大肠癌肝转移瘤DSA表现和介入治疗

目的　探讨大肠癌不同类型肝转移瘤DSA表现和介入治疗效果评价。方法　回顾分析 10 6例大肠癌肝转移瘤DSA表现 ,介入治疗方案选择和效果评价。结果　 10 6例中 ,单结节和少结节转移灶 (病灶≤ 3个 ) 3 0例 ,占 2 8.3 % ;DSA造影表现以富血供为主 ,多发转移瘤 76例 ,占 71.7% ;DSA造影表现以乏血供为主单发富血供转移瘤行化疗栓塞 ,余经动脉药盒 (PCS)行规律化疗灌注 ,前者生存期较后者明显延长。结论　大肠癌肝转移瘤以多发、乏血供的转移为主 ,介入治疗为肠癌肝转移瘤提供了一条较好的治疗途径。

DSA Appearance and Interventional Therapy of Hepatic Metastasis from Colon Carcinoma

Objective To evaluate DSA appearance and interventional therapeutic effect of different type hepatic metastasis from colon carcinoma. Methods To analyse the DSA images and interventional therapeutic effect in 106 cases retrospectively. Results The group included single-focus and less than 3 foci(30 cases,28.3%),multiple foci(76 cases,71.7%).The single-focus metastasis is hypervascular and the multiple foci is hypovascular mainly. In 106 cases, the hypervascular single-focus took chemo-embolization and the others performed artery chemo-therapy via port-catheter system(PCS) regularly. Conclusion The hepatic metastasis from colon carcinoma is hypovascular and multiple foci mainly.Intervention therapy is a better path relatively.
