Bronchoscopic view of a cryoprobe showing "back-freezing"
This image is representative of a bronchoscopic cryoprobe targeting an endobronchial lesion (seen anteriorly). The metal tip (arrow) is in clear view protruding from the end of the bronchoscope. Noteworthy, is the snow-like appearance on the outside of the probe ("back-freezing" effect). Damage to the bronchoscope can be avoided by keeping the probe tip in clear view beyond the tip of the bronchoscope.
