title: Surgical management of iliofemoral vein thrombosis during pregnancy and the puerperium.
abstract: The risk of deep venous thrombosis is elevated during pregnancy and the puerperium. Therapy is usually limited to conservative measures as invasive thrombus removal is feared because of possible complications. However, leg- or life-threatening situations require fast thrombus removal, and the long-term rate of post-thrombotic syndrome (PTS) may be reduced by venous recanalization. Our center's experience may give support to surgical venous thrombectomy (VT).
  
  
  
  Between 1996 and 2016, all women who received VT for pregnancy-related deep venous thrombosis in our department were included. Retrospective data were combined with a current follow-up.
  
  
  
  The study included 82 women with a mean age of 29 years (17-38 years). An additional arteriovenous fistula was performed in 79 and planned simultaneous cesarean section in 13 patients. Neither pulmonary emboli nor fetal complications occurred during surgery, and perioperative and postoperative mortality was 0%. Operative revision was required in 38% mainly for rethrombosis (24%) and bleeding (12%). One fetus died 2 months after VT of unrelated causes. After a mean of 83 months, complete venous recanalization was seen in 88%, venous valve sufficiency in 90%, and PTS in 31% without any ulcers. At 10 years, PTS incidence rose to reach 50% with limited statistical significance because of the number of patients reaching long-term follow-up.
  
  
  
  Iliofemoral venous recanalization during pregnancy can be performed safely in a specialized center, with lower PTS rates than in historical controls.
