What is a common complication of untreated deep venous thrombosis?

• A. Peripheral artery disease
• B. Post-thrombotic syndrome
• C. Cerebral venous sinus thrombosis
• D. Arterial embolism

Answer: (B)

Post-thrombotic syndrome is a common complication of untreated deep venous thrombosis (DVT) due to the long-term effects that DVT can have on venous health. When a clot forms in a deep vein, particularly in the legs, it can lead to increased pressure in the venous system, resulting in damage to the valves within those veins. This damage can cause chronic symptoms such as leg swelling, pain, changes in skin color, and even venous ulcers. The risk of developing post-thrombotic syndrome is related to the severity of the initial clot and the duration it remains untreated. The other options represent complications or conditions that are less directly associated with untreated DVT. Peripheral artery disease, for instance, pertains to issues in the arteries, not veins. Cerebral venous sinus thrombosis occurs within the brain and is not a direct consequence of untreated DVT in peripheral veins. Similarly, arterial embolism refers to a blockage in the arterial system, often stemming from an embolus (which can originate from various sources but is not specifically a result of untreated DVT). Thus, none of these options encapsulate the chronic, venous complications that follow a DVT as accurately as post-thrombotic syndrome.
