Abstract
BACKGROUND:
Agenesis of the inferior vena cava (IVC) is an uncommon congenital vascular malformation. We report a case in a teenage female recently started on oral contraception.
CASE:
Because of menorrhagia, the patient had begun an oral contraceptive pill (OCP) 1(1/2) months prior to presentation. She initially presented with pelvic and lower back pain, and imaging showed a pelvic deep venous thrombosis (DVT) and an interrupted IVC. Anticoagulation was started, the OCP was discontinued, and a discussion occurred regarding the treatment options for her menorrhagia following her recent diagnosis.
SUMMARY AND CONCLUSION:
The case presented shows the rare occurrence of the congenital absence of an IVC with pelvic thrombosis in a young female with a history of menorrhagia and new onset of pelvic pain. The evaluation of this case report leads to a comprehensive review in the treatment choice for menorrhagia with the preceding history of a thrombotic event.
