The most significant challenge facing magnesium alloy stents is their ability to withstand complex deformation during their application. To gain a deeper understanding of the impact of stent deformation on the protective capabilities of the coating, this paper presents an amplified stent deformation model. The models were coated with either a low elongation material-Poly(D, L-lactide) (PDLLA) or a high elongation material-Poly(butylene adipate-co-terephthalate) (PBAT), followed by the application of a rapamycin-loaded PLGA as drug-eluting layer.

Endoscopic ultrasonography-guided biliary drainage has been reported as an alternative technique when transpapillary endoscopic biliary drainage fails. This case study describes a case of pseudoaneurysm, one of the complications unique to endoscopic ultrasonography-guided biliary drainage. An 87-year-old woman who underwent endoscopic ultrasonography-guided hepaticojejunostomy with a partially covered metallic stent developed hematochezia.

A 74-year-old man who had received Bacillus Calmette-Guérin therapy for bladder cancer developed vasovagal syncope. Contrast-enhanced computed tomography showed multiple pseudoaneurysms in the left internal carotid artery, aorta, and right common femoral artery, which were considered to be infected aneurysms. Parent artery occlusion was planned for the left internal carotid artery, but the balloon occlusion test was not possible because of the patient's restlessness; therefore, the patient was treated with a Viabahn stent graft.

Vascular access dysfunction remains a significant challenge in hemodialysis patients, primarily caused by stenosis and occlusion in arteriovenous fistulas and grafts. Recent advancements in percutaneous transluminal angioplasty have introduced innovative tools such as drug-coated balloons and stent grafts. Drug-coated balloons enhance patency by reducing neointimal hyperplasia through localized drug delivery, with superior outcomes demonstrated in randomized controlled trials.

A 75-year-old man with a history of open surgical repair for a thoracoabdominal aortic aneurysm presented with an aortic pseudoaneurysm at the anastomosis and a celiac artery aneurysm. During endovascular treatment, multiple celiac artery branches were embolized, and an aortic stent graft was placed to cover the aortic anastomosis and celiac artery origin. Four days post-treatment, a computed tomography scan revealed poor enhancement and fluid collection in the pancreatic body and tail, indicating acute ischemic pancreatitis with pancreatic necrosis.
