Blister aneurysms
Journal Title: Journal of Neurological Sciences-Turkish - Year 2009, Vol 26, Issue 2
Abstract
The majority of saccular cerebral aneurysms arise at arterial branchings; those arising elsewhere are rare. Blister aneurysms are elusive and technically challenging rare lesions characterized by a hemispherical shape and fragile walls for both neurosurgeon and endovascular radiologist to treat. Blister aneurysms also exhibit rapid change in size and morphology in followup angiograms. Small size of blood-blister aneurysm and atypical location may result in incomplete visualization of these lesions. Therefore, multiple oblique views are essential during angiography. The weak nature and small size of blister aneurysms with a broad neck renders endovascular treatment technically challenging. Wrapping with cellulose fabric (Bemsheet) and holding clipping technique could be chosen as the optimal surgical modality for prevention of rebleeding from these lesions.
