Abstract:
Catheter migration or catheter fracture and consequent migration of a fragment is a rare complication that occurs in 1% of the patients. Despite the low incidence, embolization may cause severe and potentially fatal complications, with the mortality rates varying between 24 and 60%. The gold standard treatment for this condition is the extraction of the fragmented catheter by the intravascular percutaneous route, through the common femoral vein. If it is not available, the extraction procedure must be performed through an alternative access. This article describes a fully successful removal of a fragmented catheter by percutaneous intravascular access obtained through the right subclavian vein.
