[Pericardiocentesis - step by step]. / Perikardpunktion ­ Schritt für Schritt.

ABSTRACT

A pericardial effusion can be caused by malignant, infectious and autoimmune diseases or by trauma, such as a coronary artery rupture during a cath procedure. In the case of a cardiac tamponade a pericardiocentesis has to be performed immediately.Additionally, a pericardiocentesis may also be performed for diagnostic purposes. However, since histologic and microbiologic findings are rarely pointing to hitherto unsuspected results, the risk of the procedure must very carefully be weighed against its benefits. The risks of a pericardiocentesis include injuries to the lungs and liver as well as the heart itself, such as puncture of the right ventricle or the rupture of a coronary artery.This article is a step-by-step description of how to safely perform an ultrasound-guided pericardiocentesis.
