False aneurysm of the pulmonary artery associated with cardiac catheterisation

A false aneurysm of the pulmonary artery developed in a 59 year old woman as a complication of right-sided cardiac catheterisation. This rare, life-threatening condition was successfully treated with coil embolisation of the feeding artery. Cardiologists and intensive care doctors should be aware of the possibility of the formation of false aneurysms of the pulmonary artery after Swan-Ganz and other right heart catheterisation. Appropriate therapy could be life-saving.
