How to Perfuse: Concepts of Cerebral Protection during Arch Replacement

Arch surgery remains undoubtedly among the most technically and strategically challenging endeavors in cardiovascular surgery. Surgical interventions of thoracic aneurysms involving the aortic arch require complete circulatory arrest in deep hypothermia (DHCA) or elaborate cerebral perfusion strategies with varying degrees of hypothermia to achieve satisfactory protection of the brain from isch...

How I Treat How I use fibrinogen replacement therapy in acquired bleeding

Fibrinogen is a critical protein for clot formation, providingamatrix and mesh network essential for clot strength. Maintaining fibrinogen levels is an important therapeutic target in bleeding patients, particularly in perioperative settings. Early studies demonstrated that fibrinogen repletion corrected clot strength, based on viscoelastic blood testing using thromboelastography/thromboelastom...
