Medical statistics show that about 90% of women and over 65% of men suffer from varicose veins with varying severity.
The main cause of the disease is the failure of the venous valve, which is responsible for the backflow of blood, because of which it begins to accumulate and turn into deadly clots. Currently, varicose veins are most effectively treated with three methods - surgery, laser therapy and radiofrequency oblation.
A group of scientists from St. Petersburg Polytechnic University and Medical University named after I.I. Pavlova turned to the most advanced method of treatment - theranostic, which simultaneously combines diagnosis and therapy. Within the framework of this joint project, a theranostic device is being developed, with the help of which it will be possible to close the lumen of the veins.
The treatment session is carried out non-invasively, that is, without damaging the skin. An ultrasound module is installed on the leg, which detects the affected valve, after which it begins to process it with a narrowly focused ultrasound beam that cauterizes the vessel walls.
The peculiarity of the Russian device is the ability to obtain a volumetric image of a vein using an ultrasonic sensor.
