Endovascular treatment of ruptured dissecting aneurysms aimed at occlusion of the dissected site by using Guglielmi detachable coils

Abstract: At the present time, endovascular occlusion of the dissected site is a safe, minimally invasive, and reliable treatment for dissecting aneurysms when a test occlusion is tolerated and adequate collateral circulation is present.

“…TI-weighted images may show high signal intensity within the dissected vessel wall, but the signal intensity of the hematoma changes with chronological age of the bleed and is seen in a minority of cases. While Hirai (11) et al Endovascular treatment for dissecting aneurysms of the posterior circulation and specifically for PCA dissecting aneurysms has been described (17,22,23,24). Although endovascular treatment has only been performed in a small number of patients, it seems to offer a reasonable alternative to surgery.…”

“…Na quase totalidade das dissecções das artérias vertebrais o hematoma intramural forma-se entre a lâmina elástica interna e a camada média. Raramente a dissecção envolve a camada subadventícia e, quando isto acontece, pode ocorrer ruptura para o espaço subaracnoideo resultando em HSA 2,[4][5][6][7][8][9][10][11][12][13] . Segundo Yamaura 10 , 28% dos aneurismas da circulação posterior, que evoluem com HSA, são lesões aneurismáticas dissecantes.…”

“…Devido à sua localização, sendo a maioria dos aneurismas distal à PICA e próximo à linha média, há dificuldade de abordagem cirúrgica, havendo aumento da morbidade por paralisia de nervos cranianos baixos. Ainda como complicação intraoperatória, a ruptura do aneurisma pode ocorrer espontaneamente ou por manipulação, em virtude da espessura adelgaçada da camada adventícia 10 . O tratamento cirúrgico por abordagem endovascular tem sido uma opção recentemente utilizada para estes aneurismas, através de técnicas endovasculares com uso de balões destacáveis, angioplastia transluminal, e oclusão (ou "trapping" interno) com molas (coils) 4,6,8,10 .…”

“…10,14,17) Endovascular occlusion has been accepted as a safe, minimally invasive, and reliable treatment for ruptured dissecting aneurysms. 3,6,7,14,18) Occlusion of the entire affected area is the most ideal and most complete treatment for such lesions. 14) Several studies suggest that the radiographic findings of a ruptured VA dissection indicate dynamic changes in acute stage.…”
