A Study of Lower Limb by Venous Doppler

Abstract

INTRODUCTION: The role of lower limb venous doppler is crucial in diagnosis of Deep vein thrombosis ,varicose veins,arterio-venous malformation.DVT is the most common cause of morbidity and mortality.Tha dramatic presentation of DVT known as phlegsma dolens leads to gangrene,shock and death. DVT can endanger life of a person by producing pulmonary embolism.Varicose veins are the commonest in patients with occupational standing.The main objective is to study the spectrum of findings on color doppler in patients with clinically suspicion of lower limb venous pathology and to identify the patients who taken up for varicose surgery by locating and ruling out DVT in them MATERIAL & METHODS: A prospective study of colour duplex sonography of lower limbs was carried out for 2 years.the study was carried out 100 patients of clinically suspected lower limb venous pathology. RESULTS:100 cases were evaluated,ultrasound is non-invasive modality to diagnosis of varicose veins and deep vein thrombosis.Male(80%) predominated in our study.Swelling (34%)and varicosities(23%) were the most predominant symptoms.Prolonged hospitalization(20.51%) was the most common predisposing factor in patients diagnosed DVT and occupational standing(25.42%) were the commonest in patients with other causes of varicosities. The predominant involvement was unilateral(90%) and left lower limb(52%). In patients with DVT ,thrombus was more common confined to femoro popliteal segment than in distal segment. INTERPRETATION: Ultrasound is safe, accurate, non-invasive, easily repeatable, lack of radiation, widely available and cost-effective. So it is modality of choice for diagnosis of varicose veins and deep vein thrombosis.
