ROLE OF COLOUR DOPPLER STUDY FOR EVALUATION OF LOWER LIMB DEEP VEIN THROMBOSIS

Abstract

Introduction- Deep vein thrombosis is a common clinical problem. It can endanger life of a person by producing pulmonary embolism and may cause venous hypertension. and chronic venous insufciency. Evaluation of patients wi Aim- th suspected deep vein thrombosis by using color Doppler ultrasonography. After obtaining clearance from Institute's ethical commit Method- tee, all the patients fullling the inclusion criteria were selected and written consent is obtained. They will be investigated with color Doppler using GE logic P9 and P5 ultrasound machine's high frequency linear transducer. The protocol begins with the patient in supine position from upper thigh till foot with longitudinal and transverse scanning to examine the veins from the common iliac veins down to calf veins. Results- In our study 50 patients with clinically suspicion of lower limb deep vein thrombosis were subjected for Doppler examination. Out of all the patients the maximum incidences of deep vein thrombosis were noted in the age group of 31-50 yrs. i.e. 48%, and minimum incidence in the age group of 11-30 yrs. i.e. 14%. The age group of 51-70 yrs. had 22% of patients and that of 71-90 yrs. of age group had 16% of patients out of total patients in the study. Out of all the patients it was found that majority of the patients were male 78% while incidence in female patients is 22%. Out of 50 suspected patients of deep vein thrombosis 60% of them were found to be positive or presence of deep vein thrombosis and 40% of them had negative or absence of deep vein thrombosis.Deep vein thrombosis was more common in right extremity i.e. 50% then left extremity i.e. 46%. Only 4% of patients had bilateral involvement. Deep vein Conclusionthrombosis of lower limbs can be detected reliably, non-invasively and rapidly by the use of colour doppler ultrasonography. Gray scale ndings together with colour doppler helps in qualitative evaluation of the venous system of lower limbs and early detection of deep vein thrombosis in clinically suspected Thus it can be concluded that keeping in mind the limitations. and the advantages offered by the colour doppler ultrasonography, it is a good, reliable, inexpensive and rapid method of investigation for deep vein thrombosis of lower limbs.
