AI Article Synopsis
Article Abstract
Background: The goal of chest compressions during neonatal resuscitation is to increase cerebral and coronary blood flow leading to the return of spontaneous circulation (ROSC). During chest compressions, bilateral femoral occlusion may increase afterload and promote carotid and coronary flow, an effect similar to epinephrine. Our objectives were to determine the impact of bilateral femoral occlusion during chest compressions on the incidence and timing of ROSC and hemodynamics.
Methodology: In this randomized study, 19 term fetal lambs in cardiac arrest were resuscitated based on the Neonatal Resuscitation Program guidelines and randomized into two groups: femoral occlusion or controls. Bilateral femoral arteries were occluded by applying pressure using two fingers during chest compressions.
Results: Seventy percent (7/10) of the lambs in the femoral occlusion group achieved ROSC in 5 ± 2 min and three lambs (30%) did not receive epinephrine. ROSC was achieved in 44% (4/9) of the controls in 13 ± 6 min and all lambs received epinephrine. The femoral occlusion group had higher diastolic blood pressures, carotid and coronary blood flow.
Conclusion: Femoral occlusion resulted in faster and higher incidence of ROSC, most likely due to attaining increased diastolic pressures, coronary and carotid flow. This is a low-tech intervention that can be easily adapted in resource limited settings, with the potential to improve survival and neurodevelopmental outcomes.

High-Output Mechanical Circulatory Support in Left Main Interventions: The Magenta Elevate High-Risk PCI First-in-Human Study.
JACC Cardiovasc Interv

Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA. Electronic address:
Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.
Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.
Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.
Cyanoacrylate Glue Ablation for Symptomatic Reflux in a Duplicated Femoral Vein: A Case Report.

The literature on minimally invasive techniques specifically targeting reflux in symptomatic femoral vein duplication (FVD) is limited. We present a rare case of symptomatic reflux in FVD, successfully treated with cyanoacrylate glue ablation under ultrasonographic guidance. Our findings suggest that the unique anatomy of FVD can be effectively addressed through percutaneous endovenous glue ablation, providing a technically safe and feasible alternative without open surgery.

Case Presentation: An 89-year-old male who had been holding dabigatran in the setting of transcarotid artery revascularization presented to the emergency department with sudden onset leg pain and weakness. Computed tomography angiography revealed acute aortic occlusion and thrombosis of the bilateral common iliac arteries. He underwent aortoiliac and femoral embolectomies and stenting of the bilateral common iliac arteries and returned to his baseline functional status.

Background: Bypass graft surgery is a key surgical intervention for ischemic heart disease (coronary bypass graft surgery) and critical limb ischemia (peripheral bypass graft surgery). Graft occlusion remains a significant clinical problem for both types. Further research into the pathobiological mechanisms of graft occlusion are needed in order to design targeted therapeutic strategies.

In hemodialysis-related portal-systemic encephalopathy (HRPSE), transient negative pressure in the inferior vena cava (IVC) during dialysis increases the blood flow through a portal-systemic shunt, leading to encephalopathy. We report the case of a 74-year-old man with a gastrorenal shunt who developed HRPSE for the first time following venous occlusion due to thrombosis around a right femoral tunneled-cuffed hemodialysis catheter. Before the thrombosis dissolved, ammonia levels increased after dialysis.
