Summary
Percutaneous techniques effectively retrieve intravascular foreign bodies and reposition endovascular stents with a high success rate. These minimally invasive procedures offer a safe and primary treatment option for dislodged devices and foreign objects.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Medical Device Retrieval
Background:
- Intravascular foreign bodies and misplaced endovascular prostheses pose significant clinical challenges.
- Traditional open surgical approaches carry higher risks and morbidity.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous interventional techniques for managing intravascular foreign bodies and dislocated endovascular stents.
- To assess the success rates and complication profiles of these minimally invasive procedures.
Main Methods:
- A 6-year retrospective analysis of 45 patients undergoing percutaneous treatment for intravascular foreign bodies or misplaced stents.
- Utilized multipurpose catheters, nitinol snare loops, and grasping forceps for retrieval and repositioning.
Main Results:
- Successful percutaneous intervention in 91.1% (41/45) of patients.
- High success rates for retrieval of catheter fragments (89.5%), guidewire fragments (100%), embolization coils (90.9%), endovascular stents (80%), and vena cava filters (100%).
- 100% success rate for repositioning dislocated endovascular stents, with no late complications reported.
Conclusions:
- Percutaneous techniques are highly effective for intravascular foreign body retrieval and endovascular stent repositioning.
- These minimally invasive methods demonstrate a low complication rate.
- Percutaneous intervention should be considered the primary treatment of choice for such conditions.
