Left Subclavian Arterial Coverage and Stroke During Thoracic Aortic Endografting: A Systematic Review

We report a systematic review of 63 studies comprising more than 3,000 patients. We conclude that stroke risk after TEVAR is increased by LSA coverage, and that LSA revascularization reduces stroke risk. LSA revascularization may lower the rate of posterior stroke. TEVAR for aneurysm is associated with increased stroke risk compared to TEVAR for dissection.

Today's open access paper is a review of potential approaches that might be used as a basis for therapies to restore a more youthful level of neurogenesis in the aging mammalian brain. Neurogenesis is the process by which new neurons are created by neural stem cell populations and then integrated into neural networks. In adults, neurogenesis is essential to memory, learning, and the limited degree of regeneration that the brain is capable of enacting. Unfortunately, the supply of new neurons declines with age as the underlying stem cells become ever less active. Beyond making the aging brain more resilient, methods of incr...

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications. To What Degree Does Loss of Skeletal Muscle with Age Contribute to Immunosenescence? https://www.fightaging.org/archives/2019/11/to-what-degree-does-loss-of-skeletal-muscle-with-age-contribute-to-immunosenescence/ Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

Introduction: Stroke is a devastating complication following thoracic endovascular aortic repair (TEVAR). Studies have found conflicting results on stroke risk following TEVAR with concurrent left subclavian artery (LSA) coverage alone (pooled reported rates ranging between 4.7-7.8%) and whether LSA revascularization results in lower stroke rates (pooled reported rates ranging between 4.1-5.8%). Therefore, we compared stroke rate following TEVAR with differing LSA management strategies in the real-world setting of a nationwide clinical registry.

This study assessed outcomes of open and endovascular repair of this disorder.MethodsBetween 1997 and 2016, 152 adult patients presented with KD at Cleveland Clinic (Cleveland, OH), 87 had no intervention, and 65 underwent open repair (n = 55; 19 elephant trunk [ET] procedures [9 with aortic dissection], including 7 frozen ET, and completions with 5 thoracic endovascular aortic repairs, 2 open, and 5 lost to follow-up) or endovascular procedures (n = 10). Non-ET open KD repairs consisted of resection (n = 15), interposition graft (n = 16), patch (n = 4), or aortopexy (n = 1). Maximum KD diamet...

CONCLUSION: Arterial haemodynamic characteristics are affected by LSA branched stent graft configurations, with pressure drops and energy losses likely to be clinically insignificant. The length of the stent graft protrusion into the aortic lumen generated the largest haemodynamic variations in the aortic system. Protrusions up to 5 mm have smaller risk of potential thrombus generation. Conversely, larger protrusions into the aortic lumen showed more disturbed haemodynamics, suggesting a greater risk of potential thrombus formation, which may be clinically important over time.
