はじめに 弓部大動脈置換術におけるJ Graft Frozenix(以下,Frozenix:日本ライフライン社,東京)の有用性が報告1)される一方,合併症も散見される2).われわれは,Stanford A型急性大動脈解離術後にFrozenixの狭窄をきたした症例を経験したので報告する.
This is the case of 50s female with Stanford type A acute aortic dissection who underwent emergent total arch replacement. The aortic arch was transected just distal to the left subclavian artery, followed by the insertion of J Graft Frozenix into the descending aorta. No blood pressure gradient was observed between the radial and femoral arteries immediately after the operation. Nevertheless, intermittent claudication was observed after a week. Ankle-brachial index (ABI) measurement was calculated at 0.7 in both legs. Computed tomography (CT) revealed a kinking of the non-stented part of the endograft. Subsequently, thoracic endovascular aortic repair (TEVAR) was performed. As a result, ABI measurement normalized and lower limb pain disappeared. Three years after, CT showed that the endograft expanded satisfactorily. In deployment of J Graft Frozenix, the non-stented part should be kept as short as possible. For kinking, TEVAR should be considered the initial treatment option.
