Late-Onset Ovarian Bleeding After Transvaginal Oocyte Retrieval in a Patient With Suspected Hereditary Hemorrhagic Telangiectasia

Assisted reproductive technology (ART) requires transvaginal oocyte retrieval (TVOR), and ovarian bleeding after TVOR rarely occurs. We present a case of a 37-year-old woman (0-gravida) who was diagnosed with possible hemorrhagic telangiectasia (HHT) and had a history of three laparotomies for ovarian bleeding and an inclusion cyst adjacent to the right ovary after the third operation. HHT is a hereditary disease characterized by spontaneous hemorrhage of some organs, such as the nose, brain, lungs, gastrointestinal tract, and liver. She desired ART after fertility treatment and then had abdominal pain with ovarian swelling five days after TVOR. Moreover, both the right ovary and inclusion cyst were gradually swollen with hematoma. Finally, abdominal pain and the hemoglobin level deteriorated, necessitating an emergency surgery on the eighth day. We notify reproductive physicians that patients with HHT may readily develop ovarian bleeding with or without inclusion cysts after TVOR, although inclusion cysts may also be associated with late-onset bleeding.
