Pulmonary Veno-Occlusive Disease

Pulmonary veno-occlusive disease is a rare disorder in which the small veins of the lungs narrow or become obstructed, making it harder for blood to pass through and increasing the pressure within the pulmonary circulation.

Common symptoms: It may present with progressive shortness of breath, fatigue, a feeling of faintness with exertion, and, at times, cough. Symptoms tend to worsen with physical activity.

When to see a doctor? It is advisable to seek care if difficulty breathing worsens or if dizziness appears during exertion.

Which specialist evaluates it? Because it affects the pulmonary circulation, it usually requires the involvement of professionals experienced in blood vessels and lung diseases, such as the vascular specialist. If shortness of breath worsens without explanation, a timely evaluation helps guide the workup.
