Figure 7b. Catheter injury in a 58-year-old woman with hemoptysis after aortic valve replacement followed by placement of a Swan-Ganz catheter. (a) Axial CT image shows a pseudoaneurysm of a right pulmonary vessel. The pseudoaneurysm is contained by consolidated lung parenchyma. (b, c) Coronal thin-slab MIP (b) and coronal volume rendered (c) images show the feeding artery at the inferomedial border of the pseudoaneurysm (arrowhead). (d) Anteroposterior angiogram obtained with superselective injection of contrast medium shows the pseudoaneurysm and its feeding artery. The pseudoaneurysm was successfully treated with coil embolization.
