- These areas are particularly susceptible to saccular aneurysms.
- Saccular aneurysms, also known as berry aneurysms, appear as a round outpouching and are the most common form of cerebral aneurysm.
- Moreover, he wrote : 4 books on epidermoids ( 1957 ), Cranio cerebral topography ( 1959 ), Acoustic neuromas ( 1970 ) and Ruptured saccular aneurysms ( 1987 ).
- Saccular aneurysms tend to have a lack of tunica media and elastic lamina around its dilated location ( congenital ), with wall of sac made up of thickened hyalinized intima and adventitia.
- Saccular aneurysms are spherical in shape and involve only a portion of the vessel wall; they vary in size from 5 to in diameter, and are often filled, either partially or fully, by a thrombus.
- Other factors are positively associated with the regression of aneurysms, including being younger than a year old at the onset of Kawasaki disease, fusiform rather than saccular aneurysm morphology, and an aneurysm location in a distal coronary segment.
