Angiography and Intervention

Abstract

Angiography is used to detect functional morphological vascular changes. Thanks to modern cross-sectional imaging such as CT angiography and MR angiography, the indications for performing angiographic investigations have decreased. Arteriography is almost exclusively performed using the digital subtraction angiography (DSA) technique. Intra-arterial catheters are generally used to administer contrast agents. Only in exceptional cases is the artery directly punctured in order to inject contrast medium via a needle (needle angiography). DSA with the intravenous administration of contrast medium (i.v. DSA) is also only performed in exceptional cases.

The patient must be informed about the purpose of the procedure as well as the implementation, duration, alternatives, and risks. Only then is the patient’s consent considered legally valid (informed consent). The patient must give written consent.
