Venous star
The venous star is a connection between several epifascial veins of the lower extremity that is formed before the confluence with the saphenous hiatus .
In the venous star, the superficial (epifascial) leg veins of the lower extremity unite with the deep, ultimately draining femoral vein . In addition to the great saphenous vein , three to ten epifascial veins flow from the area of the thigh and the external genitalia. In the saphenous hiatus, the veins flow together into the femoral vein. At the point of confluence, the fascia lata is looser and more permeable as the fascia cribrosa .
Possible veins include:
- Great saphenous vein
- Venae pudendae externae (inflow from the genital area)
- Vena pudenda profunda
- Vena epigastrica superficialis (part of the portocaval collateral circulation )
- Vena circumflexa ilium superficialis (catchment area is the skin below the ligamentum inguinale )
- Lateral accessory saphenous vein (inconsistent lateral branch of the great saphenous vein)
- Medial accessory saphenous vein .
