Treatment of patients presenting with type I aortic dissection is known to be a surgical challenge. The Djumbodis bare metal stent was developed to ease the burden of a reconstructive intervention on the aortic arch, to decrease the duration of the operation, and to minimize complications associated with artificial circulation. Currently, insufficiently explored remains the problem of complications occurring due to the technological fatigue of the metal and possible stent migration.

Described herein is a clinical case report regarding migration of a Djumbodis stent, diagnosed 6 months after implantation for DeBakey type I acute aortic dissection. We revealed dislocation of the stent’s distal portion with fenestration of the membrane of the true channel and perfusion of the false channel, as well as fractured fragments of the stent. The patient underwent repeat «open» intervention.

KEY WORDS: aortic dissection, bare metal stent, hybrid operations, repeat interventions.
