fusiform circumferential aneurysm - ✔✔An outpouching or widening of an artery or a vein that is
shaped like a spindle.
fusiform succular aneurysm - ✔✔also called "berry" aneurysms because they look like berries, are
the most common type of brain aneurysm. have a "neck" that connects the aneurysm to its main
("parent") artery and a larger, rounded area called the dome. These aneurysms bulge on only one
side of the artery wall
false aneurysm (pseudoaneurysm) - ✔✔-is caused by damage to the arterial wall,
-resulting in locally contained hematoma with turbulent blood flow and a neck that typically does
not close spontaneously once past a certain size.
-a pseudoaneurysm does not contain any layer of the vessel wall
-there is blood containment by a wall developed with the products of the clotting cascade.
-Eventually, a wall forms from fibrin/platelet crosslinks that is ultimately weaker than those of a true
aneurysm.
Dissecting saccular aneurysm - ✔✔-blood is contained by the adventitia
-the part of the wall of the aorta (tunica media) splits into two layers creating a false lumen in the
wall. Entry of blood into this cavity can occlude branches of the aorta at that site.

nervous system
-renin-angiotensin-aldosterone system
-natriuretic hormone
-inflammation
-insulin resistance
insulin resistance and neurohumoral changes (hyper patho) - ✔✔contribute to systemic
vasoconstriction and increased peripheral resistance
inflammation contributes to (hyper patho) - ✔✔contributes to renal dysfunction which in
combination with the neurohumoral alterations result in renal salt, water retention and increased
blood volume.
2 causes of sustained hypertension - ✔✔-increased peripheral resistance
-increased blood volume
sustained hypertension
neurohumoral perturbations
RRA increase - ✔✔contribute to remodeling of vessels that results in hyaline sclerosis and
atherosclerosis
