Case report demonstrates semi-branched stent-graft deployment for type 1a endoleak after failed EVAR, highlighting an alternative combining fenestrated and branched repair.
Endovascular techniques are advancing with the change of treatment paradigm for abdominal aortic aneurysms. Fenestrated EVAR (fEVAR) and branched EVAR (bEVAR) are used for complex aortic aneurysm repair. Both fEVAR and bEVAR have their own advantages and disadvantages. Semi-branches are a new feature that attempt to combine the advantages of both fEVAR and bEVAR.
