Color ultrasound is a common examination method in vascular surgery, which is fast, accurate, non-invasive and low-cost, and is a technique that should be mastered by all vascular surgeons. However, due to different specialties, limited practice opportunities and expensive ultrasound instruments, very few vascular surgeons have mastered color ultrasound technology at present. Color ultrasound is of great value not only in the diagnosis of vascular diseases, but also in the review of vascular diseases, evaluation of efficacy and treatment such as puncture under ultrasound localization. Patients are examined by the same supervising physician before and after treatment, so that the supervising physician can have a visual understanding of the changes in the patient’s condition and can individualize the treatment for different patients with different outcomes. Also preoperative ultrasound localization by the lead vein surgeon is a routine procedure for varicose vein treatment in developed countries to avoid missing lesions. Traffic vein and small saphenous vein lesions are often not obvious in appearance and must be detected by ultrasound, but the ultrasound reports of most hospitals in China lack the description of these two examinations. Therefore, they are prone to postoperative recurrence. During my work in Shandong Provincial Hospital of Traditional Chinese Medicine, I have spent 1 year to learn vascular ultrasound technology professionally and accumulated thousands of cases of ultrasound diagnosis of vascular diseases, and I have deep research on ultrasound diagnosis of vascular lesions. Meanwhile, all minimally invasive varicose vein surgeries performed by me use intraoperative ultrasound positioning to ensure the quality of surgery to the greatest extent.
