Management Strategies for Chronically Occluded Iliofemoral Veins

This review explores chronic iliofemoral venous obstruction (CIVO), which adversely impacts quality of life and causes significant morbidity through its symptoms of chronic pain, leg swelling, and venous ulceration. The review aims to outline the latest innovations in the diagnosis and treatment of CIVO, with an emphasis on minimally invasive techniques, particularly endovascular intervention like stenting.

Advancements in both diagnostics and treatment of CIVO have drastically altered the landscape of its management. The use of intravascular ultrasound (IVUS) is improving the accuracy of diagnosing venous stenosis as compared to traditional venography by creating high-resolution images in real time that can appropriately estimate the degree of obstruction. In addition, the implementation of venous-specific stents and their associated technological advancements has led to improved post procedural patency and long-term outcomes with improvement in patient symptoms and overall quality of life. However, despite these advancements, challenges remain regarding the optimization of stent design and technology to balance flexibility with adequate resistance to compression.

There has been a paradigm shift in the management of CIVO to minimally invasive techniques, with the emergence of endovascular venous stenting as the favored intervention for those patients who have failed conservative measures. These therapies offer long-term durability and patency in those with CIVO and even those with post-thrombotic syndrome or May-Thurner Syndrome. Ongoing developments in stent technology and hybrid approaches combining surgical and endovascular intervention are expected to continue to enhance future patient outcomes in those with CIVO.
