title: Malpositioned or dislocated aortic endoprostheses: repositioning using percutaneous pull-down maneuvers.
abstract: OBJECTIVE
  To present the capabilities and potential complications of 2 percutaneous techniques for repositioning malpositioned or dislodged aortic endografts.
  
  
  METHODS
  Seven male patients (median age 67.9 years, range 59 to 78) required correction of misplaced or dislocated endografts in the thoracic (n = 1) or infrarenal abdominal aorta (n = 6). In 1 patient, an infrarenal bifurcated stent-graft was mistakenly deployed across a renal artery; repositioning was accomplished by tugging caudally on a guidewire placed across the endograft bifurcation and exteriorized from both femoral arteries. An inflated balloon catheter was used to reposition 3 dislocated aortic devices (1 thoracic, 2 infrarenal) and 3 iliac graft limbs that had disconnected from the main graft body 6 to 12 months after implantation.
  
  
  RESULTS
  Repositioning maneuvers were successful in all cases, with the devices being moved from 5 to 27 mm (median 7.8 mm). There were no procedure-related complications.
  
  
  CONCLUSIONS
  Nonsurgical repositioning of misplaced aortic prostheses is technically feasible in individual cases. The risk associated with the procedure, however, cannot yet be evaluated.
