Conventional Angiography, or more specifically Digital Subtraction Angiography (DSA) can be used for both diagnostic and interventional Angiography. Its high spatial and temporal resolution have maintained DSA as a very important tool. In conventional angiography the patient is catheterized, usually via the common femoral artery in the groin. Wires, catheters, clot retrieval devices, stents and anuerysm coils can be passed to the vessel of interest with this access.
