“…Optimal stent size and optimal post-dilatation might explain this finding, despite the fact that some stents were only 12 mm in diameter. Migration has been reported previously, probably due to small stent caliber and insufficient post-dilatation (7,9). In two cases, the migrated stents were inserted in the iliac vein using a stent diameter of 10 and 12 mm.…”

“…While fracture rates have been rigorously investigated in arterial diseases, venous stent integrity over time is less well described (6). Few cases of iliac venous stent fracture and stent migration to the heart have been published (7)(8)(9). In addition, there are no long-term follow-up data on whether duplex ultrasound (DUS) scan alone is sufficient to detect potential stent problems such as kinking, straightening, and fracture that may impact long-term patency of stented segments.…”

Background Long-term surveillance data on venous stent integrity is sparse. There is limited knowledge on whether duplex ultrasound (DUS) can detect potential stent deformities such as kinking, straightening, and fracture, which may impact long-term patency of the stented veins. Purpose To assess venous stent integrity after at least five years of follow-up and to establish the efficacy of DUS as surveillance in patients with venous stent. Material and Methods A total of 45 patients with acute iliac-femoral deep vein thrombosis (DVT) treated with catheter directed thrombolysis (CDT) and stenting >5 years before follow-up. Stents were evaluated with 3D volume low dose non-contrast computed tomography (CT) and DUS for kinking, straightening, stent fracture, and patency. Results from CT scans and DUS were compared to assess the overall agreement between the methods. Results Median follow-up was 13.2 years (mean = 11.2 years; range = 5.2–15.8 years). 3D CT reconstructions showed normal stent configuration in 47 stents (89%). All intact stents were identified by DUS. In the remaining six stents, 3D CT reconstructions showed compression, tapering, kinking, and minor fracture. DUS recognized all stent complications except the minor fracture. Overall agreement between CT and DUS was 98% (kappa = 0.90). Two cases of stent occlusion were found. Conclusion The long-term physical resilience of iliac vein stents evaluated with 3D CT in patients treated with CDT for iliofemoral DVT was high. Stent deformities were mostly compression, whereas fracture was rarely seen. DUS seems to be sufficient to evaluate venous stent integrity.

“…Migrating stents have been reported to lead to right atrial perforation and pericardial effusion. [2][3][4] A case report noted dual stents migrating into the right atrium and to the left pulmonary artery. 5 We present an asymptomatic patient with venous stent migration that lead to severe tricuspid regurgitation requiring tricuspid valve replacement.…”

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. Intracardiac stents may require open surgery to prevent life-threatening complications. We present an asymptomatic patient with stent migration that lead to severe tricuspid regurgitation and required tricuspid valve replacement

“…Clinicians have increasingly come to favor stents to restore and maintain venous patency in patients with iliac vein obstruction. 1 However, stent-related complications, including thrombosis within the stent, contralateral iliac vein and veins of the lower extremities, and stent migration into the right ventricle, 2 have been reported. They have several causes.…”

Stents have been widely used to restore the patency of the iliac vein in the treatment of its obstruction. However, various complications related to those stents have been reported. This case report covers a 67-year-old male who was diagnosed with left iliofemoral venous post-thrombotic syndrome with recurrent acute deep venous thrombosis. Thrombosis of the inferior vena cava was induced by pronounced extension of left iliac vein stents. Extending stents in this way covers the outlet of the contralateral common iliac vein and may induce thrombosis in the inferior vena cava.
