640 层CT 对肝癌碘油栓塞沉积不良的临床分析

目的:探讨640层CT对肝癌碘油栓塞沉积不良患者治疗方案的临床指导。方法:21例富血供肝癌碘油动脉栓塞后,复查肝脏CT病灶内碘油沉积不良患者,用640层螺旋CT行CT灌注成像、CT动脉成像检查。结果:21例碘油沉积不良病灶内仍有动脉血供18例,坏死3例,18例有动脉血供病灶由肝动脉供血6例,膈下动脉供血3例,肠系膜上动脉供血4例,右侧副肾动脉供血1例,胃左动脉供血2例,右肾动脉供血2例。结论:640层螺旋CT灌注成像、CT动脉成像,可以准确显示肿瘤病灶碘油栓塞后肿瘤的残留与坏死,特别能精确判断肿瘤病灶血供起源情况,对再次介入治疗具有重要价值。

Clinical Guidance of 640 Layer CT for Liver Cancer Patientswith Bad Iodine Oil Sedimentary Embolization

Objective: To study the clinical guidance of CT 640 layer in treating liver cancer patients with bad iodine oil sedimentary embolism.Methods: 21 patients with rich blood for liver cancer iodine oil artery embolization,and bad iodine oil sedimentation in liver lesions at CT reexamination,suffered with 640-slice CT perfusion imaging and CT artery imaging examination.Results: Among the 21 patients,3 cases had necrosis,and 18 cases still had arterial blood supply in bad lesions,including six cases of hepatic artery blood supply,three cases of diaphragmatic artery blood supply and 4 cases of superior mesenteric artery blood supply,one case of right Accessory renal artery blood supply,two cases of left gastric artery blood supply,and two cases of right renal artery blood supply.Conclusion: 640-slice CT perfusion imaging and CT artery imaging can show precisely tumor remains and necrosis after lesion iodine oil embolism,specially accurate blood supply sources for tumor lesion.So it had important value in once more intervention treatment.
