Results of Endografting of the Aortic Arch in Different Landing Zones

摘要: Introduction. Endovascular approach to the aortic arch is an appealing solution for selected patients. Aim of this study compare technical and clinical success recorded in different anatomical settings endografting disease. Methods. Between June 1999 October 2006, among 178 patients treated at our Institution thoracic aorta disease with a stent-graft, was involved 64 cases. According classification proposed by Ishimaru, ‘‘zone 0’’ 14 cases, 1’’ 12 cases 2’’ 38 A hybrid surgical procedure supraortic debranching revascularization performed 37 obtain adequate proximal landing zone. Results. ‘‘Zone (14 cases). Proximal neck length: 44 � 6 mm. Initial 78.6%: 2 deaths (stroke), 1 type Ia endoleak. At mean follow-up 16.4 11 months midterm 85.7%. (12 28 5 66.7%: 0 deaths, 4 endoleaks. 16.9 17.2 75.0%. (38 cases) 30 84.2%: (1 cardiac arrest, multiorgan embolization), 3 endoleaks, case open conversion. Two delayed transitory paraparesis/paraplegia were observed. 28.0 89.5%. Conclusions. Total aneurysms allowed longer zone lower incidence endoleak, however higher risk cerebrovascular accident The relatively high adverse events could be associated shorter neck, therefore reserved unfit sternotomy. In discovered after satisfactorily positioned endograft arch, rate spontaneous resolution within first high.
