13 Of The World’s Craziest Surgeries Ever Performed On Humankind

4. TWO hearts in ONE body.

No, these are not some cheesy song lyrics. In 2011, Tyson Smith from San Diego actually got a heart transplant while the other heart stayed in his body as well. He now has two hearts beating in his chest and they’re sharing the workload.

Due to the fact that the doctors weren’t sure whether his body would accept a new heart, they simply left the weak one in his chest and added the new one to support it. With the ‘piggyback’ transplant, Mr. Smith can now expect to live approximately ten more years.

5. Womb transplant.

In 2014, the first healthy womb transplant-baby was born in Sweden. The mother had undergone a womb transplant the year before as she had been born without uterus. This successful surgery will spark the hopes of many childless couples as approximately one in 7,000 women are born without a womb or lose their uterus to cancer.

The lead surgeon Professor Mats Brannstrom claims that their success was “based on more than 10 years of intensive animal research and surgical training by our team and opens up the possibility of treating many young females worldwide that suffer from uterine infertility.” However, there are still doubts about this procedure since the medication used to prevent the womb from being rejected by the body can be damaging when taken long-term.

6. Grafting a girl’s hand to her foot.

On her way to school, 9-year-old Ming Liu got hit by a tractor and lost her hand. You might ask yourself why the doctors did not simply reattach the hand to where it actually belonged.

In fact, the arm was so severely damaged that it needed to heal before they could reattach the hand. In the meantime the surgeons had to surgically join the the girl’s hand and foot so that the hand could be kept alive.
