The aim of this study is to retrospectively evaluate the complications, safety and accuracy of midtrimester amniocentesis (MTAcz) in multiple pregnancy (MP). The indications and complications of MTAcz are the same for singleton pregnancies (SP) and MP, but what's different is the technique of the procedure and frequency of complications. Various techniques are here quoted, the purpose of which is to prove that samples have been taken from separate sacs. In general, the efficacy in amniotic fluid collection is 92–98%, and 95.6% in autors' cases. The number of insertion needles may have the influence on the abortion rate, but the opposite opinion also exists. The rate of spontaneous abortions has been analysed retrospectively in a group of SP with and without amniocentesis. The same parameters were also evaluated for MP. The risk of spontaneous abortions following MTAcz is nearly 2.5 times higher in MP (1.7% vs. 3.89%) than in SP, but is still within the range of normally elevated biological risk (4.5%) of this group of subjects.
