According to the backinfo I got, this young guy got his throat slashed by a kite twine.
In the video, he is shown getting the throat surgically sutured. Despite the apparent severity of the injury, neither the jugular veins nor the trachea were severed. As such, he was able to breathe and the blood supply to his brain was not impacted.
Unfortunately, there is a cut in the video, so it jumps from him having a slash in the throat, to having it fully sutured. Apparently, he remained conscious and in good spirit throughout the stitching.
Props to Best Gore member @african-angel for the video:
