Femoral artery pseudoaneurysm due to a gunshot injury.
Femoral artery pseudoaneurysms are commonly iatrogenic due to increasing use of the artery for arterial interventions. Other reasons of pseudoaneurysm formation are intravenous drug use and penetrating trauma. Here, we have discussed the management strategy of a femoral artery pseuodoaneursym and the modalities for preventing the misdiagnoses of the pseudoaneurysm in the emergency department. A 50-year-old male patient was referred to our emergency department (ED) with claudication and severe local swelling. Ten days earlier, he had been referred to another ED immediately after a gunshot injury to the left inguinal zone. Duplex ultrasound and CT angiography of the left lower extremity revealed a 4 cm sac of pseudoaneurysm on the distal part of posterofemoral branch of deep femoral artery and a"Dateline" team worked with veteran tower dog Doug Delaney for four months documenting this group of tower climbers as they worked their way through 40 towns and cities in 24 states. During this time there were seven fatalities nationwide, including five deaths in a 12-day period in April.
