Prominence of deep medullary veins associated with the risk of stroke in unilateral chronic internal carotid artery occlusion patients.
Purpose: To clarify the relationship between deep medullary veins (DMV) and risk of post-discharge stroke in chronic internal carotid artery occlusion (CICAO) patients.
Methods: Hospitalized patients were divided into CICAO patients and control group without cerebral artery occlusion. SWI assessed DMV prominence in both cerebral hemispheres on a 0-3 scale. If the DMV scores of both hemispheres were consistent, DWV was not prominent (DMV-). Otherwise, DWV was prominent (DMV+) in the higher score hemisphere. In DMV + patients with CICAO, if the DMV score in the ipsilateral hemisphere of CICAO was higher than the contralateral hemisphere, DMV + was DMVi, otherwise, DMV + was DMVc.
Results: 110 unilateral CICAO patients and 75 control group patients were finally enrolled. 89CICAO patients and 5 control group patients were DMV+. In CICAO patients, 54 were DMVi patients and 35 were DMVc patients. Binary logistic regression analysis showed that CICAO was the independent risk factor of DMV+ (OR: 75.23; 95%CI :25.58-240.07; P < 0.001). Compared with DMVc patients, DMVi patients had a lower proportion of simultaneous primary and secondary collaterals activation(P = 0.034), decreased perfusion in the CICAO ipsilateral hemisphere (P < 0.001) and higher DMV scores in the prominent hemisphere (P = 0.012). Cox regression showed that the risk of stroke events post discharge in DMVi patients was higher than that in DMVc patients (HR: 4.68; 95%CI: 1.02-21.50; P = 0.047).
Conclusion: CICAO is an independent risk factor for DMV. The collateral circulation and cerebral perfusion are related to DMVc. DMVc predictes a lower risk of stroke in CICAO patients post discharge.

Neuroradiology aims to provide state-of-the-art medical and scientific information in the fields of Neuroradiology, Neurosciences, Neurology, Psychiatry, Neurosurgery, and related medical specialities. Neuroradiology as the official Journal of the European Society of Neuroradiology receives submissions from all parts of the world and publishes peer-reviewed original research, comprehensive reviews, educational papers, opinion papers, and short reports on exceptional clinical observations and new technical developments in the field of Neuroimaging and Neurointervention. The journal has subsections for Diagnostic and Interventional Neuroradiology, Advanced Neuroimaging, Paediatric Neuroradiology, Head-Neck-ENT Radiology, Spine Neuroradiology, and for submissions from Japan. Neuroradiology aims to provide new knowledge about and insights into the function and pathology of the human nervous system that may help to better diagnose and treat nervous system diseases. Neuroradiology is a member of the Committee on Publication Ethics (COPE) and follows the COPE core practices. Neuroradiology prefers articles that are free of bias, self-critical regarding limitations, transparent and clear in describing study participants, methods, and statistics, and short in presenting results. Before peer-review all submissions are automatically checked by iThenticate to assess for potential overlap in prior publication.
