Surgeons at Prague’s Institute for Clinical and Experimental Medicine (IKEM) performed the first ever six-way paired kidney transplant in the Czech Republic on Tuesday and Wednesday. Six patients in need of a kidney received them from six donors. The so-called “six-way domino” surgery relies on the fact that someone who is close to a transplant patient but is not a match offers his or her kidney to another patient, and six such pairs form a donor chain.
