Right Ventricular Pseudoaneurysm: An Unexpected Complication Following Insertion of Jugular Central Venous Line.

Background: Right ventricular pseudoaneurysm is a rare and poorly documented condition.

Case Summary: This paper reports a case of right ventricular pseudoaneurysm of iatrogenic origin, which developed after placement of internal jugular central venous catheter. The patient underwent successful percutaneous closure.

Discussion: The formation of a pseudoaneurysm is potentially fatal. The main causes are ischemic, postsurgical, infectious, and after percutaneous valve replacement. Diagnosis is based on nonspecific symptoms and multimodal imaging. Treatment may be medical, surgical, or percutaneous, depending on the clinic, imaging, and decision of the heart team.

Take-home Messages: Right ventricular pseudoaneurysm is a rare and poorly documented condition that can complicate even a routine procedure (eg, central venous line placement). Due to its lethal potential, treatment is primarily interventional, requiring careful multimodal imaging assessment. Coil embolization appears to be an effective and safe therapeutic option for managing small-sized pseudoaneurysms in patients at high surgical risk.
