50- year- old female patient with past medical history of mild intermittent asthma and hyper-tension presented with complaints of right leg swelling progressively worsening for a week . Lower extremity venous Doppler showed no evidence of deep vein thrombosis (DVT) in the femoral-popliteal systems bilaterally; however loss of respiratory variation in the wave-forms was seen in the right leg, raising the suspicion of possible DVT in the right external iliac or common iliac vein. Patient underwent CT venogram of the abdomen and pelvis with lower extremity run off. Results showed evidence of DVT in the right external iliac vein. Workup for various hypercoagulable states has been negative and she was started on anticoagulation for DVT with placement of retrievable IVC filter.
Plan: Patient is currently scheduled for endovascular treatment of DVT.
