Angiographic and computed tomographic (CT) findings were compared with findings in SPECT. Hemodynamic changes in SPECT were also evaluated in 19cases after artificial embolization. Angiographic steal and low perfusion areas (LPAs) surrounding the nidus were observed in 29 cases with a nidus of over 1.0cm＾3 in volume. The size of LPA was almost same as the area of angiographic steal in 15 cases, and was larger in 14 cases. In 8 cases of the latter group, venous hypertension also seemed to cause LPAs, in addition to arterial steal. Hemodynamic changes occurred immediately after embolization. In 6 cases of 11 cases embolized with liquid emboli, new low density lesion in CT developed. However, LPAs in 8 cases including 3 of the 6 cases improved in the long term. On the other hand, only one case of 9 cases embolized with solid emboli showed newly developed low density lesion in CT. But LPAs got worse in the territory of non-embolized feeding arteries in 3 cases, and improvemet of LPAs after embolization got worse again in the long term in 4 cases. Hyperperfusion areas were seen in two cases after embolization. SPECT was useful for evaluation of the hemodynamic effect of embolizations. SPECT is safety, repeatable and useful for evaluation of cerebral hemodynamics in the patients with AVM, and is effective to treat AVMs.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"125747","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishimaki, Keiichi"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟医学会"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00182415","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00290440","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西巻, 啓一"}],"nameIdentifiers":[{"nameIdentifier":"125746","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-16"}],"displaytype":"detail","filename":"107(2)_140-156.pdf","filesize":[{"value":"7.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"107(2)_140-156.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/20339/files/107(2)_140-156.pdf"},"version_id":"c307ba2b-d9bd-4a03-859b-93aaaa040e2f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"arteriovenous malformation","subitem_subject_scheme":"Other"},{"subitem_subject":"^<123>I-IMP-SPECT","subitem_subject_scheme":"Other"},{"subitem_subject":"steal phenomenon","subitem_subject_scheme":"Other"},{"subitem_subject":"venous hypertension","subitem_subject_scheme":"Other"},{"subitem_subject":"embolization","subitem_subject_scheme":"Other"},{"subitem_subject":"脳動静脈奇形","subitem_subject_scheme":"Other"},{"subitem_subject":"盗血現象","subitem_subject_scheme":"Other"},{"subitem_subject":"静脈圧亢進","subitem_subject_scheme":"Other"},{"subitem_subject":"人工塞栓術","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"SPECT（single photon emission CT）による脳動静脈奇形症例の脳循環動態 : 血管撮影所見との比較検討及び人工塞栓術前後の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SPECT（single photon emission CT）による脳動静脈奇形症例の脳循環動態 : 血管撮影所見との比較検討及び人工塞栓術前後の変化"},{"subitem_title":"SPECT（single photon emission CT）による脳動静脈奇形症例の脳循環動態 : 血管撮影所見との比較検討及び人工塞栓術前後の変化","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1165"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-01-25"},"publish_date":"2016-01-25","publish_status":"0","recid":"20339","relation_version_is_last":true,"title":["SPECT（single photon emission CT）による脳動静脈奇形症例の脳循環動態 : 血管撮影所見との比較検討及び人工塞栓術前後の変化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:51:09.293121+00:00"}
