Background
Iatrogenic aortic dissection is a rare and fatal complication. Its treatment was challenging and controversial especially in patients with previous cardiac procedure. This study aimed to present the case of a patient with aortic dissection after previous open cardiac surgery who was successfully treated by in situ laser fenestration for revascularization of aortic arch.
Case presentation
A 65-year-old man suffered severe aortic and mitral valve regurgitation was treated by open cardiac aortic valve replacement (biological valve, Edwards) and mitral valve repair. During the sixth-month follow-up, computed tomography angiography (CTA) scan revealed an aortic dissection that extended from the ascending aorta to both femoral arteries. After stabilized by medical treatment, the patient was treated by endovascular stent-graft implantation and in situ laser (holmium laser, energy: 0 5 J, frequency: 5 Hz.) fenestration for revascularization of aortic arch in our one-stop hybrid operating room. The patient recovered without any clinical complication and was discharged 5 days after the procedure.
Conclusions
Our work suggested that in situ laser fenestration for revascularization of aortic arch is a feasible, effective, and safe treatment in patients with iatrogenic aortic dissection.
