Background: Endovascular therapies (EVTs) are useful for treating cerebrovascular disease. There are few data about the availability of such services at primary stroke centers (PSCs). Our hypothesis was that some of these services may be available at some PSCs. Methods: We conducted an internet-based survey of hospitals certified as PSCs by the Joint Commission. The survey inquired about EVTs such as intra-arterial (IA) lytics, IA mechanical clot removal, coiling of aneurysms, and cervical arterial stenting, physician training, coverage models, hospital type, and outcomes. Chi-square analyses were used to detect differences between academic and community PSCs. Results: Data were available from 352 PSCs, of which 75% were community hospitals, 23% academic medical centers, and 80% were non-profit; almost half (48%) see 300 or more patients annually with ischemic stroke. A majority (60%) provided some or all EVTs on site, while 29% had none on site and no plans to add them. Among the respondents offering EVTs, 95% offered stenting of neck vessels, 86% IA lytics, 80% IA mechanical, and 74% aneurysm coiling. The majority (>55%) that did offer such services provided them 24/7/365. Most endovascular coverage was provided by interventional neuroradiologists (60%), fellowship trained endovascular neurosurgeons (42%), and interventional radiologists (41%). The majority of hospitals (81%) did not participate in an audited national registry. Conclusions: A variety of EVT services are offered at many PSCs by interventionalists with diverse types of training. The availability of such services is clinically relevant now with the proven efficacy of mechanical thrombectomy for ischemic stroke.
