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.
