Role of Colour Flow Duplex Sonography in Evaluation of Chronic Venous Insufficiency in Lower Limbs
Journal Title: International Journal of Contemporary Medicine surgery and Radiology - Year 2017, Vol 2, Issue 3
Abstract
Introduction: DVT of the lower extremity is one of the most common cause of pulmonary embolism which in turn is responsible for majority of the deaths. Study aimed to evaluate the spectrum of findings on colour duplex ultrasound in patients who present with clinical symptoms and signs of chronic venous insufficiency. To identify patients who can be taken up for varicose venous surgery without any risk of pulmonary embolism by ruling out deep vein thrombosis. Materials and methods: it is prospective study done in 50 cases who are with all clinically suspected cases of venous disease of the lower limb, referred to the department of radiodiagnosis were evaluated. All patients underwent a detailed colour duplex ultrasound of the lower limb venous system. Results: most common age group was 41-50 yrs (12 patients,24%)male preponderance was observed. (41 patients, 82%), Left (23 patients, 46%) lower being more affected than right (16 patients, 32%) or bilateral (11 patients, 22%). Among the 50 patients examined, 43 (86%) of than had chronic venous insufficiency, 4(8%) had cellulitis and 3(6%) had baker's cyst. Of the patients with chronic venous insufficiency, 7(16.3%) patients had acute DVT. the remaining 36(83.7%) patients had varicose veins. In 46 limbs with varicose veins, 27(58.7%) cases had GSWV varicosities, 1(2.1%) had SSV varicosities and 18(39.2%) had involvement of both GSV and SSV. Perforator incompetence (58.7) was the most cause for varicosities below knee medial mid 1/3 perforators (69.5%) were found to be the most common incompetent perforators. All the 7 patients with deep vein thrombosis showed involvement of the proximal segment veins. Among the 36 patients varicose veins, 20 of them underwent surgery after preoperative mapping of the venous system. 19(95%) of the patients were in agreement with the surgical finding. Conclusion: Colour flow duplex sonography is an accurate investigation in demon striating the various spectrum of finding in a patients with CVI, and also has a high percentage correlation with operative finding.
