Abstract
A case of twin pregnancy associated with HELLP syndrome is reported. The case is unique in that the patient lacked the usual symptoms and signs of hypertension, abdominal right upper quadrant pain, and tenderness. A 26-year-old primiparous woman developed preeclampsia during late pregnancy, antithrombin III activity is more likely to decrease in women with twin pregnancies. After giving birth, blood tests suggested that she had developed the HELLP syndrome (decreased platelet count, impaired liver function). The causes of HELLP syndrome were many and varied, with a large proportion having no obvious cause, the monitoring of AT-III activity and platelet count in women who exhibit a gradual decline in these parameters may help to avoid the development of severe HELLP syndrome.
