Diagnostic Code 7121 · 38 CFR §4.104
Post-phlebitic syndrome (also called post-thrombotic syndrome) is a long-term complication that develops after a deep vein thrombosis (DVT). After a blood clot damages the valves inside a vein, blood can no longer flow efficiently back to the heart, causing chronic pooling in the affected leg. This results in persistent swelling, pain, skin discoloration, and in severe cases skin breakdown and ulceration. Veterans who had a DVT during or related to military service can develop this chronic condition months or years later.
