All India Institute of Medical Sciences (AIIMS) successfully completed the first phase of surgery to separate two-year-old twins from Odisha, who are joined at the head which went on for around 20-hours.
Doctors performed venous bypass to separate the veins shared by the babies that return blood to the heart from the brain.
"The surgery began on Monday at around 9 am and went on till 5 am on Tuesday. The children are under observation," a senior doctor at AIIMS said.
According to the doctor, the surgery to separate them will be taken up by October end. The twins — Jagannath and Balram — from Kandhamal district in Odisha, are craniopagus conjoined twins who are joined at the head. This is a very rare
condition.
A team of around 20 specialists from the renowned institute's neurosurgery, neuro-anaesthesia and plastic surgery department besides, a Japanese expert were involved in the procedure.
A series of investigations, including multiple MRIs, CT scans and angiograms, were carried out on the twins to see to what extent the veins in their brains are fused and whether surgery was feasible. The twins were shifted to AIIMS on July 13.
Deepak Gupta, professor of neurosurgery, earlier had said the twins suffer from the condition which afflicts one in 30 lakh children, of which 50 per cent die either at birth or within 24 hours.
Surgery is feasible only on 25 per cent of the survivors while the rest continue to live with the condition. "Also, there is less than a 20 per cent chance of survival among those who undergo this surgery. Such operations are extremely challenging," Gupta had said.
