Symptomatic recurrent varicose veins due to primary avalvular varicose anomalies (PAVA): A previously unreported cause of recurrence

Pelvic Venous Disorders (PeVD)

Pelvic venous disorders (PeVDs) have replaced the concept of pelvic congestion syndrome encompassing venous origin chronic pelvic pain (VO-CPP) in women. The evaluation of women with VO-CPP includes the assessment for other causes of pelvic pain as well as imaging evaluation for pelvic varicosities measuring greater than 5 mm diameter, ovarian vein diameter, and flow direction, as well as iliac vein diameter and signs of compression. Proper identification of these patients can lead to high degrees of success eliminating chronic pelvic pain following ovarian vein embolization and/or iliac vein stenting. Strong encouragement is provided to use the symptoms, varices, pathophysiology classification for these patients and upcoming research studies on the specific symptoms of patients with VO-CPP will help elucidate patient selection for intervention. Additional future randomized controlled trials are also upcoming to evaluate for outcomes of ovarian vein embolization and iliac vein.

Current Best Practice in the Management of Varicose Veins

This article outlines the current best practice in the management of varicose veins. “Varicose veins” traditionally means bulging veins, usually seen on the legs, when standing. It is now a general term used to describe these bulging veins, and also underlying incompetent veins that reflux and cause the surface varicose veins. Importantly, “varicose veins” is often used for superficial venous reflux even in the absence of visible bulging veins. These can be simply called “hidden varicose veins”. Varicose veins usually deteriorate, progressing to discomfort, swollen ankles, skin damage, leg ulcers, superficial venous thrombosis and venous bleeds. Patients with varicose veins and symptoms or signs have a significant advantage in having treatment over conservative treatment with compression stockings or venotropic drugs. Small varicose veins or telangiectasia without symptoms or signs can be treated for cosmetic reasons. However, most have underlying venous reflux from saphenous, perforator or local “feeding veins” and so investigation with venous duplex should be mandatory before treatment. Best practice for investigating leg varicose veins is venous duplex ultrasound in the erect position, performed by a specialist trained in ultrasonography optimally not the doctor who performs the treatment. Pelvic vein reflux is best investigated with transvaginal duplex ultrasound (TVS), performed using the Holdstock-Harrison protocol. In men or women unable to have TVS, venography or cross-sectional imaging is needed. Best practice for treating truncal vein incompetence is endovenous thermal ablation. Increasing evidence suggests that significant incompetent perforating veins should be found and treated by thermal ablation using the transluminal occlusion of perforator (TRLOP) approach, and that incompetent pelvic veins refluxing into symptomatic varicose veins in the genital region or leg should be treated by coil embolisation. Bulging varicosities should be treated by phlebectomy at the time of truncal vein ablation. Monitoring and reporting outcomes is essential for doctors and patients; hence, participation in a venous registry should probably be mandatory.
