The fluid dynamics of simultaneous irrigation with negative pressure wound therapy.

Saline irrigation has been shown to be both experimentally and clinically efficacious in decreasing bacterial contamination as well as decreasing infection rates. The dynamics of irrigation delivery fall into two primary categories: simultaneous and intermittent irrigation. An important component to irrigation therapy is distribution of irrigation solution to hard-to-reach areas of a wound bed, including undermining and fissure-like structures.

Immunohistochemical identification of vascular endothelial growth factor in pig latissimus dorsi musculocutaneous flaps following ischemia-reperfusion injury.

Vascular Endothelial Growth Factor (VEGF), a potent angiogenic, mitogenic and vascular permeability enhancing protein, appears to improve survival of ischemic flaps independent of its route of administration. The purpose of this study was to examine VEGF protein expression in biopsies of surgical flaps with immunohistochemical techniques. In 6 male Yorkshire-type pigs, 10 cm x 15 cm Latissimus dorsi musculocutaneous flaps were elevated bilaterally.

Delay in unipedicled TRAM flap reconstruction of the breast: a review of 76 consecutive cases.

Since its introduction in 1982, the transverse rectus abdominis musculocutaneous (TRAM) flap has become the standard therapy in autogenous breast reconstruction. A lower rate of partial flap (fat) necrosis is associated with microvascular free-flap transfer compared with the conventional (unipedicled) TRAM flap because of its potentially improved blood supply. A TRAM flap delay before flap transfer has been advocated, especially in a high-risk patient population (obesity, history of cigarette smoking, radiation therapy, or abdominal scar).
