From arteritis to mycotic aneurysm: visualization of the progression of mycotic aneurysm development following femoral arterial line insertion in an infant.
Although uncommon, mycotic aneurysms in infants can be lethal because of the high risk of rapid expansion and rupture. Most catheter-associated mycotic aneurysms reported in the first year of life develop following umbilical artery catheterizations. We describe the sonographic detection of an early stage mycotic aneurysm in a 4-month-old following femoral artery catheterization complicated by methicillin-resistant Staphylococcus aureus (MRSA) septicemia. We also describe the sonographic and radiographic progression of this mycotic aneurysm before surgery.
