Figure 4From: Hybrid repair of an aortocaval fistula and inferior vena cava external compression caused by an inflammatory aortoiliac aneurysm: a case studyVenographic imaging. a) Venography from the right femoral vein immediately after stent graft insertion. The contrast agent has filled the excluded aneurysmal sac. The IVC is visualized but compression is still present. b) Venography from the right femoral vein immediately after stent graft insertion. The left CIV is visualized; however, it is occluded. c) Bilateral femoral vein angiogram after kissing technique stent insertion. Severe stenosis in the IVC has improved, and caval venous flow has recovered after insertion of bare metallic stents. Minimal contrast agent filling of the aneurysmal sac is observed.Back to article page
