Laser Fenestration for Treatment of a Complicated Chronic Type B Aortic Dissection

Vasc Endovascular Surg. 2018 Apr;52(3):212-217. doi: 10.1177/1538574417749401.


We report a case of a complex chronic type B aortic dissection treated by thoracic endovascular aortic repair and laser fenestration of the false septum to preserve flow to branch vessels originating from both the true and false lumen. Dissections complicated by thoracoabdominal aneurysmal degeneration with critical organs being perfused by branches arising from both true and false lumens are rare and leave limited options for repair. Despite advancements in endovascular techniques, fenestration remains one of the only means of preserving flow to both the true and false lumens and thus was necessary in the management of our patient. This novel procedure allows complex aortic dissections to be addressed endovascularly, which increases the flexibility and management of this challenging problem that previously required an open repair with significant morbidity.

Keywords: aortic dissection; fenestration; thoracic endovascular aortic repair.
