Figure 5 Intimal Proliferation in Stent

Intimal proliferation was identified 10 months after placement of a Palmaz stent (left panel, arrows) in a 6-month-old infant with superior vena cava (SVC) occlusion as a result of extracorporeal membrane oxygenation cannulation. The obstruction was successfully balloon dilated at re-intervention (right panel).
