Case Study example - Berry Aneurysms
Pages 8 (2008 words)
Arteries have thickened walls that withstand the pressure of blood pumped from the heart to the body to supply body cells with oxygen and other nutrients. There are cases when the artery walls are damaged because of trauma, genetically inherited conditions or even medical problems…
Extract of sample
An aneurysm usually balloons and may rupture as the forces increase, which would lead to rupturing of the arterial wall and interior bleeding, a situation that is usually fatal and leads to death.
Consequently, berry aneurysms results from rupture of arterial walls in the brain with fatal consequences that may cause brain death. The condition is usually caused by defects in the tunica media muscles and lack of enough support from the brain parenchyma, which creates unprecedented stress to the arterial walls causing rupture (Liebeskind, 2013). Therefore, cerebral aneurysm occur incases were the strength of the internal elastic membrane of the adventitia and the tunica media are compromised mainly resulting from abnormal arterial structure at arterial bifurcations, which results in rupture of the vessels at these sections due to blood pressure (Liebeskind, 2013).
Causes of Berry Aneurysms
Various conditions may lead to berry aneurysms, which include the following: Arterial malformations, aorta coarctation, inherited polycystic kidney diseases and other vascular problems. Others include sickle cell anemia, fungal infections, Marfan syndrome, hypertension among others (Liebeskind, 2013). However, not much is known about the actual causes of the aneurysms and the formation processes leading to ballooning and rupture, but smoking that leads to vascular changes and hypertension are major some of the major predisposing factors (Jonathan et al., 2006). The main characteristic of aneurysms is reduction in the tunica media leading to arterial structural defects. ...
