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

متن کاملMigration of Indwelling Central Venous Catheter and Fatal Hydrothorax
Central venous catheter complications can be related to insertion, indwelling, or extraction. Most of the times, immediate complications are anticipated and managed; whereas, delayed complications can go unnoticed. In the case discussed here, migration and dislodgement of catheter tip resulted in delayed hydrothorax and sudden death of a 9-month-old female infant.
