Fatal craniofacial circular-saw-related injury: a rare case of accidental death.

Fatal injuries caused by circular saws are rare and mainly self-inflicted. To the best of our knowledge this is the first recorded case of accidental death of a woman caused by an injury to the head region inflicted by a saw blade. The autopsy showed a 35 cm long wound, stretching from the right half of the jaw along the right side of the face and the right temporal region up to the parietal region. The cut went through the right hemisphere of the brain in the temporal and parietal lobe regions, damaging the sagittal sinus. Air embolism was considered to be the cause of death. Fatalities involving power tools, such as a circular saw, warrant a high degree of suspicion of criminal activity and require a comprehensive medicolegal investigation. Placing guards over the blade and around the driving system, i.e. the motor, belt, arbor, is of great importance for the prevention of potentially fatal injuries.

Forensic Implications of Sternal Bone Marrow Biopsy Fatalities: Autopsy Case Report.

Iatrogenic penetrating injuries of the thoracic aorta are rare. When surgical treatment is delayed or unavailable, they are associated with high mortality. Herein we present a case of a 36-year-old woman who had a sternal marrow biopsy performed due to laboratory-confirmed pancytopenia. Autopsy revealed 4 needle punctures extending through the full thickness of the upper right quarter of the sternum. Mediastinal soft tissue and the upper part of the pericardium were diffusely effused with blood. On the aortic arch, between the innominate artery and the left common carotid artery, we found a linear penetrating injury (2 mm in length). Autopsy revealed bilateral hemothoraces, the right hemothorax being generally larger than the left (2000 mL vs 50 mL of blood). In the presented case, the cause of death is considered to be exsanguination due to iatrogenic injury of the aorta during sternal bone marrow aspiration. Death occurring during or after medical procedures requires extremely careful postmortem evaluation.

Iatrogenic tracheoarterial fistula: Case report and literature review.

Tracheo-innominate fistula is a rare but recognised life-threatening complication most commonly associated with prolonged endotracheal intubation. We report the case of a 16-year-old boy who developed a tracheo-innominate fistula secondary to the prolonged intubation after a pool accident. After 16 days of hospitalisation, the patient died as a consequence of a massive haemorrhage into the tracheobronchial tree and asphyxia. This is a rare complication, and to our knowledge, no case of tracheo-innominate fistula or any other case series concerning this rare complication has been reported in Serbia recently. This case report addresses the epidemiology of a trachea-innominate fistulisation as a complication of prolonged tracheal intubation, with a special overview of its forensic importance as an iatrogenic injury.
