ABSTRACT: To present two cases of myomectomy complicated by intravascular hemolysis leading to acute renal failure and discuss the differential diagnosis and possible mechanism.
Minimally Invasive Therapy Unit, University Department of Obstetrics and Gynecology.
Two premenopausal patients with uterine fibroids.
Both patients underwent otherwise uncomplicated myomectomies, one by laparotomy and one by laparoscopy, with tourniquets around the uterine and ovarian vessels being used to control intraoperative bleeding.
Renal function in the postoperative period.
Both patients developed a very rare complication after surgery of severe thrombocytopenia with microangiopathic hemolytic anemia leading to acute renal failure. One patient made a full recovery within weeks but the other still has reduced renal function almost 2 years after the surgery. The differential diagnosis consisted of disseminated intravascular coagulation or hemolytic uremic syndrome.
The etiology of thrombotic microangiopathy in these patients was unclear, but disruption and manipulation of fibroids during surgery may have led to the dissemination of pro-coagulant tissue factor containing particles leading to disseminated intravascular coagulation or hemolytic uremic syndrome, perhaps aggravated by utero-ovarian ischemia caused by the tourniquets.
