OBJECTIVES We evaluated the reperfusion by balloon pulmonary angioplasty (BPA) in lung PBV and SPECT images. METHODS In total, 17 patients and 57 sessions were evaluated. Pre-BPA and post-BPA lung PBV and SPECT/CT images, based on both anatomical segments and physiologic regions (upper/middle/lower) were compared. RESULTS BPA had a positive effect on most hypoperfused/unperfused segments/regions. There was generally a high rate of agreement between PBV measurements and SPECT/CT. CONCLUSIONS BPA shows promise as a treatment modality for CTEPH patients. SPECT/CT, and, to a lesser extent, PBV, were useful in indicating areas in need of balloon angioplasty.
