VAL-MAP for precise thoracoscopic sublobar lung resection

Virtual Assisted Lung Mapping(VAL-MAP) Although pre-operative CT-guided needle-mediated percutaneous marking techniques have been commonly used to identify and resect small lung nodules, major complications have been reported including bleeding, pneumothorax, and potentially fatal air embolism that may lead to myocardial infarction or cerebral infarction. CT-guided percutaneous marking techniques are also limited by the approachable locations (eg., lung apex, lung portions facing the mediastinum or the diaphragm, and interlobar fissure). As an alternative, the author (Sato M) developed Virtual Assisted Lung Mapping (VAL-MAP) in 2012 in Kyoto University. In this technique, we use virtual bronchoscopy that is developed from high-resolution CT as a guide of actual bronchoscopy and spray small amount of blue dye (indigo […]
