The Vascular Surgery Research Group KI SÖS
SOSVASC is an active Clinical Research group with around 15 members in Vascular Surgery, Trauma, Wound care, and Nursing Research. In addition to collaborations within KI SÖS, we have established collaborations with other groups at KI, as well as with external universities both nationally and internationally.
