The surgery, considered a safe procedure, involved transferring unwanted fat from the patient’s belly to his penis.
This marks the first known death from penis enlargement surgery, the journal reports.
Surgeons first performed a penile elongation on the man, incising the base of his penis to loosen a ligament. They then began the enlargement process by injecting two fluid ounces of fat cells into the patient’s penis.
But some of the fat intended to increase his member’s girth loosened during surgery, travelling through the punctured veins to his lungs, where they ruptured blood vessels, the study concluded.
The patient went into cardiac arrest and was given CPR, but it was unsuccessful. He died hours later.
