Post-thrombotic syndrome (PTS) is a complication that may occur after someone has suffered from a DVT. Veins have valves that control the direction of blood flow and PTS occurs when these valves are damaged by the clot.
Chronic thromboembolic pulmonary hypertension (CTEPH) is an increase in pressure in the pulmonary arteries, which carry blood from the heart to the lungs. It is caused by a clot increasing resistance to the blood flow.
