[Arthrocele as a cause of phlebothrombosis]

Report on an extended thrombosis of the lower leg and the femur in which after a successless ambulatory treatment of one year an arthrocele of the knee-joint of the size of a fist could be proved. After operative removal of it a clinical regression of all symptoms of phlebothrombosis over a period of 2 years was observed. It is recommended to observe increasingly the in no case rare arthroceles in the thromboses of the lower extremities and if the occasion arises to include their operative treatment in the therapeutic considerations.
