The CTPA shows the catheter in both pulmonary arteries, without any thrombosis.
Case Discussion
The migration of a VPS into both trunks of the pulmonary artery is a very rare complication.
The cause for the catheter migration was a penetration of the right subclavian vein, during the initial shunt placement.
Subsequent venous flow and negative intrathoracic pressure leads to the migration of the catheter.
