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

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

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
