Pregnancy outcomes in 16 women with previous catheter-directed thrombolysis and stenting for acute left iliofemoral deep vein thrombosis

Abstract

Background Whether iliac vein stents affect pregnancy or whether they will be affected by pregnancy was rarely reported in the literature. The aim of this study was to report our experience of pregnancy in women who received thrombolysis and stenting for a previous deep vein thrombosis (DVT). Methods 16 patients with previous stenting for treatment of acute left iliofemoral DVT who had subsequent pregnancies were identified. Patient demographic information and outcomes were recorded. Duplex scanning and venography were performed as scheduled to evaluate the patency of stents in perinatal period and at 12 months after delivery. Results None of the patients had a hemorrhagic complication and recurrent venous thromboembolism during their pregnancies and postpartum. No stent compression/occlusion and structural damage occurrence in all patients during follow-up. Conclusion Pregnancy managed with prophylactic dalteparin resulted in no re-thrombotic events or structural damage to the iliac stents and did not appear to negatively affect pregnancy outcomes.
