To promote vessel wall regeneration, a scaffold of cellulose porous bead (CPB) was used as a material for aneurysm embolization. A rat external carotid artery (ECA) aneurysm model was created, and a single CPB with a diameter similar to the diameter of the ECA was placed in the aneurysm. The layer of regenerating αSMA-positive spindle cells at the aneurysm neck orifice was recognized as early as 2 weeks after implantation of the CPB, and maintained its thickness by 6 months. A monolayer of factor VIII-positive cells appeared at the neck at 2 weeks, and covered the entire neck by 6 months. CPBs might be appropriate as an embolization material for inducing vessel wall regeneration at the neck of an aneurysm., 研究課題/領域番号:15K10295, 研究期間(年度):2015-04-01 - 2018-03-31, 出典:研究課題「多孔質足場を用いた動脈瘤開口部の新生血管壁構造の誘導実験」課題番号15K10295 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K10295/15K10295seika/)を加工して作成, 金沢大学附属病院脳神経外科}, title = {多孔質足場を用いた動脈瘤開口部の新生血管壁構造の誘導実験}, year = {2018} }
