摘要

射頻燒灼術已經被廣泛的使用在許多實質性腫瘤的直接局部治療上。它也已被證實在早期肝癌的治療上大有可為。射頻燒灼術的併發症多為對鄰近組織的局部損傷與出血。而隨著導針進出所引起的癌組織轉移即所謂導針路徑轉移（needle tract seeding）雖然少見，卻是一個不可忽視的併發症。導針路徑轉移自然多發生在沿著導針進出的路徑。我們報告兩例肝癌患者，於經皮穿肝做射頻燒灼術後產生罕見的導針路徑轉移－腹腔內遠端轉移。這兩例病患都接受了手術切除轉移的肝癌。

Radiofrequency ablation (RFA) has been widely used in direct local destruction of a variety of solid tumors. It had been proved to be a promising treatment for early stage hepatomas. The complications of RFA were mostly due to local damage of the surrounding tissues or hemorrhage. Needle tract seeding was also a rare but significant complication after RFA. The tract seeding of tumors always occurred along the needle tract. We presented 2 cases of an unusual type of tract seeding - intraperitoneal distant implantation after percutaneous RFA for hepatomas. The metastatic tumors were treated with surgical resection.
