When Nancy Andrews, of Commack, N.Y., became pregnant after an in vitro fertilization procedure at a New York fertility clinic, she and her husband expected a beautiful new addition to their family. What they did not expect was a child whose skin was significantly darker than that of either parent. Subsequent DNA tests suggested that doctors at New York Medical Services for Reproductive Medicine accidentally used another man's sperm to inseminate Nancy Andrews' eggs. The couple has since raised Baby Jessica, who was born Oct. 19, 2004, as their own, according to wire reports. But the couple still filed a malpractice suit against the owner of the clinic, as well as the embryologist who allegedly mixed up the samples.
In yet another case of a wrongful operation, surgeons mistakenly removed the healthy right testicle of 47-year-old Air Force veteran Benjamin Houghton. The patient had been complaining of pain and shrinkage of his left testicle so doctors decided to schedule surgery to remove it due to cancer fears. However, the veteran's medical records suggest a series of missteps -- from an error on the consent form to a failure on the part of medical personnel to mark the proper surgical site before the procedure. The error, which took place at the West Los Angeles VA Medical Center, spurred a $200,000 lawsuit from Houghton and his wife. 

For the third time on the same year, doctors at Rhode Island Hospital have operated on the wrong side of a patient's head.. The most recent incident occurred Nov. 23 2007. An 82-year-old woman required an operation to stop bleeding between her brain and her skull. A neurosurgeon at the hospital began a surgery by drilling the right side of the patient's head, even though a CT scan showed bleeding on the left side, according to local reports. The resident reportedly caught his mistake early, after which he closed the initial hole and proceeded on the left side of the patient's head. The patient was listed in fair condition on Sunday. The case echoes of a similar mistake last February, in which a different doctor operated on the wrong side of a patient's head. And last August, an 86-year-old man died three weeks after a surgeon at Rhode Island Hospital accidentally operated on the wrong side of his head.
7.The Surgeon who removed the wrong leg

In what was, perhaps, the most publicized case of a surgical mistake in its time, a Tampa (Florida) surgeon mistakenly removed the wrong leg of his patient, 52-year-old Willie King, during an amputation procedure in February 1995. It was later revealed that a chain of errors before the surgery culminated in the wrong leg being prepped for the procedure. While the surgeon's team realized in the middle of the procedure that they were operating on the wrong leg, it was already too late, and the leg was removed. As a result of the error, the surgeon's medical license was suspended for six months and he was fined $10,000. University Community Hospital in Tampa, the medical center where the surgery took place, paid $900,000 to King and the surgeon involved in the case paid an additional $250,000 to King.
8.The healthy kidney removed by mistake

In St. Louis Park, Minnesota, a patient was submitted at Park Nicollet Methodist Hospital to have one of his kidneys removed because it had a tumor believed to be cancerous. Instead, doctors removed the healthy one. "The discovery that this was the wrong kidney was made the next day when the pathologist examined the material and found no evidence of any malignancy," said Samuel Carlson, M.D. and Park Nicollet Chief Medical Officer. The potentially cancerous kidney remained intact and functioning. For privacy and family's request, no details about the patient were released.
9.Wide-Awake Surgery led to his suicide


Two months after a double bypass heart operation that was supposed to save his life, comedian and former Saturday Night Live cast member Dana Carvey got some disheartening news: the cardiac surgeon had bypassed the wrong artery. It took another emergency operation to clear the blockage that was threatening to kill the 45-year-old funnyman and father of two young kids. Responding to a $7.5 million lawsuit Carvey brought against him, the surgeon said he'd made an honest mistake because Carvey's artery was unusually situated in his heart. But Carvey didn't see it that way: "It's like removing the wrong kidney. It's that big a mistake," the entertainer told People magazine.
