Lymphaticovenous anastomosis by microvascular technique.

Area of Science:

• Veterinary Surgery
• Vascular Surgery
• Lymphatic System Research

Background:

• Secondary lymphoedema is a debilitating condition often resulting from lymphatic system damage.
• Microsurgical techniques are crucial for restoring lymphatic function.

Purpose of the Study:

• To evaluate the efficacy and patency rates of lymphaticovenous anastomoses (LVA) in greyhounds.
• To identify key technical aspects and failure points in LVA procedures.

Main Methods:

• Development of basic LVA techniques in 60 dogs.
• Application and assessment of LVA in greyhounds, with patency evaluation at 1 week and 6-12 weeks.
• Detailed analysis of surgical techniques and reasons for anastomosis failure.

Main Results:

• Achieved a 74% patency rate for LVAs at 1 week post-surgery.
• Maintained a 66% patency rate between 6 and 12 weeks post-surgery.
• Identified specific technical points and common causes of failure in LVA.

Conclusions:

• Lymphaticovenous anastomoses demonstrate significant patency in greyhounds.
• The findings support the potential of LVA as a treatment for early secondary lymphoedema.
• Further refinement of surgical techniques can improve outcomes and reduce failure rates.
