Dislodged Coronary Stents: The Presnaring Technique

Area of Science:

• Interventional Cardiology
• Medical Device Retrieval

Background:

• Coronary stents can become dislodged during procedures.
• Retrieval of dislodged stents is crucial to prevent complications.

Purpose of the Study:

• To describe and evaluate the presnaring technique for retrieving dislodged coronary stents.
• To demonstrate the feasibility of presnaring in clinical cases.

Main Methods:

• The presnaring technique involves snaring the coronary wire externally.
• The external snare loop is then advanced over the wire into the body.
• This facilitates the retrieval of the dislodged stent remaining on the wire.

Main Results:

• Successful retrieval of dislodged coronary stents was achieved in 2 described patient cases.
• The presnaring technique proved effective when the stent remained on the coronary wire.

Conclusions:

• Presnaring is a potentially valuable technique for retrieving dislodged coronary stents.
• This method is specifically useful when the stent is still engaged with the coronary wire.
