目的 评价选择性介入治疗在原发性肝癌（HCC）门脉高压症中的应用价值。 方法 2008年11月－2011年3月，收治65例临床明确诊断的HCC伴门脉高压症患者，选择性使用肝动脉化学疗法（化疗）栓塞术、脾栓塞术、门静脉化疗栓塞术、门静脉支架、胃冠状静脉栓塞术等介入术式，术后通过观察临床指标、定期复查影像检查等了解病变转归，随访生存期并评价疗效。 结果 65例HCC患者均合并不同程度门静脉高压，其中门静脉癌栓46例中有37例显示肝动脉-门静脉分流，通过肝动脉及门静脉化疗栓塞术进行主瘤体及癌栓治疗。11例行门静脉支架置入术，支架置入后门静脉压较术前明显下降（P＜0.01），支架中位通畅时间为5.8个月。39例行胃冠状静脉和（或）胃短静脉栓塞术，术后有4例再次发生门脉高压性出血，再出血率10.26%。18例行脾动脉栓塞术，术后3个月血小板较术前显著升高（P＜0.01）。随访术后3、6、12及24个月的生存率分别为90.77%、69.23%、35.38%及13.85%。 结论 选择性联合使用各种介入术式是治疗HCC及其相关性门脉高压症的一种有效方法，可有效预防高危风险，延长患者生存期。
目的 探讨囊性脑膜瘤的磁共振表现、表观弥散系数（ADC）图的影像特点、ADC值与病理分级的关系及ADC值对判断不同病理亚型脑膜瘤的价值。 方法 回顾性分析2003年3月－2007年12月18例经病理证实的囊性脑膜瘤患者的磁共振表现，其中男8例，女10例，平均年龄45.6岁。在ADC图上分别测量肿瘤实质、瘤周水肿、囊变区的平均ADC值（均取4～6个区域，取平均值），比较不同病理亚型、不同病理分级的肿瘤实质、瘤周水肿、囊变区的ADC值差异是否有统计学意义。 结果 良恶性脑膜瘤肿瘤实质ADC值差异无统计学意义（P＞0.05）；囊性脑膜瘤各亚型间的肿瘤实质、瘤周水肿的ADC值差异无统计学意义（P＞0.05）；肿瘤实质、囊变区与瘤周水肿平均ADC值相比差异均有统计学意义（P＜0.05）。 结论 ADC值可区分肿瘤实质、囊变区及瘤周水肿，但对脑膜瘤亚型及良恶性的甄别需结合常规MRI与增强的征象。Objective To explore the MRI imaging manifestation, features of apparent diffusion coefficient (ADC) map and the relationships among ADC value, pathologic grading and pathologic subtype of cystic meningioma. Methods The clinical data of 18 patients (8 males and 10 females, with an average age of 45.6 years) with cystic meningiomas confirmed by pathologically examination were retrospectively analyzed. The ADC values of tumor parenchyma, peritumoral edema, cystic regions and the contralateral normal brain of the tumor parenchyma were measured and analyzed.The ADC value of the tumor parenchyma, peritumoral edema, cystic region were measured and then compared with the pathological findings. P value of less than 0.05 was considered as having a statistically significant difference. Results There was no significant difference in ADC values between benign and malignant meningioma and also among the tumor parenchyma, periedema and cystic region in different pathological subtypes. The difference in ADC values amongst tumor parenchyma, peritumoral edema and cystic region were statistically significant (P＜0.05). Conclusions Although ADC quantitative measurement allows the differentiation of the tumor parenchyma, cystic region and peri-edema, it is need to combined with conventional MR examination to assess tumor malignancy as well as grading in cystic meningioma.
