[Efficacy of Distal Perfusion During Frozen Elephant Trunk Procedure:Continuous Perfusion Versus Intermittent Perfusion].

Purpose: To compare the effectiveness of continuous distal perfusion( CDP) with that of intermittent distal perfusion( IDP) during frozen elephant trunk( FET) procedures.

Methods: There were 54 patients in the CDP group and 15 patients in the IDP group. There were no significant differences in preoperative characteristics between the two groups, but dissection was more common in the IDP group than in the CDP group, and the maximum aneurysmal diameter was larger in the CDP group than in the IDP group.
