We report a case of primary synovial sarcoma of the kidney showing the following imaging patterns: The tumor occupied the entire left kidney, invaded into the left renal vein and inferior vena cava, and the tumor thrombus extends upward to the level of right atrium, downward to infrarenal IVC.

我们在此报告一个肾脏原发性滑液肉瘤伴随有以下转移的影像特徵：肿瘤占据整个左肾，侵入左边肾静脉以及下腔静脉，并且肿瘤栓塞向上延伸到右心房与向下到肾脏下段下腔静脉。

Results: 68.9%of the lesions located superficially; There were 79.3%intracranial AVMs with volume ranged 0～30mm3; 16.9%intracrnial AVMs had associated with aneurysm including feeding artery aneurysm and intranidal aneurysm; There were 8.2%intracranial AVMs with venous stenosis.

结果：表浅部位者占68.9％；体积为0～30mm3者占79.3％；严重盗血者占19.7％；发现与颅内AVM相关的动脉瘤占16.9％；发现中央静脉引流及混合静脉引流者共53.0％；有引流静脉狭窄者占8.2％。

In the early stages, the intrapulmonary eins are connected to the eins of the systemic circulation.

在发育早期，肺内静脉与体循环静脉相连，而到了晚期，肺内静脉与起源于心房的原始肺静脉相连。

The faciform ligament is an important sign of laparoscopic liver surgery and a way of collateral circulation of liver. The superior liver artery found and named in this research can be an important sign to judge the position of hepatic vein. The operation pathway by cutting down the perihepatic ligament next to the superior border of liver is a quick way with little blood. It is difficult to hurt diaphragm and hepatic vein, and the secundum porta hepatic can be showed clearly. As a rule, we break the hepatic vein in the hepatic parenchyma on laparoscopic hepatectomy. But in some situation, extrahepatic treatment was used.

镰状韧带是腹腔镜肝脏外科入路的重要标志，是肝脏侧枝循环的重要途径；本文所发现并命名的肝上动脉可以作为判定肝静脉位置的重要标志；紧贴肝上缘打开肝周韧带，不易损伤膈肌和肝静脉，出血少、速度快，可以使第二肝门获得良好的手术显露；腹腔镜肝切除时一般在肝实质内切断肝静脉，在个别情况也可以预先在第二肝门结扎切断肝静脉。

Methods Twenty-five cases of giant PLCs, with a mean diameter of 14.78cm, were evaluated. All of the tumors involved the main hepatic veins and /or retrohepatic vena cava. Before resection the tumor was fully exposed and an occluding tape, when neccessary, was placed around the vena cava.

25例累及第二第三肝门的肝癌，平均肿瘤直径14.78cm，分别压迫主要肝静脉根部或/和肝后腔静脉；进腹充分暴露肿瘤后在间歇性第一肝门阻断下切除肿瘤，切肝前根据需要预置腔静脉阻断带备用。

Methods PICC was performed in 33 patients while subclavicular vein insertion in 30 patients for comparison in order to analyse prospectively the advantages and disadvanges of PICC .

方法分别对33例和30例腹部恶性肿瘤围手术期患者，随机应用了经肘部静脉穿刺置入PICC导管和经锁骨下静脉穿刺上腔静脉置管，实施胃肠外营养，比较两种导管的优劣。

Objective To compare the curative effect of high ligation+exfoliation and subfascial endoscopic perforator surgeryfor superficial varicose veins in calf+invagination spot-striping surgery in great venous varicosity.

目的对比研究传统大隐静脉高位结扎加分段剥脱术和腔镜下小腿交通静脉断离加大隐静脉内翻式点状抽剥术的疗效。

Objective To uate the effect of external valvuloplasty of superficial femoral vein valve combined with subfascial endoscopic perforator vein surgery in treating recurrent lower extremity vein insufficiencyLEVI）.

目的 评价股浅静脉带戒术联合内镜下交通静脉离断术（subfascial endoscopic perforator vein surgery，SEPS）治疗复发性下肢静脉功能不全（lower extremity vein insufficiency，LEVI）的疗效。

Hepatic veno occlusive disease is caused by stenosis or obstruction of central vein and sublobular veins of hepatic lobules resulting in portal hypertension.

肝小静脉闭塞病是肝小叶中央静脉和小叶下静脉损伤导致管腔狭窄或闭塞而产生的门静脉高压症，临床表现类似于BCS，诊断依靠肝组织活检。
