Abstract

Objectives: The impact of artery geometry on intracranial atherosclerosis (ICAS) is unclear. To investigate the association between local artery geometry characteristics and middle cerebral atherosclerotic stenosis.

Methods: This was a case-control study. ICAS patients with more than 50% stenosis in one M1 pre-bifurcation segment but no significant stenosis on the other side were included. The stenosis degree, diameter, length, angle, and morphology (straight-shape, U-shape, and S-shape) of the M1 pre-bifurcation segments were measured by using digital subtraction angiography (DSA) combined with computed tomography angiography (CTA) and 3D reconstruction imaging. The geometry characteristics on both sides were compared. The conditional multivariate Logistics regression was used to investigate the association between stenotic sides and the geometry characteristics.

Result: A total of 133 patients, 266 M1 pre-bifurcation segments, were included. Compared with non-stenotic sides, stenotic sides showed smaller diameters (2.873 ± 0.456 mm vs. 2.993 ± 0.360 mm, P = 0.002) and larger tortuosity index (7.61% vs. 6.45%, P = 0.048). The S-shape M1 pre-bifurcation segment was independently associated with the stenotic sides (OR = 3.509, 95% CI 1.176-10.468, P = 0.024). The stenotic side was worse fitted to Murray's law (mean square error 0.326 vs. 0.313).

Conclusions: The morphology of the M1 pre-bifurcation segment was associated with middle cerebral atherosclerotic stenosis.

期刊介绍： 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.
