Stent retriever thrombectomy (SRT) is one of the most effective methods for the recanalization of acute basilar artery occlusion (ABAO). The proatlantal intersegmental artery (PIA) is a rare carotid-vertebrobasilar anastomosis. Recognition of this rare form of anastomosis is particularly important for the rapid establishment of positive blood flow in patients with ABAO. In this case, the patient had a rare, left type 1 PIA. The right vertebral artery (VA) was tenuous and did not enter the cranium. We performed a thrombectomy of the ABAO by inserting a catheter the type 1 PIA. The complete recanalization of basilar artery (BA) flow was achieved following two stent retractions; however, the patient eventually died of brain stem hemorrhage.
支架取栓术（SRT）是急性基底动脉闭塞（ABAO）再通最有效的方法之一。寰椎前段节段间动脉（PIA）是一种罕见的颈-椎基底动脉吻合。认识这种罕见的吻合形式对于ABAO患者快速建立正向血流尤为重要。在本病例中，患者有罕见的左侧1型PIA。右侧椎动脉（VA）纤细，未进入颅骨。我们通过将导管插入1型PIA对ABAO进行了取栓术。两次支架回撤后实现了基底动脉（BA）血流的完全再通；然而，患者最终死于脑干出血。
