Summary: Venous stent thrombosis is associated with anticoagulant treatment in cancer patients with nonthrombotic iliocaval or iliofemoral venous obstruction, and has a lower occurrence rate when compared to patients not receiving anticoagulation. Therapeutic anticoagulation plays a protective role against stent thrombosis in this population.

Summary: Through a retrospective review, it was found that iliac vein stenting could improve arterial-venous reflux if present initially, but its effects on deep venous reflux remained unclear. Further prospective studies are needed to confirm the safety and efficacy of iliac vein stenting for patients with deep venous reflux.

Summary: This study validates a novel device for venoplasty sizing and compliance measurements, which utilizes real-time electrical conductance measurements and pressure measurement. The results demonstrate that the device provides accurate, repeatable, real-time measurements of venous size and compliance, enabling assessment of venous lesions and guiding interventions.

Summary: This study suggests that nonthrombotic IJVS may be a risk factor for CVT, and anticoagulation therapy may be considered for patients with IJVS.

Summary: This study focuses on improving postoperative stent patency rates in PTS patients and identifies prognostic factors affecting patency. It found that stent implantation is an effective therapeutic option for PTS patients with iliofemoral vein occlusion but patent inflow.

Summary: In-stent restenosis (ISR) and stent compression (SC) are common issues after stenting for chronic iliofemoral venous obstruction, with onset within 1 day post-intervention and peaking by 3 months. Reintervention should be considered based on symptom recurrence and impact on quality of life, rather than the percentage of ISR or degree of SC.

Summary: This article provides an overview of in-stent restenosis (ISR) in iliofemoral venous stents, including the pathology, diagnosis, and management considerations. Treatment options for ISR include balloon angioplasty, laser ablation, atherectomy, and Z-stent placement. More research is needed to understand the underlying causes of ISR and to develop preventive measures.

Summary: The presence of thrombophilia does not affect clinical outcomes after deep venous stenting for post-thrombotic syndrome. Using the same anticoagulation protocol, patients with and without thrombophilia had similar stent patency rates and rates of reinterventions to maintain stent patency. Therefore, thrombophilia should not be a factor in determining eligibility for iliofemoral venous stenting.

Summary: This study evaluated the feasibility of using self-expanding venous stents for treating iliofemoral venous obstruction and found that the stents can significantly increase patients' patency rates and improve outcomes, especially for those with acute deep vein thrombosis, nonthrombotic iliac venous lesions, and post-thrombotic syndrome.

Summary: The study compared subtherapeutic and therapeutic anticoagulation regimens following nonthrombotic venous stent placement and found that they produced equivalent outcomes in terms of adverse event rates, reintervention rates, and symptomatic improvement.

Summary: This study evaluated the predictive factors of primary stent patency in three groups of patients with a history of lower limb vein thrombosis: non-thrombotic iliac vein lesion, acute deep vein thrombosis, and post-thrombotic syndrome. The results showed that patients with non-thrombotic iliac vein lesion had significantly better primary stent patency compared to patients with post-thrombotic syndrome and acute deep vein thrombosis.

Summary: This study evaluated the outcomes of using Bard Venovo stent compared to Wallstent-Zenith stent in the treatment of chronic iliofemoral venous obstruction. The results showed comparable clinical outcomes, quality of life improvement, and stent patency between the two stent configurations. However, further study is needed to confirm long-term improvement.

Summary: This study examined the role of short-term anticoagulation on iliac vein stent patency in patients with nonthrombotic iliac vein lesions. The findings suggest that perioperative anticoagulation therapy for prophylaxis of stent thrombosis is unnecessary for patients with nonthrombotic iliac vein lesions.

Summary: This study evaluates the diagnostic performance of post-PCI pressure gradients to detect residual focal lesions and stent underexpansion. The results show that post-PCI FFR gradients can effectively predict IVUS-detected distal and proximal lesions, while Pd/Pa and dPR gradients have poor predictive ability. Gradients within the stent are not useful for detecting stent underexpansion.

Summary: This study includes 1008 patients, and the results show that iliac venous stenting in post-thrombotic syndrome presents durable mid-term patency rates and significant symptomatic improvement. The technical success rate was 96%, with primary and secondary patency rates of 98.2% and 100% at 30 days, 78.1% and 94.5% at 12 months, and 66.3% and 89.4% at 36 months, respectively.
