目的 研究治疗原发性肝癌中,程序性肠系膜上动脉、腹腔动脉及肝总动脉造影在TACE发现肝癌非常规供血动脉的作用及其临床意义.方法 回顾分析2005年1月至2009年12月,所有在南京医科大学附属第一医院放射科首次行TACE治疗的原发性肝癌患者的血管造影资料及介入手术治疗报告.根据造影程序将其分为两组:A组526例患者常规行肠系膜上动脉、腹腔动脉及肝总动脉造影,B组850例只行肝总动脉的造影,均在明确病灶的供血动脉后进行TACE治疗.两组患者动脉造影时均在肿瘤染色不佳或无染色时寻找异位肝癌供血动脉,对肿瘤的供血动脉为腹腔干-肝总动脉之外的血管分别根据其起源进行分类及统计,并就两组的发现率进行统计学分析,比较发现率的高低并分析产生此统计学差异的原因.结果 两组肝癌的肠系膜上动脉分支供血的发现率为A组14.1%(74/526)、B组8.9%(76/850);胃左动脉分支供血的发现率为A组6.7%(35/526)、B组3.3%(28/850);膈动脉供血的发现率分别为A组4.6%(24/526)、B组2.6%(22/850);腹腔干供血的发现率分别为0.5%(3/526)、0(0/850).此4组侧支血管的发现率A组均高于B组(P<0.05).而对于胃十二指肠动脉、右肾动脉、肋间动脉、胸廓内动脉及脾动脉的肝癌异常供血的发现率2组差异无统计学意义(P>0.05).结论 程序性造影可以提高肝癌侧支供血动脉的发现率,特别是提高副肝动脉对肝癌供血的发现率,在提高肝癌的早期完全栓塞率,控制肿瘤的复发中有一定的意义. 相似文献

The purpose of this study was to investigate the clinical outcomes of bland embolization using superabsorbent polymer microspheres
(SAP-TAE) as an initial therapeutic option for previously untreated hepatocellular carcinoma (HCC) ineligible for resection
or ablation. Fifty-nine patients with previously untreated HCC unamenable to surgery or ablation underwent bland embolization
using 100- to 200-μm reconstituted SAP particles (SAP-TAE) as the initial treatment. SAP-TAE was repeated as needed based
on tumor response but was switched to chemoembolization when necessary to control residual or progressive tumor. Early tumor
response was assessed by contrast-enhanced CT according to RECIST and EASL criteria 1 month after the initial SAP-TAE. The
overall survival was calculated using the Kaplan–Meier method. The overall mean follow-up period was 30.6 months (range, 7–59 months).
A total of 121 sessions of SAP-TAE were performed, with 1–5 sessions per patient (mean, 2.1 sessions). The mean period of
repeated SAP-TAE was 15.6 months (range, 1–51 months), and it exceeded 1 and 2 years in 32 (54%) and 15 (25%) patients, respectively.
Thirteen (22%) patients underwent repeated SAP-TAE alone, and the remaining 46 (78%) patients underwent subsequent chemoembolization.
No major complication was observed and postembolization syndrome was minimal after SAP-TAE in all patients. Response rate
was 14% and 66% by RECIST and EASL criteria, respectively. Overall survival rates were 100% and 83% at 1 and 2 years, respectively,
and median survival time was 30 months. In conclusion, SAP-TAE was a safe and repeatable option as the induction therapy for
HCC unamenable to surgery or ablation, despite the high incidence of converting to TACE during the total course. 相似文献

小肝细胞癌的CT诊断 总被引:2,自引:0,他引:2
对118例经手术病理证实的小肝细胞癌(SHCC)进行了前瞻性CT研究。男109例,女9例,年龄18~76岁,平均49.5岁。118例均作了增强前和增强后扫描。其中20例还加进床/同层动态团注增强CT(DLB一CT、DSB一CT),5例作了4h延迟CT(D一CT),12例作了动脉造影CT(CTA),其中5例又加作了经动脉门脉造影CT(CTAP)。增强前SHCC主要表现为低密度(93.2%)。增强后动脉期呈明显早期增强,但密度很快下降,在门脉期呈低密度表现。在D一CT和CTAP图像上呈低密度,而CTA为显著高密度。不同CT方法检出SHCC敏感的排列顺序为:增强前CT<增强后CT<DIB一CT或D-CT<CTA或CTAP。 相似文献

Arterial Embolization of Unresectable Hepatocellular Carcinoma with Use of Microspheres, Lipiodol, and Cyanoacrylate 总被引:3,自引:0,他引:3
Rand T Loewe C Schoder M Schmook MT Peck-Radosavljevic M Kettenbach J Wolf F Schneider B Lammer J 《Cardiovascular and interventional radiology》2005,28(3):313-318
We performed a retrospective analysis of 46 patients with histologically confirmed hepatocellular carcinoma (HCC) who were treated with transarterial embolization (TAE) of the hepatic arteries. To induce permanent embolization, microspheres (Embosphere; 100 to 700) and a mixture of ethiodized oil (Lipiodol Ultrafluide) with cyanoacrylate (Glubran) was injected. A total of 106 TAE procedures were performed. Cumulative survival rates were calculated. No patient died during embolization or within the first 24 hours. Severe procedure-related complications were observed in 2 patients. At the time of analysis, 38 of 46 patients were alive. The 180-, 360-, 520-, and 700-day cumulative survival rates for the total study population were 80.6%, 70.7%, 70.7%, and 47.1%, respectively, with a median survival of 666 days. TAE with the use of microspheres and Lipiodol and cyanoacrylate for unresectable HCC is a feasible treatment modality. Bland embolization with the use of microspheres can be used in patients for whom chemoembolization is not desired. 相似文献
