ObjectivesDetermination of resection margins is very important in anatomical lung resections for both oncologic outcomes and postoperative complications. Absence of intersegmental plans naturally in segmentectomy surgeries and presence of incomplete fissure variationally in pulmonary lobectomy procedures constitute a challenge for surgeons in determining resection margins. Thoracic surgeons can prefer various techniques such as inflation deflation method, indocyanine green imaging, and three-dimensional segment modeling to cope with this problem. These techniques have some disadvantages such as high cost, the necessity of intravenous drug administration, need for an additional imaging system and ineffectiveness due to emphysema, anthracotic lung surface or interalveolar pores. Here we studied an alternative method for the solution of these disadvantages and aimed to demonstrate the correctness of a hypothesis based on detecting the cooling of the ischemic lung portion by a thermal camera after dividing the related pulmonary artery.MethodsWe planned determining margins of resection with a thermal camera in patients scheduled for pulmonary lobectomy or segmentectomy. We made some measurements and mapping with a thermal camera before and after the dividing of pulmonary artery of related lobe or segment then processed the images taken with a software on the computer.ResultsWe detected a significant decrease in temperature in the ischemic lung area and demonstrated mapping the demarcation line between ischemic and perfused areas effectively by thermography in a total of 32 patients underwent lung resection.ConclusionPulmonary resection margins can be detected effectively by thermography in patients.
