Branched endovascular aortic repair of a contained rupture in chronic aortic dissection / Krónikus aortadissectio talaján kialakult tartott ruptura endovascularis mutéte elágazó grafttal

ABSTRACT

A late complication of aortic dissection is the dilatation of the weakened aortic wall. The only urgent endovascular alternative to high-risk open surgery in the treatment of postdissection aneurysms is branched endovascular aortic repair (BEVAR), which is extremely difficult due to the intimal membrane in the aorta lumen and the compressed true lumen. In this case report, we present the first application of BEVAR for aortic dissection in Hungary. Our 76-year-old male patient underwent type B aortic dissection 13 years before, for which supraaortic debranching was followed by thoracic stent graft implantation. The patient was admitted with acute chest pain associated with a con-tained rupture of a ten centimetre dilatation of the thoracoabdominal aorta. Our aortic team recommended endo-vascular surgery due to the extremely high risk of open surgery, which the patient accepted. Following selective embolization of the proximal segment of the left subclavian artery, a complex aortic intervention was performed. A new thoracic stent graft was started from the in situ thoracic graft, followed by a branched thoracoabdominal graft, the four branches of which were connected to the celiac trunk, the superior mesenteric artery and the two renal arter-ies. We also implanted a bifurcation graft under the branched graft and a left iliac bifurcation graft due to the complex dissection of the left iliac artery system. After an uneventful procedure, the patient was discharged home on the fourth postoperative day.
