Radiological stenting provides effective palliation in malignant central venous obstruction. Abstract Text:

Malignant superior vena caval obstruction (SVCO) due to lung cancer carries a poor prognosis and response to palliative radiotherapy is variable. Eighteen patients presenting with the appearance of malignant SVCO (thirteen due to primary bronchial tumours) in a four year period from June 1995 to July 1999 underwent venography with a view to placement of an expanding metal stent under radiological control. Fourteen patients were male and four female with a mean age at presentation of 65 years (range 44-84 years). At venography only three patients had isolated SVC stenosis, fivealso had brachiocephalic, internal jugular or subclavian vein stenoses and one had an isolated right brachiocephalic stenosis. Venography demonstrated thrombus in eight of the remaining patients, seven in association with stenosis. In one patient stenosis of the SVC was thought to be due to radiation fibrosis as no mass was visible. All underwent Seldinger catheterization of the great veins via a right femoral puncture with deployment of the stent over a guide wire. Balloon angioplasty was performed prior to stent placement in eight patients. The eight patients with thrombus underwent thrombolysis using rt-PA (recombinant tissue-type plasminogen activator) with subsequent stent placement in seven. Radiological relief of obstruction with abolition of collateral flow was observed in all cases. One patient required further stenting for recurrent obstruction after 160 days of palliation. The median duration of palliation after stenting was 87 days. No procedure-related morbidity was observed. Thrombolysis was of value in patients with occlusive thrombus, either in isolation or complicating a malignant stricture, where radiotherapy may not have been effective. Radiological stenting is a safe technique which offers rapid palliation of SVCO.
