With the availability of 3D intraoperative DSA (3D-iDSA) in hybrid operating rooms, the present study offers a contemporary comparison for rates of accuracy and discordance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>In this retrospective study of prospectively collected data, 140 consecutive patients underwent microsurgical treatment of intracranial aneurysms (IAs) in a hybrid operating room. Variables analyzed included patient demographics, aneurysm-specific characteristics, intraoperative ICGVA and 3D-iDSA findings, and the need for intraoperative clip readjustment. The authors defined the discordance rate of the two modalities as a false-negative finding that necessitated clip repositioning after 3D-iDSA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>In 120 patients, ICGVA and 3D-iDSA were used to evaluate 134 IA obliterations. Of 215 clips used, 29 (14%) were repositioned intraoperatively, improving the surgical result in all 29 patients (24%). Repositioning was prompted by visual inspection and microvascular Doppler ultrasonography in 8 (28%), ICGVA in 13 (45%), and 3D-iDSA in 7 (24%) patients. Clip repositioning was needed in 7 patients (6%) based on 3D-iDSA, yielding an ICGVA accuracy rate of 94%. Five (71%) of the ICGVA\u20133D-iDSA discordances that prompted clip repositioning occurred at the anterior communicating artery complex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>A combination of vascular monitoring techniques most often achieved correct intraoperative interpretation of complete IA occlusion and parent artery integrity. Compared with 3D-iDSA imaging, ICGVA demonstrated high accuracy. Despite the relatively low discordance rate, iDSA was confirmed to be the gold standard. Improved imaging quality, including 3D-iDSA, supports its routine use in IA surgery, obviating the need for postoperative DSA.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2018.1.jns172253","type":"journal-article","created":{"date-parts":[[2018,7,13]],"date-time":"2018-07-13T09:57:07Z","timestamp":1531475827000},"page":"1-8","source":"Crossref","is-referenced-by-count":23,"title":["Comparison of 3D intraoperative digital subtraction angiography and intraoperative indocyanine green video angiography during intracranial aneurysm surgery"],"prefix":"10.3171","author":[{"given":"Serge","family":"Marbacher","sequence":"first","affiliation":[{"name":"Department of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Itai","family":"Mendelowitsch","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Basil Erwin","family":"Gr\u00fcter","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Diepers","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, Department of Radiology, Kantonsspital Aarau, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Remonda","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, Department of Radiology, Kantonsspital Aarau, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Fandino","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"World Neurosurg","first-page":"e585","article-title":"Indocyanine green angiography for cerebral aneurysm surgery: advantages, limitations, and neurosurgeon intuition","volume":"82","author":"Abla AA","year":"2014","unstructured":"Abla AA, Lawton MT: Indocyanine green angiography for cerebral aneurysm surgery: advantages, limitations, and neurosurgeon intuition.
