Current application of superb microvascular imaging in tibial transverse transport for diabetic foot

摘要:

胫骨横向骨搬移技术通过调节搬移骨块诱导糖尿病足足部微血管的再生，进而促进溃疡愈合，保存肢体。为明确搬移过程中足部微循环变化情况，临床常用超声进行监测。然而常规超声对于观察糖尿病足足部末梢微小血管的变化作用有限， 无法发现肢体末梢微小血管的血流灌注情况。超微血流成像技术是一种新型的无创血流成像技术，与常规超声相比，该技术可敏感捕捉低速血流，在微血管病变、微血流灌注等方面具有相对优势。本文主要对超微血流成像在糖尿病足胫骨搬移中的应用现状进行综述。

Abstract:

The tibial transverse transport technique can induce the microvascular regeneration of diabetic foot by regulating the trans- ported bone fragments to promote ulcer healing and preserve limbs. In order to clarify the changes of foot microcirculation during transport, ultrasound is often used for monitoring in clinic. However, conventional ultrasound is often limited in observing the changes of the distal mi- crovessels of the whole part of diabetes foot and cannot detect the blood perfusion of microvessels in the distal extremity. The superb micro- vascular imaging is a new non-invasive blood flow imaging technology. Compared with conventional ultrasound technology, clinical studies have found that superb microvascular imaging can sensitively capture low-velocity blood flow, and has relative advantages in terms of micro- vascular disease, and micro-blood perfusion. This paper reviews the application status of superb microvascular imaging in the treatment of diabetic foot by tibial transverse transport.
