Abstract

Aside from haematomas, pseudoaneurysms (PSA) are considered the most frequent complications after catheter-guided interventions. Narrative compact short overview to describe aetiopathogenesis and characteristics of pseudoaneurysms and the options for diagnostic measures, therapy and its complications. Aetiopathogenesis: via the closed access site, the puncture channel, there is continuous bleeding out of the vessel which forms a pseudoaneurysm-associated cavity within the perivascular tissue. This is not surrounded by a regular vascular wall as in true aneurysms but is only formed by the surrounding tissue structures. However, this border is not sufficient and the pseudoaneurysm may extend, with diffuse bleeding episodes into the tissue. Thus, surrounding structures such as nerves and veins can be compressed by the expanding pseudoaneurysm, which can lead to irreversible damage. Diagnostic measures: duplex ultra-sonography absolutely predominant. CT-A, MR-A and DSA for specific problems and clinical case characteristics (e.g., accompanying diseases etc.) - DSA is to be linked with the option of image-guided intervention during the same session. by manual compression and subsequent dressing with compression, ultrasound-guided co...Continue Reading
