A seventh conjoined twin was delivered in late January 1971; inclusion of this case as well as the deliveries in January 1971 would lead to an incidence of 1 in 57 975 deliveries and 1 in 546 twin deliveries. Four of the twins were thoracopagus, one craniopagus, one dicephalus tripus tetrabrachius and one syncephalus. One of the thoracopagus twins occurred in a triplet pregnancy. All except two were delivered alive; four died within a few hours to a few days. One thoracopagus survived till 3 months of age; surgical separation was then attempted resulting on one survival who has developed normally and is now 7 years old. Antenatal diagnosis is necessary if the survival rate is to be improved.<\/jats:p>","DOI":"10.3109\/00016347109157342","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T18:12:06Z","timestamp":1260295926000},"page":"373-380","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Cnjoined Twins"],"prefix":"10.1111","volume":"50","author":[{"given":"K.
