Abdominal Aortic Aneurysm (AAA) Rupture Risk Index: Explanation and Clinical Context AAA Rupture Risk Index is a tool designed to estimate the probability of rupture in patients with abdominal aortic aneurysm. It combines key risk factors including maximum aneurysm diameter, annual growth rate, and aneurysm morphology (fusiform or saccular). Diameter remains the strongest predictor, with risk increasing significantly
Ankle Brachial Index For PAD Risk. Clinical Explanation and Context The Ankle Brachial Index is a simple and validated noninvasive test used to detect the presence and severity of peripheral artery disease. It is calculated by dividing the systolic blood pressure at the ankle by the highest systolic blood pressure measured in both arms. ABI provides an objective assessment of lower extremity perfusion and correlates
Aortic Aneurysm Expansion Index (AAEI): Explanation and Clinical Context The Aortic Aneurysm Expansion Index (AAEI) quantifies the annual relative increase in aortic diameter, expressed as a percentage per year. It is calculated using the formula: (Follow-up Diameter - Baseline Diameter) / (Baseline Diameter × Time Interval) × 100%. AAEI helps clinicians identify patients at risk of rapid aneurysm growth and potentia
