Document Summary

Blow to muscle e. g. calf, muscle bleeds, intracompartmental pressure rises, neurovascular bundle compressed, foot drop - need to decompress by fasciotomy before permanent damage occurs. Deep veins accompany arteries as venae comitantes below the knee. Veins drain from medial and lateral aspect of dorsal venous arch. Lateral aspect drained by short/lesser saphenous vein: behind lateral malleolus > superficial tissue over calf > penetrates deep fascia to enter popliteal fossa > popliteal vein. Perforating veins pierce deep fascia to join superficial and deep veins (esp great saph) Normally calf muscles pump blood up, sucking blood out of superficial veins. Incompetent valves (esp at termination of gsv, ssv and in perforating veins): blood pushed. Lymphatics following great saph go to inguinal nodes. Lymphatics accompanying short saph from heel/lateral foot/posterior leg drain into popliteal lymph nodes - tumour causes enlarged lymph node in back of knee.
