Stent-graft induced new entry tears after type B aortic dissection: how to treat and how to prevent?

Progress of aortic disease after stent-graft treatment of aortic dissection includes the risk of stent graft-induced new entry (SINE). In this paper we review the incidence and mechanisms thought to be responsible for retrograde ascending and distal SINE after thoracic endovascular aortic repair (TEVAR) for type B dissection, and examine potential techniques for treatment and prevention. Although the risk of proximal SINE is low, the fatality of this complication requires vigilance in patients who develop new onset symptoms in the early period after TEVAR treatment. Careful technique, minimal oversizing, and use of disease specific stent grafts may reduce the risk for proximal SINE. Distally, SINE is more frequently seen during follow-up in patients treated for chronic dissection. The most important risk factor is oversizing of the stent-graft compared to the true lumen distal landing zone. Development of new disease specific stent grafts with reduced distal radial force may reduce the risk for distal SINE.
