The distal veins are removed following the complete ablation of the proximal vein. This treatment is most commonly used for varicose veins off of the great saphenous vein, small saphenous vein, and pudendal veins. [60] Follow-up treatment to smaller branch varicose veins is often needed in the weeks or months after the initial procedure.
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Oftentimes, though, collateral veins are used instead, which is where other veins can take the blood as an alternate pathway so it doesn’t stagnate in the varicose vein, and these tend to actually be the deep veins in the legs. Other than the legs, in men it can also occur in the scrotum (usually on the left side) where it is called a varicocele.
CHIVA method is a type of surgery used to treat varicose veins that occur as a result of long term venous insufficiency. [1] The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency).
For example, the superficial venous system (SVS) can be very well examined using a high-frequency probe of 12 MHz. For patients who have thick adipose tissue, a probe of 7.5 MHz will be required. Deep veins require probes of around 6 MHz, while the abdominal vessels are better studied with probes of between 4 and 6 MHz. [9]
Sclerotherapy can also be performed using microfoam sclerosants under ultrasound guidance to treat larger varicose veins, including the great and small saphenous veins. [20] After a map of the patient's varicose veins is created using ultrasound, these veins are injected whilst real-time monitoring of the injections is undertaken, also using ...
