Superior vena cava stent placement: results with the Wallstent endoprosthesis.

PURPOSE: To assess the clinical success and short-term patency of the Wallstent endoprosthesis in the treatment of superior vena cava (SVC) syndrome. MATERIALS AND METHODS: Twenty-one 14-mm-diameter endoprostheses were implanted in 15 patients (mean age, 60 years) treated for SVC syndrome due to malignant compression (n = 14) or postirradiation fibrotic stenosis (n = 1) of the SVC. RESULTS: Immediate technical success was achieved in all patients. Two early complications occurred: retroperitoneal hemorrhage due to venous iliac tear and early stent thrombosis. In the 14 patients without early stent occlusion, stent placement resulted in complete relief of SVC syndrome; clinical success was 93%. SVC syndrome did not recur from 1 to 14 months, until the patient died (n = 11) or until the end of the study (n = 3). Helical CT showed a patent stent in five patients, respectively, at 3, 6, 8, 10, and 11 months. CONCLUSION: SVC stent placement has good clinical results and a high patency rate at short-term follow-up in patients with SVC syndrome.

Cardiac angiosarcoma revealed by lung metastases.

Cardiac angiosarcoma is a rare tumour with very poor prognosis especially in patients with metastatic disease. We present the case of a 43 year old patient with angiosarcoma revealed by open lung biopsy for multiple pulmonary metastases. Cardiac symptoms were limited to a moderate pericarditis and no echocardiographic sign of heart tumour was observed. The clinical outcome was rapidly fatal despite chemotherapy. The cardiac primary tumour was diagnosed at autopsy. We emphasize the difficulties of diagnosing cardiac angiosarcoma and confirm the limited value of echocardiography for this diagnosis.
