Ruptured femoral artery pseudoaneurysm in drug abuser mimicking homicidal inguinal stab wound.
A 47-year-old woman with a long-term history of intravenous heroin use was found dead lying on the couch in a pool of blood with the wound in her right groin, 15 × 4 mm in diameter. The autopsy revealed the thickened superficial right femoral artery wall and the tract communication between the artery lumen and the skin surface, with pseudoaneurysm formation, confirmed by microscopic examination. Toxicological findings were negative for heroin and its metabolites. The cause of death was fatal blood loss from ruptured chronic femoral pseudoaneurysm. Persons with a long-term history of intravenous drug use experience injection-related problems: prominent vein scarring, lumps, and swelling. The risk of injecting the groin is substantially greater than in typical areas such as the cubital fossa. The proximity of the femoral vein to the femoral artery and nerve poses the risk of accidental trauma to these sites. Accidental groin arterial injections can cause a tear in the arterial wall, on which a pseudoaneurysm can develop. A false or pseudoaneurysm is a breach in the vascular wall leading to an extravascular hematoma that freely communicates with the intravascular space. In the presented case, the autopsy findings pointed out that the fatal blood loss from femoral pseudoaneurysm rupture occurred probably after trivial trauma (shortly after sexual intercourse) or even spontaneously, and not immediately or shortly after arterial drug injection.

Exsanguination from ruptured femoral artery pseudoaneurysm - A fatal complication of groin heroin injection.
Intravenous drug users (IDUs) eventually encounter a common problem- a need to turn to a new vessel to inject drugs. Whether it is because no other spot is available due to scarring or convenience, the groin is the preferred spot for some. Chronic puncture of femoral vessels can lead to a rare but significant complication- femoral artery pseudoaneurysm (FAP). Its fatal consequence- rupture and bleeding is well recognized, but the forensic literature on this subject is limited. We present eight cases of exsanguination due to the ruptured FAP in IDUs who share most or all the following characteristics: long-term heroin use and/or pronounced drug use stigmata, chronic groin injection-related lesions, absence of significant precipitating pseudoaneurysm trauma, and no or minimal concentrations of heroin metabolites in blood. The FAP presentation varied greatly, from palpable fist-sized mass or slight elevation under the skin defect to infundibular arterio-cutaneous fistula that ruptured through the skin induration. In some, surrounding skin or soft tissue showed signs of inflammation but without suppuration. The most prominent FAP characteristic was smooth-surface cavitation on cross-sections. We performed microscopic evaluation in two cases and verified disruption of the artery wall (i.e., pseudoaneurysm) with elements of acute and chronic inflammation and fibrosis; foci of fibrinoid necrosis were noticed on the arterial wall. All subjects were pale, with faint hypostasis and organ anemia, consistent with reported massive hemorrhage. Because such sudden, unwitnessed, and suspicious deaths may raise the question of injury infliction, proper autopsy evaluation is crucial, for which we propose guidelines.

On-Scene Rescue Breathing Resulting in Gastric Perforation and Massive Pneumoperitoneum.
Rescue breathing performed too vigorously or by untrained individuals may cause gastric distension and perforation. A 26-year-old woman is presented who developed acute abdominal pain and distension after receiving rescue breathing following a heroin overdose. Massive pneumoperitoneum was seen on chest x-ray, and on subsequent laparotomy, a 4cm laceration was found in the lesser curvature of the stomach. Review of the literature suggests that the lesser curvature is particularly susceptible to perforation following over-distension. Emergency personnel should be aware of this rare, but serious, complication. Expansion of community and first responder naloxone use in the proper clinical setting may further diminish utilization of rescue breathing. Butterfield M , Peredy T .
