Pseudoaneurysm of the internal mammary artery as an unusual cause of post-sternotomy hemorrhage: the role of multislice computed tomography in the diagnosis and treatment planning.
Pseudoaneurysm of the internal mammary artery (IMA) following median sternotomy is extremely rare. To date, the reported cases are only in single figures. The majority of these pseudoaneurysms were suspected from the clinical presentation, echocardiography or computed tomography (CT) but were only confirmed on contrast angiography. This case report demonstrates the current ability to carry out detailed vascular imaging on a 16-slice CT scanner. This accurate delineation of the pseudoaneurysm allowed targeted therapeutic embolization to be performed without unnecessary angiographic imaging.
