Abstract:

The postoperation thrombosis after assisted reproductive technology (ART) may typically occur in precava vein and antrorse vein such as upper extremities vein and internal jugular vein, which is related mainly to the ovarian hyperstimulation syndrome (OHSS) following ART. We reporte a rare case of thrombosis in the portal vein and superior mesenteric vein after 3 weeks of the frozen-thawed embryo transfer (FET). The patient presented with the persistent subxiphoid pain without any obvious precipitating factors. Diagnostic evaluations, including abdominal color Doppler ultrasound, indicated the portal vein and superior mesenteric vein thrombosis. The pregnancy was terminated through suction curettage, following with anticoagulation and antiplatelet therapy. The patient was discharged after clinical improvement, and continued antiplatelet therapy. On six-month follow-up, the patient did not showed any thrombus recurrence. The patient did not develop OHSS, and the thrombus location was atypical. This retrospective analysis enhances our understanding of the complications following ART, such as the deep vein thrombosis.
