Case Demonstration:
There is a large superior mediastinal mass caused by lung cancer
Chest Xray before stenting

Lung CA with Large superior mediastinal mass
causing obstruction of the SVC and swelling of the face. |
Chest Xray after stenting

Wallstent in place restoring flow to SVC
facial swelling symptoms resolved imediately |
First, a Diagnostic Venogram was performed by injecting iodinated contrast into the right antecubital vein in the arm and observing with the flouroscope the venous return to the SVC.
Here are the images of the venogram showing SVC obstruction:
 Right axillary vein opacified and looks good |
 Obstructed svc with collaterals |
 Portacath is still in place though |
Wallstent placement into SVC was performed through a vascular sheath placed through the right antecubital vein to the SVC . Once the stent is in place in the SVC, an angioplasty balloon catheter is advanced into the stent and inflated with iodinated contrast to expand the stent and restore flow in the lumen of the vessel.
A final venogram is then done to document flow in the SVC through the previously obstructed segment:
 balloon inflated to open stent |
 venogram with stent in place |
 showing good flow into svc |
Immediately after stent placement, the patient noticed immediate resolution of the facial swelling and puffy eyelids typical of the SVC obstruction Syndrome. Please note that this procedure is palliative only and is designed to provide symptomatic relief from SVC obstruction. It does not address the underlying malignant tumor which will unfortunately continue to grow.
This case was done by Jeffrey Dach, M.D. Interventional Radiologist at Pembroke Memorial Hospital.
