Percutaneous Management of Radial Artery Pseudoaneurysm: Two Illustrative Cases and a Literature Overview.

Radial artery pseudoaneurysm (PSA) is an uncommon but clinically relevant complication increasingly encountered with the expanding use of radial access in cardiology and critical care. Presentation and management vary widely according to etiology, patient frailty, and arterial wall integrity. We describe two representative cases: an elderly diabetic woman who developed a PSA after complex transradial coronary stenting and was successfully treated with selective coil embolization, and a man with cardiogenic shock and sepsis who developed a PSA following prolonged invasive monitoring and was managed with vascular plug devices. These cases illustrate the heterogeneous mechanisms leading to PSA and emphasize the need for individualized endovascular strategies in complex patients.
