Timely recanalization during endovascular procedures for acute ischemic stroke can be challenging in cases with large clot burden, such as those encountered in the terminal internal carotid T- or L-type occlusion.
A novel but simple technique to achieve fast reduction in clot burden in stroke patients with occlusion of the internal carotid artery termination is described where manual suction using a 60-ml syringe applied through an 8-F balloon guide catheter positioned in the cervical carotid vasculature with proximal flow arrest allows subsequent revascularization of the residual middle cerebral artery clot.
The use of manual suction through a balloon-tipped guide catheter in internal carotid artery L- or T-type occlusion is illustrated. This resulted in a significant reduction of the clot burden and facilitated further interventions leading to full recanalization.
Manual suction using a 60-ml syringe through a balloon guide catheter is a useful and feasible technique that facilitates thrombectomy of large burden cerebral clots.
在急性缺血性脑卒中的血管内治疗过程中，对于血栓负荷较大的病例，如颈内动脉末端 T 型或 L 型闭塞，及时再通可能具有挑战性。
描述了一种新颖但简单的技术，用于在颈内动脉末端闭塞的脑卒中患者中快速降低血栓负荷。通过将近端血流阻断的位置置于颈内血管中的 8-F 球囊引导导管内的 60ml 注射器手动抽吸，可对残余大脑中动脉血栓进行后续再通治疗。
通过球囊引导导管对 L 型或 T 型颈内动脉闭塞进行手动抽吸的应用进行了说明。这导致血栓负荷的显著降低，并促进了进一步的干预，从而实现了完全再通。
通过球囊引导导管使用 60ml 注射器进行手动抽吸是一种有用且可行的技术，可促进大负荷脑血栓的血栓切除术。
