  • Title: Stenting in malignant vena caval obstruction.
    Author: Oudkerk M, Heystraten FM, Stoter G.
    Journal: Cancer; 1993 Jan 01; 71(1):142-6. PubMed ID: 8416711.
    Abstract:
    BACKGROUND: For patients with recurrent vascular obstruction of the vena cava due to tumor regrowth after chemotherapy or radiation therapy and occasionally surgery, no current therapy is available. With the development of intravascular stenting, a new option becomes available in the treatment of a vena caval syndrome. METHODS: Twenty-two patients were treated for malignant obstruction of the vena cava by single, double, and triple Z-type metal stents. All patients had been pretreated extensively and their disease was not amenable to other therapeutic techniques at the time of stenting. RESULTS: Correct positioning of the stents was achieved in all patients. In 68% of patients (n = 15), the symptoms completely disappeared without recurrence until death as a result of tumor progression. In 18% of patients (n = 4), a remarkable improvement was observed, but there was no complete disappearance of symptoms. In 14% of patients (n = 3), reocclusion of the vena cava occurred. The median survival time was 3.0 months (range, 1 week to 9 months). CONCLUSIONS: The application of Z-type metal stents in patients with recurrent malignant obstruction of the vena cava appears to be a useful palliative procedure.
