We retrospectively investigated the usability of arterial access ports (AAPs), which are blind-ending short prosthetic grafts anastomosed to the brachial artery (BA) and implanted subcutaneously, via which cannulation and blood-drawing from the BA was performed. Nineteen AAPs in 16 patients were evaluated. The AAP cumulative functional usage rate tended to drop within a year after its implantation because of infection and inappropriate positioning; however, its usability was extended for a maximum of 97 months after re-implantation. The operative modification of minimal superficial repositioning of the BA anastomosed with the graft significantly improved its usage rate by easing the cannulation via the graft and eliminated usage withdrawal caused by infection and dislocation. Occlusion, thrombus, and ligation of the BA never occurred even after surgical repairs for infectious AAP. The use of an AAP as a shunt-less vascular access could be an alternative to BA superficialization with avoidance of direct BA puncture.

Background: Extracorporeal membrane oxygenation (ECMO) is a critical treatment for severe cardiopulmonary failure. However, traditional ECMO decannulation methods, such as manual compression and surgical repair, are associated with significant complications. This study evaluates suture-mediated closure devices, specifically Perclose ProGlide, as a potentially favorable decannulation strategy.

Mediastinal lymphangiomas are rare benign tumors arising from lymphatic system malformations, most commonly seen in pediatric populations. In adults, they are exceedingly rare and present diagnostic challenges due to nonspecific symptoms and imaging overlap with other mediastinal masses. Diagnosis is typically based on imaging, including CT and MRI, with histopathology confirming the diagnosis.

Background Carotid artery stenting is a well-established alternative treatment to carotid endarterectomy for carotid artery stenosis for preventing stroke. This study assessed the procedural and clinical outcomes in patients undergoing carotid artery stenting in a tertiary care center in India. Methods A total of 39 patients underwent carotid artery stenting from January 2022 to December 2023, with different embolic protection devices and carotid stents.

Importance: To decrease associated infectious and thrombotic morbidity, it is important to understand the indications and risks of peripherally inserted central catheters (PICCs) and other vascular access means in pregnancy.
Objectives: The objectives are 3-fold: (1) discuss indications and contraindications, approach to placement, and associated complications for PICC lines, arterial catheters, centrally inserted central catheters, and peripheral intravenous catheters; (2) review available data regarding complications associated with these catheters in pregnancy; and (3) propose an evidence-based approach to clinical decision making regarding vascular access in 2 clinical scenarios among pregnant patients.
Evidence Acquisition: A literature review identified relevant research, review articles, textbook chapters, databases, and societal guidelines, with a focus on obstetrical anesthesia and obstetric literature.

As novel, anti-amyloid therapies have become more widely available, access to timely and accurate diagnosis has become integral to ensuring optimal treatment of patients with early-stage Alzheimer's disease (AD). Plasma biomarkers are a promising tool for identifying AD pathology; however, several technical and clinical factors need to be considered prior to their implementation in routine clinical use. Given the rapid pace of advancements in the field and the wide array of available biomarkers and tests, this review aims to summarize these considerations, evaluate available platforms, and discuss the steps needed to bring plasma biomarker testing to the clinic.
