Time (minutes)
Follow-up (time and patient status)
155FCT abdomen/pelvis (90 s contrast delay)1 monthIVC (Below Filter) OcclusionBilateral Femoral Vein OcclusionMetastatic ovarian carcinoma. IVC and iliac vein thromboses related to extrinsic compression and carcinoma-related hypercoagulability.YesNo4.21 year followup (no further visits), no recurrent occlusion, continued compression stockings
252MCT abdomen/pelvis (90 s contrast delay)3 monthsIVC (Below Filter) OcclusionCIV Confluence Occlusion; Bilateral CIV and EIV StenosisRLE provoked DVT in 2015 following lumbar spinal surgery. IVC filter placed. Course complicated by progression of thrombosis and post-thrombotic syndrome.YesYes, new occlusion below iliocaval confluence5.25 year followup, no recurrent ileocaval occlusion, continues daily Coumadin 2  mg for chronic scarring of bilateral femoroal-popliteal veins
362MMRI venogram abdomen/pelvis1 monthLeft CIV Stenosis, Left EIV OcclusionLeft Popliteal OcclusionUnprovoked LLE DVT in 2016. Subsequent post-thrombotic syndrome with femoral vein stenosis and occlusive popliteal vein stenosis.YesYes, progression of thrombosis to include left EIV (initially from CFV)3.02 year follow-up (no further visits), no recurrent iliac stenosis/occlusion. Persistent mid left femoral vein occlusion with post-thrombotic change, switched to Xarelto and Aspirin 81 mg daily
454MCT abdomen/pelvis (90 s contrast delay)4 monthsRight EIV to CFV Confluence In-Stent StenosisDistal Right CFV StenosisMorbidly obese patient with pulmonary hypertension, sarcoidosis, and IVC narrowing. Prior stenting from intrahepatic IVC to iliac bifurcation in 2015. Multiple subsequent venoplasties and stent extensions for lower extremity symptomatic control.NoaN/A, diagnosis could not be made on CT1.64 year followup, no further stenting, decreased frequency of interval venoplasties (yearly instead of every 3–6 months) for mild stenoses at junction of proximal IVC and right common femoral vein constructs, continues Coumadin 3 mg and Aspirin 81 mg daily
564FCT abdomen/pelvis (90 s contrast delay1 monthIVC (Below Filter) OcclusionBilateral EIV OcclusionMorbidly obese patient with history of breast carcinoma, positive lupus anticoagulant, and DVT/pulmonary embolism following gastric bypass in 2010 at outside hospital. IVC filter placed. Following transition of care to current institution, note made of progressed iliocaval thrombotic burden below filter with post-thrombotic syndrome.YesNo3.84 year followup, no recurrent occlusion, continuing daily Xarelto
636MCT abdomen/pelvis (90 s contrast delay)2 weeksLeft CIV In-Stent OcclusionLeft Femoral VeinHistory of Factor V Leiden, May Thurner Syndrome, and multiple prior LLE extremity interventions. Rethrombosis of indwelling stents within the left CIV, EIV, and CFV.YesNo2.43 year followup, recurrent occlusion 1 year following initial procedure, subsequent thrombolysis and thrombectomy with repeat occlusion 1 year following this, no further interventions given low likelihood of recanalization, continues daily Aspirin 81 mg and Fondaparinux
