angiosome理念在重症下肢缺血膝下病变血运重建中的意义

angiosome是一个解剖单元，包括皮肤、皮下组织、筋膜、肌肉、骨骼以及供应其血液的源动脉和特定的引流静脉。按照angiosome理念，不管是采取腔内还是外科旁路手术，重建膝下动脉病变的源动脉血运对重症肢体缺血患者可能产生更好的伤口愈合率及更高的保肢率。笔者就angiosome理念及其在下肢重症缺血膝下血管病变血运重建治疗策略制定方面的作用作一综述。

Angiosome concept in revascularization of critical limb ischemia with below-the-knee disease

Angiosome is an anatomic unit of tissue, which is consisted of skin, subcutaneous tissue, fascia, muscle and bone, as well as the source artery for its blood supply and its specific drainage veins. According to the angiosome concept, revascularization of the source artery of the below-the-knee (BTK) lesion might result in better wound healing and limb salvage rate in patients with critical limb ischemia (CLI) undergoing either bypass or endovascular operation. In this paper, the authors address the angiosome concept and its role in revascularization strategy making for CLI patients with BTK disease.
