Abstract

Background. End-stage renal disease (ESRD) patients receiving chronic hemodialysis (HD) via an arteriovenous (A-V) access often develop unexplained pulmonary hypertension (PHT). This study evaluated the role of pulmonary calcification (PC) in this phenomenon. Methods. The clinical manifestations, systolic pulmonary artery pressure (PAP) values measured by Doppler echocardiography and the presence and the extent of PC expressed by lung uptake of 99mTc-MDP bone scintigraphy, were studied in 49 patients with ESRD receiving chronic HD therapy via A-V access. The correlation between PC and PHT was investigated. Results. There were 36 men and 13 women with a mean age of 61.7 ± 13.2 years receiving HD therapy for 38.2 ± 43.7 months. Twenty (40.8%) patients had PC expressed by increased lung uptake of 99mTc- MDP and 28 (57.1%) patients had PHT with a mean systolic PAP of 46 ± 11 mm Hg. No correlation was found between PC and PHT. Conclusion. The data suggest that PC expressed by lung uptake of 99mTc-MDP has no role in the pathogenesis of PHT among ESRD patients undergoing HD therapy via A-V access.
