Однако, создание временного шунта между нижней полой веной ниже печённых вен и одной из вен портальной системы может привести к воздушной эмболии и кровотечению.However, creating a temporary shunt between the inferior vena cava below the liver veins and one of the veins of the portal system can lead to air embolism and bleeding.

Целью настоящего изобретения является предупреждение воздушной эмболии и кровотечение.An object of the present invention is to prevent air embolism and bleeding.

Для этого- портокавальный шунт накладывают между тонкокишечной веной и основной веной предплечья.For this, a portocaval shunt is placed between the small intestine vein and the main vein of the forearm.

Способ получения модели сухой пе— jq чени осуществляют следующим образом»The method of obtaining a model of dry hemp jq is as follows "

Животному, например собаке дают морфингексеналовый наркоз. Производят серединную лапаротомию, в рану выводя тонкую кишку, на брыжейке выбирают одну из веточек тонкокишечной вены, наиболее пригодную для канюлирования. Под вену проводят три держалки. После этого обнажают подкожную вену.Предплечья, где под участок ее, наиболее пригодный для канюлирования, подводят три шелковые держалки. Затем одновременно двумя бригадами хирургов проводят канюлирование. Канюлю вводят в тонкокишечную вену по ходу оттока крови от кишечника; канюлю фиксируют, например, двумя лигатурами, тр етью лигатуру накладывают на дисталь— ный отдел вены. Другую канюлк>вводят в подкожную вену предплечья по току крови в ней; вторую канюлю фиксируют двумя лигатурами, третью лигатуру накладывают на дистальный конец вены. Сразу после канюлирования производят пережатие ПДС эластическим зажимом с резиновыми трубками на браншах. Сдновременно с затягиванием лигатур начинают дозированное ведение антикоагулянтов через катетер в начале кровотока по шунту.An animal, such as a dog, is given morphinghexenal anesthesia. A mid laparotomy is performed, removing the small intestine into the wound, and one of the branches of the small intestine vein that is most suitable for cannulation is selected on the mesentery. Under the vein spend three holders. After this, the saphenous vein is exposed. The forearms, where three silk holders are brought under the area most suitable for cannulation. Then simultaneously, two teams of surgeons carry out cannulation. The cannula is injected into the small intestine vein along the outflow of blood from the intestine; The cannula is fixed, for example, with two ligatures, three ligatures are placed on the distal vein. Another cannula> is injected into the saphenous vein of the forearm by the blood flow in it; the second cannula is fixed with two ligatures, the third ligature is applied to the distal end of the vein. Immediately after cannulation, the PDS is clamped with an elastic clamp with rubber tubes on the branches. Simultaneously with the tightening of the ligatures, dosed administration of anticoagulants through a catheter at the beginning of blood flow through a shunt begins.

Наложение шунта между основной веной предплечья и тонкокишечнсй веной упрощает техническое выполнение способа.The application of a shunt between the main vein of the forearm and the small intestine vein simplifies the technical implementation of the method.

Сброс портальной крови происходит в систему верхней полой вены без вскрытия крупных сосудов, что позволяет предотвратить кровотечение и воздушную эмболию во Еремя Вскрытия просвета. Обеспечение этих условий позволяет использовать модель 'сухой печени' в клинической хирургии;Portal blood is discharged into the system of the superior vena cava without opening large vessels, which helps prevent bleeding and air embolism during the opening of the lumen. Providing these conditions allows the use of the 'dry liver' model in clinical surgery;

Claims

This invention relates to medicine and is used in surgical hepatology. A known method for obtaining a model of a dry liver by pressing the hepatic artery, followed by vn / triven ™ administration of anticoagulants and the application of a portocaval shuntS. However, the creation of a temporary shunt between the inferior vena cava below the hepatic veins and one of the veins of the portal system can lead to an air embolism and bleeding. The purpose of the present invention is to prevent air embolism and bleeding. To do this, the portocaval shunt is inserted between the small intestinal vein and the main vein of the forearm. The method for producing a dry liver model is carried out as follows. An animal, such as a dog, is given morphinexenal anesthesia. A mid-laparotomy is performed, the small intestine is removed into the wound, and one of the branches of the small intestinal vein most suitable for cannula is inserted into the mesentery. Three handles are held under the vein. After that, iodine vein is applied. The forearm, where, under the area most suitable for cannulated, three silk handles are fed. Then, two teams of surgeons were simultaneously cannulated. The cannula is inserted into the small-vein vein along the outflow of blood from the keel bone; the cannula is fixed, for example with two ligatures, with a ligature the ligature is placed on the distal vein. Another cannula is inserted into the saphenous vein by the forearm through the blood flow in it; the second cannula is fixed with two ligatures, the third ligature is applied to the distal end of the vein. Immediately after cannulation, the PDS was clamped with an elastic clip with rubber tubes on the branches. Simultaneously with the tightening of the ligatures, the dosing of anticoagulants is started through the catheter at the beginning of the blood flow through the shunt. 3 73 The imposition of a shunt between the main vein of the forearm and the small-cumulative vein simplifies the technical expansion of the method. Portal blood discharge occurs. Both of these conditions allow the use of the dry liver model in clinical surgery; The invention The method of obtaining a model of the liver ear by clamping the hepatic artery, 74, followed by intravenous administration of anticoagulants and the application of a portal caval shunt, is characterized in that, in order to prevent airway embolism and bleeding, the portal saccelement strait is placed between the small ventricular venous ventricle and the bleeding vein.
