Delayed stenosis following stentriever use in acute stroke intervention

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Neurology

Background:

• Endovascular embolectomy is a common procedure for treating acute vascular occlusions.
• Long-term surveillance for complications following endovascular embolectomy is crucial.

Observation:

• Two patients developed new stenosis in the previously treated vascular bed after endovascular embolectomy.
• The first case was an incidental finding during follow-up for cerebral aneurysms.
• The second case was detected during routine screening for stenosis.

Findings:

• Delayed post-embolectomy stenosis is a newly identified complication.
• This stenosis occurs in the vascular territory previously addressed by endovascular embolectomy.
• The phenomenon was observed in patients undergoing embolectomy for different indications.

Implications:

• This finding necessitates increased awareness and surveillance for delayed post-embolectomy stenosis.
• Further research is needed to understand the pathophysiology and optimal management of this condition.
• Consideration of this complication may influence long-term follow-up protocols for patients undergoing endovascular embolectomy.
