Successful Percutaneous Thrombectomy of the Left Pulmonary Artery in a Neonate After a Patent Ductus Arteriosus Clipping.

We report a neonate with a successful percutaneous thrombectomy of a total thrombotic occlusion of the left pulmonary artery (LPA) after a surgical clipping for a patent ductus arteriosus (PDA). We suspected the compression of the LPA by the clipping and postoperative hemodynamic instability caused the LPA obstruction. After the surgical removal of the PDA clip and division of the PDA, we could safely retrieve the LPA thrombus with a non-hydrodynamic thrombectomy catheter for coronary arteries.
