    Notes: Summary A method was applied in anesthetized dogs enabling the measurement of regional resistances up to and behind the start of collaterals and the collateral resistance. The studies show that peripheral coronary pressure, i.e. perfusion pressure of the collaterals, can change when the ratio of pre- and post-collateral resistance alters. Drugs can influence collateral blood flow not only by directly effecting the collaterals but also by altering collateral perfusion pressure. Glyceryl trinitrate given in minor doses improved collateral blood flow by directly dilating the collaterals and also by increasing collateral perfusion pressure. Higher doses did not improve collateral flow due to a decrease of collateral perfusion pressure. A stealphenomenon occurred in some cases. Adenosine and verapamil had no direct influence on the collateral resistance. Verapamil given in small doses increased perfusion pressure slightly but not enough to improve collateral blood flow. High doses of verapamil, like low doses of adenosine, had no significant influence on collateral perfusion pressure and collateral blood flow. Adenosine given in high dosage led to a diminution of collateral flow by decreasing collateral perfusion pressure, i.e. a steal-phenomenon.

    Description / Table of Contents: Summary We report on two cases of acute knee trauma with rupture of the synovial tissue of the anterior cruciate ligament. The femoral part of the synovia had retracted and was locked between the femoral attachment of the anterior cruciate ligament and the femur condyle. Both patients showed clinical signs of an acute lesion of the medial meniscus with loss of extension and tenderness on palpation over the medial joint cavity. After complete arthroscopic resection of the interfered soft tissue, both patients had full range of motion and no signs of any knee discomfort.
    Notes: Zusammenfassung Wir berichten über 2 Fälle eines traumatischen Einrisses des Synoviaüberzugs über dem vorderen Kreuzband nach Kniegelenkverdrehtrauma. Der femorale Anteil der Synovia retrahierte sich und klemmte zwischen dem femoralen Ansatz des vorderen Kreuzbands und der Femurkondyle im Sinne eines Impingements mit schmerzbedingter Streckhemmung ein. Klinisch imponierte der Befund wie eine akute Meniskuseinklemmung. Arthroskopisch wurden eine Meniskusläsion ausgeschlossen und die eingeschlagenen Weichteile entfernt. Bei sofort postoperativ wiedererlangter schmerzfreier Beweglichkeit blieben die Patienten beschwerdefrei.
