Fig. 1.Schematic of pseudoaneurysm arising from superficial femoral
artery. Double-headed arrow indicates biphasic flow through neck of
pseudoaneurysm during systole and diastole. Thrombin is injected through
25-gauge needle while flow pattern is monitored with sonographic probe.
Fig. 2A.Pseudoaneurysm (PSA) in 72-year-old woman. Color-flow Doppler
sonography before injection of thrombin shows neck of pseudoaneurysm is 5 mm,
and flow jet is easily seen.
Fig. 2B.Pseudoaneurysm (PSA) in 72-year-old woman. Color-flow Doppler
sonography before injection of thrombin shows neck of pseudoaneurysm is 5 mm,
and flow jet is easily seen.
Fig. 2C.Pseudoaneurysm (PSA) in 72-year-old woman. Color-flow Doppler
sonography after injection shows complete cessation of flow in pseudoaneurysm
occurring immediately after thrombin injection.
