Description

Invenţia se referă la medicină, în special la hemostaza endoscopică a hemoragiilor din varice esofago-gastrice în caz de ciroză hepatică. The invention relates to medicine, in particular to endoscopic hemostasis of bleeding from esophageal-gastric varices in case of liver cirrhosis.

Este cunoscută metoda de hemostază cu utilizarea adezivului fibrinic, care constă din fibrinogen, factorul XIII de coagulare, fibronectin, plasminogen şi aprotinin, care se amestecă cu soluţie de trombină şi clorură de Ca+2, în următorul raport al componentelor în 1 ml: The hemostasis method using fibrin glue is known, which consists of fibrinogen, coagulation factor XIII, fibronectin, plasminogen and aprotinin, which are mixed with thrombin and Ca+2 chloride solution, in the following ratio of components in 1 ml:

fibrinogen (mg) 70...110 factorul XIII de coagulare (U) 10...50 fibronectin (mg) 2...9 plasminogen (µg) 20...120 aprotinin (KIU) 3000 trombină (UI) 500 clorură de Ca+2 (µmol) 40 [1].fibrinogen (mg) 70...110 coagulation factor XIII (U) 10...50 fibronectin (mg) 2...9 plasminogen (µg) 20...120 aprotinin (KIU) 3000 thrombin (UI) 500 Ca+2 chloride (µmol) 40 [1].

Dezavantajul metodei cunoscute constă în aceea că polimerizarea adezivului fibrinic are loc imediat după combinarea componentelor, ceea ce nu permite introducerea prin cateter în lumenul varicelui care sângerează. The disadvantage of the known method is that the polymerization of the fibrin glue occurs immediately after combining the components, which does not allow for catheter insertion into the lumen of the bleeding variceal vein.

Este cunoscută utilizarea soluţiei alcoolice de tetradecil sulfat de sodiu pentru hemostaza endoscopică a hemoragiilor variceale cirogene, care provoacă sclerozarea vasului [2]. The use of alcoholic sodium tetradecyl sulfate solution for endoscopic hemostasis of cicatricial variceal hemorrhages, which causes vessel sclerosis, is known [2].

Dezavantajul constă în ineficacitatea utilizării ei în cazul varicelor de calibru mare, provoacă dureri pronunţate, după utilizarea ei provoacă în unele cazuri necroze locale cu complicaţii severe, şi anume perforaţii ale esofagului, mediastinite. The disadvantage is that it is ineffective in the case of large varicose veins, it causes severe pain, and after use, in some cases it causes local necrosis with severe complications, namely perforation of the esophagus, mediastinitis.

Este cunoscută metoda de hemostază endoscopică a hemoragiilor variceale esofagiene cirogene cu injectarea în lumenul varicelor sângerânde a adezivului fibrinic, care constă din soluţie de fibrinogen, care se amestecă cu soluţii de aprotinin, trombină şi clorură de Ca+2 şi adrenalină, în următorul raport al componentelor în 1 ml: The method of endoscopic hemostasis of surgical esophageal variceal hemorrhages is known with the injection into the lumen of the bleeding varices of fibrin glue, which consists of a fibrinogen solution, which is mixed with solutions of aprotinin, thrombin and Ca+2 chloride and adrenaline, in the following ratio of components in 1 ml:

sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. trombină (UI) 25...100 sol. clorură de Ca+2 (µmol) 15...30 sol. adrenalină (mg) 0,1…0,3 [3]. sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. thrombin (UI) 25...100 sol. Ca+2 chloride (µmol) 15...30 sol. adrenaline (mg) 0.1...0.3 [3].

Dezavantajele metodei cunoscute constau în apariţia complicaţiilor septice cauzate de translocarea bacteriană în timpul injectării, totodată eficacitatea umplerii lumenului variceal cu adezivul fibrinic este dificil de stabilit, ceea ce poate duce la o umplere incompletă cu persistarea unor segmente de varice neblocate, care pot fi cauza unor hemoragii repetate. The disadvantages of the known method are the occurrence of septic complications caused by bacterial translocation during injection, while the effectiveness of filling the varicose lumen with fibrin glue is difficult to establish, which can lead to incomplete filling with the persistence of unblocked varicose vein segments, which can be the cause of repeated hemorrhages.

Problema invenţiei constă în elaborarea unei metode de hemostază endoscopică a hemoragiilor esofagiene cu injectarea intravariceală a unui adeziv fibrinic, care permite vizualizarea clară a eficacităţii umplerii tuturor ramurilor variceale cu profilaxia recidivelor hemoragice şi ale complicaţiilor septice posibile cauzate de translocarea bacteriană. The problem of the invention consists in developing a method of endoscopic hemostasis of esophageal hemorrhages with intravariceal injection of a fibrin glue, which allows clear visualization of the effectiveness of filling all varicose branches with prophylaxis of hemorrhagic relapses and possible septic complications caused by bacterial translocation.

