Can varicose veins be treated with the so-called liquid knife polymer intervention?

Patient.
Varicose veins in lower limbs with itchy skin symptoms
I read in a newspaper that the latest treatment of Shanghai Haisong Hospital, the liquid knife polymer intervention method, can remove varicose veins without surgery, just by injection, and does not leave any after-effects. Is this treatment scientific? Will there be any after-effects if the surgery is performed? Because I trust the military hospital, I would like to ask what treatments are available if I come to Changhai Hospital. Mei Zhijun, Department of Vascular Surgery, Shanghai Changhai Hospital
