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
Causes
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:
Occasionally a 3 type, serpentine aneurysm has been classified as a separate entity .
Complications
- rupture
- distal thromboembolism
- pressure effects
