Abstract

Objective: To determine the diagnostic accuracy of handheld doppler ultrasound in detection of peripheral arterial disease taking Ankle Brachial Pressure Index (ABPI) as a gold standard.

Study Design: Cross-sectional study

Place and Duration: Study was conducted at Pakistan Institute of Medical Sciences, Islamabad during from 1st Dec 2019 to 31st May 2020.

Methods: Total 110 patients of both genders with ages 30 to 70 years clinically suspected with peripheral vascular diseases were enrolled in this study. Patients detailed demographics including age, sex, BMI, symptoms and co-morbidities were recorded after taking written consent. Handheld Doppler ultrasound examination was done to all the patients. Ankle brachial pressure index and toe pressure were performed. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of handheld Doppler ultrasound were examined. Data was analyzed by SPSS 24.0.

Results: Out of 110 patients 60 (54.55%) were males while 50 (45.45%) were females. 42 (38.18%) patients were ages <40 years and 68 (61.82%) patients had ages >40 years. 68 (61.82%) patients had peripheral vascular disease by handheld Doppler ultrasound examination and by ankle brachial pressure index 72 (65.45%) patients had peripheral vascular disease. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of handheld Doppler ultrasound were 88.89%, 90.70%, 94.12%, 82.98% and 89.57%.

Conclusion: It is concluded that handheld Doppler ultrasound is very useful tool for detection of peripheral vascular disease.
