The Influence of Cerebral Arterial Circle on Prominent Hypointense Vessel Signs in Patients With Internal Carotid Artery Occlusion

Background and PurposePrevious studies on the presence of asymmetrical prominent cortical and medullary vessel signs (APCV/APMV) and collateral circulation in patients with internal carotid artery occlusion internal carotid artery occlusion (ICAO) are rare, and the conclusions are inconsistent. Our study aimed to investigate the relationship between the presence of APCV/APMV and collateral circulation in patients with ICAO.MethodsPatients with acute ischemic stroke with ICAO were recruited in this study. All 74 patients were divided into two groups depending on the presence of APCV and APMV. The status of the cerebral arterial circle (CAC) was graded as poor or good. The poor CAC was defined as MCA was invisible. Severe stroke was defined as cerebral watershed infarction (CWI) or territorial infarction (TI). Clinical and radiological markers were compared between these two groups. Logistic regression was used to investigate the association between the APCV/APMV and clinical and radiological markers.ResultsA total of 74 patients with ICAO were enrolled. Forty-three patients (58.1%) presented with an APCV and APMV was found in 35 (47.2%) patients. Compared with patients with non-APCV, patients with APCV had a more severe stroke (P = 0.038) and had a significantly higher incidence of poor CAC (P = 0.022) than those with APCV. Patients with APMV had a more severe stroke (P = 0.001). Logistic regression showed that poor CAC was independently associated with APCV and severe stroke were independently associated with APMV.ConclusionsOur study demonstrates that poor CAC was independently associated with the presence of the APCV in patients with ICAO. Severe stroke was independently associated with the APMV.

Short Period

Pituitary apoplexy complicated by internal carotid artery occlusion was encountered in a patient with surprisingly moderate symptoms at presentation. For a short period of watchful waiting, primary collaterals obscured the emergent need for decompressive surgery, which after the sudden onset of neurological deterioration fortunately salvaged imminent cerebral infarction. Although a few similar cases have been described previously, the importance of collateral circulation has been left virtually without comment, while contrasting treatment strategies and high mortality rates suggest further case reports are warranted. Notably, a symptoms-based management seems likely to be insufficient in these rare situations, while our experience indicate early surgery could be judicious to consider.

Abstract A case of progressive hydrocephalus as a complication of spontaneous cervical internal carotid artery occlusion in a child is presented. This problem has not been reported previously. The diagnosis and management of this condition are greatly facilitated by computed tomographic scanning.
