Frozen elephant trunk における復元弾性力―Matsui-Kitamura ステント対J Graft Openステントグラフト
2020
Objectives:We examined the spring back force (SBF) in the frozen elephant trunk technique between patients receiving a Matsui-Kitamura stent (M group) or a J Graft Open Stent Graft (J group). Methods:There were 11 cases in the M group and 10 cases in the J group. For all cases, we performed computed tomography( CT) scan and measured distal arch angle( DAA) and stent graft angle (SGA). Results:There was no difference between groups with regards to patient characteristics. The insertion graft length[155±19 mm (M group) versus 138±17 mm (J group)]was significantly longer in the M group( p<0.05). In the J group, the SGA at 1 and 2 years postoperatively( 105°±18.5° and 114°±19.1°, respectively) were significantly increased compared to that at 1 month postoperatively (99.9°± 18.7°). In addition, the SGA in the J group was significantly larger than that in the M group during the postoperative period. Conclusions:The SBF in the J group was thought to be significantly larger than that in the M group. SBF was thought to be associated with the stent frame characteristic.
