门静脉

Objective To study the effect on liver hemodynamics of portal arterialization and complete shunt, splenorenal shut and peripheral cardia divided vessel.

目的 观察门静脉动脉化+完全门体分流术和传统的脾肾分流术及贲门周围血管离断术对门静脉血流动力学的影响。

After 5-day common bile duct ligation, reopening and portal vein arterialization for 1 month, the hepatic blood flow and portal venous pressure had no significant difference from those of normal controls.

胆总管结扎5 d后的大鼠行胆管再通+门静脉动脉化手术后1 mo，肝脏血流量和门静脉压与正常组比较无显著差异。

Methods A retrospective analysis was carried out in 245 cases with portal hypertension treated with PCDV or PSRS plus PCDV. The diameter, blood flow velocity and blood flow of portal vein, splenic vein and superior mesenteric vein were measured by magnetic resonance angiograph at 1 week preoperatively and at 2 week postoperatively.

回顾性总结近8年采用脾肾分流加门奇断流联合手术和门奇断流术治疗门静脉高压症245例，于术前一周和术后2周应用核磁共振血管造影测量门静脉、脾静脉和肠系膜上静脉的直径，流速和流量，并于术中动态测量门静脉压力。

ABSTRACT: BACKGROUND: Liver transplantation in presence of diffuse portal vein thrombosis is possible by using caval blood as portal inflow, through cavo-portal transposition.

背景：目前在应用肝移植治疗弥漫性门静脉血栓通常是通过下腔静脉-门静脉转流将下腔静脉血分流至门静脉。

Methods: For 56 cases of arterial bleeding, performed angiography in the artery which was suspected to be the bleeding one, and then infused the embolus into the bleeding after super-selection to embolize it. For 17 cases of esophageal veins and fundic veins bleeding caused by the higher blood pressure in portal vein, we performed angiography in portal vein stem through puncturing the liver, found the bleeding spot, then infuse the embolus into the bleeding veins through super-selection to stop bleeding.

56例动脉性出血采用Seldinger氏法，经股动脉穿刺将导管选择插入可疑出血的动脉内先行DSA检查，明确诊断，再超选择插入出血动脉内注入栓塞材料，栓塞出血动脉。17例门静脉高压致食管胃底静脉曲张破裂出血，则采用经皮穿肝至门静脉主干行门静脉造影，明确出血部位，再超选择插管至出血静脉注入栓塞材料进行栓塞治疗。

Portal vein pressure, size of spleen the collateral circulation of portal vein and the fluctuation of hematocyte counts were measured and recorded at the preconcerted time.

实验犬25只，随机分为A组(正常组，n=5)、B组(对照组，n=10)、C组(实验组，n=10)。A组仅予以剖腹探查，B组予以门静脉主干部分结扎建立模型，C组则通过门静脉主干部分结扎附加3周后脾静脉缩窄及其属支结扎的方法建立模型，建模后术前及术后每周动态观察两组动物血象的变化，B、C组在预定时间点(术后第5、第9周)分别随机选择5只动物开腹观测门静脉自由压、脾脏大小、门体侧支循环形成情况，并切取脾脏行组织病理学检查，此外，术前及术后预定时间点了解骨髓增生情况变化。

Objective To sum up the etiology and the experience on diagnosis and treatment for pancreatogenic portal hypertension complicated with hemorrhage of upper digestive tract in severe acute pancreatitis.

胰源性门静脉高压症是一种因脾静脉回流受阻所致的&区域性门静脉高压症&，在重症急性胰腺炎后期合并消化道出血中，胰源性门静脉高压是较少见和容易忽视的病因。

Results:The characteristic features included loss of the normal architecture of the portal system and the presence of multiple,sinuous,periportal vascular structures which were enhanced during the portal phase.

结果：主要CT表现为门静脉走行区结构紊乱，正常结构消失；在门静脉走行区出现血管或迂曲、扩张窦隙样血管结构，其在门静脉期明显强化。

Results:(1) All of HCC were irregular hyperdense in arterial phase companioned with mass and hyperdense tumor vessels.

结果 ：( 1)肝动脉期肿瘤实质出现密度高于肝实质的肿瘤血管和瘤区强化，门静脉期其密度迅速降低，至平衡期为低密度；( 2 )肿瘤边缘于肝动脉期和门静脉期均可见环行强化；( 3)转移性子灶仅在肝动脉期明显强化，门脉期全瘤密度迅速降至等密度；( 4)门静脉受累表现为肝内分支的边缘侵蚀、破坏、中断，或为不规则的充盈缺损。

The PVA without limiting the blood flow volume can increase the cross section and blood flow volume of portal vein ,dilate and thicken the branches of portal vein, but the function of reticuloendothelial system, metabolism of bile pigment and bile acid salt don′t undergo significant influences.

未采取限流措施的门静脉动脉化可导致门静脉横截面积和血流量增加，门静脉分支扩张、管壁增厚，但网状内皮系统的吞噬功能以及胆色素和胆盐的代谢未受显著的影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
