Management of Patients when Superficial Venous Disease Arises from Pelvic Escape Points

Management of Extra-Pelvic Varicose Veins of Pelvic Origin in Female Patients

Extra-pelvic varicose veins (VVs), originating from incompetent pelvic veins, present a significant clinical challenge, due to their complex anatomy, etiology, and symptomatology. This review aims at providing a comprehensive overview of the diagnostic and therapeutic strategies for these cases and emphasizes the importance of a tailored, evidence-based approach to the effective management of these varicosities, particularly regarding the interplay between the pelvic and extra-pelvic venous systems. Diagnostic workup should be multifaceted, incorporating patient-reported symptoms, physical examinations, and duplex ultrasound imaging. Specific diagnostic assessments include evaluation of the pelvic escape points and the transvaginal and transabdominal ultrasonography, to analyze venous hemodynamics and identify anatomical abnormalities in the pelvic floor and pelvis. In patients presenting with additional pelvic venous insufficiency (PVI)-related pelvic symptoms, advanced diagnostic techniques, such as cross-sectional imaging, venography, and intravascular ultrasound can be valuable to confirm and establish the appropriate treatment strategy. Since most patients with extra-pelvic VVs of pelvic origin do not report pelvic symptoms, minimally invasive procedures, using the "bottom-up" approach, such as ultrasound-guided foam sclerotherapy of the pelvic escape points and extra-pelvic VVs, or surgical ligation and miniphlebectomy for these incompetent veins, are usually sufficient. There are several advantages of these local procedures: they are simple, radiation exposure and injection contrast agents are avoided, they are convenient for the patient since they are performed on an outpatient basis, and they can be easily repeated, if required. When the "bottom-up" treatment fails and the extra-pelvic VVs recur quickly or the patient develops pelvic symptoms, management of the pelvic veins including embolization of the ovarian veins or stenting of the iliac veins should be considered. Careful patient selection is essential to avoid overtreatment and achieve optimal clinical outcomes.

The role of iliac vein stent placement in pelvic venous disorder management

Pelvic venous disease (PeVD) has historically been challenging to diagnose and treat. This paper describes a comprehensive approach to the diagnosis of PeVD and reviews the role of iliac vein stent placement in treatment. Patient selection is vital for non-thrombotic iliac vein lesions (NIVLs) as only a small subset of patients with an NIVL will benefit from stent placement. There is limited, inconclusive data on optimal treatment for patients with both primary ovarian vein reflux and an NIVL. Patients with chronic post-thrombotic outflow obstruction typically have a more favorable risk/benefit ratio for intervention but require anticoagulation and close follow-up due to poorer long-term stent patency. Intravascular ultrasound is a useful tool for identifying obstructive lesions, sizing stents, and planning landing zones. More research is needed to characterize underlying pathophysiology, validate thresholds for intervention, develop reliable methods for outcomes assessment, and determine treatment response. Until this data is produced, an individualized treatment approach is warranted.

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.
