Ultrasound guided fine needle aspiration of ovarian cysts: diagnosis and treatment in pregnant and non-pregnant women.

Ovarian cysts are conventionally managed by laparoscopy or laparotomy. Twenty-two patients underwent fine needle aspiration of ovarian cysts under ultrasound control. Four patients were pregnant, and in two of these, aspiration of the cyst was performed transvaginally. The aspirate was examined cytologically and correlated with histology where available. The technique and results are discussed. No complications occurred. It is concluded that fine needle aspiration under ultrasound guidance is simple, safe and useful in the management of ultrasonically benign unilocular ovarian cysts in pre-menopausal women. It is of particular use in pregnancy, and in patients unsuitable for laparoscopy or surgery. Surgery can be reserved for cysts which recur after aspiration, cysts with a haemorrhagic aspirate, cysts in post-menopausal women and those with ultrasonic criteria of malignancy.
