Final answer:
A thrombus that blocks the popliteal vein would interfere with blood flow in several other veins, including the femoral vein, fibular vein, and anterior and posterior tibial veins. The deep femoral vein, great saphenous vein, and accessory saphenous vein can also experience reduced blood flow.
Step-by-step explanation:
A thrombus that blocks the popliteal vein can interfere with blood flow in several other veins.
Since popliteal vein receives blood from the femoral vein, fibular vein, and anterior and posterior tibial veins, a blockage in the popliteal vein would impede the blood flow in these veins as well.
Additionally, the deep femoral vein, great saphenous vein, and accessory saphenous vein can also experience reduced blood flow due to the blockage in the popliteal vein.
