Pulmonary Hypertension and Acute Heart Failure Following Lumbar Disc Surgery

Abstract

A 70-year-old woman was admitted with heart failure and signs of pulmonary hypertension on echocardiogram. Cardiac catheterization demonstrated postcapillary pulmonary hypertension, elevated cardiac output, and O₂ saturation enrichment. Computed tomography revealed a large arteriovenous fistula between the common iliac artery and vein, which was due to a lumbar disc surgery performed several years prior.
