Summary
Super microsurgery enables the successful anastomosis of tiny blood and lymphatic vessels under 0.5 mm. This technique achieves a 100% patency rate, with procedures averaging just over 10 minutes.
Area of Science:
- Vascular Surgery
- Microsurgery
- Lymphatic Surgery
Background:
- Anastomosing vessels smaller than 0.5 mm presents significant challenges due to their delicate nature.
- Super microsurgery offers advanced techniques to overcome these difficulties.
Purpose of the Study:
- To detail the critical steps for performing super microsurgical anastomosis on veins and lymphatic vessels with diameters less than 0.5 mm.
- To report the outcomes of these super microsurgical procedures.
Main Methods:
- Describing precise needle insertion and manipulation techniques for vascular and lymphatic anastomosis.
- Utilizing specific instrument handling for vessel wall support and traction.
- Documenting the sequence of suturing for successful vessel connection.
Main Results:
- Achieved a 100% patency rate in 20 super microsurgical anastomosis procedures.
- Average anastomosis time was 11.35 minutes, with a range of 9 to 14 minutes.
- Experienced surgeons can complete an anastomosis in approximately 10 minutes.
Conclusions:
- The described super microsurgical techniques are effective for anastomosing small ( < 0.5 mm) lymphatic and venous vessels.
- Proficiency in these techniques allows for efficient and successful vessel anastomosis.
