AB  - The  superior  vena  cava  (SVC)  is  formed  by  the  confluence  of  the  right  and  left  innominate  veins  and  enters  the  right  atrium  at  its  upper  pole.  The  SVC  lies  along  the  right  sternal  border.  The  right  innominate  vein  lies  more  vertical  and  is  shorter  then  the  left  innominate  vein.  The  SVC  is  about  7  cm  long.  This  vein  is  valveless  and  is  joined  by  the  azygous  vein  entering  the  SVC  posteriorly.1  Early  in  development,  two  paired  anterior  cardinal  veins  form  the  primitive  venous  return  as  the  left  anterior  vein  involutes  and  contributes  to  the  left  brachiocephalic  vein.  The  junction  of  the  primitive  left  anterior  cardinal  vein  (LACV)  and  the  right  anterior  cardinal  vein  thus  forms  the  SVC.  The  primitive  cardinal  veins  coalesce  to  the  atrium  via  the  sinus  venosus.  The  sinus  venosus  then  becomes  the  coronary  sinus  (Figure  19-1).
