Stent thrombosis is a challenging problem following percutaneous coronary intervention that can lead to serious clinical consequences, such as death and acute myocardial infarction. Its pathophysiology is not yet completely known, and there are several causes suggested, such as incomplete stent endothelization, presence of polymers and late incomplete stent apposition. One of the main predictors is the early discontinuation of dual antiplatelet therapy. Stent improvements related to their design, with more friendly metallic platforms, thinner biocompatible or biodegradable polymers, absence of polymers, and even stents manufactured with bioabsorbable materials, could make the percutaneous procedure much safer and effective, allowing its application in increasingly complex anatomic and clinical scenarios, with low thrombosis rates.

Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, and the most common form is coronary artery disease (CAD). Treatment options include coronary artery bypass surgery (CABG) or percutaneous heart intervention (PCI), but both have drawbacks. Bare metal stents (BMS) are commonly used to treat CAD; however, they lead to restenosis.

Background: One of the most serious complications of coronary artery stenting is restenosis and in-stent thrombosis; their prevalence can reach 20-25%. Stent thrombosis can be acute (up to 24 hours), subacute (24 hours to 30 days), late (30 days to 1 year), and very late (> 1 year after previous stenting). In the patients with COVID-19 in intensive care units, the proportion of those with elevated troponin levels reached 25%.

Coronary artery disease remains a significant global health issue and is a leading cause of mortality. Dual antiplatelet therapy, including clopidogrel, is essential for preventing stent thrombosis after coronary artery stenting. This study assessed the comparative efficacy and safety of generic versus brand-name clopidogrel in a large Taiwanese cohort.

Materials And Methods: Patients with iliofemoral obstructive venous disease and treated with venous stents were retrospectively enrolled in a physician-led real-world data collection effort. Results were analyzed by etiologies: post-thrombotic syndrome (PTS), non-thrombotic iliac vein lesion (NIVL), and iliocaval acute deep vein thrombosis (aDVT).
