What is the longest time anyone has ever been in a coma?

Desperately in need help.. Sister in coma and stuck abroad. help?

• Me and my family are in desperate need of financial help at the moment. My sister Jamie has been traveling for the past 4 months , visiting Australia, Thailand and so on. Last week on the 2nd of the month , we received a phone call from her friend who she is with that she had been involved in an road accident. We have now found out that she is in a coma and because of her situation/condition and location at present , she has to be transferred to the UK where a specialist in head injuries is , and so she can receive the medical help she needs, otherwise she will basically die the doctors have said. Unfortunately the medical bills are a separate issue , luckily we have private health care back at home , unfortunately she does not have any where she is and they are doing nothing in to help. We have also found out that the bills to get her to the uk are ridiculous due to the medical care she has to receive on board the plane.. we have so far raised nearly 7 thousand pounds , and we are trying everything to get another 8 thousand pounds. If anybody can help , i would ofcorse pay you back once this mess is over with and in time.. but at the moment we are desperate and time is not on our side.. If anyone has a idea or what to do please help.. Matthew
