[A post-thrombotic pelvic congestion syndrome].

INTRODUCTION: Pelvic congestion syndrome is a chronic pelvic pain syndrome related to pelvic varices developed in the setting of primary venous insufficiency or secondary to venous obstruction.

OBSERVATION: We report the case of a 35-year-old patient undergoing anticoagulant therapy for an extensive unprovoked left iliac vein thrombosis, who developed a disabling pelvic congestion syndrome secondary to chronic obstruction of the left iliac vein. Recanalization with stenting of the left iliac vein, combined with antithrombotic treatment with antiplatelet therapy (aspirin 100mg) and anticoagulation (rivaroxaban 20mg) for three months, followed by antiplatelet therapy alone, led to a complete and lasting regression of symptoms.

DISCUSSION: Management of pelvic congestion syndrome secondary to post-thrombotic lesions must take into account its pathophysiology. It involves iliac venous angioplasty with stent placement in combination with antithrombotic therapy, which modalities remain to be specified in long-term follow-up.
