The distinction between femoral artery pseudoaneurysms and other causes of groin masses: value of duplex Doppler sonography

Pseudoaneurysm of the Uterine Artery After an Uncomplicated Spontaneous Vaginal Delivery

“…16 In general, pseudoaneurysms have a characteristic sonographic appearance consisting of a pulsating anechoic or hypoechoic structure connected to a parent artery by a small neck, with swirling blood flow on color Doppler images. 17 Spectral Doppler waveforms of the neck show turbulent arterial blood flow with a to-and-fro pattern of antegrade systolic flow and pandiastolic flow reversal as a result of the aforementioned pressure gradient. 12 However, sonographic demonstration of the neck in a uterine artery pseudoaneurysm may be difficult because of the small size of the parent artery, 18 as may have been the case with our patient.…”

Color flow-guided repair of axillary artery pseudoaneurysm

“…Pulsed Doppler revealed a high flow jet at the neck of the pseudoaneurysm, and the typical, turbulent flow sig· nals within the pseudoaneurysm itself. 2 Communication between the pseudoaneurysm and the axillary artery was identified using color flow Doppler (Fig. 1 8).…”

Avoidable morbidity in a patient with pseudoaneurysm of the uterine artery after cesarean section

“…Pseudoaneurysm should be considered in any complex cystic lesion found in the wall or parauterine region, and appropriate Doppler examination should be performed, which is 95% sensitive and specific for a pseudoaneurysm. 6 Upon detecting bidirectional ''to and fro'' flow, a diagnosis of pseudoaneurysm can be reliably established. 7 Contrast-enhanced CT (angiographic phase) can be used as an adjuvant to diagnosis as well as for interventional planning.…”
