  • •S2V2PBGV,R,NT, S2V2PRGV,R,NT , S2V2PLGV,R,NT, with or without S2V2 PBIIV,R,NT, S2V2 PLIIV,R,NT, S2V2 PRIIV,R,NT
  • CT, TAUS and diagnostic venography (if needed) imaging review for pelvic venous imaging factors
  • Left or right ovarian vein diameter greater than or equal to 6 mm as documented by TAUS or CT
  • Presence of intrabdominal/pelvic varices as documented by TAUS or CT (≥1 veins, \>5 mm diameter)
  • Presence of venous reflux in ovarian and/or internal iliac veins without evidence of hemodynamically significant stenosis

Exclusion

  • Female \<18 years of age
