Stents play a crucial role in the treatment of various cardiovascular and arterial diseases, including coronary artery disease, peripheral artery disease, renal artery stenosis, and carotid artery disease. They are used to restore blood flow and prevent life-threatening complications in cases of arterial blockage or narrowing. This paper discusses the pathologies that require stent placement, the different types of commercial stents, and the evolving field of stent geometry design. It also explores the potential of biodegradable stents and the need for further research in this area.
The paper highlights the significance of stent selection based on the specific condition and patient's health, emphasizing the use of drug-eluting stents (DES) and bare metal stents (BMS) in clinical practice. It presents clinical trials evaluating the safety and efficacy of different stent types and materials, with a focus on biodegradable stents (BDS). The research suggests that BDS may offer a promising alternative by reducing the risk of long-term complications associated with stent placement.
In addition, the study emphasizes the importance of optimizing stent geometry to strike a balance between flexibility and support while minimizing issues such as foreshortening during expansion. It proposes innovative approaches, such as 3D-printed patient-specific stents and smart stents that monitor plaque accumulation and arterial conditions in real-time.
