The collapse or compression of a thoracic endograft represents a potentially fatal complication that normally requires endovascular or open surgical correction. We present the first report of a compressed thoracic endograft that spontaneously re-expanded without surgical or endovascular intervention. The possible mechanism for the compression and re-expansion of the endograft will be discussed. The unique behavior of this endograft offers insight into an important failure modality for thoracic endografts.
