I71.43
Infrarenal abdominal aortic aneurysm, without rupture
Clinical Classification Guidelines
Medical Intelligence & Overview
An infrarenal abdominal aortic aneurysm (AAA) is a swelling or bulging in the lower part of the aorta, the main blood vessel that supplies blood to the abdomen, pelvis, and legs. Specifically, 'infrarenal' refers to the location of the aneurysm below the arteries that supply the kidneys. While this condition is serious, when it does not rupture, it is considered a preemptive warning sign, allowing for monitoring and planned treatment to prevent complications. Recognizing and understanding this condition helps facilitate appropriate medical management and timely intervention.
Causes & Symptoms
Clinical Causes: Aneurysm formation due to atherosclerosis (buildup of fats, cholesterol, and other substances in artery walls). Genetic predisposition or family history of aneurysms. Age-related weakening of the arterial wall, more common in older adults. High blood pressure (hypertension) increasing stress on arterial walls. Smoking, which damages blood vessels and accelerates degenerative changes. Infections or inflammatory conditions affecting blood vessel walls, though less common.
Key Symptoms: Often asymptomatic in early stages; individuals may not notice any signs. A pulsatile sensation in the abdomen, especially near the navel. Lower back pain or abdominal discomfort that may be persistent or intermittent. A feeling of fullness or a throbbing sensation in the abdomen. In some cases, a visible pulsating mass in the abdomen. Symptoms can worsen if the aneurysm enlarges or begins to compress nearby structures.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves physical examinations and imaging tests. During a physical exam, a healthcare provider may detect a pulsatile abdominal mass. Imaging techniques confirm the presence, size, and location of the aneurysm:
Treatment Protocols: Treatment strategies depend on the size and growth rate of the aneurysm. For infrarenal AAAs without rupture, management options include:
