A patient who was found to be pregnant unexpectedly during hysteromyomectomy

We present a case of an unexpected pregnancy and an ultimately successful obstetric outcome. The patient underwent abdominal myomectomy under spinal anaesthesia for a uterine leiomyoma with menorrhagia and infertility. Later, she was found to have been in the 7th gestational day at the time of surgery. The blastocyst survived the surgical manipulation and anaesthesia, resulting in a successful pregnancy. The literature on the endocrinological stress response during anaesthesia and surgery suggests that spinal anaesthesia administered in this case was potentially helpful in maintaining progesterone levels and avoiding increased prolactin levels; increased prolactin levels might be deleterious to implantation of the blastocyst.
