Prevention of perioperative ischemic stroke after non-cardiac and non-neurosurgical operations in the light of the Scientific Statement and Guidelines for the Secondary Prevention of Ischemic Stroke and Transient Ischemic Attack AHA/ASA 2021. Part 2: Perioperative antithrombotic therapy, diagnosis, treatment

One of the possible measures that can enhance the quality of medical care, reduce the number of adverse outcomes, and also achieve target values for the use of reperfusion methods of treatment for acute ischemic stroke is to improve the system of care for patients with in-hospital ischemic stroke. One type of in-hospital stroke is perioperative stroke that develops during or 30 days after surgery. Since the publication in 2014 of the last fundamental work on the prevention of perioperative stroke, the approaches to primary and secondary prevention, diagnosis, conservative and reperfusion treatment of ischemic stroke have been seriously modified. The numerous changes have created the preconditions for a revision of existing approaches to providing care for patients with perioperative ischemic stroke. In 2021, updated documents from foreign researchers/associations on the perioperative ischemic stroke in non-cardiac and non-neurosurgical patients were published. The second part of our review presents current data on the perioperative antithrombotic prophylaxis, clinical and instrumental diagnosis, treatment and organization of care for perioperative ischemic stroke in this category of patients. The issues of using reperfusion treatment methods in non-cardiac and non-neurosurgical patients with perioperative stroke, such as systemic thrombolytic therapy and endovascular interventions, are discussed in detail, including the world experience of their “offlabel” use.
