Percutaneous transluminal angioplasty (PTA) with stenting is widely used in the treatment of vascular disorders, but restenosis remains a significant problem. Drug-eluting stents (DES) have been developed as an attempt to reduce the intimal response leading to restenosis. Drugs used in DES include mainly immunosuppressive and anti-proliferative compounds. Glucocorticoids are also an interesting possibility for those purposes because they have anti-proliferative effects in vascular smooth muscle cells and down-regulate the production of cytokines and growth factors driving inflammation and fibrosis. In this MiniReview, feasibility and safety of drug-eluting metal and biodegradable vascular stents are discussed with special emphasis on dexamethasone-eluting stents.

Surgical treatment experience of seven cases of Berry syndrome.

Beijing Children's Hospital Capital Medical University Beijing, Beijing, China.
Objective: Berry syndrome is a group of rare congenital cardiac malformations including aortopulmonary window (APW), aortic origin of the right pulmonary artery (AORPA), interruption of the aortic arch (IAA), patent ductus arteriosus (PDA) (supplying the descending aorta) and intact ventricular septum. This paper will analyze the clinical data of 7 patients with Berry syndrome who underwent surgical treatment in our institution and discuss the one-stage surgical correction of Berry syndrome in combination with the literature.
Methods: From January 2013 to July 2024, a total of 7 children with Berry syndrome were admitted to the Cardiac Surgery Department of Beijing Children's Hospital.
Plaque heterogeneity influences in-stent restenosis following drug-eluting stent implantation: Insights from patient-specific multiscale modelling.

In-stent restenosis represents a major cause of failure of percutaneous coronary intervention with drug-eluting stent implantation. Computational multiscale models have recently emerged as powerful tools for investigating the mechanobiological mechanisms underlying vascular adaptation processes during in-stent restenosis. However, to date, the interplay between intervention-induced inflammation, drug delivery and drug retention has been under-investigated.

Objective: Popliteal artery injury is a rare but serious complication of arthroscopic knee surgery. The absence of comprehensive data and standardized guidelines underscores the urgent need for further investigation. This study examines the incidence, risk factors, management strategies, and long-term outcomes of popliteal artery injury in the context of arthroscopic knee procedures.

Background: Abdominal aortic aneurysm (AAA) is a localized bulge of the abdominal aorta, which mainly manifests as a pulsatile mass in the abdomen. Once an abdominal aortic aneurysm ruptures, the patient's life is seriously endangered. Surgery is the preferred treatment for abdominal aortic aneurysm.

Both veins experienced significant compression - OLCIV proximally and ILCIV medially - due to the overlying right common iliac artery (RCIA) and lumbar spine. The patient presented with bilateral spider veins, lower extremity swelling, pelvic discomfort, and bilateral leg cramping.
