title: Endobronchial hemorrhage after intubation with double-lumen endotracheal tube in a patient with idiopathic thrombocytopenic purpura for minimally invasive cardiac surgery: a case report.
abstract: Minimally invasive cardiac surgery (MICS) requires lung isolation. Lung isolation is usually achieved with double-lumen endotracheal tube (DLT). Patients with idiopathic thrombocytopenic purpura (ITP) have an increased risk of bleeding events. We suspected endobronchial hemorrhage after exchange of DLT during induction of anesthesia for replacement of mitral valve in a 62-year-old man with a known ITP. The MICS was stopped and bronchial artery embolization was performed in the angiographic room. In the present case, in order to reduce the risk of bronchial arterial injury in ITP patient we intubated with single lumen endotracheal tube. Lung isolation led to achievement of intermittent total lung deflation. Based on the results, we recommend a high-dose intravenous immunoglobulin therapy and platelet transfusion prior to cardiac surgery in patients with ITP to increase platelet count. Moreover, it is proposed that in order to clear the vision during the operation, ventilation can be held or made intermittent both prior to cardiopulmonary bypass or at its conclusion to permit exposure.
