REVIEW
James Taylor, Caitlin W Hicks, Jennifer A Heller
OBJECTIVE: Pregnancy has significant effects on the lower extremity venous system. Increasing venous pressure and blood volume, in combination with reduced flow rates within the deep veins, predisposes pregnant women to both primary and secondary chronic venous insufficiency (CVI). This review article highlights the specific physiologic and hemodynamic changes that occur during pregnancy and examines the nonpharmacologic, pharmacologic, and invasive interventions that are appropriate for both prophylaxis and treatment of CVI and venous thromboembolism (VTE)...

OBJECTIVE: Chronic venous insufficiency (CVI) affects 25 million adults in the United States. Little emphasis has been placed on inflammatory changes associated with CVI. We hypothesize that in patients with early to mid-stage benign varicose vein disease, differences in circulating inflammatory mediators will be manifested in blood draining the involved area vs circulating blood in control subjects. METHODS: Patients undergoing either endovenous ablation or sclerotherapy for Clinical, Etiology, Anatomy, and Pathophysiology clinical class 3 to 5 disease underwent phlebotomy from regional veins at the time of the procedure...

Iliac vein stenting has become more frequent with improved diagnostic capabilities of intra-vascular ultrasound (IVUS) for recognizing May-Thurner syndrome, chronic venous insufficiency (CVI) and thrombus. In this manuscript, we discuss the reasons for initial stenting, with long-term outcomes and some of the associated pitfalls. The best techniques for re-intervention when iliac stents become occluded will also be discussed.
