Self-expandable aortic stent-grafts for treatment of descending aortic dissections

Diretrizes para o tratamento cirúrgico das doenças da aorta da Sociedade Brasileira de Cirurgia Cardiovascular

“…Recently, an interesting contribution was proposed by the group of the Escola Paulista de Medicina, (Paulista Medical School) with the use of percutaneous self-expanding stents, in all cases of descending aorta dissections. Palma et al [93] treated 70 patients with type-B dissections (60% of which were true dissections and 40% corresponded to intramural hematomas or penetrating ulcers), with implantation by the femoral artery of polyester-covered endoprostheses (Braile Biomedica®), under general anesthesia, systemic heparinization and induced hypotension. The procedure was considered a success in 65 (93%) patients, with the exclusion of the false lumen documented using aortography.…”

“…Palma e cols. 96 submeteram 70 pacientes com dissecções tipo B (das quais 60% eram dissecções verdadeiras e 40% correspondiam a hematoma intramural ou a úlceras penetrantes), ao implante por via femoral de endopróteses recobertas de poliéster (Braile Biomédica®), sob anestesia geral, heparinização sistêmica e hipotensão induzida. O procedimento foi considerado um êxito em 65 (93%) pacientes, através da documentação de exclusão da falsa luz à aortografia, tendo sido necessária em 5 (7%) a conversão para cirurgia; não houve ocorrência de paraplegia ou óbito.…”

Initial and Midterm Results for Repair of Aortic Diseases With Handmade Stent Grafts

“…However, establishing a hook, barb, or bare stent in the landing zone to prevent an endoleak or migration [32][33][34] may potentially injure the aortic wall or occlude an aortic branch. Although the feasibility of EVR for aortic dissections using simple cylindrical SGs has been reported, [35][36][37][38] transformation, kinking, and fragility of the true lumen are associated with the risk of intima damage or endoleak. We encountered endoleaks in the case of aortic dissections and prosthetic proximal landing zones.…”
