Patients receiving hemodialysis (HD) need to avoid skin laceration; amputation is common because of intractability of wounds and complications with other diseases, including diabetes mellitus. We have reported the usefulness of aggressive debridement deep enough to expose bone marrow cells, occlusive dressing, and epidermal grafting for diabetic foot ulcers and wounds from rheumatic diseases.
To test whether this experimental protocol is effective to treat intractable wounds in a patient receiving HD accompanied with arteriosclerosis obliterans (ASO).
A 78-year-old patient with chronic renal failure and arteriosclerosis obliterans suffered a wound with exposed bone on the left great toe. Aggressive combination therapy was effective despite methicillin-resistant Staphylococcus aureus infection, and the wound healed in 13 weeks.
This study, reporting a single case, limits the interpretation of results.
Aggressive debridement exposing bone marrow cells is useful in preparing a healthy wound bed and epidermal sheet grafting may be accepted more advantageously in an ischemic environment and adopt a site-specific phenotype via mesenchymal-epithelial interactions.
接受血液透析(HD)的患者需要避免皮肤撕裂;由于伤口难愈以及包括糖尿病在内的其他疾病引发的并发症,截肢情况很常见。我们已经报道了积极清创至足够深以暴露骨髓细胞、封闭敷料以及表皮移植治疗糖尿病足溃疡和风湿性疾病伤口的有效性。
测试该实验方案对治疗伴有动脉硬化闭塞症(ASO)的HD患者的难愈伤口是否有效。
一名78岁患有慢性肾衰竭和动脉硬化闭塞症的患者左大脚趾出现伤口并暴露骨头。尽管存在耐甲氧西林金黄色葡萄球菌感染,积极的联合治疗仍有效,伤口在13周内愈合。
本研究报告的是单个病例,限制了结果的解释。
暴露骨髓细胞的积极清创有助于准备健康的伤口床,表皮片移植在缺血环境中可能更具优势,并可通过间充质 - 上皮相互作用呈现位点特异性表型。
