Hepatic artery embolisation--new approach for treatment of malignant carcinoid syndrome

Abstract

A transcatheter embolisation was carried out for treatment of a patient suffering from hepatic metastases of a malignant carcinoid tumour. Recurrent and very severe carcinoid symptoms could be observed; a bronchial carcinoid supposingly the primary tumour without characteristic symptoms was removed six years before. The carcinoid symptoms became resistant to pharmacological agents and finally ended in life-threatening clinical complications. The transcatheter hepatic artery embolisation was successfully performed and repeated three months later. After embolisation relief of carcinoid symptom and a significant decrease in 5-hydroxyindole acetic acid (5-HIAA) urinary excretion lasting for eight months could be observed. There were no serious complications with adequate pharmacological cover, however, a transient fever, leucocytosis, abdominal pain and an increase in serum transaminase activities occurred after the procedure. The transcatheter hepatic artery embolisation should be a method of choice for treatment of patients with carcinoid metastases producing severe carcinoid symptoms resistant to pharmacological agents.
