门静脉动脉化最初是由Cohn于1952年根据门静脉高压门腔分流术后肝脏供血大量减少而提出的。

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. The hepatectomies were performed under intermittent portal triad clamping.

"This clinical study, which is the largest to examine vena cava filter retrievals, reveals breakthrough results about physicians' ability to retrieve Cook's Cook's Günther Tulip months after implantation," said Dr. Smouse."Our hope is that these results become the criterion to which all vena cava filters must measure up to."

Smouse博士说，这项最大的调查腔静脉滤器回收的临床研究获得了突破性结果，医生能够在植入几个月后回收Günther Tulip腔静脉滤器，我们希望这些结果成为所有腔静脉滤器必须达到的标准。

Objective To examine biomechanic change of vessel wall and re-stenosis after dilation of stenosed vena cava in dogs and to infer possible mechanisms of hypotonic luminal benign stenosis in an attempt to provide new evidence for clinical study of potential mechanisms of vena cava stenosis.

目的 通过实验动物研究，初步探讨下腔静脉狭窄扩张后的管壁生物力学特征的改变，推测再狭窄的可能机制。

Methods: The model was established with two cuff technique; The donor was perfused through the abdominal aorta with cold perfusate; The anastomosis of the suprahepatic vena cava was sutured end to end with 8~0 nylon line, and the continuity of portal vein and infrahepatic vena cava were established by means of cuff method respectively. The bile duct anastomosis was performed with internal stent.

采用二袖套法行大鼠原位肝移植，供体经腹主动脉进行肝脏冷灌注，肝上下腔静脉采用手缝合法进行吻合；门静脉和肝下下腔静脉用袖套法吻合；胆总管采用单管内支架胆管端端吻合。

To observed the best ablation temperature of getting effectively electrical isolation, first, we selected three mongrel dogs, if transseptal catheterization was performed successfully, then the pulmonary vein ostia、superior vena cava ostia and inferior vena cava ostia were ablated with TTB-USA (predetermined temperature: 50℃、55℃、60℃ respectively, ablation time: 60 seconds).

为观察不同温度超声消融入心静脉口对电传导的影响，确定最佳的消融温度与消融时间。我们首先选用健康成年犬3只，如果房间隔穿刺成功，则行超声消融肺静脉口与上、下腔静脉口；如果不成功，则单纯消融上、下腔静脉口。

After anesthesia and tracheal intubation, the heart was exposed through median sternotomy. Conventional,CPB procedure was performed by cannulation of an 8F infant arterial cannula in the ascending aorta and two 20F venous cannulae in the superior vena cava and the inferior vena cava.

麻醉后气管插管，从胸骨正中进胸，在上、下腔和主动脉插管建立CPB动物模型，分别进行DHCA和常温CPB。

Inferior vena cava is the largest vein in human body , wider than the hepatic vein, so some researchers propose direct intrahepatic portacaval shunt to lead some portal blood flow directly into vena cava, hoping to obtain more stable bypass.

DIPS术是在肝内门静脉与肝后段下腔静脉之间建立肝内分流，将部分门静脉血液直接分流入粗大的下腔静脉，它扩大了介入性门腔分流的适应症，可使部分难以实施TIPS术的患者也能做介入性门腔分流，成为介入性门腔分流的新热点。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
