A male patient underwent conventional transcatheter chemoembolization for advanced recurrent hepatocellular carcinoma(HCC). Even after the injection of 7 m L of lipiodol followed by gelatin sponge particles, the flow of feeding arteries did not slow down. A repeat angiography revealed a newly developed vascular lake draining into systemic veins; however, embolization was continued without taking noticing of the vascular lake. The patient's level of consciousness deteriorated immediately after the procedure, and non-contrast computed tomography revealed pulmonary and cerebral lipiodol embolisms. The patient's level of consciousness gradually improved after 8 wk in intensive care. In this case, a vascular lake emerged during chemoembolization and drained into systemic veins, offering a pathway carrying lipiodol to pulmonary vessels, the most likely cause of this serious complication. We should be aware that vascular lakes in HCC may drain into systemic veins and can cause intratumoral arteriovenous shunts.

Purpose: The purpose is to compare several quantification methods and clarify which quantification method is reliable to estimate diffuse myocardial fibrosis with cardiac mRI in patients with dilated cardiomyopathy (DCm) using myocardial T1 value. methods and Results: Delayed enhancement imaging was performed in 52 patients with DCm and 10 control subjects to identify fibrosis using an inversion time scout sequence. The mean contrast-enhanced myocardial (m) T1 values of the pre and post contrast-enhanced myocardial and left ventricular lumen (L) of control and dilated cardiomyopathy cases were compared. The calculated post m T1 value, pre m T1 value-post m T1 value, and (pre m TI value-post m T1 value)/(pre L T1 value-post L T1 value) were significantly different between the patient group and the control group (344.5 ± 31.6 vs. 390.4 ± 19.3 msec, 239.9 ± 64.2 msec vs. 134.0 ± 28.9 msec, and 0.50 ± 0.11 vs. 0.30 ± 0.60, respectively). (Pre m T1 value-post m T1 value)/(pre L T1 value-post L T1 value) was significantly the most related to the left ventricular ejection fraction (r = 0.66, p Conclusion: (Pre m T1 value-post m T1 value)/(pre L T1 value-post L T1 value) was the most reliable quantification method to estimate the severity of DCm.

本研究的目的是评价主动脉夹层（AD）破裂出血沿肺动脉（PA）延伸的CT表现及其预后因素。在232例Stanford A型主动脉夹层病人中,诊断出21例（9．1％；女性11例；平均70-3岁）。12例病人具有双腔（经典型）,9例病人有主动脉壁内血肿（ImH；闭合的假腔）。基于CT表现,出血可以分为3类：第1类,肺动脉ImH或环绕肺动脉的出血；第2类,出血延伸至小叶间隔；第3类,出血延伸至肺泡内。影响预后的因素包括CT表现和病人的临床特征。21例中有14例（66．7％）进行了急诊手术,

目的应用CT探讨B型多腔(多假腔)主动脉夹层(AD)与双腔(单假腔)主动脉夹层的临床特征和预后。材料与方法本研究经伦理委员会批准并免除了知情同意书。连续选取221例急性B型AD病人(127例男性,平均年龄62岁),应用CT检查进行评估。随访期间(平均60个月)回顾性分析其临床预后,包括AD相关不良事件、AD相关死亡和长期生存率,并与双腔AD病人比较。应用带有秩和检验的Kaplan-meier分析其发病后10年内生存率。应用Cox比例危险率模型估计AD相关不良事件和死亡的风险。结果 221例病人中,201例(91.0%)在最初的CT检查中被确诊为双腔AD,20例(9%)在最初(n=16)和随诊CT(n=4)检查中被确诊为多腔AD。20例多腔AD病人中,15例(75%)发生AD相关不良事件,9例(45%)病人死于AD相关并发症。多腔AD病人的生存率较双腔AD病人明显更差(P=0.0002)。多变量分析显示,多腔AD假腔的出现是AD相关死亡的最危险因素(风险比,5.61;95%CI:2.44～12.90;P<0.001)。结论多腔AD占急性B型AD的9%。多腔AD是AD相关死亡的一个有力预测因子。
