Area of Science:

  • Interventional Radiology
  • Vascular Surgery
  • Endovascular Therapy

Background:

  • Endovascular stent procedures can result in maldeployment or migration.
  • Managing these dislocated stents presents a clinical challenge.

Purpose of the Study:

  • To detail the experience with percutaneous management of dislocated endovascular stents.
  • To evaluate the efficacy and safety of these interventional techniques.

Main Methods:

  • Retrospective analysis of 28 patients with dislocated stents over a 6-year period.
  • Percutaneous techniques included balloon catheters, snares, forceps, or additional stent placement.
  • Management decisions were based on stent characteristics and location.

Main Results:

Related Experiment Videos

  • Successful percutaneous management in 92% (23/25) of dislocated stents.
  • Repositioning, anchoring with a second stent, or percutaneous removal were employed.
  • Two cases required minor surgical retrieval; complications were minimal.

Conclusions:

  • Percutaneous management is a highly effective and safe approach for dislocated endovascular stents.
  • These minimally invasive techniques are recommended as the primary therapy of choice.
