In an experimental model, autologous vein grafts, autolog and heterolog lyophilized vein grafts, and Gore-Tex prostheses were interposed in the femoral artery. The functional result was checked by transvenous xeroarteriography. Results: Thus far, independent of their length, autologous vein grafts have a success rate similar to that of direct microvascular(More)
Durch weitgehende Simulierung klinischer Verhältnisse wird in experimentellen Untersuchungen versucht, Einblick in die Pathomechanismen des posttraumatischen Geschehens zu erhalten. Nach standardisierter, einseitiger, geschlossener Extremitätenfraktur bei Kaninchen, sind partikuläres Fett und Knochenmarkselemente in der Lungenstrombahn nachweisbar. Diese(More)
During coagulation at vascular pedicle flaps by means of unipolar diathermy the high-frequency current passes from the actual site of coagulation to the neutral electrode outside the flap, thus running through the nutrient vessels. This means that at higher amperages the nutrient vessels could suffer irreversible damage, as the current reaches its highest(More)
In a series of experiments, enterotomies on 180 rats were closed by suture (Lembert) and by suture in combination with plasma fractions with and without fibrinolytic inhibitors. After fixed intervals, a section of the small colon was dissected and tensile strength was measured. In addition, micromorphologic and histochemical studies were performed. The(More)
Experimental investigations were carried out to correlate posttraumatic leukocyte infiltration of lung interstitium and edema formation. From human leukocyte lysosomes, four different neutral proteinases could be extracted and characterized by means of their specific substrates and their inhibitor spectra. Granulocyte kininogenase was sensitive to(More)
Patients with polytrauma (n = 45) in acute renal failure were hemodialyzed (n = 472) using minimal heparinization in order to avoid bleeding complications, and were surpervised by the activated partial thromboplastin time (Vogel and Kopp). According to our investigations of coagulation factors, antithrombin III, fibrinolytic system, platelets, and(More)
The purpose of this brief outline is to give an insight into the nature of our Institute as a connecting link between different branches of medicine and to indicate the variety of new technical equipment used. Diese kurzgefaßten Ausführungen sollen einen kleinen Einblick in den interdisziplinären Charakter unseres Institutes geben und auf die Vielfalt neuer(More)
Severe cartilage defects of the load area were repaired by autologous cartilage grafts with subchondral bone. The intact cartilage graft with subchondral bone was drilled mainly from the proximal, nonload area of the femoral condyl. The joint lesion area was drilled by the same technique, the grafts were transported and fixed by fibrin adhesion. The results(More)
Bei der Zerstörung von Hirngewebe und Blutasutritt in die Liquorräume als Folge eines Schädel-Hirntraumas kommt es zur Freisetzung von Polypeptiden des Kininsystems. systems. Diese biologisch hochaktiven Substanzen führen einerseits durch Reizung der intrathekalen neurovaskulären Strukturen zum klinischen Bild einer meningealen Reizung und zu(More)
