目的探讨螺旋CT肝动脉期原发性肝癌强化形态及血供与经肝动脉插管栓塞治疗后碘油聚集形态及量的关系。方法回顾性对32例螺旋CT肝动脉期原发性肝癌强化形态及血供表现与其栓塞治疗后肿瘤内碘油分布情况进行对比分析。结果32例肝癌栓塞治疗后肿瘤内碘油分布分为5种类型:均匀致密型(11例)、不均匀致密型(7例)、稀疏型(5例)、缺损型(3例)及混合型(3例)。肝动脉期肝癌肿瘤组织明显强化、或多量强化肿瘤血管影,栓塞后肿瘤内碘油多为均匀致密型或不均匀致密型。肝动脉期肝癌肿瘤组织无或轻度强化、或少量、稀散、僵硬强化肿瘤血管,栓塞后肿瘤内碘油分多为稀疏型、缺损型或混合型。肝动脉期肿瘤内多血供明显强化区,碘油聚集量多。无或轻度强化少血供区,碘油聚集量多较少或无碘油聚集。结论螺旋CT肝动期原发性肝癌强化血管形态及血供对预测其碘油栓塞治疗术后聚集形态及聚集量有重要价值。
Objective To investigate the enhanced morphology of hepatocellular carcinoma (HCC) in the hepatic arterial phase of spiral CT and the relationship between the morphology and quantity of iodized oil collected after hepatic artery embolization and blood supply. Methods Retrospective analysis of 32 cases of hepatic arterial phase hepatic arterial phase enhancement of the enhanced morphology and blood performance and embolization of lipiodol in the distribution of tumor contrast analysis. Results The distribution of lipiodol in 32 patients with hepatocellular carcinoma after thromboembolism was divided into five types: uniformly dense (11 cases), inhomogeneous (7 cases), sparse (5 cases), defect (3 cases) Type (3 cases). Hepatic artery of liver cancer tissue was significantly enhanced, or to strengthen the tumor angioedema, after embolization of tumor lipiodol more uniform or non-uniform compact dense. Hepatic artery of liver cancer tissue without or mild enhancement, or a small amount, scattered, stiff and strengthen the tumor blood vessels, after embolization of tumor iodine oil mostly sparse, defect or mixed type. Hepatic artery tumor blood supply for the obvious enhancement of the area, the amount of iodized oil accumulation. No or mild enhancement of blood supply, lipiodol accumulation of less or no iodized oil accumulation. Conclusion The enhancement of blood vessel morphology and blood supply in hepatic arterial phase of primary hepatocellular carcinoma with spiral CT is of great value in predicting the shape and amount of aggregates after the operation of lipiodol embolization.
