Method and system for assessing severity and stage of peripheral arterial disease and lower extremity wounds using angiosome mapping

摘要

The present invention provides a system for assessing the severity and stage of PAD including at least one sensor that measures skin perfusion pressure; a knowledge base that provides data on lower extremity angiosomes; and a processing device in operable communication with the sensor and the knowledge base, the processing device that outputs a visual representation of at least one of the lower extremity angiosomes that guides the sensor in the mapping of a testing site relative to a target vessel where the skin perfusion pressure measurement will be taken.

1. A system for assessing severity and stage of lower extremity disease comprising:
at least one sensor that measures peripheral vascular conditions of a patient; a knowledge base that provides data on a plurality of lower extremity angiosomes; a processing device in operable communication with said at least one sensor and said knowledge base, said processing device configured to (a) output a visual representation of at least one of said plurality of lower extremity angiosomes, said visual representation to guide the placement of said sensor in angiosome mapping of a testing site relative to a target vessel in an angiosome; (b) receive a peripheral vascular measurement based on said angiosome mapping; and (c) cross reference said peripheral vascular measurement with said knowledge base to generate a cross referenced data result indicative of a severity and stage of lower extremity disease, wherein said processing device outputs data that is indicative of said severity and stage of lower extremity disease based on said angiosome mapping based on said cross referenced data result.
