Summary
This study shows a new diode laser device is effective for laser-assisted vascular anastomoses (LAVA). LAVA significantly reduces procedure time compared to conventional microvascular suture anastomosis (CMSA) with similar patency and aneurysm rates.
Area of Science:
- Biomedical Engineering
- Surgical Technology
- Laser Medicine
Background:
- Conventional microvascular suture anastomosis (CMSA) is time-consuming.
- Advancements in laser technology offer potential for improved surgical techniques.
Purpose of the Study:
- To evaluate the clinical utility of a novel diode laser device for microvascular end-to-end anastomoses.
- To compare laser-assisted vascular anastomoses (LAVA) with CMSA.
Main Methods:
- A new diode laser device (830 nm, 190 mW CW) with a contact ceramic tip was developed.
- Vascular anastomoses were performed using LAVA and CMSA.
- Patency, aneurysm formation, histological features, tensile strength, and bursting pressure were assessed post-procedure.
Main Results:
- LAVA reduced anastomosis time by nearly half compared to CMSA.
- Both methods showed similar patency rates and aneurysm formation.
- LAVA demonstrated superior histological outcomes, including smoother inner surfaces and reduced inflammation.
Conclusions:
- The novel diode laser device is a viable tool for microvascular surgery.
- LAVA offers significant time savings and improved histological results over CMSA.
- The diode laser contact method shows clinical promise for microvascular procedures.
