Evaluation Of Normal Diameter Of Infra-Renal Aorta In A Pakistani Population Using Contrast-Enhanced Computed...

Area of Science:

• Vascular Surgery
• Radiology
• Public Health

Background:

• The abdominal aortic size in the Pakistani population is generally smaller than in Western populations.
• No prior studies have established normal infrarenal abdominal aortic dimensions for the local Pakistani population.
• Accurate aortic diameter measurements are crucial for identifying aneurysms.

Purpose of the Study:

• To determine the normal diameter of the infrarenal abdominal aorta in the Pakistani population.
• To investigate variations in aortic diameter based on age, gender, weight, height, body mass index (BMI), and body surface area (BSA).

Main Methods:

• A cross-sectional observational study involving 250 patients undergoing contrast-enhanced CT scans of the abdomen.
• Measurement of the anteroposterior and transverse diameters of the infrarenal abdominal aorta.
• Statistical analysis using SPSS v.23, including Pearson correlation to assess relationships between aortic dimensions and anthropometric factors.

Main Results:

• The mean anteroposterior diameter was 16.13±2.32 mm, and the mean transverse diameter was 15.96±2.34 mm.
• Aortic diameter was significantly smaller in females compared to males.
• A statistically significant positive correlation was observed between increasing age and aortic diameter (p<0.001).

Conclusions:

• Findings provide essential reference values for the Pakistani population, aiding clinicians in diagnosing abdominal aortic aneurysms.
• The study highlights demographic variations in aortic size, particularly gender and age-related differences.
• Results support the need for tailored intervention protocols considering local population characteristics.
