생체 공여신 100례: 다발성 신동맥 공여신을 중심으로

Abstract

One hundred kidney transplantations have been performed between November 1982 and July 1989. Twenty-seven patients received kidneys from living donors with multiple renal arteries. In eighteen patients both vessels were anastomosed, and in nine patients: a tiny polar vessel was sacrificed resulting in a small infarct in the grafted kidney. Results of transplantation in these patients were compared to those of recipients with or without infarcted kidney in regard to time, sex and age. Results using kidneys with anastomosed double renal arteries without infarct were almost as successful as those from a living donor with single renal arteries( well function kidney, serum creatinine <2.0mg/dl:70%). In contrast, recipients of kidneys with polar infarcts appear to have undergone more episodes of acute tubular necrosis, hypertension, or both(well function kidney :25%). Therefore, living donor with bilateral double renal arteries should be regarded as acceptable donor if both vessels can easily be anastomosed. If, however, a polar vessel has to be sacrificed. it is suggested that related living donor with polar artery should be excluded.
