RESUMO
The authors present a surgical approach to type III and IV Crawford aneurysms that does not need total aortic clamping, which allows the more objective prevention of direct ischemic damage, as well as its exclusion by the endoprosthesis implantation, shunting the flow to the synthetic graft.
Os autores apresentam uma abordagem cirúrgica aos aneurismas do tipo III e IV de Crawford em que não é necessário o pinçamento total da aorta, o que permite a prevenção do dano isquêmico direto de forma mais objetiva, assim como sua exclusão por implante de endoprotese desviando o fluxo para o enxerto sintético

Celiac artery aneurysms are rare, their incidence being reported as only 4% of all visceral artery aneurysms. Atherosclerosis and medial degenerative changes are recognized main pathogenesis. They are usually asymptomatic and diagnosed incidentally, but the mortality rate of ruptured celiac artery aneurysm is approximately 80%. So one should give an aggressive surgical aid to the patients. We report 2 cases of celiac artery aneurysm which were successfully treated by elective aneurysmorrhaphy and anerysmectomy with aortoceliac bypass graft.

Objective Endovascular tubular stent grafting has emerged as an alternative therapeutic modality for patients with aortic dissections. However, its application has been limited to the descending thoracic aorta distal to the origin of the left subclavian artery. The initial clinical experience of endovascular branched stent graft repair for aortic arch dissections involving the left subclavian artery was reported. Methods From February 2004 to January 2005, the endovascular branched aortic stent-grafts made by Beijing YuHengJia SciTech Co. were applied in 42 patients with Stanford type B aortic dissection with the entry tears just beyond (
