Study of Common Carotid Arteries in diabetic Patients by Using Ultrasound

Abstract

The aim of this study is to evaluate the accuracy of Ultrasound in detecting the impact of diabetes mulletus on carotid arteries. This study was done among 60 Sudanese patients. The data were collected during the period April 2012 to April 2013 in clinic of College radiological science and other clinics in Khartoum hospitals, all patients were affected with D.M. Divided into two groups: Group (1) 50 patients, the study depends on practical scanning of carotid arteries of all patients and based on different parameter which is intima – media. Thickness (IMT), caliber and presence of plaque of carotid arteries and correlating between these parameter using B-mode Ultrasound In this study the IMT ranges from 0.09 cm to 0.20 cm (mean 0.15± cm) for the Rt CCA and from 0.08 cm to 0.20 cm (mean 0.13± cm) for the Lt CCA. The caliper of Rt CCA ranges from 0.57 cm to 0.89 cm (mean 0.69± cm) and the left CCA ranges from 0.47 cm to 0.90 cm (mean 0.66± cm). Group (2) were contained ten patients scanned by Doppler ultrasound to find the correlation between intima media thickness for right and left and RI and PI, with both correspond to the impedance of the flow in the vessels were calculated by the ultrasound machine. A good correlation was noted between the intima media thickness and Resistive Index and intima media thickness and the pulsatility index, the intima media thickness is directly proportional to the RI and PI in both right and left common carotid artery. For the right common carotid artery the RI ranges from 0.5 to 0.8 and the PI ranges from 1.75 to 2.10, while for the left common carotid artery the RI ranges from 0.5 to 0.91 and the PI ranges from 1.74 to 2.20 Finally the study showed atherosclerosis plaque in CCAs in some of patient.