Esenţa invenţiei constă în injectarea în lumenul varicelor sângerânde a unui adeziv fibrinic, care conţine soluţie de fibrinogen, care se amestecă cu soluţii de aprotinin, trombină şi clorură de Ca+2 în următorul raport al componentelor în 1 ml: The essence of the invention consists in injecting into the lumen of bleeding varicose veins a fibrin adhesive containing fibrinogen solution, which is mixed with solutions of aprotinin, thrombin and Ca+2 chloride in the following ratio of components in 1 ml:

sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. trombină (UI) 25...100 sol. clorură de Ca+2 (µmol) 15...30,sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. thrombin (UI) 25...100 sol. Ca+2 chloride (µmol) 15...30,

unde trombina se dizolvă în 5...20 ml de soluţie de metronidazol cu concentraţia de 5 mg/ml, la care se adaugă soluţiile de aprotinin şi clorură de Ca+2, iar în soluţia de fibrinogen se adaugă 1 ml de colorant Trypan Blue cu concentraţia de 0,6 mg/ml, după care componentele se injectează separat cu polimerizarea definitivă în lumenul varicelui. where thrombin is dissolved in 5...20 ml of metronidazole solution with a concentration of 5 mg/ml, to which the aprotinin and Ca+2 chloride solutions are added, and 1 ml of Trypan Blue dye with a concentration of 0.6 mg/ml is added to the fibrinogen solution, after which the components are injected separately with final polymerization into the lumen of the varicose vein.

Rezultatul invenţiei constă în hemostaza endoscopică eficientă a hemoragiilor esofagiene cu injectarea intravariceală a unui adeziv fibrinic, care permite vizualizarea clară a eficacităţii umplerii tuturor ramurilor variceale cu profilaxia recidivelor hemoragice şi ale complicaţiilor septice posibile cauzate de translocarea bacteriană. The result of the invention consists in the effective endoscopic hemostasis of esophageal hemorrhages with intravariceal injection of a fibrin glue, which allows clear visualization of the effectiveness of filling all varicose branches with the prophylaxis of hemorrhagic relapses and possible septic complications caused by bacterial translocation.

Adezivul fibrinic se prepară din două componente, şi anume se combină soluţie de fibrinogen cu soluţii de aprotinin, trombină şi clorură de Ca+2, în cantităţile indicate: Fibrin glue is prepared from two components, namely combining fibrinogen solution with solutions of aprotinin, thrombin and Ca+2 chloride, in the indicated quantities:

sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. trombină (UI) 25...100 sol. clorură de Ca+2 (µmol) 15...30,sol. fibrinogen (mg) 15...30 sol. aprotinin (KIU) 250...1000 sol. thrombin (UI) 25...100 sol. Ca+2 chloride (µmol) 15...30,

Trombina se dizolvă în 5...20 ml de metronidazol cu concentraţia de 5 mg/ml, la care se adaugă soluţiile de aprotinin şi clorură de Ca+2, iar în soluţia de fibrinogen se adaugă 1 ml de colorant Trypan Blue cu concentraţia de 0,6 mg/ml, dupa care componentele se injectează separat cu polimerizarea definitivă în lumenul varicelui. Thrombin is dissolved in 5...20 ml of metronidazole with a concentration of 5 mg/ml, to which the solutions of aprotinin and Ca+2 chloride are added, and 1 ml of Trypan Blue dye with a concentration of 0.6 mg/ml is added to the fibrinogen solution, after which the components are injected separately with final polymerization into the lumen of the varicose vein.

Soluţia de fibrinogen se aspiră într-o seringă şi celelalte componente în combinaţie în altă seringă, care se injectează separat printr-un cateter trifurcat la capătul proximal. În interiorul cateterului ambele componente se combingă, unde începe procesul de polimerizare, care nimerind în interiorul varicelui are loc finisarea procesului de polimerizare cu formarea cheagului fibrinic colorat stabil şi o vizualizare a umplerii eficiente a tuturor ramurilor variceale. The fibrinogen solution is drawn into a syringe and the other components in combination into another syringe, which are injected separately through a trifurcated catheter at the proximal end. Inside the catheter, both components are combined, where the polymerization process begins, which, reaching the inside of the varicose vein, completes the polymerization process with the formation of a stable colored fibrin clot and a visualization of the effective filling of all varicose branches.

Colorantul Trypan Blue cu concentraţia de 0,6 mg/ml cu formula (4,4'-bis(1-hidroxi-8-amino-3,6-disulfonaftalinazo)-3,3'-dimetilbifeniladisodiu cu formula chimică C34H24N6Na4O14S4, colorant utilizat pentru colorarea selectivă a celulelor tisulare.
