Seeing Is Believing: Headway27 as a Highly Visible and Versatile Microcatheter with Ideal Dimensions for Stroke Thrombectomy

Introduction: Microcatheter selection is an infrequent focus of stroke thrombectomy technique evaluation. The Headway27 microcatheter strikes an excellent balance of microcatheter dimensions (156 cm length, 2.6 Fr distal OD, ID 0.027 inches) and visibility, making it ideal for stroke thrombectomy. Methods: We evaluated a prospectively maintained acute stroke thrombectomy database containing 50 consecutive cases using the Headway27 microcatheter. From the database, patient demographics, clinical and angiographic information as well as procedural technical details and complications were extracted. Results: Manual aspiration thrombectomy (MAT) was performed alone in 72% of cases, stentriever-assisted MAT was performed in 6% of cases, and a combination was used in 22% of cases. Median groin puncture to final recanalization time was 27 min and mTICI 2B/3 recanalization was achieved in 94% of cases. There were 2 intra-procedural complications, neither related to the microcatheter. In all cases, the Headway27 reached the intended target vessel: M1 (n = 4), M2 (n = 26), M3 (n = 13), P2 (n = 3), P3 (n = 1), and basilar artery (n = 3). There were no cases requiring usage of an additional or alternative microcatheter. In 45/47 cases of MAT, the reperfusion catheter tracked over the Headway to the clot/intended target; in two cases, the microcatheter was used to deploy a stentriever that then allowed the reperfusion catheter to track to the clot. Conclusion: The Headway27 microcatheter reliably facilitated rapid clot access in anterior and posterior circulation acute large vessel occlusions with no microcatheter-associated complications.
