Background: Distal migration is one of the common complications after insertion of a covered metallic stent. Stent repositioning or removal is not always possible in every patient. Therefore, trimming using an argon plasma coagulator (APC) may be a good alternative method to solve this problem.
Methods: Metallic stent trimming by APC was performed in 2 patients with biliary Wallstent migration and in another patient with esophageal Ultraflex stent migration. The power setting was 60-100 watts with an argon flow of 0.8 l/min.
Observations: The procedure was successfully performed and all distal parts of the stents were removed. No significant collateral damage to the nearby mucosa was observed.
Conclusions: In a patient with a distally migrated metallic stent, trimming of the stent is possible by means of an APC. This new method may be applicable to other sites of metallic stent migration.

Background And Aims: Efficacy and safety of EUS-guided placement of lumen-apposing metal stents (LAMS) has been reported yet advantage of using 15-mm LAMS over 10-mm LAMS yet to be explored.
Methods: International, retrospective, case-matched study of patients with intra-abdominal abscess who underwent EUS-guided drainage with 15-mm (case) and 10-mm (control) LAMS between 03/2019 and 09/2022.
Results: 51 patients underwent EUS-guided drainage using LAMS [15-mm 29 (57%), 10-mm 22 (43%)].
Delayed open-heart operation to remove migrated intracardiac inferior vena cava stents in a living donor liver transplantation recipient: a case report.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Endoscopic retrograde cholangiopancreatography is considered the gold standard for treating benign and malignant biliary obstructions. However, its use in complex biliary obstructions is limited. Over the past decades, therapeutic endosonography (EUS) and emerging technologies such as lumen-apposing metal stents have enabled endoscopic treatment of conditions previously requiring non-endoscopic or surgical approaches.

Flow diversion is a transformative approach in neurointerventional surgery for intracranial aneurysms that relies heavily on effective antiplatelet therapy. The ideal approach, including the timing of treatment, the use of dual antiplatelet therapy (DAPT), and the number of flow-diverter devices to use, remains unknown. DAPT, which combines aspirin with a thienopyridine like clopidogrel, prasugrel, or ticagrelor, is the standard regimen, balancing thromboembolic protection and hemorrhagic risk.

Percutaneous Coronary Intervention (PCI) is a treatment method that involves reopening narrowed arteries with a balloon catheter that delivers a cylindrical, mesh-shaped implant device to the site of the stenosis. Currently, by applying a coating to a bare metal stent (BMS) surface to improve biocompatibility, the main risks after PCI, such as restenosis and thrombosis, are reduced while maintaining the basic requirements for the mechanical behavior of the stent itself. In this work, for the first time, the development and optimization process of the spatial structure of the Co-Cr stent (L-605) with a graphene-based coating using cold-wall chemical vapor deposition (CW-CVD) to ensure uniform coverage of the implant was attempted.
