Utilizing a Guiding Catheter to Improve Endovascular Therapy Outcomes for Acute Vertebrobasilar Artery Occlusion in Patients with Tortuous Vessels.

 Stable and swift placement of a guiding catheter in endovascular therapies for acute vertebrobasilar artery occlusion is often difficult because of the tortuous bends of the vertebral or subclavian artery especially in older people. The use of a delivery assist guiding catheter (DAGC) shortens the time with stable support to deliver a therapeutic treatment catheter to the target lesions. Herein, we reported the clinical and radiographic outcomes in endovascular therapies utilizing the DAGC for acute vertebrobasilar artery occlusions in actual clinical settings.
