Abstract

Portal vein thrombosis complicating pregnancy is a rare occurrence. The etiology of portal vein thrombosis is highly diverse. A 31-year-old multigravida was diagnosed with acute portal vein thrombosis at 12 weeks of gestation by ultrasound examination. She had epigastric and left upper quadrant pain, but there was no significant medical or surgical illness in the past. Laboratory studies showed no evidence of a thrombophilia. She was managed with anticoagulants and labor was induced at 38 weeks because of premature rupture of membranes. She delivered a healthy neonate without any complications. It seems that the cause of this thrombotic event was the hypercoagulable state of pregnancy.
