Congestive heart failure due to excessive shunt flow is one of the complications of this procedure. We experimented with a new technique in which the ePTFE was stenosed by an absorbable material and the shunt flow was decreased to prevent excessive flow in the acute postoperative stage. Left modified Blalock-Taussig shunts using 5mm thin-walled ePTFE tubes were created in 9 beagle dogs. In group A (n=3) and group B (n=3), the shunts were pinched by polydioxanone absorbable clips and the shunt flow was decreased. In group C (n=3), the shunt was not pinched. At 4 weeks after the operation, in group A, the pinched site was dilated by means of balloon angioplasty. At 4 weeks after the operation, the dogs in group B were sacrificed and the grafts were removed. In groups A and C, at 12 weeks after the operation, the dogs were sacrificed and the grafts were removed. In group A, when the shunts were pinched by clips, a rate of decrease in the shunt flow were 80.0, 66.8 and 78.4%, respectively. Balloon angioplasty dilated the pinched sites completely and a rate of increase in the shunt flow were 54.1, 33.2 and 30.7%, respectively. In group A, light microscopic examination of the grafts showed that the lumens wete covered with a pseudointima organized by fibrin and cellulofibrous tissues. In group B, these sites were covered with a fibrin layer with leukocytes at the pinched sites. In group C, the lumens were covered with a pseudointima organized by cellulofibrous tissues in the middle of each graft. The extent of pseudointimal thickening was greater in groups A and B than in group C. In conclusion, a staged increase in shunt flow is feasible using this technique and prevents excessive shunt flow after modified Blalock-Taussig operation. However, further investigation is needed to prevent pseudointimal hyperplasia and a delay in healing mechanism of ePTFE tube.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"108787","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Namura, Osamu"}]}]},"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":"名村, 理"}],"nameIdentifiers":[{"nameIdentifier":"108786","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":"2019-08-08"}],"displaytype":"detail","filename":"111(8)_496-508.pdf","filesize":[{"value":"4.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"111(8)_496-508.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/17213/files/111(8)_496-508.pdf"},"version_id":"a020f0c6-af52-48f0-8362-9a464ffbc734"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"modified Blalock-Taussig operation","subitem_subject_scheme":"Other"},{"subitem_subject":"excessive shunt flow","subitem_subject_scheme":"Other"},{"subitem_subject":"polydioxanone absorbable clip","subitem_subject_scheme":"Other"},{"subitem_subject":"balloon angioplasty","subitem_subject_scheme":"Other"},{"subitem_subject":"Blalock-Taussig 手術変法","subitem_subject_scheme":"Other"},{"subitem_subject":"過剰短絡流量","subitem_subject_scheme":"Other"},{"subitem_subject":"ポリディオキサノン吸収性クリップ","subitem_subject_scheme":"Other"},{"subitem_subject":"バルーン血管形成術","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":"Modified Blalock-Taussig手術における短絡流量の段階的増加法に関する実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Modified Blalock-Taussig手術における短絡流量の段階的増加法に関する実験的研究"},{"subitem_title":"Modified Blalock-Taussig手術における短絡流量の段階的増加法に関する実験的研究","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1117"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-12-22"},"publish_date":"2016-12-22","publish_status":"0","recid":"17213","relation_version_is_last":true,"title":["Modified Blalock-Taussig手術における短絡流量の段階的増加法に関する実験的研究"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:48:36.925289+00:00"}
