Fatal. This is 5 in the most horrible that happens when your type.

However, it seems that some mistakes can not be avoided in some surgical operations.
Reporting from Listverse, in 2011, 29 incidents of error occurred in operation.
Things that happen like doctors perform the wrong treatment procedure, the doctor forgot the surgical equipment in the patient's body, as well as perform surgery on the wrong patient.

1. A 17-year-old child has the wrong liver and lung during the transplant
   In 2003, 17-year-old Jesica Santillan suffered the worst ever.
   Santillan underwent surgery on February 7, 2003. But doctors use organs from donors with the wrong blood type.
   Donors have blood type A while Santillan has blood type O.
2. An 83-year-old woman undergoing heart surgery for respiratory infections
   Rita du Plessis, and she was admitted to the Kimberley Mediclinic hospital in Johannesburg, South Africa due to a respiratory tract infection.
   The cardiac surgeon mixed up the patient's name and instead took du Plessis for heart surgery, even his family was told after the surgery was done.
3. A woman loses breasts because of a cancer she has never suffered
   In April 2015, 49-year-old Eduvigis Rodriguez underwent an operation to deal with aggressive cancer in his left breast.
   Sick breasts were taken and the medical officer realized his mistake after the surgery that Rodriguez did not have cancer.
   The alleged complaints are caused by sclerosis adenosis, an extra benign tissue growth in the breast.
4. Patients experience brain surgery is not right
   By 2018, Kenyatta National Hospital in Kenya will perform the patient's brain surgery.
   Patients who require surgery have blood clots in their brain and others have only swollen heads placed in the same ward.
   The surgeon pushed the patient with a swollen head into the operating room and they realized the error after two hours and then dissected the patient's head.
5. The patient loses a healthy kidney during an operation that he does not need
   An unnamed patient at St. Hospital Vincent in Worcester, Massachusetts, was left with a kidney after doctors thought he was the one who needed kidney surgery.
   The actual patient, whose CT scan showed a tumor in his kidney, was supposed to undergo surgery to remove it.
