Abstract |
Objective Aneurysms at nonbranching sites in the supraclinoid internal carotid artery (ICA), known as blood blister-like aneurysms (BBA) or ICA anterior or dorsal wall aneurysms, are not well understood. Blood blister-like aneurysms carry a high rate of morbidity and mortality. The authors analysis 7 cases of BBA treated with reconstructive endovascular methods.
Methods Consecutive 7 patients of ruptured BBAs (6 female and 1 male; mean age 51 years) were treated at the Kangbuk Samsung Hospital between January 2007 and December 2011. Treatment methods and outcomes were analyzed.
Results All 7 BBAs were initially treated with stent-assisted coil (SAC) embolization. This was followed by a second stent insertion using the stent-within-stent (SWS) technique in 2, covered stent placement in 2, and SAC embolization alone in 3. All 3 patients who underwent SAC alone had good outcome but regrowth of 1 patient retreated with covered stent. One of 2 patients who received covered stent had excellent outcome but 1 patient expired due to rebleeding during procedure. All 2 patients of SWS had good outcomes and complete resolution.
Conclusion In the present study, reconstructive endovascular treatment for BBA prevented rebleeding without sacrifice of the ICA. In patients of BBA, the SWS and covered stent techniques can be considered an alternative methods for prevent rebleeding and regrowth. |
