneurysms are rare. Aneurysms may also occur in the heart.
Pathology
Pathological types
- true aneurysm
- false aneurysm (or pseudoaneurysm)
Aetiology
Atherosclerotic
Non-atherosclerotic
- congenital
- hypertension
-
vasculitis
- fibromuscular dysplasia
- infection: mycotic aneurysm, syphilis (luetic aneurysm)
- hereditary connective tissue disorders
- trauma
- iatrogenic
- myocardial infarction: may cause left a ventricular aneurysm
- flow-related (in cerebral AVM, contralateral ICA occlusion, etc.)
Morphology
Morphologically there are two main types of aneurysms. The morphology is not specific for any cause:
- saccular aneurysm: eccentric, involving only a portion of the circumference of the vessel wall (e.g. cerebral berry aneurysm)
- fusiform aneurysm: concentric, involving full circumference of the vessel wall
Occasionally a 3rd type, serpentine aneurysm has been classified as a separate entity 3.
Treatment and prognosis
Complications
- rupture
- distal thromboembolism
- pressure effects
History and etymology
The word aneurysm traces its roots back to ancient Greek, specifically the word ἀνεύρυσμα (aneurysma), literally translating as an 'aperture'. It is itself a compound construction, derived from two roots, 'ἄνω-' (ano) meaning 'up' and 'εὐρύς-' (eurys), meaning 'wide' 4,5.
