Polypoid granulation tissue in pressure ulcers: Significance of describing individual ulcers
この論文をさがす
説明
Granulation tissue formation is required for the healing of deep pressure ulcers. The wound healing process is often delayed at the stage of granulation tissue formation. The pathogenesis of pressure ulcers showing granulation tissue may vary; however, no terminology has been defined to describe existing ulcers. Thus, we previously defined terminology for granulation tissue to describe individual ulcers. Based on these terms, we retrospectively evaluated the findings of deep pressure ulcers. In particular, we focused on polypoid granular tissue, a unique morphological feature. Polypoid granulation tissues were frequently observed in pressure ulcers over the sacrum compared with those over the foot. Chronological observation of a few cases indicated that external forces from specific directions during the healing process caused the development of polypoid granulation tissue. In addition, most pressure ulcers showing polypoid granulation tissue exhibited a trench-like appearance in individual wounds. Based on these observations, polypoid granulation tissue may generate from specific external forces, which lead to wound deformity. Morphological findings in an individual wound may be useful to predict the mechanical factors on existing pressure ulcers.
