Intra-cardiac echocardiography-guided stent implantation into stenosed superior vena cava in a patient with a history of contrast anaphylaxis

A 37-year-old patient, who suffered from a repeated superior vena cava (SVC) syndrome, was scheduled for stent implantation into SVC, but suffered from contrast anaphylaxis. To monitor the procedure, we used intra-cardiac echocardiography and successfully implanted a stent. Placing an intra-cardiac...

Description
Summary:A 37-year-old patient, who suffered from a repeated superior vena cava (SVC) syndrome, was scheduled for stent implantation into SVC, but suffered from contrast anaphylaxis. To monitor the procedure, we used intra-cardiac echocardiography and successfully implanted a stent. Placing an intra-cardiac echocardiographic catheter in the main pulmonary artery and facing towards the right, we could readily visualize stenosis in the SVC and inflation of the stent. Also looking up from right atrium, we noted proximal obstruction of the stent and confirmed the relief of obstruction after additional balloon dilation. This report leads to new application of intra-cardiac echocardiography for intervention of structural and vascular diseases other than inter-atrial septum.
