MULTIDETECTOR CT ANGIOGRAPHY V/S COLOUR DOPPLER ULTRASONOGRAPHY IN THE DIAGNOSIS OF PERIPHERAL ARTERIAL DISEASES OF LOWER EXTREMITIES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 63
Abstract
CONTEXT Peripheral arterial disease of the lower extremity is an important cause of morbidity and affects 10 million people in India. AIMS AND OBJECTIVES The aims of this study were to assess the colour Doppler ultrasonography findings of lower limbs in patients with peripheral arterial disease by studying the spectral flow pattern and peak systolic velocity and also to assess the severity of stenosis and correlation of severity of stenosis on USG Doppler and MDCT angiography. MATERIALS AND METHODS The study included 29 patients attending surgery, Ortho OPD Government Medical College of Calicut with signs and symptoms of peripheral arterial diseases of lower limbs from January 2014 to October 2015 who underwent colour Doppler ultrasonography and MDCT angiography to know the severity of peripheral arterial diseases of lower extremities and to compare various grades of stenosis by studying the spectral flow patterns in colour Doppler ultrasonography and contrast opacification and diameter reduction in MDCT angiography. RESULTS In our study, 29 patients with intermittent claudication, numbness, and pain in the legs were selected. Majority of the patients were males and below 50 yrs. In our study, detection of totally occluded segments were better in MDCT angiography on comparing with Doppler USG. Most of the arteries showed good total agreement between Doppler and MDCT angiography. Aortoiliac group of vessels showed more than 80% total agreement between Doppler and MDCT angiography. Femoropopliteal group vessels showed more than 75% total agreement. Infrapopliteal group of vessels showed more than 50% total agreement. CONCLUSION MDCT angiography is more sensitive in detecting lesions of suprapopliteal group of vessels and also lesions with total occlusion of the lumen in comparison to Doppler ultrasonography. Imaging plays an important role in the management of the patients with peripheral arterial disease. Due to the limitations of the Doppler ultrasound, CT angiography is used prior to any vascular intervention is required in peripheral arterial diseases.
