Unusual case of pulmonary hypertension.

Truly reversible pulmonary hypertension is rare. Acquired systemic arteriovenous (A-V) fistulas following spinal surgery (laminectomy) are a less recognized cause of secondary pulmonary hypertension. We describe a patient who presented with symptoms and clinical evidence of pulmonary hypertension and underwent endovascular correction of an acquired A-V fistula, which led to improvement according to clinical and noninvasive hemodynamic criteria.
