Successful surgical treatment of a giant uterine leiomyoma: A case report.

INTRODUCTION AND IMPORTANCE

Uterine leiomyoma is a common disease. The tumor gradually increases and becomes a target for treatment when accompanied by certain symptoms. It rarely grows into a giant uterine leiomyoma, which is defined as leiomyoma weighing >11.34 kg.

CASE PRESENTATION

A 58-year-old Japanese woman had a history of putamen hemorrhage and deep vein thrombosis. A giant uterine leiomyoma prevented her from walking, and she scheduled surgery for its removal. The tumor was 46 × 35 × 27 cm, and the uterine arteries and veins were extremely dilated. A blocking balloon catheter was placed in the abdominal aorta to prevent massive bleeding, and a filter was placed in the inferior vena cava to prevent pulmonary thromboembolism. The surgery focused on careful vascular treatment, with selective ligation of the ovarian arteries and veins and the uterine arteries. The total amount of bleeding was 1130 g, and the uterus was removed without complications. The weight of the excised tissue was 22.6 kg.

CLINICAL DISCUSSION

Surgical treatment of the largest giant uterine leiomyomas is rare and challenging. Previous reports addressed the risk of massive bleeding and perioperative death. Surgery is the best treatment for giant uterine leiomyomas, but perioperative management and surgical procedures require complex and elaborate planning.

CONCLUSION

Very few gynecologists have experience treating giant uterine leiomyomas. Successful surgery requires careful surgical preparation, and the gynecological oncologist must have extensive experience with giant leiomyomas.
