combined use of vacuum assisted suction and heat exchanger warming
expectant medical management
The novel idea that this study proposes, is the combined use of vacuum assisted suction and heat exchanger warming. It is well known that heat causes capillary vasodilation, where warming hands and toes improves blood flow while cooling them causes vasoconstriction. Applying a vacuum across a capillary bed increases the transcapillary gradient increasing the driving force of blood flow into tissues. The combination of these two mechanisms can work synchronously to improve blood flow to ischemic extremities and digits.
expectant medical management will continue to the contralateral hand
