13th Annual Global Embolization Symposium & Technologies
Purpose : Big size liver subcapsular hemangioma rupture may lead to significant morbidity and even mortality. Paper presents the experience of Bland Embolization (TAE) of symptomatic and/or giant liver hemangioma.
Material and Methods : TAE was performed to 13 patients with big size liver hemangioma; maximal tumor diameter varied from 7.5 to 25 cm. One of them was referred after surgery, performed because of giant liver mass rupture.
TAE procedure was performed using 100 to 700 micron diameter particles using conventional microcatheter technique. In five cases 2 TAE sessions and in one case 3 TAE sessions has been performed
Results : All patients tolerated the TAE procedure well, no procedural complications were detected. In 8(61.5%) cases follow-up CT showed significant decrease in mass vascularity, showing mass shrinkage in 3 (23.1%) case. In the rest five (38.5%) cases no response to transarterial treatment was detected; all of them underwent TAE one session.
Conclusions : Tumor vascularity decrease and thus, decrease of life-threatening rupture probability is the main rationale for liver hemangioma TAE; in some cases the tumor shrinkage is achievable also. TAE is a safe and efficient technique, which might be suggested as a symptomatic and/or giant hemangioma treatment option in selected patients with tumor significant blood supply in arterial phase.
