Mechanical thrombectomy for acute occlusion of the posterior inferior cerebellar artery: A case report

Figure 1 Preoperative computed tomography angiography. A: Computed tomography angiography (CTA) revealed severe stenosis of the right internal carotid artery; B: CTA revealed the formation of mixed plaques in the left subclavian artery.

Figure 2 Digital subtraction angiography images. A: Digital subtraction angiography (DSA) showed that the left vertebral artery and posterior inferior cerebellar artery were unaffected; B: DSA showed that the left posterior inferior cerebellar artery was occluded.

Figure 3 Operating process and outcome. A: The proximal extent of the embolus was confirmed by 3MAX angiography; B: The posterior inferior cerebellar artery was unobstructed after aspiration (Thrombolysis in Cerebral Infarction level 3); C: Noncontrast computed tomography on the first day after surgery showed a low-density focus in the left cerebellum; D: Image of the embolus removed by 3MAX.

Figure 4 Images of the pathological results of the embolus. A-C: Fibrinous exudation with inflammatory cell infiltration.
