Abstract
Aim To assess the role of duplex ultrasonography (DUS) in peripheral arterial disease and comparison with multidetector computed tomography angiography (MDCTA). To compare the accuracy, sensitivity and specificity of duplex ultrasonography (DUS) and multidetector computed tomography angiography (MDCTA) to diagnose peripheral arterial disease (PAD).Materials and Methods:Study Site: Department of Radiodiagnosis and modern imaging, S.P. Medical College and Associated group of PBM hospitals, Bikaner, Rajasthan.Study Population: Patients of all ages and gender giving clinical history consistent with that of peripheral arterial disease.Study Design: This is a longitudinal prospective type of observational study.Sample Size: All the patients coming to the hospital with peripheral arterial disease during the period of study were considered, with 40 being the approximate sample size. Duration of Study: One year (from November 2020 to November 2021)Patient SelectionInclusion Criteria Patients of all ages and gender giving clinical history consistent with that of peripheral arterial disease.Exclusion CriteriaPatients who Are allergic to contrast Are pregnant Have acute/chronic renal failure Refuse the protocol and do not give consent Have undergone any vascular surgery (vascular graft or have undergone amputation) Have arterial segments where it was not possible to perform a satisfactory ultrasound examination due to technical reasons (extensive arterial calcification, intestinal flatulence)Results: In our study, 73.5% of patients were in the group of 40 years and above with the mean age of presentation being 49.9 years. The median age of presentation was 52 years. Among all the patients with clinical suspicion of PAD, 31 were males while 9 were females with male to female ratio being 3.4:1. In our study, out of 40 patients with clinical suspicion of PAD, 37 patients had lower limb complaints while 3 patients had upper limb complaints and they had unilateral limb involvement. Majority of patients had complaints of intermittent claudication i.e. 25 out of 40 cases (62.5%), followed by rest pain (22.5%), skin discoloration (7.5%), gangrene (5%) and numbness (2.5%). Out of 25 patients, true claudication was seen in 22 patients as remaining 3 cases were found to have normal Doppler USG as well as CT angiography study (i.e. grade 0 stenosis).
