Introduction Patients with acute intracranial large vessel occlusions (LVO) in the drip‐and‐ship model are transferred from an outside hospital (OSH) to a comprehensive stroke center (CSC) after receiving thrombolysis. In our practice, while most of these patients go directly to the angiography suite (DTA), some of them spontaneously recanalize and may not need mechanical thrombectomy (MT). We aim to assess the impact of transport modality on the efficacy of tPA‐induced recanalization by assessing rates of groin puncture, MT, and clinical outcomes. Methods We retrospectively evaluated 270 patients from 2020‐mid 2022 with either confirmed or suspected LVO in our healthcare network who received tPA at an OSH and were transported by either air or ground transport to our spoke hospital (CSC) with the intention of receiving MT. We compared baseline characteristics and then applied linear regression with propensity score matching to compare the air and ground groups. Between the two groups, we looked at the difference in the rates of change in NIHSS between OSH and TTH (delta NIHSS), groin puncture rates, rate of receiving mechanical thrombectomy (MT), rate of angiography alone without MT, and modified Rankin Scale (mRS) at 90 days. Results Of the 270 patients evaluated, 1 patient was excluded due to missing transport modality. 130 (48.33%) were transferred by ground transport and 139 (51.67%) by air. Baseline characteristics were similar between the air and ground groups with the exception of OSH NIHSS which was higher in the air group (13.59±8.3 vs. 10.4±7.81, p |
