请各位大侠帮忙翻译一句话（长难句）
Control of these wounds is by surgical excision often down to fascia as the delay has ensured that the zone of stasis has converted second-degree burns to full thickness.

答案

由于治疗延误已经导致瘀滞区由二度烧伤转至全层,所以通常通过向下到筋膜的切除手术来控制这些伤口.
（Control of these wounds）（主语）（ is by ）（谓语）（surgical excision）（宾语）（ often down to fascia）（定语,修饰surgical excision） as （后面是as引导的原因状语从句）the delay has ensured that（从句中又含that引导的宾语从句） the zone of stasis has converted second-degree burns to full thickness.
