Applications
DSA is primarily used to image blood vessels. It is useful in the diagnosis and treatment of:
- Arterial and venous occlusions, including carotid artery stenosis, pulmonary embolisms and acute limb ischaemia.
- Arterial stenosis, which is particularly useful for potential renal donors in detecting renal artery stenosis. DSA is the gold standard investigation for renal artery stenosis.
- Cerebral aneurysms and arterio-venous malformations (AVM).25545
