case_images: (a) A smooth-surfaced erythematous tumor was found on bronchoscopy, and (b) endobronchial resection of the bronchial carcinoid tumor was performed through bronchoscopy. (c) Preoperative angiography of the pulmonary artery confirmed central-type chronic thromboembolic pulmonary hypertension with a poorly perfused right lower segment. (d) Angiography before discharge showing improved perfusion of the pulmonary arteries. (e) Specimens removed from the pulmonary arteries during pulmonary endarterectomy.

case_images: Angiography of the pulmonary artery (PA) confirmed central-type CTEPH without apparent recent progression (Figure 1c). The bronchoscopic examination revealed a smooth-surfaced erythematous tumor at the right B9 + 10 entrance, completely obstructing the bronchus (Figure 1a). Resection of the tumor through the bronchoscope was performed concurrently, achieving bronchial patency without massive bleeding (Figure 1b). One week after endobronchial resection, when no occurrence of airway hemorrhage on resumed anticoagulation therapy with a heparin drip was confirmed, PEA was performed for all affected PA segments under deep hypothermic circulatory arrest (Figure 1e). Follow-up contrast-enhanced computed tomography and PA angiography showed improved perfusion of the PA (Figure 1d).
