门静脉

The morphology and characteristics of enhancement were studied, and compared with histopathologic and angiographic findings.

结果：74％的肝细胞癌在动脉期呈高密度，76％在门静脉期呈低密度。10例门静脉期等密度的病灶在动脉期均呈高密度。

Results The 47 cases etiologies of various hepatic perfusion disorders were classified: arterioportal fistulae in 9 cases, inflammatory hyperemic changes in 8 cases, portal venous inflow and hepatic venous outflow obstruction in 13 cases, steal phenomenon by tumors in 4 cases, aberr...

结果47例肝脏灌注异常，有以下几种情况：肝动脉门静脉瘘9例，炎症性充血8例，门静脉、肝静脉阻塞13例，肿瘤盗血现象4例，肝脏迷走血供2例和其它原因1例。结论多层螺旋CT三期增强扫描是评价肝脏异常灌注的有效方法。

Objective To evaluate the portal hemodynamic changes of patients with hypersplenism before and after radiofrequency ablation,RFA.

目的 探索肝硬化门静脉高压性脾功能亢进症在射频消融(radiofrequency ablation，RFA)治疗前后门静脉血流动力学的变化。

Results 33 cases of CTPV were all showed collateral veins, which were biliary collateral veins of the portal vein (n=33), gastric collateral veins (n=25), pancreaticoduodenal region collateral veins (n=14), parumbilical collateral veins (n=2). The collateral veins were appeared as soft tissue density on precontrast scan, with generally no enhancement on arterial phase, but on venous phase, they were appeared as multiple punctuate, strip, nodous or thin reticulate enhanced vessels, which were with tortuous, abnormally dilated, and cavernous in shape.

结果 33例全部显示侧支静脉，其中显示33例胆支、25例胃支、14例胰十二指肠后上静脉和2例脐旁静脉，侧支静脉CT平扫表现为软组织密度影，动脉期一般无强化，门静脉期显示多发点状、条状、结节状或细网状的强化血管影，走行扭曲，异常扩张，呈海绵样改变；22例显示门静脉栓子，14例显示肝脏灌注异常，12例显示胆系改变，25例显示脾肿大。

3PH was done in group M and T. Then the rats in B group and M group were injected normal saline via portal vein, and those in T group were injected with SHCs suspension. Four week later, the level of serous alanine aminotransferaseand glutamic oxalacetic transaminase were tested, and liver pathological changes observed. Frozen sections of T group were observed under fluorescent microscope.

将实验用同一近交系SD大鼠30只随机平均分成空白对照组、损伤造模组和SHCs移植组。B组腹腔注射生理盐水，M组、T组腹腔注射CCl4.24 h后戊巴比妥腹腔麻醉，消毒开腹，M、T组行2/3肝切，B、M组门静脉注入生理盐水，T组门静脉注入经膜荧光标记SHCs悬液。4周后，采血测血清谷丙转氨酶、谷草转氨酶，并取病理标本做冰冻切片荧光显微镜下观察及HE染色普通光镜下观察。

In conclusion, real-time US is a useful and reliable modality in detecting periportal vessels and differentiating PPCC from the hepatic artery.

实时间超音波对傍门静脉血管的侦测及鉴别傍门静脉侧枝循环与肝动脉，是有用且可信赖的工具。

On long-term follow-up, about 5% of 6-thioguanine recipients have evidence of non-cirrhotic portal hypertension due to periportal liver fibrosis or nodular regenerative hyperplasia.

在长期随访过程中， 6-硫鸟嘌呤组约有 5%的患儿出现了非肝硬化性门静脉高压，这是由门静脉周围肝组织纤维化或结节再生性增生所引起的。

Real-time ultrasound was used to analyze the morphological characteristics of periportal collateral circulation and the hepatic artery in hepatocellular carcinoma patients with portal vein invasion.

为了分析肝癌并门静脉侵犯病人，其傍门静脉侧枝循环与肝动脉，在实时间超音波上的型态特徵。在过去5年期间，总共收集17个病人，其中14个男性，3个女性，年龄27岁到76岁。

During a 5year interval, a total of 17 HCC patients with main portal vein thrombosis and detectable periportal vessels were collected: 14 men and 3 women, aged 27 to 76 veal's old.

这些病人全都是肝癌并主门静脉栓塞，同时俱有可侦测到的傍门静脉血管。
