[Small bowel stenoses as a consequence of intrauterine transfusion (author's transl)].

An infant is reported who, because of Rhesus incompatibility, required 4 antenatal blood transfusions. At the last of these transfusions performed during the 30th week of pregnancy, the catheter could not be removed and was left in the foetus's abdomen. Two weeks later, spontaneous delivery of an 1820 gm. male infant resulted. He had to be operated on on the 2nd day of life because of small bowel atresia, which was caused by two severe intestinal strictures which had been produced by the catheter. Following removal of the catheter and resection of the strictures, the post-operative course was essentially uneventful.
