Key result
Bilateral steno-occlusive atherosclerotic disease of the internal carotid artery was significantly more frequent in patients with anterior and subcortical border zone infarctions compared to posterior border zone infarctions (p=0.018).

May warrant hemodynamic assessment in border zone strokes; leaves open validation of collateral status for treatment decisions.
The emergence of brain infarction depends to a great extent on the status of collateral blood circulation and is associated with hemodynamic instability. This kind of brain infarction is usually found in border vascular zones. Infarction of borderline fields arises between vascular territories ACA and ACM or between ACM and ACP, deep paraventricular infarcts in internal border zones, wound or triangular cortical infarcts, as well as major infarctions involving the entire irrigated territory of ACM.

Mitrović et al. (2019) conducted a cross-sectional in Brain infarction in supratentorial border zones (n=30). Extracranial carotid atherosclerosis vs. Posterior border zone infarction (ACM-ACP) was evaluated on Bilateral involvement of the internal carotid artery (p=0.018). Bilateral steno-occlusive atherosclerotic disease of the internal carotid artery was significantly more frequent in patients with anterior and subcortical border zone infarctions compared to posterior border zone infarctions (p=0.018).
