  • Title: Delayed presentation of popliteal artery pseudoaneurysm following blunt trauma.
    Author: Atta HM, Tagoe A, Walker ML.
    Journal: Am Surg; 1997 Jun; 63(6):496-9. PubMed ID: 9168760.
    Abstract:
    Popliteal artery pseudoaneurysms are not uncommon. They may result from penetrating or blunt trauma, arterial reconstructive surgery, invasive diagnostic or surgical orthopedic procedures, and perigenicular neoplasia. We report two patients with popliteal artery pseudoaneurysm diagnosed 3 months and 3 weeks, respectively, after blunt trauma. These two patients as well as many patients reported in the literature had palpable distal pulses and no obvious clinical signs of arterial injury following various forms of trauma. Arteriography in these circumstances is usually abandoned because of the low yield and the possible risk of complications. However, as we illustrate in this report, noninvasive diagnostic modalities such as duplex ultrasound and magnetic resonance arteriography are both safe and accurate for early detection of popliteal artery pseudoaneurysm. Once diagnosed, standard vascular reconstruction should be performed to prevent potential complications.
