Clinical Characteristics of Neck Stab Wounds: A Single-Institute Retrospective Study of 89 Patients

Abstract

Background and Objectives Neck stab wounds should be managed properly as they can result in life-threatening complications and death. However, guns are prohibited in South Korea and many previous studies conducted in other countries are thus inapplicable. Also, most of the existing case reports deal mostly with profound neck injury and might lead to misunderstanding regarding the severity of injuries when considering neck stab wounds. This study analyzed the clinical characteristics of neck stab wounds according to the cause of trauma. Subjects and Method A total of 89 patients with neck stab wounds who visited the emergency room between January 2005 and June 2017 were enrolled. Medical records and radiological findings were reviewed retrospectively. The patients were divided into two groups according to the cause of trauma (suicide attempt or assault by another person). A comparative analysis of the two groups was conducted. Results The patients consisted of 41 cases of (46.1%) attempted suicides and 26 cases of (29.2%) psychiatric disorders. Of these, more than half had superficial wounds above the platysma, and multiple anatomical lacerations were found in 40 cases (45%). Psychiatric diagnoses were identified only in the attempted-suicide group (p<0.001), and injuries to the posterior neck triangle were observed only in the assault-by-another-person group (p=0.029). There were 11 cases (12.4%) of profound injury, but there was no significant difference between the two groups. One patient with injury by another person died due to the cutting of the common carotid artery. Conclusion Superficial injuries were more common while profound injuries were relatively uncommon in this study. However, physicians should pay attention to proper evaluation and management comprehensively in cases of neck stab wounds.
