Owing to the excellent recanalization rate of endovascular treatment, new outcome predictors are required for patients with acute stroke, who have sufficient recanalization. In this study, the effects of recanalization therapy on occluded arteries in patients with acute stroke were investigated using high-resolution vessel wall imaging.
Twenty-nine patients with stroke were included in the study. High-resolution vessel wall imaging was performed on patients with acute stroke and adequate postrecanalization results. We characterized the postrecanalization arterial wall changes as concentric enhancements and plaques and examined the associations of the postrecanalization changes with procedural factors and neurological outcomes.
The most frequent high-resolution vessel wall imaging finding was concentric enhancement, which was associated with thrombectomy procedural factors such as the number of procedures and the type of device. Concentric enhancements were associated with hemorrhagic transformation, whereas plaque was not associated with procedural details.
The use of high-resolution vessel wall imaging after successful recanalization can provide information about postrecanalization arterial wall changes and clinical outcomes.
由于血管内治疗具有出色的再通率，对于已实现充分再通的急性卒中患者，需要新的预后预测指标。在本研究中，我们使用高分辨率血管壁成像技术，研究了再通治疗对急性卒中患者闭塞动脉的影响。
本研究纳入了29例卒中患者。对急性卒中且再通结果良好的患者进行了高分辨率血管壁成像。我们将再通后的动脉壁变化特征描述为同心强化和斑块，并研究了再通后变化与手术因素及神经学预后之间的关联。
高分辨率血管壁成像最常见的表现是同心强化，其与血栓切除术的手术因素有关，如手术次数和器械类型。同心强化与出血性转化相关，而斑块与手术细节无关。
成功再通后使用高分辨率血管壁成像可提供有关再通后动脉壁变化及临床预后的信息。
