The material covers 332 twin pregnancies (including 5 of triplets) of which 208 (62.7%) were premature deliveries and 124 (37.3%) deliveries at term.
Of the twin pregnancies included in the group examined 15.7% developed complications (gestosis and eclampsia, kidney and heart diseases, anemia, hydramnios). Spontaneous deliveries were 66.7%, operative deliveries 33.3%. A high mortality of the second twin (13.1%) is noticeable and it increases to 21.4% when operative procedures are applied to the first twin.
