Clinical course

Summary

• A patient was referred to us because of a severely infected ischemic wound.

• EVT was immediately conducted on admission day.

• After EVT, the infective ulcer wassubjected to debridement by a plastic surgeon in the intensive care unit.

• Additional amputation and skin transplantation were performed and limb salvage was achieved.

• Patient’s status is now ambulatory.
