METHOD OF ONE-STAGE TREATMENT OF SURFACE THROMBOPHLEBITIS IN RECURRENT VARICOSE VEIN BY MEANS OF ENDOVASAL LASER OBLITERATION (VERSIONS) Russian patent published in 2020 - IPC A61B17/00 A61B18/20 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely cardiovascular surgery. Endovasal laser obliteration is performed under ultrasonic control using an ultrasonic device with a linear sensor. Thrombotic masses are localized both in transverse and longitudinal scanning. That is followed by loc puncture with an introducer of a target vein under ultrasonic control at an upper border of the thrombus. A J-guide is inserted, an angiographic catheter is inserted to guide the laser obliteration light guide, wherein the light guide is carried over the entire length of the recurrent vein and is localized 1-2 cm from falling into deep veins. It is followed by hydropreparation with the help of a cooled physical solution or 0.25 % novocaine in an amount of not more than 500 ml along the entire recurrent vein under ultrasonic control. Thereafter, laser power of 10 W is fed into the light guide and traction is performed in manual or automatic mode at rate of 1 mm per second. That is followed by closing the puncture point with an aseptic sticker and applying compression jersey to the surgical site. In another version, endovasal laser obliteration is performed under ultrasonic control using an ultrasonic device with a linear sensor. Thrombotic masses are localized both in transverse and longitudinal scanning. Local anesthesia is followed by puncture with an introducer of a target vein under ultrasonic control in an inguinal fold. Then J-conductor is introduced either directly into sapheno-femoral fistula, or directly into proximal segment of vein. An angiographic catheter is inserted to insert a light guide for laser obliteration to an upper thrombone boundary. That is followed by hydropreparation with the help of a cooled physical solution or 0.25 % novocaine in an amount of not more than 500 ml along the entire recurrent vein under ultrasonic control. Then, laser power of 10 W is supplied to the light guide and traction is performed in manual or automatic mode at rate of 1 mm per second. That is followed by closing the puncture site with an aseptic sticker and applying compression jersey to the surgical site.

EFFECT: group of inventions enables preventing recurrence of disease, performing one-stage treatment with achieving a high therapeutic effect.
