Pulmonary endarterectomy is a conventional definitive therapeutic strategy for the treatment of chronic thromboembolic pulmonary hypertension.1 Several reports recently demonstrated that balloon pulmonary angioplasty (BPA) improves clinical status and hemodynamics in patients with chronic thromboembolic pulmonary hypertension.2 Because the success of reperfusion of occluded pulmonary vessels is considered to depend on the patency of the distal vessels via the systemic collateral circulation, the assessment of regional pulmonary perfusion is important for the selection of the candidates when performing either BPA or pulmonary endarterectomy. Lung perfusion scintigraphy cannot provide information regarding lung perfusion via the systemic collateral circulation. Lung perfused blood volume computed tomography (PBV-CT) is useful for the assessment of lung perfusion in occluded areas during the pulmonary arterial phase and the systemic arterial phase.3A 73-year-old man was referred to …
