[Successful separation in 1974 of craniopagus twins united at the vertex. Indications, technics, follow-up after 14 years].

On July 22, 1974, 55 days after delivery, the separation of female craniopagus twins united at the vertex was performed. This case was very similar to the case published by Voris in 1957 after separation in 1955. Surgery was decided because the neurological examination was normal in both twins, because there was no body malformation, because the angiogram as well as isotopic scintigraphy showed two normal brains, two superior sagittal sinuses and two torcular areas with a short venous union in the middle of the bone defect.
