Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations. In ultrasound-guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can
Shown in this picture are varicose veins that would be targeted with ultrasound-guided sclerotherapy. Vascular Surgery. Ultrasound is essential to the procedures of ultrasound-guided sclerotherapy and endovenous laser treatment for the non-surgical treatment of varicose veins. [17] Ultrasound-guided sclerotherapy techniques are also used to ...
These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [31] [32] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [1] [33] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.
Most image-guided surgical procedures are minimally invasive. A field of medicine that pioneered and specializes in minimally invasive image-guided surgery is interventional radiology. A hand-held surgical probe is an essential component of any image-guided surgery system as it provides the surgeon with a map of the designated area. [8]
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
CLaCS (Cryo-Laser and Cryo-Sclerotherapy) is a treatment for leg vein lesions by combining transdermal laser effect and injection sclerotherapy, all under skin cooling (Cryo - cold air blown onto the skin at -20C). [1] [2] [3] The laser causes a selective photothermolysis damaging the vein wall. The vein's lumen gets smaller.
This allows for the detection of a pneumothorax with the absence of normal ‘lung-sliding’ and ‘comet-tail’ artifact (seen on the ultrasound screen). Compared with supine chest radiography , with CT or clinical course as the gold standard, bedside sonography has superior sensitivity (49–99% versus 27–75%), similar specificity (95 ...
Real-time 3D ultrasound allows muscles, nerves and vessels to be clearly identified while a needle or catheter is advanced under the skin. This type of ultrasound is capable of imaging the needle regardless of the plane of the image, which is a substantial improvement over 2D ultrasound.
