Abstract

In recent times we have seen new developments in ultrasound imaging, in particular in vascular imaging, resulting in a different diagnostic approach and in the ability to obtain information that invasive techniques often do not provide. The association of ultrasound and doppler has changed the approach to vascular conditions because it is dependable, non-invasive and it can therefore be repeated. The possibility of combining ultrasound and doppler, and recently colour doppler, results in combined information about appearance and haemodynamics of the region investigated. The vascular pedicles of 20 myocutaneous flaps have been evaluated pre-operatively by colour duplex imaging. In all patients the test was conducted with an ultrasound scanner Logiq 500 (General Electrics) with a 7.5 MHz linear probe and a 3.5 Mhz convex probe. The controllable parameters are: acoustic intensity, gain, lenght impulse, change of the direction of the beam, colour gain, colour sensitivity, following processing. All patients were examined by the same person. The following regions were examined: 10 cases: inferior epigastric artery 6 cases: superior gluteal artery 2 cases: posterior humeral circumflex artery 2 cases: highest thoracic artery. In five cases the study was conducted on 'controls' affected by clinically evident atherosclerosis of the lower limbs, three of which presented diabetic artery disease. The aim of this study is to assess the meaning and dependability of colour duplex imaging and its possible use in clinical practice.
