Spinal subarachnoid hematoma following spinal anesthesia in a patient with HELLP syndrome.

A case of subarachnoid hematoma following spinal anesthesia for cesarean section in a patient with HELLP syndrome is reported. A 39-year-old woman underwent cesarean section under spinal anesthesia for worsening preeclampsia with HELLP syndrome. Despite full recovery from the spinal anesthetic, on the second postoperative day she felt numbness on the posterior aspect of her right leg, noticed she was insensitive to bladder fullness and had mild flaccid paraparesis. Magnetic resonance imaging revealed a spinal subarachnoid hematoma with cauda equina compression. With conservative management she made an almost complete recovery within three months. Serial magnetic resonance imaging showed spontaneous regression of the hematoma. The risk of spinal subarachnoid hematoma following obstetric regional anesthesia is exceedingly small even in a patient with coagulopathy and, to our knowledge, this is only the second reported case following obstetric regional anesthesia. Anesthesia for HELLP syndrome in patients with an adequate platelet count but without disseminated intravascular coagulation is controversial. It is therefore important for clinicians to recognize the symptoms and signs of spinal subarachnoid hematoma to avoid delay in treatment that might result in severe neurological deficit.
