Mean Intercondylar Notch Width Index in Cases With and Without Anterior Cruciate Ligament Tears

Presented here is a 47-year-old man for whom right central venous chemoport catheterizationwas performed without radiological guidance. Within 8 days, the catheter became nonfunctionaland non-contrasted thoracic CT was performed to trace its course. The tip of thecatheter appeared to have perforated the opposite wall of the ipsilateral brachiocephalic veinand entered the adjacent brachiocephalic artery. It then maintained its course along the ascendingaorta to perforate, once again, the opposite wall of the aorta before finally resting inthe aortopulmonary soft tissue. Migration of chemoport is not uncommon, and may presentin many ways. However, it is rare for a migration to occur in the way described here andonly present with catheter blockage. Radiological guidance of any central vascular catheterizationgreatly reduces the risk of complications.
