One complication of deep venous recanalization is:

• A. damage to venous valves, allowing reflux
• B. embolization of thrombus
• C. less prominent superficial veins
• D. pain in the area of thrombus

Answer: (A)

The correct answer is damage to venous valves, allowing reflux. In deep venous recanalization, a procedure often performed to restore blood flow through obstructed veins, there is a risk of causing injury to the venous valves. These valves are crucial for preventing blood from flowing backward (reflux) in the venous system. If the valves are compromised during the recanalization process, it can lead to insufficient closure of the valves when blood flows, resulting in venous reflux. Chronic venous insufficiency and varicosities may develop as a consequence of this damage, leading to long-term complications. The other options, while they may also be associated with complications in various medical procedures, do not directly relate to the specific risks posed by deep venous recanalization in the context of venous valve integrity. For example, embolization of thrombus would be a concern during procedures that involve manipulating or dislodging clots, but damage to venous valves specifically pertains to the operation's impact on venous function.
