Objective:
To present cases of symptomatic benign liver tumors diagnosed and treated with intra-arterial embolization before surgery.
Material And Methods:
We present the cases of 7 patients diagnosed with symptomatic benign liver tumors that required treatment: 1 focal nodular hyperplasia, 2 giant cavernous hemangiomas, 1 hepatic adenomatosis, and 3 hepatic adenomas. Once the feeding arteries were identified, tumors were embolized with polyvinyl alcohol particles (500μm-700μm) and then the feeding artery was plugged with coils if there was an arterial pedicle to ensure the total vascular exclusion of the tumor. The surgical intervention took place 4 to 7 days after embolization.
Results:
All 7 patients were women (age range, 23-74 years); presurgical intra-arterial embolization was done in 6. In 1 patient with adenomatosis, embolization was done to control intraparenchymal hepatic hemorrhage. In the 6 patients who underwent surgery, the tumor was completely excised and no intraoperative bleeding events or postoperative complications occurred.
Conclusions:
Provided there is a consensus among the multidisciplinary team, embolization is a useful option in the perioperative management of giant and/or symptomatic benign liver tumors.
