Delayed death due to traumatic dissection of the common carotid artery after attempted suicide by hanging

Systematic analysis of nonfatal suicide attempts and further diagnostic of secondary injury in strangulation survivors: A retrospective cross-sectional study

Background and Aims

Data on nonfatal suicide attempts in Germany are sparse. The study aimed to analyze data on nonfatal suicide attempts and consecutive diagnostic steps to identify secondary injuries after strangulation.

Methods

All admissions after nonfatal suicide attempt in a large Bavarian psychiatric hospital between 2014 and 2018 were reviewed and the methods were analyzed.

Results

A total of 2125 verified cases out of 2801 registered cases of nonfatal suicide attempts were included in further analysis. The most common methods were intoxication (n = 1101, 51.8%), cutting (n = 461, 21.7%), and strangulation (n = 183, 8.6%). Among survivors of strangulation with external neck compression (n = 99, 54.1%), no diagnostic steps were performed in 36 (36.4%) patients and insufficient imaging in 13 (20.6%) patients. Carotid artery dissection was detected in two (4.0%) of 50 patients with adequate neuroimaging.

Conclusions

This study provides details on nonfatal suicide attempts in Germany. Slightly more than half of the patients with strangulation underwent adequate diagnostic work-up, with 4.0% being diagnosed with dissection. Further studies with systematic screening for dissection after strangulation in psychiatric hospitals are recommended to reduce possible under-reporting.

Post-obstructive Pulmonary Oedema in Delayed Death by Hanging: A Case Report

Hanging is a common method to attempt suicide, which is highly lethal and results in immediate death. Near-hanging refers to those who survive a hanging injury and are able to reach a hospital. Only a few survive such episodes if they are promptly rescued, but they usually die later, which is called delayed death by hanging. Post-obstructive pulmonary oedema is a fatal complication that occurs after the removal of severe upper respiratory tract obstruction. Post-obstructive pulmonary oedema developing in delayed hanging death is not widely reported in the literature. Herein, we describe a case of post-obstructive pulmonary oedema in a 16-year-old girl with a history of attempted suicide by hanging.

Neck vascular lesions in hanging cases: A literature review

The aim of this review was to investigate the types and rates of vascular lesions occurring in cases of completed hanging and near-hanging, defined in literature. In the literature to date, 6 specific types of vascular injuries have been defined in cases of death as a result of hanging. These are Amussat's sign, Etienne Martin's sign, Dominguez-Paez sign, Friedberg-Lesser sign, Ziemke-Otto's sign, and Lupascu sign. As a result of this study, it was determined that the most defined finding was the Amussat sign, and it was concluded that the other findings were not sufficiently recognized. Likewise, considering that the proportional differences are due to the differences in the rates of autopsy practice and autopsy protocols between countries, it can be suggested that international joint autopsy protocols should be developed at the meetings in which national professional associations participate.
