An Uncommon Complication of a Common Procedure.

Constant, safe and reliable endovascular access is necessary for patients' diagnosis and treatment. Endovascular access is possible with a variety of means, including central and peripheral venous catheters. Peripheral catheterization is an extremely common medical procedure and is considered risk-free or associated with minimal complications. Still potentially serious complications can occur. Authors describe a rare case of peripheral catheter migration at left pulmonary artery in an immunosuppressed patient.
