Summary
Microvascular thermic sleeve anastomosis using bipolar coagulation achieved high arterial patency (100%) and good venous patency (78%). Lumen integrity and tissue changes were assessed post-surgery.
Area of Science:
- Vascular Surgery
- Microsurgery
- Surgical Technology
Background:
- Microvascular anastomosis is crucial for reconstructive surgery.
- Minimally invasive techniques are sought to improve outcomes.
- Bipolar coagulation offers precise thermal control.
Purpose of the Study:
- To evaluate the efficacy of microvascular thermic sleeve anastomosis.
- To assess patency rates and lumen integrity after the procedure.
- To investigate histopathological changes associated with the technique.
Main Methods:
- Experimental investigation of microvascular thermic sleeve anastomosis.
- Utilized bipolar coagulation for vessel sealing.
- Assessed arterial and venous patency rates.
- Analyzed lumen contour using plastic casts at multiple postoperative intervals (3 hours to 30 days).
- Conducted histopathological studies to examine intussusception and thermal effects.
Main Results:
- Achieved 100% patency for arteries (approx. 1.0 mm diameter).
- Achieved 78% patency for veins (approx. 0.7 mm diameter).
- Lumen contour remained consistent over 30 days post-surgery.
- Histopathology revealed changes related to intussusception and heating spots.
Conclusions:
- Microvascular thermic sleeve anastomosis with bipolar coagulation is a viable technique.
- Demonstrates excellent arterial patency and acceptable venous patency.
- Further investigation into histopathological effects is warranted.
