Summary
Endoscopic radial artery harvesting is a feasible technique, showing high patient satisfaction despite a learning curve and some nerve paresthesias. Further studies are needed to confirm long-term graft patency.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Techniques
- Vascular Grafting
Background:
- The open method for radial artery harvesting can lead to notable esthetic concerns and neurologic complications.
- Improving surgical techniques is crucial for patient outcomes and satisfaction in coronary artery bypass grafting.
Purpose of the Study:
- To assess the feasibility of endoscopic radial artery harvesting.
- To evaluate the potential for improved esthetic results and reduced neurologic complications compared to open harvesting.
Main Methods:
- A total of 54 patients underwent endoscopic radial artery harvesting using standard endoscopic equipment and a Harmonic Scalpel.
- Preoperative Allen tests and duplex ultrasonography confirmed adequate ulnar collateral flow.
- Mean follow-up was 13 months, with the nondominant arm used for harvesting.
Main Results:
- The procedure involved a 3-cm wrist incision, with division at the elbow achieved endoscopically or via a small counterincision.
- Mean harvest time decreased significantly with experience, from 85 to 25 minutes.
- Complications included superficial radial nerve paresthesia in 15 patients (4 clinically relevant), with 87% patient enthusiasm.
Conclusions:
- Endoscopic radial artery harvesting is a feasible surgical option.
- The technique demonstrates a learning curve and did not completely eliminate nerve paresthesias but achieved high patient satisfaction.
- Long-term patency rates require further investigation.
