工作背景：完整皮肤下深部组织损伤的概念有助于我们了解压疮的发病机制，但最好的方法检测和评估深部组织injure.Methods：中频（10 MHz）超声进行评估深部组织损伤。作者分析了12例患者（9例男性患者和3例女性患者，年龄16至92岁）谁表现出深层组织损伤相关的异常超声检查结果在第一次检查，并进行了随访，直到压力性溃疡达到了最后stage.Results：在12例溃疡的阶段恶化与基线相比，在其余6例愈合。作者将深部组织损伤的超声异常征象分为四种类型：分层结构不清、低回声病变、筋膜不连续和不均匀低回声区。第一次检查发现分层结构不清、低回声病变、不连续筋膜和不均匀低回声区分别为12、10、7和5例。深部组织损伤的压疮以分层结构不清和低回声区多见，但随访结果提示筋膜不连续和不均匀低回声区是预测压疮进展的可靠指标。结论：中频超声的使用可靠地识别了深部组织损伤，并被认为有助于预防和治疗压力-相关的溃疡结果表明，特定的超声特征可以预测压疮的进展。（Plast。重建124：540，2009）。
Background: The concept of deep tissue injury under intact skin helps us understand the pathogenesis of pressure ulcers, but the best method for detecting and evaluating deep tissue injury remains to be established.Methods: Intermediate-frequency (10-MHz) ultrasonography was performed to evaluate deep tissue injury. The authors analyzed 12 patients (nine male patients and three female patients aged 16 to 92 years) who showed deep tissue injury-related abnormal findings on ultrasonography at the first examination and were followed up until the pressure ulcer reached a final stage.Results: The stage of ulcer worsened in six of 12 cases compared with baseline, and healed in the remaining six patients. The authors recognized four types of abnormal signs unique to deep tissue damage in ultrasonography: unclear layered structure, hypoechoic lesion, discontinuous fascia, and heterogeneous hypoechoic area. Unclear layered structure, hypoechoic lesion, discontinuous fascia, and heterogeneous hypoechoic area were detected at the first examination in 12, 10, seven, and five patients, respectively. Unclear layered structure and hypoechoic lesion were more commonly seen in pressure ulcers in deep tissue injury than the other features, but the follow-up study suggested that discontinuous fascia and heterogeneous hypoechoic area are more reliable predictors of future progression of pressure ulcers.Conclusions: The use of intermediate-frequency ultrasound reliably identified deep tissue injury and was believed to contribute to prevention and treatment of pressure-related ulcers. The results suggest that specific ultrasonographic characteristics may predict which pressure ulcers will progress. (Plast. Reconstr. Surg. 124: 540, 2009.)
