However, SAI-ICG lacks the temporal resolution for recording rapid blood flow. The authors found that SAI of saline (SAIS) via a microcatheter renders the vessels transparent because of the replacement of intravascular blood with saline. By combining SAIS with SAI-ICG, they were able to identify abnormal vessels in the bright field during the surgical treatment of spinal AVS. Furthermore, they performed slow-motion video recording of blood flow in abnormal vessels by mounting a high frame rate (HFR) digital camera on the microscope eyepiece during SAIS. In this paper, the authors present two cases of patients with spinal AVSs. The first patient had a cervical dural arteriovenous fistula, and the second had a thoracic spinal arteriovenous malformation. SAIS delineated abnormal vessels within the bright field in real time in both cases. HFR video was recorded in the second case during SAIS. The slow-motion video showed a smooth and seamless motion of the blood flow in the feeding artery, which facilitated an understanding of the blood flow direction.<\/jats:p>","DOI":"10.3171\/2018.3.spine1854","type":"journal-article","created":{"date-parts":[[2018,8,10]],"date-time":"2018-08-10T14:01:27Z","timestamp":1533909687000},"page":"576-581","source":"Crossref","is-referenced-by-count":3,"title":["Intraoperative real-time identification of abnormal vessels within the bright field by superselective arterial injection of saline and its slow-motion recording using a high frame rate digital camera during surgical treatment of spinal arteriovenous shunts: technical note"],"prefix":"10.3171","volume":"29","author":[{"given":"Shuji","family":"Hamauchi","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiya","family":"Osanai","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshitaka","family":"Seki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahito","family":"Kawabori","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michinari","family":"Okamoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazutoshi","family":"Hida","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sapporo Azabu Neurosurgical Hospital, Sapporo, Hokkaido, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyohiro","family":"Houkin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hokkaido University Graduate School of Medicine; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Vasc Surg","doi-asserted-by":"publisher","first-page":"637","DOI":"10.1016\/j.jvs.2012.02.037","article-title":"Feasibility and validation of spinal cord vasculature imaging using high resolution ultrasound","volume":"56","author":"Abd Allah F","year":"2012","unstructured":"Abd Allah F, Majidi S, Watanabe M, Chaudhry SA, Qureshi AI: Feasibility and validation of spinal cord vasculature imaging using high resolution ultrasound.
