What vein does a thrombus in a soleal vein typically propagate to next?

A thrombus in a soleal vein typically propagates to the posterior tibial veins. The soleal veins are deep veins located in the calf and are often interconnected with the posterior tibial veins, thus providing a direct pathway for the thrombus to travel upward. When a thrombus develops in the soleal veins, it can easily extend into the larger posterior tibial veins, contributing to the risk of deeper venous thrombosis. Understanding the anatomical relationships between these veins is essential in assessing the risk and management of venous thromboembolism. The other veins listed may be related anatomically to some extent, but the direct propagation route from the soleal veins primarily leads to the posterior tibial veins due to their close proximity and connection.
