  • Title: One-Year Results of Iliocaval Stenting.
    Author: Tosenovsky P.
    Journal: Ann Vasc Surg; 2019 Aug; 59():208-216. PubMed ID: 30826434.
    Abstract:
    BACKGROUND: The aim of the study was to assess results of interventions for iliocaval obstruction or compression in patient with acute and chronic venous disease. METHODS: Patients with chronic venous insufficiency (CVI) C3-C6 (Clinical, Etiology, Anatomy, Pathology - classification of venous insufficiency) and acute deep venous thrombosis were assessed by ultrasound scan, computed tomography, venography, and/or intravascular ultrasound, and if an obstruction in their iliocaval or iliofemoral segments were confirmed, they underwent venoplasty and stenting. Acute deep venous thrombosis cases were treated with pharmacomechanical and/or catheter-directed thrombolysis and residual obstruction was then stented. RESULTS: One hundred eighteen consecutive limbs were treated between October 2011 and December 2017. Thirty-two limbs had an active ulcer (27%), 27 limbs had healed ulcer or advanced skin changes (23%), 39 limbs had swelling with or without other symptoms of CVI (33%), 15 limbs had acute symptomatic deep venous thrombosis (13%), and the residual 5 iliac vein cases were causing pelvic congestion syndrome (4%). Patency rates of the stents in acute cases were 84.6%, 76.9%, 76.9%, and in chronic cases (combined thrombotic and nonthrombotic) 93.1%, 91%, and 89.9% in 3, 6, and 12 months, respectively. A relief of symptoms was achieved in 81.5 % of limbs at some stage during the first 12 months (most of them within the first 3 months), although at the end of this period only 59.3% remained free of symptoms. There was no limb loss and no mortality within 30 days from the intervention. CONCLUSIONS: Iliocaval and iliofemoral venoplasty and stenting in both acute and chronic obstruction cases can be performed safely with good patency rates and reasonable improvement of symptoms of CVI.
