Fig. 4. — Computed tomography (CT) images after BPA. BPA of an occluded left A10 posterior basal segment is performed using a workhorse wire and 2-mm-diameter balloon low-pressure inflation without angiographic evidence of vessel injury (a). Contrast chest CT images in coronal (b) and sagittal (c) views identify the source of vessel injury (arrows) associated with patient hemoptysis during overnight observation after BPA. Occult bleeding was considered to be due to wire-induced side branch injury in the context of mPAP 50 mmHg and PVR > 8 Wood Units.
