Study Notes
Understanding Aneurysms
Definition
An aneurysm is a bulging, weakened area in the wall of a blood vessel due to an abnormal widening or ballooning greater than 50% of the vessel's normal diameter. They can occur in various locations throughout the body, including arteries in the brain (cerebral aneurysms), the aorta (the largest artery in the body), neck, intestines, kidney, spleen, and vessels in the legs. Aneurysms can be characterized by their location, shape, and cause.
Causes
The exact cause of aneurysm formation is not fully known. However, factors such as age, family history, genetic conditions, infection, head trauma, high blood pressure, elevated fats and cholesterol levels, smoking, and congenital disorders are believed to contribute to their development.
Symptoms
Aneurysms may be asymptomatic or symptomatic, depending on their size and location. Symptoms associated with different types of aneurysms include sudden severe headache, nausea, vomiting, visual disturbances for cerebral aneurysms; constant pain in abdomen, chest, lower back, or groin area for abdominal aortic aneurysms; and shortness of breath, chest pain, or irregular heartbeat for ventricular aneurysms.
Diagnosis and Treatment
Because aneurysms often have no symptoms until rupture occurs, they must be detected through medical imaging techniques like ultrasound, echocardiography, radiological imaging, MRI, CT scanning, or angiography. Treatment usually involves surgical intervention to prevent rupture, which can lead to life-threatening hemorrhage and death.
