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.
AbstractAfter acute ischemic stroke (AIS), peripheral monocytes infiltrate into the lesion site within 24 h, peak at 3 to 7 days, and then differentiate into macrophages. Traditionally, monocytes/macrophages (MMs) are thought to play a deleterious role in AIS. Depletion of MMs in the acute phase can alleviate brain injury induced by ischemia. However, several studies have shown that MMs have anti-inf lammatory functions, participate in angiogenesis, phagocytose necrotic neurons, and promote neurovascular repair. Therefore, MMs play dual roles in ischemic stroke, depending mainly upon the MM microenvironment and ...
Conclusion: AF may be related with worse outcomes in patients undergoing MC implantation, including long-term mortality, major bleeding, and rehospitalization. AF should be taken into account when referring a patient for MC treatment.
The location of blunt thoracic aortic injuries (BTAI) frequently results in inadequate proximal seal for thoracic endovascular aortic repair (TEVAR) unless the stent graft is advanced into aortic zone 2, covering the left subclavian artery. Although well described for aneurysm treatment, the risks associated with this coverage are perceived as less important in trauma, with up to 50% reported rates of left subclavian artery coverage (LSAC) during BTAI repair. We aimed to estimate current rates of LSAC during TEVAR for BTAI and assess the complications associated with LSAC.
This study aims to develop a score to predict the risk of in-hospital stroke after TEVAR.
ConclusionThere is a higher 30 ‐day mortality rate during OOH surgery, yet this is affected by large volume centers and this difference diminished following sensitivity analysis. There were no significant differences in major postoperative outcomes. Therefore, operating on such cases should be decided on clinical priority witho ut delay.
ConclusionAcute organ malperfusion caused by the aortic dissection requires accurate and prompt diagnosis to proceed with an appropriate intervention before repairing the central aorta for preventing irreversible organ damage.
Conclusion Various independent risk factors for mortality in elderly MV repair patients could be identified, but overall survival rates were similar to those of the general population. Consequently, our data indicates that repairing the MV in elderly patients represents a suitable and safe surgical approach.

Abstract Stroke is a leading cause of death and disability worldwide. Several mechanisms are involved in the pathogenesis of ischemic stroke (IS). The contributory role of the inflammatory and immunity processes was demonstrated both in vitro and in animal models, and was confirmed in humans. IS evokes an immediate inflammatory response that involves complex cellular and molecular mechanisms. All components of the innate and adaptive immunity systems are involved in several steps of the ischemic cascade. In the early phase, inflammatory and immune mechanisms contribute to the brain tissue damage, whereas, in the l...
ConclusionThe use of a branch first aortic arch replacement technique in ATAAD results in improved outcomes and is an approach applicable to all cardiac surgeons not only the aortic sub specialist.
ConclusionsPostoperative implantation of a permanent RV pacemaker does not alter the long ‐term risks of HF and mortality following mitral valve surgery.
