Mediastinitis Secondary to Peripherally Inserted Central Catheter Migration and Perforation after Minor Trauma: A Case Report

Introduction: The use of peripherally inserted central catheters (PICC) has been integral to the advancement of medical care in both in-patient and out-patient arenas.1 However, our knowledge of PICC line complications remains incomplete, particularly in regard to venous perforation and extraluminal migration. Utilization of displaced catheters harbors lethal complications and is an infrequently reported phenomenon, with traumatic etiologies only referenced as possible mechanisms; however, to date no formal cases have been reported.5,6 Case Report: We report a case of a fall associated with extraluminal PICC migration and perforation causing mediastinitis and severe sepsis after total parenteral nutrition (TPN) infusion in a 54-year-old woman. Our patient required a right-sided PICC for long-term home TPN due to severe malnutrition following gastric bypass surgery. During a routine home care visit our patient was found tachypneic, hypoxic, and short of breath. Computed topography imaging in the emergency department (ED) identified the injury, likely related to the recent fall. The patient experienced a complicated hospital course after removal of the PICC. Although rare, PICC line migrations and perforations cause serious complications that should be considered by emergency physicians evaluating patients with chronic indwelling vascular access. Conclusion: Given the efficacy and widespread use of PICC lines, we present this case as a rarely reported but life-threatening complication that requires particular attention. Emergency physicians should be aware of such PICC line complications when encountering patients with chronic indwelling vascular access.
