Résumé :

Venous thromboembolism is associated with significant morbidity and mortality if left untreated. Anticoagulation is the cornerstone of treatment. Venous stents are a relatively newer entity that are increasingly being used to treat venous stenosis/occlusion. It is a safe procedure, but complications include vein rupture, arterial puncture, retroperitoneal bleeding, and in-stent thrombosis. Stent migration is a rare but potentially fatal complication. We present a case of venous stent embolization to the heart that presented as a non-ST segment elevation myocardial infarction.

Purpose: To report the use of directional atherectomy to treat venous in-stent restenosis (ISR) and subsequent histopathological analysis of retrieved intrastent tissue. Case Report: A 55-year-old man presented with recurrent symptoms of venous congestion following iliofemoral stenting. The stents were found to be occluded on imaging. Directional atherectomy was used to recanalize the iliofemoral venous stents, which provided significant symptom relief. Tissue retrieved from within the stent demonstrated patterns of cellular components similar to arterial ISR. At 6-month follow-up, the stents

Résumé :

<strong>Background</strong>: Venoplasty and venous stenting are commonly used to treat chronically thrombosed veins. However, venous angioplasty alone is often insufficient due to low intravascular pressure in the venous system, necessitating the use of metal stents for long-term patency. Venous outflow obstruction can lead to chronic venous insufficiency, pain, and mobility impairment, requiring precise medical intervention. The Self-Expanding Venous Stent System is an endovascular device designed to maintain vessel patency by providing structural support. It consists of a hybrid closed-cell

Résumé :

Abstract Background Endovenous stenting is a method to overcome venous outflow obstruction in the treatment of patients with acute iliofemoral deep vein thrombosis (DVT) or in those with symptomatic post-thrombotic syndrome (PTS). These treatments allow maximal luminal expansion of the caval and/or iliac venous segment leading to a reduction in venous hypertension. While there is growing enthusiasm for their use, particularly as conventional treatments usually with anticoagulation are not always effective there is however little clinical data regarding efficacy in improving clinical outcome.

Résumé :

Long-term central venous catheters can be associated with central venous stenosis in up to 50% of cases. Central venous stenosis can be managed with central venous stenting which was demonstrated to restore patency and improve suboptimal results after percutaneous transluminal angioplasty. Dislodgment of venous stents into the right side of the heart or the pulmonary artery during stent deployment is one of the most feared complications of this procedure. Percutaneous removal of these migrated stents is the preferred alternative for the more invasive operative intervention, which may be very h

Venous stent migration to the cardiopulmonary system is a rare but serious complication. Cardiopulmonary involvement has various presentations such as valvulopathy, acute heart failure, arrhythmias, endocarditis, and tamponade. The presenting symptoms depend on the eventual location of the stent in the heart or lungs, size of the stent, and valve involvement. Extracardiac dislodgement can be managed by catheter-directed extraction or proper deployment within the containing vessel or surgical extraction.

Background Iliofemoral vein stenosis or occlusion is a common cause of severe chronic venous insufficiency.

Chronic venous obstructions have been treated by means of bypass surgery, until, in recent decades, it was surpassed by endovascular treatment options. Although techniques may differ, some issues should be universal. It is recommended that patients are treated under general anaesthesia. Secondly, obstructive lesions should be fully stented. Finally, self-expandable stents should mainly be used. Recanalization and stenting proved safe and efficient with excellent mid- and long-term patency rates. However, failures due to re-occlusion do occur and are basically related to imperfect stent design

Résumé :

Objectives: The incidence and prevalence of iatrogenic vascular trauma in the United States is staggering. This has led to the advent and implementation of more efficient and effective vascular repair methods. Although open surgical repair may still be considered gold standard, new endovascular solutions have emerged as other viable options. When using an endovascular approach, proper stent sizing is vital to a successful repair. Methods: We present a case of a traumatic injury and pseudoaneurysm formation at the confluence of the right internal jugular and right subclavian veins during a cent

Summary: Background: Physical attributes of conventional 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. Patients and methods: 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. At 3-month follow-up, patency rates were obtained from

Central venous stenosis occurs as a complication of central venous catheterization and significantly complicates delivery of dialysis through arteriovenous grafts in the ipsilateral upper limb. This report includes two separate studies. Functioning expanded polytetrafluorethylene grafts have been prospectively evaluated using duplex scanning and angiography performed in all patients with stenoses >50%. From this, it has been prospectively established that the incidence of unsuspected central venous stenoses in patients with functioning grafts is 29%. In the second part of the report, the au

Abstract Introduction Chronic deep venous insufficiency (CVI) is a common disorder of the venous valves which can cause many debilitating symptoms including edema, pain, and skin changes. CVI may result from a primary non-thrombotic cause, such as May-Thurner syndrome (MTS) or extrinsic compression from a pelvic mass, or as the sequelae of an acute deep vein thrombosis (DVT). Endovascular interventions, including percutaneous transluminal angioplasty and venous stent placement, have been increasingly utilized as a minimally-invasive treatment option for CVI.

Résumé :

The most important vein segment to thrombolyse after deep venous thrombosis (DVT) is the outflow tract meaning the iliofemoral vein. Iliofemoral DVT is defined as DVT in the iliac vein and the common femoral vein. Spontaneous recanalization is less than 50%, particularly on the left side. The compression from adjacent structures, predominantly on the left side is known as the iliac vein compression syndrome. Therefore, it is essential that supplementary endovenous procedures have to be performed in case of persistent obstructive lesions following catheter-directed thrombolysis. Insertion of a

The successful obliteration of torcular dural arteriovenous fistula (DAVF) with a diffuse shunt in the affected sinus may require complex treatment strategies. Therapeutic goals include the preservation of normal venous drainage and complete obliteration of shunt flow. The authors report the case of a torcular DAVF. The treatment of this type of AVF may require a combined approach with transarterial and transvenous embolization, open surgery, or radiosurgery and is associated with many problems.
