Summary
Intraoperative carotid duplex scans effectively assess carotid endarterectomy, distinguishing reversible abnormalities from those needing revision. This helps ensure the technical success of the procedure.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Neurosurgery
Background:
- Carotid endarterectomy is a crucial procedure for stroke prevention.
- Accurate intraoperative assessment of technical success is vital to minimize complications.
- Duplex ultrasound offers real-time imaging and Doppler flow analysis.
Purpose of the Study:
- To evaluate the efficacy of intraoperative carotid duplex scans (ICDS) in assessing carotid endarterectomy.
- To correlate ICDS findings with intraoperative events, perioperative outcomes, and residual stenosis.
Main Methods:
- Retrospective review of 100 consecutive carotid endarterectomies with intraoperative duplex scans.
- Classification of B-mode and Doppler abnormalities.
- Correlation of ICDS results with clinical outcomes and postoperative imaging.
Main Results:
- 13% of ICDS revealed abnormalities, including spasm, flow issues, residual stenosis, and thrombosis.
- Two cases with significant abnormalities (stenosis, thrombosis) required immediate revision.
- Reversible abnormalities did not correlate with adverse perioperative events or residual stenosis.
Conclusions:
- Intraoperative carotid duplex scanning is a valuable tool for assessing the immediate technical adequacy of carotid endarterectomy.
- ICDS can differentiate reversible findings from those necessitating surgical revision, improving patient safety.
