- Symptomatic aneurysms present with features of
- Compression of adjacent structures (veins or nerves)

This are false aneurysms which occur at the puncture site while doing angiography and angioplasty. It can also occur following injury to the artery following accidents.
If diagnosed immediately it can be closed with sonography compression. Injection of Thrombin can also be used in experienced hand. If this method fails then surgery is the other option especially when the aneurysm is big and causes skin necrosis.
