Periprocedural complications in endovascular stroke treatment

Area of Science:

• Neurology
• Interventional Neuroradiology
• Vascular Surgery

Background:

• Endovascular stroke treatment is a critical neurointerventional emergency.
• Early recanalization within a specific time window is paramount for successful outcomes.
• Complications can significantly impact patient morbidity and mortality.

Purpose of the Study:

• To present imaging findings of periprocedural complications in endovascular stroke treatment.
• To classify and discuss various types of complications encountered during the procedure.
• To correlate imaging findings with existing literature on stroke treatment complications.

Main Methods:

• A retrospective analysis of 56 patients undergoing endovascular stroke treatment.
• Review of digital subtraction angiography (DSA) and CT imaging findings.
• Classification of complications into hemorrhagic, procedure/device-related, puncture site, and late-onset events.

Main Results:

• Detailed imaging characteristics of various periprocedural complications were identified.
• Hemorrhagic complications, device-related issues, and late-onset stenosis were observed.
• Findings were compared with previously reported literature on endovascular stroke treatment complications.

Conclusions:

• Understanding and recognizing periprocedural complications are vital for managing endovascular stroke treatment.
• DSA and CT imaging play a crucial role in diagnosing and characterizing these complications.
• Further research can refine management strategies for minimizing complication rates.
