Descriptive data reveals effects of treatment duration and nerve block on therapeutic temperature success during cryoneurolysis.
During percutaneous cryoneurolysis, the temperature of tissue is frequently deceptively warm relative to the returning gas and tissue frequently does not reach an adequately cold temperature; prolonging gas treatment from 3 to 5 min improves the success of reaching therapeutic temperatures; the presence of a peripheral nerve block appears to lessen the chance of reaching therapeutic temperatures; and caution is warranted when treating consecutive intercostal nerves as tissue temperature may decrease with each level.
