目的探讨超声检查在原发性肝癌、TACE术前及术后的临床应用。方法对76例原发性肝癌TACE术前、后行二维超声、CDFI、PW、CDE,观察肿瘤大小、内部回声、血供变化、检测肝固有动脉及门静脉主干血流平均流速等情况。结果 TACE术后大多数肿瘤均有不同程度缩小;肿瘤内部及周边血供明显减少(P<0.05),肝固有动脉平均流速较栓塞前明显下降,门静脉平均流速较栓塞前增快,二者均有统计学意义。能量多普勒(CDE)超声亦可提高低速血流检出的敏感性。结论超声检查,包括二维检查、CDFI、PW、CDE,以其简便、无创伤、无痛苦,无放射线损伤、可多次重复以及价廉为特点。可首选作为原发性肝癌TACE治疗前后的影像学检查方法。
Objective To investigate the clinical application of ultrasonography in the diagnosis of primary liver cancer and before TACE. Methods Two-dimensional ultrasound, CDFI, PW and CDE were performed in 76 patients with primary hepatocellular carcinoma before and after TACE. The changes of tumor size, internal echo and blood supply were observed. The mean velocity of hepatic artery and portal vein blood flow were measured. Results Most of the tumors after TACE were reduced to varying degrees. The blood supply to the internal and peripheral tumors was significantly decreased (P <0.05). The mean velocity of the hepatic artery was significantly lower than that before embolization. The mean velocity of the portal vein was faster than that before embolization. There is statistical significance. Energy Doppler (CDE) ultrasound can also increase the sensitivity of low-speed blood flow detection. Conclusions Ultrasonography, including two-dimensional examinations, CDFI, PW, and CDE, is characterized by its simplicity, no trauma, no pain, no radiation damage, multiple reps and low cost. Can be preferred as primary hepatocellular carcinoma before and after TACE imaging method.
