Key result
Oversized compliant balloon use during the STABILISE technique causes fatal infrarenal aortic rupture.
Why the study?
The STABILISE technique shows promising results for treating type B aortic dissections, but the potential exists for fatal adverse effects.
Does the STABILISE technique using a compliant balloon increase the risk of aortic rupture in patients with complicated type B aortic dissection?

Does the STABILISE technique using a compliant balloon increase the risk of aortic rupture in patients with complicated type B aortic dissection?
The STABILISE technique poses a serious risk of aortic rupture, emphasizing that operators should use a semi-compliant balloon sized to the smallest total aortic diameter.
Oversized compliant balloons in STABILISE may cause rupture; leaves open whether sized semi-compliant alternatives improve safety.
The STABILISE (stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair) technique has shown promising results for treating type B aortic dissections, but the potential exists for fatal adverse effects. We present a case of infrarenal aortic rupture while using a compliant balloon to balloon mold the true lumen inside previously placed bare metal stents during the STABILISE technique. Caution is advised for providers who wish to perform the STABILISE technique, and we recommend using a semi-compliant balloon sized to the smallest total aortic diameter to mitigate the risk of rupture.

Hsu et al. (2023) conducted a case report in Complicated type B aortic dissection (n=1). STABILISE technique with compliant balloon was evaluated on Aortic rupture. Use of an oversized compliant Tri-Lobe balloon during the STABILISE technique resulted in an infrarenal aortic rupture, highlighting the need to use properly sized semi-compliant balloons.
