Acute iliofemoral deep venous thrombosis due to giant ovarian tumor: report of a hybrid treatment.

Ovarian tumors rarely cause acute iliofemoral thrombosis due to direct compression. This case represents an example of successful therapy using an interdisciplinary approach. A 37-year-old woman was admitted with a painful swelling of the left lower limb. Computed tomography revealed a giant abdominal mass originating from the left ovary producing a thrombotic occlusion of the left iliofemoral veins. Surgical treatment consisted of complete tumor removal, adnexectomy and appendectomy. During the same operation, transfemoral thrombectomy and stent implantation in the iliac vein were performed, followed by creation of an arteriovenous fistula in the left groin. Hystologic examination revealed a well-differentiated mucinous ovarian adenocarcinoma. The patient recovered well and is tumor-free 6 months after surgery. The deep venous system is still patent at follow-up. In this case, minimal surgical trauma and complete tumor as well as thrombus removal succeeded through a positive complementary interdisciplinary approach.
