Posterior tibial veins
Venae tibiales posteriores
- Origin
- Formed behind the medial malleolus by the confluence of the medial and lateral plantar veins
- Insertion
- Ascend as paired venae comitantes alongside the posterior tibial artery to join the fibular and anterior tibial veins in forming the popliteal vein
- Function
- Major deep venous return channels for the calf and sole; receive Cockett's perforating veins
- Innervation
- Sympathetic vasomotor fibers
- Movement & chain
- Equipped with multiple pairs of valves preventing gravitational venous reflux
- Palpation
- Not palpable beneath the flexor retinaculum
- Clinical
- Most common site of isolated distal deep vein thrombosis (DVT); deep venous reflux causes medial gaiter stasis ulceration
- Segmental innervation
- Posterior leg deep venous network
- In clinical practice
- Routinely assessed on compression Doppler ultrasound for distal DVT; treated with anticoagulation and graduated compression
