Precautionary strategy for high‐risk airway bleeding cases during robotic‐assisted bronchoscopy

Bronchoscopy in thrombocytopenic patients remains a controversial topic as traditionally varying platelet thresholds have been stablished as “safe,” ranging from 20,000 to 50,000. A lower threshold may be safe for a routine airway inspection with bronchoalveolar lavage but will be far from safe for more invasive interventions such as needle biopsy, transbronchial biopsy, or cryo‐biopsy. Currently, a minimal platelet threshold during robotic‐assisted bronchoscopy (RAB) has not been established. In addition, the absolute platelet number does not guarantee appropriate platelet function. The literature regarding the safety of bronchoscopy and its bleeding risk, considering broader and more functional tests such as thromboelastography (TEG), is also lacking. We present our RAB approach to safely sample lung nodules in a patient with thrombocytopenia. Our precautionary strategy for high‐risk bleeding cases during RAB utilizing TEG and parallel flexible bronchoscopy with segmental balloon occlusion may be an appropriate technique to minimize bleeding risk.
