腔内超声 meaning in Chinese
endo-luminal ultrasound
Examples
- Application of trus in diagnosis of colon and rectum disease
经直肠腔内超声在肛肠病变诊断上的应用 - Intraluminal ultrasonic imaging
管腔内超声显像 - Aim to evaluate the feasibility of one simple method to establish model of venous thrombosis for studying the therapeutic effect of intracavitary ultrasonic therapy on venous thrombus of animal models . methods the lower limbs of 20 dogs were divided randomly into the experimental group and the control group . the femoral veins of the experimental group were ligated at the close and distant end respectively to slower the flow of blood . the veins in control group were operated but not ligated . then , the changes of the dogs ' lower limbs were observed and the femoral veins were excised for pathological examinations and examined to investigate the condition of thrombis in the veins at the 1st , 4th and 7th day respectively after operation . results all the dog ' s lower limbs in the experimental group swelled and were lame slightly , the thrombus came forth in all the 6 veins by pathologic study at the 1st day after operation . and it was opposite in the control group . in addition , the swelling of all the dogs ' lower limbs was aggravated and all the 14 femoral veins were filled with compact mixed thrombus at the 4th and 7th day after operation . and it was also opposite in the control group . conclusion the method to establish models of venous thrombosis by the simple ligation of close and distant end of the femoral veins can make thrombosis more approaching clinical course of thrombosis and is satisfying
目的为研究腔内超声溶栓对动物模型静脉血栓的疗效而评价一种制备静脉血栓模型方法的可行性.方法犬20只采用自身对照研究,犬一侧后肢股静脉为实验侧,另一侧为对照侧.实验侧行股静脉近、远端分别结扎,人为造成犬后肢股静脉血流缓慢;对照侧行手术,但不结扎血管.然后于术后第1 , 4 , 7天分别观察犬后肢变化,切取血管标本做病理观察,了解血栓形成情况.结果术后第1天实验侧全部出现后肢肿胀,轻微跛行,病理切片显示: 6条静脉全部都形成血栓;对照侧没有出现后肢肿胀及跛行, 6条静脉都无血栓形成.第4 , 7天实验侧后肢肿胀加重,跛行,病理切片显示:实验侧14条静脉血栓充满管腔,为混和血栓;对照侧没有出现后肢肿胀及跛行, 14条静脉无血栓形成.结论采用静脉单纯结扎法制备犬静脉血栓模型,血栓形成更接近临床血栓形成过程
