Download scientific diagram | image of ultrasound doppler tracings from the common femoral artery. note the arterial catheter for drug infusion and or arterial blood pressure measurements. Femoral artery and the deep femoral artery are present alongside the femoral vein, showing a shape reminiscent of mickey mouse’s face on a transverse scan (fig. 3b). the common femoral artery, the bifurcated superficial femoral artery and deep femoral artery are seen in a fallen y configuration in a longitudinal scan (fig. 2). from.
A final hurdle relates to the image acquisition technique for obtaining arterial doppler tracings. the approach for obtaining doppler images during cpr has not been standardized. we chose to image the femoral artery because we found less doppler artifact compared with the carotid artery. A standard duplex ultrasound system with high resolution b mode imaging, pulsed doppler spectral waveform analysis, and color flow doppler imaging is adequate for scanning lower extremity arteries. a variety of transducers are often needed for a complete lower extremity arterial duplex examination. low frequency (2 or 3 mhz) transducers are. One notable exception is the presence of superficial femoral artery disease, where, in the absence of aortoiliac disease, there is a low resistance waveform and low pulsatility index in the common femoral artery resulting in a false positive study suggesting aortoiliac disease . The femoral artery runs down the front and medial side of the thigh with the first 4 cm of the vessel enclosed within the femoral sheath together with the femoral vein. lateral but outside the sheath is the femoral nerve. the femoral artery within the femoral triangle (~3 4 cm distal to the inguinal ligament) gives off the profunda femoris.

Fig. 7 duplex doppler images. a, normal common femoral artery and vein. b, with slight compression by ultrasound transducer, femoral vein is almost completely collapsed but artery is unchanged. c, femoral vein filled with echogenic thrombus (arrows) is noncompressible. Doppler imaging with more than 20 years of experience in clinical ultrasound (n¼1). doppler images were obtained using pulsed wave doppler. the transducer was placed over the common femoral artery during cpr to identify the optimal location for pulsatile wave flow. recordings of the arterial doppler signal were obtained during cpr, during.
