Hepatic hemangioma: an analysis on the impact of the differences in blood supply on interventional effectiveness and complications / 中华肝胆外科杂志

ABSTRACT

Objective To analyze the impact of the differences in blood supply to hepatic hemangiomas on interventional treatment effectiveness and complications.Methods A retrospective study was conducted on 322 patients with liver hemangiomas treated from January 2008 to December 2015 in Tianjin Third Central Hospital.The hemangiomas were diagnosed and classified into 3 groups according to the blood supply to the hemangiomathe rich blood supply group (n =128),the moderate blood supply group (n =104) and the poor blood supply group (n =90).The hemangiomas were embolized via the hepatic artery,and the therapeutic effect and complication were compared and analyzed among the 3 different groups.The mean follow-up was 12 months.Results The therapeutic effect of hepatic artery embolization was optimal for the rich blood supply group in the first 3-months of follow-up (the significant efficiency,effective rates were 18.8％ and 35.2％ respectively).There was no significant difference between the rich blood supply group and the moderate blood supply group at 12th month follow-up.The treatment effect on the poor blood supply group was significantly worse than the other two groups on follow-up.Complications after treatment occurred most commonly in the rich blood supply group and it was the least common in the poor blood supply group (the incidence rates were 43.8％,36.6％ and 8.9％ respectively).However,severe post-treatment complications were apparently more common in the poor blood supply group than the other two groups.Conclusions The therapeutic effects of transcatheter arterial embolization on hepatic hemangioma can differ because of the diversity in blood supply.In clinical practice,attention should be paid to the proper choice of treatment according to the blood supply to the lesion.Serious complications can occur after treatment.
