Increased arterial stiffness is associated with an increased risk of cardiovascular events such as myocardial infarction, hypertension, heart failure, and stroke. [ 3 ] [ 4 ] [ 5 ] The World Health Organization identified cardiovascular disease as the leading cause of death globally in 2019.
The veins of the brain, both the superficial veins and the deep venous system, empty into the dural venous sinuses, which carry blood back to the jugular vein and thence to the heart. In cerebral venous thrombosis, blood clots usually form both in the veins of the brain and the venous sinuses.
Vasospasm is the major cause of Prinzmetal's angina. Cerebral vasospasm may arise in the context of subarachnoid hemorrhage as symptomatic vasospasm (or delayed cerebral ischemia), where it is a major contributor to post-operative stroke and mortality.

The management of ATE depends on the location and severity of the ischemia and the underlying etiology. The main goals of ATE management are to restore blood flow, prevent further thrombosis, and treat the underlying cause. The treatment options for ATE include antithrombotic therapy, revascularization procedures, and risk factor modification.
