A Canadian man was taken to the St. Paul's Hospital in Vancouver for an emergency procedure called fasciotomy to save his limbs. The operation was a success but what the doctors found along the way reminded them of old Star Trek episodes.

The patient actually had blood with a dark-greenish shade similar to the character Mr. Spock in the famed TV series. Upon further investigation, the doctors found out what was causing the change in color.

As it turned out, the patient was taking medication for his migraine and was popping in 200 milligrams of a drug called sumatriptan into his system every day. Doing so resulted in a very rare condition called sulfhaemoglobinaemia, which happens when components of the drug mix with the color-causing hemoglobin in red blood cells.

The doctors, led by Dr. Alana Flexman, ordered the patient to stop taking the drug immediately. After five weeks of observation, the man's blood was back to normal and the legs that were operated on had almost fully recovered.
