Foreign body removal by snare loop: during intracranial stent procedure

Area of Science:

• Neurosurgery
• Vascular Neurology
• Interventional Neuroradiology

Background:

• Cerebrovascular diseases, such as internal carotid artery (ICA) stenosis, pose significant risks of ischemic stroke.
• Endovascular stenting is a common treatment for significant arterial stenosis.
• Stent deployment complications, including dislodgement, require prompt and effective management strategies.

Purpose of the Study:

• To report a case of successful retrieval of a dislodged intracranial stent.
• To describe the technique used for stent retrieval in the internal carotid artery (ICA).
• To highlight the safety and efficacy of snare-based retrieval in managing stent deployment complications.

Main Methods:

• A 52-year-old female patient with left border zone infarction underwent cerebral angiography.
• Significant stenosis was identified in the C6 segment of the left internal carotid artery (ICA).
• During attempted stenting, the stent dislodged into the C4 segment of the ICA and was successfully retrieved using a snare wire loop.

Main Results:

• Successful retrieval of the dislodged intracranial stent from the internal carotid artery (ICA) was achieved.
• The retrieval procedure using a snare wire was completed without any intra- or post-procedural complications.
• The patient tolerated the intervention well, with no adverse events reported.

Conclusions:

• Snare wire retrieval is a safe and effective technique for managing dislodged intracranial stents in the internal carotid artery (ICA).
• This method provides a viable solution for emergent situations arising during endovascular procedures.
• Prompt recognition and intervention are crucial for successful management of stent deployment complications.
