Gas gangrene is not a frequently encountered toxic wound infection in child
hood. We present a case of postoperative Clostridium perfringens infection
with proximal forearm myonecrosis. In order to reveal the full extent of ti
ssue viability in the right upper extremity, infrared thermography was perf
ormed. Although dyschromia was evident in the proximal forearm, thermograph
s revealed viable tissue only up to the supracondylar region. Angiography,
which provided valuable clues to the patency of the vascular supply, and su
bsequent intraoperative findings confirmed the extent of tissue perfusion a
s revealed by infrared thermography.
