This study introduces a silk ligation delay technique for random flaps, enhancing flap survival and vascularization. The method proved safe and effective in clinical application.

Area of Science:

Plastic Surgery
Surgical Techniques
Tissue Engineering

Background:

Random flaps are crucial in reconstructive surgery.
Improving flap vascularization and survival is a key challenge.
Surgical delay techniques aim to precondition flaps for better outcomes.

Observation:

A new silk ligation delay technique was applied to expanded and unexpanded random flaps.
The procedure involved precise silk thread placement to ligate vessels incrementally.
Flap viability was monitored, and final transfer timing was determined by blood supply assessment.

Findings:

The silk ligation delay technique demonstrated a 100% flap survival rate in all patients.
No significant complications like infection, necrosis, or expander issues were observed, except for one expander rupture.
