目的 介绍下腔静脉造影指示下犬房间隔穿刺术方法。方法 对9只健康杂种犬进行了下腔静脉造影指示下的房间隔穿刺术。全麻下经皮穿刺右侧股静脉,X线投照角度RAO 30°,经Mullins鞘管注射76 %的泛影葡胺2 0mL行下腔静脉造影,分别显示下腔静脉及其开口、右心房影、左心房影和主动脉根部影,将Brockenbrough穿刺针远端弯度的近端塑形增加1个弯度,使穿刺针方向指示器指向3点左右、针尖顶至房间隔进行穿刺。结果 ( 1 )下腔静脉造影显示与房间隔穿刺有关的解剖特征为下腔静脉开口位置高,全部在房间隔中上部,使房间隔穿刺点位置也高,加上左心房腔小,穿刺针易穿至左心房顶部;( 2 )下腔静脉造影指导下房间隔穿刺术成功率为1 0 0 % ( 9/ 9) ,心脏压塞1例,经X线和造影剂指示心包穿刺引流术控制。结论 下腔静脉造影指导下的经皮犬房间隔穿刺术简单易行。
Objective To introduce the method of atrial septal puncture under the guidance of inferior vena cava angiography. Methods 9 healthy mongrel dogs underwent ventricle puncture under the guidance of inferior vena cava angiography. Under general anesthesia percutaneous puncture of the right femoral vein, X-ray projection angle RAO 30 °, 76% of the Mullins sheath injection of diazepam 200mL inferior vena cava angiography, showing the inferior vena cava and its opening, respectively, the right Atrial shadow, left atrial shadow and aortic root shadow, the proximal curve of the Brockenbrough needle distal curvature of the plastic increased by 1 degree of curvature, so that the puncture needle direction indicator points to about 3:00, the top of the needle atrial septal puncture. Results (1) Inferior vena cava angiography showed atrial septal puncture-related anatomical features of the location of the opening of the inferior vena cava, all in the upper part of the atrial septum, so that atrial septal puncture point position is also high, with a small left atrial cavity, the needle Easy to wear to the top of the left atrium; (2) under the guidance of inferior vena cava angiography atrial septal puncture success rate was 100% (9/9), cardiac tamponade in 1 case, by X-ray and contrast agent pericardiocentesis control. Conclusion Percutaneous canine atrial septal puncture guided by inferior vena cava angiography is simple and easy.
