Inferior and Superior Vena Cava Reconstruction.

Obstructions of the superior and inferior vena cava are prevalent etiologies of deep venous obstruction, presenting a spectrum of clinical manifestations ranging from life-threatening conditions to asymptomatic states. The etiological diversity inherent to these central venous obstructions necessitates a subtle approach to their diagnosis and management. This discrepancy in clinical presentations emphasizes the importance of a differentiated diagnostic and therapeutic strategy, tailored to the specific form of vena cava obstruction encountered.

The TOPOS study.

: We aimed to study the long-term safety and efficacy of oblique venous stents for post-thrombotic syndrome (PTS) with iliac vein compression. : In the multinational, prospective, single-arm TOPOS study, PTS patients scheduled for endovascular therapy with the sinus-Obliquus stent and optional distal extension with the sinus-Venous or sinus-XL Flex stent were enrolled at eight European vascular centres between October 2016 and December 2020. The primary outcome was primary stent patency at 24 months, and secondary outcomes included the clinical course of PTS (Villalta score, revised Venous Clinical Severity Score [rVCSS], Visual Analog Scale [VAS] of pain), quality of life changes (Chronic Venous Insufficiency Quality of Life Questionnaire, CIVIQ-20), and device-related complications.

The toolbox of acute DVT intervention.

Although the thrombectomy system is very important, there are many other devices and supportive tools that build the foundation for a successful interventional procedure. We suggest a toolbox of acute DVT intervention to aid in all likely strategies to effectively remove thrombus from the deep venous vasculature.

Braided nitinol stent for chronic iliofemoral venous disease - the real-world BLUEFLOW registry.

In patients with iliofemoral chronic venous disease (CVD) secondary to post-thrombotic or non-thrombotic obstruction, venous outflow obstruction after adequate anticoagulation alone is still frequent and post-thrombotic syndrome is a common complication. Thus, we aimed to evaluate mid-term effectiveness and safety of a novel braided venous stent for venous outflow obstruction treatment. Consecutive patients who underwent venous recanalization with a new braided, closed cell, venous stent for non- or post-thrombotic CVD were eligible for inclusion in our retrospective, observational study.

Outcome of stenting in central venous obstruction of benign etiology.

: The aim of this study is to evaluate long term outcome in patients treated for benign superior vena cava (SVC) syndrome by endovascular techniques. : Between 2015 and 2018, 62 patients suffering from central venous obstruction of benign etiology underwent balloon angioplasty with stent placement for venous obstruction in our department. Patency was assessed clinically, using duplex ultrasound in all patients or with CT-phlebography in selected cases.

Early clinical outcomes for treatment of post-thrombotic syndrome and common iliac vein compression with a hybrid Oblique self-expanding nitinol stent - the TOPOS study.

: Physical attributes of onventional stents used in the ilio-caval territory are often unfavorable in the presence of external compression close to the bifurcation. A hybrid oblique stent was developed for the treatment of common iliac vein compression without compromising the contralateral iliac vein inflow. : The ongoing international monitored TOPOS study enrolled 60 patients with post-thrombotic syndrome (PTS) treated with the sinus-Obliquus stent (optimed) and provisional distal stent extension.

Safety, procedural success and outcome of the AspirexS endovascular thrombectomy system in the treatment of iliofemoral deep vein thrombosis - data from the Arnsberg Aspirex registry.

Percutaneous mechanical thrombectomy (PMT) represents a treatment option in addition to conventional therapy for patients with iliofemoral deep vein thrombosis (DVT). We sought to determine the safety, patency and short-term outcome of the AspirexS catheter as a rotational mechanical thrombectomy device in the endovascular treatment of iliofemoral DVT. 56 patients (66 % female, median age 51 years) undergoing mechanical thrombectomy with the AspirexS catheter for endovascular treatment of iliofemoral DVT were included in the analysis.

Patency rates, safety and clinical results of the sinus-Obliquus venous stent in the treatment of chronic ilio-femoral venous outflow obstruction - data from the Arnsberg venous registry.

We sought to determine the patency and clinical symptom relief following the usage of the sinus-Obliquus venous stent in the endovascular treatment of venous obstruction of the ilio-femoral track in short-term. 48 patients (62 % female, mean age 57 years) with chronic unilateral post-thrombotic obstruction (PTO) and non-thrombotic iliac vein obstructive lesions (NIVL) without involvement of inferior vena cava receiving a sinus-Obliquus venous stent was included in the analysis. Clinical improvement determined by the revised venous clinical severity score (rVCSS) as well as the clinical, etiologic, anatomic and pathophysiologic score (CEAP), safety, and stent patency rates were determined at baseline and at 1, 6 and 12 months after stent placement.