目的 探讨急诊行子宫动脉灌注药物栓塞术治疗剖宫产后切口妊娠的可行性和临床价值。 方法 2009年10月－2011年12月，对17例临床证实切口瘢痕妊娠并阴道出血患者，急诊行双侧子宫动脉灌注甲氨蝶呤并超选择栓塞术，术后通过观察人绒毛膜促性腺激素（HCG）水平、阴道出血及术后清宫术来评价疗效。 结果 17例患者急诊行子宫动脉灌注栓塞术成功，术后阴道出血均停止或减少，HCG水平均明显下降，3例因孕囊自行排除而未行清宫，14例术后2～4 d行胚胎钳刮术，术中出血量较少。所有患者1周后均治愈出院。 结论 子宫动脉灌注栓塞术是治疗剖宫产术后切口瘢痕妊娠的一种有效方法，可及时治疗阴道大出血，促进杀胚，并为术后清宫提供安全保障。
【摘要】 目的 探讨磁共振动态增强扫描及磁共振弥散加权成像（diffusion weighted imaging，DWI）对肝癌经导管动脉内化学栓塞（transcatheter arterial chemoembolization，TACE）治疗后的肿瘤残余及复发的判断价值。 方法 2009年1月-2010年10月，对28例经证实的肝癌患者在TACE治疗前、治疗后3~7 d及治疗后1~2个月、3~6个月行磁共振动态增强及DWI扫描，动态测量表观弥散系数（apparent diffusion coefficient，ADC）值，与数字减影血管造影（digital substraction angiography，DSA）检查对照，评价动态增强扫描及DWI对肿瘤残留或复发的检出能力。〖HTH〗结果 对肿瘤残余及复发的显示，动态增强扫描灵敏度为90.0%，特异度为96.9%；DWI灵敏度为96.7%，特异度为93.8%；动态增强扫描与DWI相结合的灵感度为100.0%，特异度为99.5%；DSA灵敏度和特异度分别为96.7%、100.0%。TACE治疗前所有肿瘤实质的ADC值为（1.134±0.014）×10-3 mm2/s；TACE治疗后3~7 d ADC值为（1.162±0.016）×10-3 mm2/s；TACE治疗后1~2个月碘油沉积较好，无明显残余或复发病灶的ADC值为（1.175±0.015）×10-3 mm2/s，3~6个月后随访病灶ADC值为（1.179±0.017）×10-3 mm2/s；TACE治疗后1~2个月碘油沉积不完全或无明显沉积病灶ADC值为（1.147±0.016）×10-3 mm2/s，3~6个月后随访病灶实质平均ADC值（1.142±0.012）×10-3 mm2/s。 结论 将动脉增强扫描与DWI相结合可提高对TACE治疗后肝癌残余及复发判断的灵敏度及特异度；对肿瘤组织平均 ADC值的动态测量、观察可及早判断肿瘤复发的可能性。【Abstract】 Objective To evaluate the dynamic contrast-enhanced MRI and diffusion weighted imaging (DWI) in judging the remnant and recurrence on hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE). Methods Between January 2009 and October 2010, 28 patients with HCC underwent dynamic contrast-enhanced MRI and DWI before and after TACE 3-7 days, 1-2 months and 3-6 months, respectively, and the apparent diffusion coefficient (ADC) value of the tumor were also measured at above mentioned time points. The sensitivity and specificity of dynamic contrast-enhanced MRI and DWI in diagnosis of residual tumor and recurrent cancer was qualitatively evaluated by comparing with the DSA results. Results Compared with DSA, the sensitivity and specificity of dynamic contrast-enhanced MRI were 90.0% and 96.9% by revealing the remnant and recurrence of HCC, while the sensitivity and specificity of DWI were 96.7% and 93.8% respectively. Combining dynamic contrast-enhanced MRI and DWI the sensitivity and specificity were improved to 100.0% and 99.5%, respectively. The mean ADC value of tumor before and after 3-7 days of TACE were (1.134±0.014)×10-3 and (1.162±0.016)×10-3 mm2/s, respectively. The mean ADC value of tumor without and with remnant and recurrence after 1-2 months and 3-6 months follow up were (1.175±0.015)×10-3, and (1.179±0.017)×10-3 mm2/s; (1.147±0.016)×10-3 and (1.142±0.012)×10-3 mm2/s, respectively. Conclusions Combining dynamic contrast-enhanced MRI and DWI could improve the sensitivity and specificity to detect the remnant and recurrence of HCC after TACE. Measuring the ADC value during follow up of HCC patients after TACE could predict the probability of tumor recurrence.
