What surgical debridement method carries a higher risk of lymphedema?

Fascial excision of tissue carries a higher risk of lymphedema because this surgical approach involves the removal of deeper layers of tissue, including the fascia that surrounds muscles and other structures. This deeper tissue removal can disrupt lymphatic drainage pathways, leading to fluid accumulation and the potential development of lymphedema, particularly in extremities.

In contrast, superficial excisions and methods like mechanical debridement or hydrosurgical debridement may primarily target only the outer layers of skin or use fluid dynamics to remove necrotic tissue without significantly affecting deeper lymphatic structures. Understanding the anatomy and physiology of the lymphatic system is crucial in recognizing how surgical interventions can impact lymphatic flow and the subsequent risk of lymphedema.
