[Unresectable hepatic adenomas. Management by selective hepatic artery embolization]. / Adénomes hépatiques non résécables. Place de l'embolisation artérielle dans la conduite thérapeutique.

ABSTRACT

Four patients with unresectable hepatic adenoma underwent selective hepatic artery embolization. Non-operability was related to the size and the situation of the tumor, and the clinical background. The only subsequent postembolization syndrome was one case of acute renal failure, reversible after diuretic treatment. In 3 cases the decrease in tumoral size was delayed and appeared six months after the first embolization, allowing surgical resection in 2 cases. Because of lack of tumoral devascularization and presence of residual nodules on the resected specimen, this technique is not a satisfactory alternative to surgery, at least with the employed technique. However, preoperative selective hepatic artery embolization can play an important role in the management of hepatic adenomas as it may permit safer surgical resection.
