A 69-year-old man fell in a park and sustained a neck injury from a tree branch and then attempted to self-suture the wound at home without anesthesia using a household needle and thread. A 3-cm-deep wound exposing the internal jugular vein was found, and computed tomography revealed extensive emphysema from the neck to the mediastinum caused by incomplete wound closure. Although self-suturing is often associated with psychiatric disorders, no such disorder was identified in this case, and the behavior was considered related to idiosyncratic personality traits.
Ishizuka et al. (Wed,) studied this question.
