In rare cases where deep vein thrombosis is present, not all varicose veins should be treated, including sclerotherapy. Additionally, if there is an underlying issue with the great saphenous vein, recurrence is frequent, and symptom improvement may be limited, in which case surgery is recommended. However, for asymptomatic spider veins, Dr. Francis Jeon at Evita Clinic personally examines and assesses patients through visual inspection and palpation, often determining that an ultrasound is unnecessary.
