Stents and Balloon Angioplasty

Recent advances in interventional radiology have

contributed expandable wire stents and balloon

angioplasty. These stents can be placed across the

stenotic portion of the vena cava. The stents have little

thrombogenic potential and usually remain widely

patent without narrowing for months. Today, place-

ment and use of stents is limited when intraluminal

thrombosis is present. However, after thrombolytic

therapy, stent placement has been noted to be a more

successful approach. After stent placement, patients

experience instantaneous relief of symptoms. The

placement of stents is performed under local anesthe-

sia by radiologists. The placement of a stent appears to

be suitable therapy for the palliation of the symptoms

of SVCS in cases for which other therapeutic modali-

ties cannot be used or are ineffective.

For localized



lesions, balloon angioplasty with or without stenting

has also been shown to significantly reduce the symp-

toms of SVCS.
