[Pedicled Omentum Flaps in the Management of Deep Sternal Wound Infections]

Coverage of a deep sternal wound infection with a greater omentum flap. Due to a persistent infection caused by an infected aortic prosthesis, the primarily performed reconstruction with a latissimus dorsi flap had to be revised, and an alternative solution had to be found.

A deep sternal wound infection is a rare but devastating complication following median sternotomy. If the commonly used muscle flap is not sufficient and artificial material is still present in the wound, for instant drivelines or a vascular prosthesis, the greater omentum flap is a useful option due to its immunologic capacity.

After an exploration of the persisting infected deep sternal wound, a radical debridement is performed followed by a jet lavage. The soft tissue from the greater omentum is prepared via median laparotomy and transferred through a tunnel created in the diaphragm. Then it is pulled into the wound cavity and can be used for tension-free sheathing of the aortic prosthesis. The previously used muscle flap can additionally be used for superficial soft tissue coverage.

Due to its immunologic competence, the greater omentum flap is a good treatment alternative to the commonly used muscle flaps in defects with infected artificial material.
