Endoleak別では, Type1が反射波に大きく変化が認められた.しかし,変化のばらつきが大きく,明らかな傾向を見出すことはできなかった.ブタでは, 3群間に有意な差はなかった.反射波は瘤作成後に極性が5例で変化したが, 3例では変化しなかった.臨床例では,反射波はステントグラフトによる治療後に極性が3例で変化したが, 2例では変化しなかった.今回の研究では,血管径の拡張により反射波の極性が変化する現象が,実証系モデルでも明らかとなった.動脈瘤の診断のみならずendoleakも早期診断しうる可能性が示唆された.臨床例でも同様の傾向がみられた.また、問題点としてデータ採取の困難さがあげられた.測定装置の改良により正確なデータ採取が可能になることが期待される.","subitem_description_type":"Abstract"},{"subitem_description":"Wave intensity change not arterial wall character, but the pressure of the arterial wall. The purpose of this present study is to clarify the change of the wave intensity between pre-, post-stentgraft deployments. The wave intensity of the circulation mock, pig, and clinical cases was measured by an ultrasound device(prosoundα7, ALOKA, Tokyo). In every three group, wave I and II did not change significantly. At pre-and post stentgraft deployment, the pole of refractory wave change in many cases of all groups. The refractory wave change by endoleak was found at the circulation mock. In this present study, the possibility of wave intensity was clarified for the aneurysm diagnosis, including the post-repair endoleak. More suitable device will be expected to measure the wave intensity.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:21591631, 研究期間(年度):2009 – 2011\n","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「ステントグラフト内挿術後のエンドリークに対する脈派解析による無侵襲診断法の確立」課題番号21591631\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-21591631/21591631seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域医学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00059643","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=60283131"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=60283131","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-21591631/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-21591631/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-21591631/21591631seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-21591631/21591631seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-02"}],"displaytype":"detail","filename":"ME-PR-OHTAKE-H-kaken 2012-4p.pdf","filesize":[{"value":"910.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-OHTAKE-H-kaken 2012-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/53360/files/ME-PR-OHTAKE-H-kaken 2012-4p.pdf"},"version_id":"622ea79e-0288-4e65-a545-837b8506cb18"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ステントグラフト内挿術後のエンドリークに対する脈派解析による無侵襲診断法の確立","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ステントグラフト内挿術後のエンドリークに対する脈派解析による無侵襲診断法の確立"},{"subitem_title":"Basic study of non-invasive examination for postoperative endoleak","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2822"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-02"},"publish_date":"2020-11-02","publish_status":"0","recid":"53360","relation_version_is_last":true,"title":["ステントグラフト内挿術後のエンドリークに対する脈派解析による無侵襲診断法の確立"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:25:50.642212+00:00"}
