title: Stenting for chronic post-thrombotic vena cava and iliofemoral venous occlusions: mid-term patency and clinical outcome.
abstract: OBJECTIVE
  The aim of this study was to determine the mid-term patency and the clinical outcome after stenting of chronic occluded caval and iliofemoral venous segments.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  During the period 2000 and 2009, 2400 patients with chronic venous insufficiency (CVI) were evaluated, and 34 with chronic venous occlusions after deep venous thrombosis (DVT) were selected for endovascular treatment. The median age was 41 (range 15-63) years, and 19 were female. The following investigations were undertaken: colour duplex ultrasound (CDU), ascending venography (AV), venous occlusion plethysmography (VOP), venous pressure gradient (VPG) and CT venography or trans-femoral/popliteal venography. The major symptoms were venous claudication, oedema, pain and ulcer. All patients were treated by stenting occluded segments. Self-expanding stents were deployed in 22 iliofemoral, nine iliac and one caval-iliac-femoral. Twenty-one procedures required stenting across the inguinal ligament.
  
  
  RESULTS
  Primary recanalisation was accomplished in 32/34 (94%). The median follow-up was 33 months (1-96) with clinical examination, CDU and VOP. Two-year primary patency was 14/21 (67%), primary-assisted patency 16/21(76%), and secondary patency was 19/21 (90%). Venous claudication and oedema resolved in those successfully recanalised. Four of the seven ulcers healed.
  
  
  CONCLUSIONS
  Stenting to treat venous claudication, oedema and recurrent venous ulcer caused by post-thrombotic chronic venous occlusions has positive clinical outcome and good mid-term patency.
