Zweck : Der Zweck ist einen Gefäßteiiabschnitt zwischen den beiden Ballons während des chirurgischen Eingriffes vorübergehend auszuschalten unter Beibehaltung des arteriellen bzw. venösen Blutflusses durch den Katheterhohlraum. Dadurch wird Biuttrockenheit im betreffenden Operationsgebiet erreicht, Zeit für den operativen Eingriff gewonnen und eine hämatogene Ausschwemmung von Carcinomzellen verhindert.Purpose: The purpose is a section of vessel between the two Temporarily turn off balloons during surgery while maintaining the arterial or venous blood flow through the catheter lumen. This will Bone dryness reached in the operating area concerned, time for the operative one Surgery won and a hematogenous washout of carcinoma cells prevented.
Stand der Technik und Kritik Es ist bekannt, dass z.B. bei Eingriffen an der Leber intraluminäre Katheter verwendet werden, die entweder über das rechte Herzohr ( T.Schrock et al.in Arch.Surg.State of the art and criticism It is known that, for example, during interventions Intraluminal catheters can be used on the liver, either through the right Herzohr (T.Schrock et al. In Arch.Surg.
#Vol.96.May 1968, 698-704 ) oder über die untere Hohlvene eingebracht werden ( F.Fekete et R.Parc in Ann.# Vol.96.May 1968, 698-704) or introduced via the inferior vena cava (F. Fekete et R. Parc in Ann.
Chir. 1973. 27,8pp,793-802 ). Der Nachteil beim Einbringen eines intraluminären Katheters über das rechte Herzohr ist die notwendige Eröffnung von Bauch- und Brusthöhle verbunden mit der schwierigen Technik, des Zeitaufwandes und der erhöhten intra- und postoperativen Komplikationsrate. Der Nachteil bei Einbringen eines intraluminären Katheters über die untere Hohlvene ist das schwierige und zeitaufwendige Aufsuchen der unteren Hohlvene bei leichter Verletzbarkeit und erhöhter Schwierigkeit der nachfolgenden Gefäßrekonstruktion. Über die Anwendung intraluminärer Katheter bei Eingriffen an den großen Bauchgefäßen, bei en-bloc Transplantationen von Magen, Pankreas, Leber und Darm und bei Nieren- und Dickdarmtumoren ist in der Fachliteratur nichts bekannt.Chir. 1973. 27.8 pp, 793-802). The disadvantage of introducing an intraluminal Catheter through the right atrial appendage is the necessary opening of the abdominal and thoracic cavity combined with the difficult technology, the time required and the increased intra- and postoperative complication rate. The disadvantage of introducing an intraluminal Catheter via the inferior vena cava is difficult and time-consuming to locate of the inferior vena cava with slight vulnerability and increased difficulty the subsequent vascular reconstruction. About the use of intraluminal catheters for operations on the large abdominal vessels, for en bloc transplants of the stomach, The pancreas, liver and intestines and in kidney and colon tumors is in the specialist literature nothing known.
Aufgabe Der Erfindung liegt die Aufgabe zugrunde chirurgische Eingriffe an der Leber, an den großen Bauchgefäßen und bei en-bloc Transplantationen von Magen, Pankreas, Leber und Darm zu vereinfachen und die hämatogene Ausschwemmung von Carcinomzellen während der Operation an Nieren- und Dickdarmtumoren zu verhindern.OBJECT The invention is based on the object of surgical interventions on the liver, on the large abdominal vessels and in en bloc transplants of the stomach, Simplify the pancreas, liver and intestines and the hematogenous flushing of carcinoma cells to prevent kidney and colon tumors during surgery.

hepatoduodenale verlaufenden Arteria hepatica propria und Vena portae, der Blutabfluss aus der Leber über die Venae hepaticae in die Vena cava inferior.hepatoduodenal arteria hepatica propria and vena portae, the outflow of blood from the liver via the hepatic veins into the inferior vena cava.
Bei einer peripheren und insbesondere zentralen Leberruptur kommt es zu einer massiven Blutung aus dem arteriellen, aus dem Pfortder- und aus dem venösen System. Das arterielle und das Pfortadersystem können über eine vorübergehende Unterbindung des lig.hepatoduodenale blockiert werden. Wegen der Unbeeinflussbarkeit des venösen Rückflusses aus der Vena cava inferior über die Venae hepaticae ist eine zur Blutstillung notwendige kurzdauernde Bluttrockenheit nicht möglich. Neben später auftretenden Gerinnungsstörungen ist dies die Hauptursache der hohen postoperativen Letalitätsquote.In the case of a peripheral and especially central liver rupture there is massive bleeding from the arterial, from the portal and from the venous system. The arterial and portal systems can have a transient Ligation of the hepatoduodenal ligament is blocked. Because of the fact that it cannot be influenced of venous return from the inferior vena cava via the hepatic veins a short-term dryness of the blood necessary for hemostasis is not possible. Next to later occurring coagulation disorders this is the main cause of the high postoperative Mortality rate.
Der intraluminäre Doppelballonkatheter wird über eine freipräparierte und eröffnete Vena femoralis eingebracht. Unter Bildwandlerkontrolle der Kontrastmittelstreifen ( E ) und unter Beachtung der Längenmarkierung (-F ) wird der eigentliche Katheter ( A ) derart in der ~Vena cava inferior unterhalb oder in Höhe des Zwerchfells lokalisiert, dass die in die Vena cava inferior einmündenden Venae hepaticae zwischen die beiden Katheterballons ( B 1 und B 2 ) zu liegen kommen. Über den Zuleitungsschlauch ( C 1 ) werden die beiden Katheterballons aufgeblasen und mit Hilfe des Kontrollballons ( D ) auf Intaktheit und Spannung kontrolliert. Gleichzeitig werden durch temporäre Ligierung des lig. hepatoduodenale das arterielle und das Pfortadersystem blockiert. Folglich ist einerseits der venöse Rückfluss aus der Vena cava inferior und andererseits der Zufluss aus der Arteria hepatica propria und der Pfortader unterbrochen und damit eine für die definitive Blutstillung notwendige, vorübergehende Bluttrockenheit gegeben.The intraluminal double balloon catheter is placed over a freely dissected and inserted the opened femoral vein. The contrast medium strips under the control of the image converter (E) and taking into account the length marking (-F) the actual catheter (A) located in the inferior vena cava below or at the level of the diaphragm, that the hepatic veins, which open into the inferior vena cava, are between the two Catheter balloons (B 1 and B 2) come to rest. Via the supply hose ( C 1) the two catheter balloons are inflated and with the help of the control balloon (D) Checked for integrity and tension. At the same time through temporary Ligation of the lig. hepatoduodenale blocks the arterial and portal vein systems. Consequently, on the one hand the venous return flow from the vena cava is inferior and on the other hand the inflow from the arteria hepatica propria and the Portal vein interrupted and with it a temporary blood dryness necessary for the definitive hemostasis given.
