Study of delayed deaths in hanging: Unravelling post-obstructive pulmonary oedema as the primary cause of death

Suicide by hanging is a significant public health concern globally, with delayed deaths presenting unique challenges in understanding the underlying pathophysiology.In this observational study, cases of suicidal hanging resulting in delayed death were isolated, and comprehensive analyses were performed. Data collection included detailed histories of the suicidal attempts, circumstances surrounding the events, medical treatment records, and thorough autopsy examinations, including histopathological analyses. : This study aims to investigate cases of delayed death by hanging and analyse the associated pathophysiological mechanisms.Three cases of delayed death by hanging were identified and analysed in this study. Each case involved individuals who initially survived the suicidal attempts and received medical treatment. Despite efforts, all three individuals succumbed to their injuries after a period of time. Autopsy findings revealed characteristic signs of hanging, along with evidence of post-obstructive pulmonary edema as the cause of death in each case. This study highlights the occurrence of delayed deaths following suicidal hanging and underscores the importance of understanding the pathophysiological mechanisms involved. The identification of post-obstructive pulmonary edema as a significant contributor to mortality in these cases emphasizes the need for timely and effective medical interventions to mitigate adverse outcomes in individuals who survive hanging attempts.
