[Shotgun injury of head and neck: case report].

A 48-year-old male was hit by a shotgun blast from behind while he was hunting. He was only 7 meters away when one of his colleagues pulled the trigger accidentally. About 180 lead pellets penetrated his head and neck. When he was brought to our hospital, he was alert and complained of occipital and nape pain, but had no apparent neurological deficits. We administered 200 mg of dimercaprol immediately and removed 77 pellets by midline suboccipital incision on the next day. Afterwords, we performed four minor operations using a fluoroscope, and removed another 70 pellets by day 29. In addition, we administered a 100 mg x 3 dose of dimercaprol every other week. He was discharged 41 days after the accident without any acute signs of lead poisoning. Though serum lead level did not rise to critical level, EDTA was continued after his discharge to prevent delayed lead poisoning from the retained pellets. Since we seldom encounter this type of patient in Japan, delayed lead poisoning by shotgun injury was discussed with reference to the literature.
