[Diagnosis of femoral pseudoaneurysm using 2-dimensional and Doppler echography].

Femoral artery pseudoaneurysm was found by combined 2D, pulsed and continuous wave Doppler echography in 10 out of 16 patients with hematoma formation following cardiac catheterization. The typical features included an echofree area communicating with the femoral artery through a narrow neck. There was a low velocity systolic flow in the pseudoaneurysm and a high velocity systolic and reverse diastolic flow in the neck.
