title: [Histomorphological findings in the ascending aorta and inferior vena cava following implantation of ultrasonic Doppler flow transducers and pressure transducers in long-term experiments with rabbits and cats].
abstract: We investigated the histological changes of the vessel walls of the carotis dextra, the aorta ascendens and the vena cava inferior following implantation of flow- and pressuretransducers of 17 rabbits and 4 cats. Following correct adaptation of the vessel volumen the implantates were all well tolerated over a prolonged period (up to 58 weeks) and encapsulated by connective tissue. The histological processes are descripted in detail and lesions produced by ultrasound are shown.
