Stroke after cardiac surgery: short- and long-term outcomes Jorge D Salazar, MD, Robert J Wityk, MD, Maura A Grega, MSN, Louis M Borowicz, MS, John R Doty, MD, Jason A Petrofski, MD, William A Baumgartner, MD The Annals of Thoracic Surgery Volume 72, Issue 4, Pages 1195-1201 (October 2001) DOI: 10.1016/S0003-4975(01)02929-0
Fig 1 Example of embolic (large artery) cerebral infarction. Computer tomography (CT) in a patient with complete right middle cerebral artery territory infarction (within arrows). Embolic infarctions involve a well-defined vascular territory and characteristically have a triangular appearance on CT.

Fig 2 Examples of watershed (border-zone) cerebral infarction. Computed tomography in a patient with multiple watershed (border-zone) infarctions (A and B). (A) The arrow indicates a frontal lobe, middle cerebral artery-anterior cerebral artery (MCA-ACA) border-zone infarction. (B) The arrow indicates a parietal/occipital, middle cerebral artery-anterior cerebral artery, posterior cerebral artery (MCA-ACA-PCA) border-zone infarction. Watershed infarction is defined as an infarct between vascular territories. The term “watershed” infarct refers to the neuroimaging characteristics of the infarct and does not necessarily imply mechanism of stroke.
