  • Title: Stenting in malignant and benign vena caval obstruction.
    Author: Laing AD, Thomson KR, Vrazas JI.
    Journal: Australas Radiol; 1998 Nov; 42(4):313-7. PubMed ID: 9833367.
    Abstract:
    Expandable metallic stents have been used with considerable success for the palliation of malignant vena caval obstruction. The role of stenting in vena caval obstruction of benign aetiology is less well defined. A review of 11 patients stented for vena caval obstruction and a review of recent series in the literature is presented. Of the 11 patients, seven patients had involvement of the superior vena cava (SVC), and four patients had inferior vena caval (IVC) obstruction. Seven cases had malignant vena caval obstruction, with a benign aetiology (SVC n = 3; IVC n = 1) in the other four cases. All seven patients treated with SVC stents experienced complete resolution or significant improvement in symptoms with no recurrence over the duration of available follow-up, over an average of 4.3 months (range: 1 week-12 months). Only one of four IVC lesions stented resulted in a good clinical response. All four patients with vena caval obstruction of benign aetiology had a good outcome. One patient experienced a small pulmonary embolus following SVC stent insertion without further sequelae. No other serious complications were encountered. Stenting can provide prompt relief of vena caval obstruction with low morbidity, and high patency rates in both benign and malignant vena caval lesions.
