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", "download_preview_message": "", "file_order": 0, "filename": "111(8)_496-508.pdf", "filesize": [{"value": "4.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 4700000.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/45212", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-12-22"}, "publish_date": "2016-12-22", "publish_status": "0", "recid": "17213", "relation": {}, "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_shared_id": null}
