A patient has been diagnosed with a 4cm abdominal aortic aneurysm. Which of the following conditions would indicate surgical intervention may be necessary?
Patient is male and is 28 years old
Patient has Marfan's syndrome
Patient has hypertension and is prescribed a beta-adrenergic blocking agent
Patient expresses concern about dying
The Correct Answer is B
A. A 4 cm aneurysm in a young patient, especially one as young as 28 years old, would typically be monitored more closely rather than immediately undergoing surgery. Surgical intervention is more commonly considered for larger aneurysms or in cases where there are other risk factors or symptoms present.
B. Marfan's syndrome is a genetic disorder that affects connective tissue and is associated with a higher risk of developing aortic aneurysms, including abdominal aortic aneurysms. Patients with Marfan's syndrome are at a greater risk of aneurysm growth and rupture due to the weakened connective tissue.
C. Hypertension is a significant risk factor for the growth and rupture of an AAA. While managing hypertension with beta-blockers is important in controlling the risk, the presence of hypertension alone does not necessarily indicate that surgical intervention is immediately necessary
D. While patient concerns and anxiety about their condition are valid and important, expressing concern about dying does not directly determine the need for surgical intervention. Surgical decisions are based on objective clinical criteria, such as the size of the aneurysm, growth rate, symptoms, and overall health of the patient.
