A bizarre case of fatal main renal artery partial laceration without primary kidney injury due to a single stab wound in the chest

Reno-vascular injuries are a rare type of renal injury, and their second most frequent cause is penetrating wounds. The majority of the reports and of the studies are present in the urological and radiological literature and they focus on the clinical approach to such injuries. In the case here presented, an 18-year-old male died after being stabbed in the left hemithorax. During body examination, thoracic organs were found to be unremarkable (except for a small peripheral laceration of the left lung), but the diaphragm was transfixed and the upper wall of the left main renal artery was lacerated. The adjacent renal vein, the kidney, the aorta, the vena cava and the surrounding internal structures were not damaged (except for a small laceration of the pancreatic tail). A massive haemothorax and a large retroperitoneal haematoma in the left kidney area were observed. The cause of death was attributed to haemorrhagic shock following a partial laceration of the left main renal artery due to the stab wound to the chest. No other cases of similar fatal renovascular injuries due to stab wounds have been published in the current forensic literature.
