# | Age | Gender | Preprocedural Imaging | Time between Imaging and Procedure | Proximal Extent | Distal Extent | Pathology | Occlusive | Change between Imaging and Procedure? | Crossing Time (minutes) | Follow-up (time and patient status) |
---|---|---|---|---|---|---|---|---|---|---|---|
1 | 55 | F | CT abdomen/pelvis (90 s contrast delay) | 1 month | IVC (Below Filter) Occlusion | Bilateral Femoral Vein Occlusion | Metastatic ovarian carcinoma. IVC and iliac vein thromboses related to extrinsic compression and carcinoma-related hypercoagulability. | Yes | No | 4.2 | 1 year followup (no further visits), no recurrent occlusion, continued compression stockings |
2 | 52 | M | CT abdomen/pelvis (90 s contrast delay) | 3 months | IVC (Below Filter) Occlusion | CIV Confluence Occlusion; Bilateral CIV and EIV Stenosis | RLE provoked DVT in 2015 following lumbar spinal surgery. IVC filter placed. Course complicated by progression of thrombosis and post-thrombotic syndrome. | Yes | Yes, new occlusion below iliocaval confluence | 5.2 | 5 year followup, no recurrent ileocaval occlusion, continues daily Coumadin 2 mg for chronic scarring of bilateral femoroal-popliteal veins |
3 | 62 | M | MRI venogram abdomen/pelvis | 1 month | Left CIV Stenosis, Left EIV Occlusion | Left Popliteal Occlusion | Unprovoked LLE DVT in 2016. Subsequent post-thrombotic syndrome with femoral vein stenosis and occlusive popliteal vein stenosis. | Yes | Yes, progression of thrombosis to include left EIV (initially from CFV) | 3.0 | 2 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 |
4 | 54 | M | CT abdomen/pelvis (90 s contrast delay) | 4 months | Right EIV to CFV Confluence In-Stent Stenosis | Distal Right CFV Stenosis | Morbidly 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. | Noa | N/A, diagnosis could not be made on CT | 1.6 | 4 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 |
5 | 64 | F | CT abdomen/pelvis (90 s contrast delay | 1 month | IVC (Below Filter) Occlusion | Bilateral EIV Occlusion | Morbidly 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. | Yes | No | 3.8 | 4 year followup, no recurrent occlusion, continuing daily Xarelto |
6 | 36 | M | CT abdomen/pelvis (90 s contrast delay) | 2 weeks | Left CIV In-Stent Occlusion | Left Femoral Vein | History of Factor V Leiden, May Thurner Syndrome, and multiple prior LLE extremity interventions. Rethrombosis of indwelling stents within the left CIV, EIV, and CFV. | Yes | No | 2.4 | 3 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 |
