脉管炎的临床表现-III期(组织坏死期)

来源:华人健康网 | 发布时间:2010-10-30 10:49:19 | www.chinesejk.com

III期(组织坏死期)

除上述症状继续加重外,患肢严重缺血,静息痛更为加重,疼痛剧烈,经久不息,患者日夜屈膝抱足而坐,稳夜不眠。食量减小,体力日衰,明显消瘦。若并发局部感染,可出现发烧、畏寒、烦躁等全身毒血症状。肢端组织缺血更为严重,产生溃疡或坏疽。大多为干性坏疽,趾(指)端干枯发黑,可向近端延伸。坏死组织脱落后,形成经久不愈的溃疡。若继发感染,则呈湿性坏疽。根据坏疽的范围,可分为三级:Ⅰ级,坏疽局限于趾(指)部;Ⅱ级,坏疽延及趾蹠(指掌)关节及蹠(掌)部;Ⅲ级,坏疽延及足跟、踝关节或踝关节以上。
