Area of Science:

  • Microsurgery
  • Surgical Innovation
  • Experimental Models

Background:

  • Existing rat lymph node flap models lack skin paddles.
  • A need exists for versatile lymph node flap models in rats for research.

Purpose of the Study:

  • To describe a novel cervical lymph node-adipo-cutaneous flap model in rats.
  • To evaluate its suitability for future experimental studies.

Main Methods:

  • Anatomical investigation of rat cervical lymph nodes.
  • Harvesting and transfer of a lymph node flap with a skin paddle (1.5 × 0.5 cm).
  • Assessment of lymphatic flow restoration and histological analysis at 30 days post-operation.

Main Results:

  • The flap is based on a consistent adipofascial structure (innominate septum).
  • Flap microvascular and lymph node anatomy (2-3 nodes) was constant.
  • All flaps survived with minimal donor-site morbidity; lymphatic flow restoration was observed.

Conclusions:

  • The described flap is safe, reliable, and versatile.
  • It offers constant anatomy and includes a skin paddle.
  • This supermicrosurgical model is suitable for autologous lymph node transplantation in rats.
