In addition, under the direction of a physician with experience in ultrasound imaging, each repair site was assessed dynamically to determine the relative thickness of the repair site, as compared to the adjacent tendon, and was also compared to the contralateral limb. Dynamic measurements were utilized to determine if the tendon was able to glide freely, or if it dragged the adjacent tissues with it. Peritendinous and intratendinous edema was also noted when observed.

Doppler ultrasound is the initial modality of choice to differentiate venous malformations from other vascular abnormalities. Ultrasound is performed with a high-frequency linear array transducer (5-12 MHz). On grey-scale images, venous malformations appear as compressible hypoechoic or heterogeneous lesions [15,16] (Fig. 2.2a-c). Calcifications (demonstrated in less than 20% of cases), are quite specific of venous malformation anechoic channels can be seen. Doppler examination displays a monophasic low-velocity flow (Fig. 2.3). In 20% of venous malformations, no flow can be demonstrated. Dynamic manoeuvres such as Valsalva or manual compression are sometimes necessary to induce a visible Doppler flow.
