The relation of vertebral artery occlusion and intravertebral cleft: a prospective magnetic resonance angiography study
Purpose
To detect the relationship between the vertebral artery occlusion and the intravertebral cleft (IVC).
Methods
A prospective evaluation of the vertebral segmental artery condition from the T10 to L4 with the magnetic resonance angiography (MRA) was performed in 44 osteoporosis vertebral compression fracture (OVCF) patients. The artery condition was divided into the patency, narrow, occlusion. The lesion segmental occlusion rate (LSOR) and the total occlusion rate (TOR) was calculated. The relation of the vertebral artery occlusion and the IVC formation was assessed with the univariate analysis.
Results
LOSR was 15.34% and TOR was 15.2%. The segmental arteries of the unfractured vertebrae had higher occlusion rate in thoracolumbar levels than non-thoracolumbar levels. Neither lesion levels arteries occlusion nor the total segmental arteries occlusion was associated with the IVC.
Conclusions
Vertebral compression fracture did not lead to the segmental artery occlusion. The segmental artery occlusion more likely happened in the thoracolumbar levels. The segmental artery occlusion did not lead to the IVC.
