Role of Venous Wall Thickening Detected by B Mode Ultrasonography for Diagnosis of Deep Vein Thrombosis

Abstract

Objective: evaluate the role of B mode ultrasonography for early detection of deep venous thrombosis after hip fracture surgery when venous wall thickening detected preoperatively.Study Design: Prospective Experimental Trial.Place and duration: Study was conducted in the department of Gynaecology and Obstetrics Nishter Hospital Multan and Ganga Ram Hospital ,Lahore from March 2017 to March 2018.Methodology: Study was started after ethical approval from ethical board of hospital and informed consent was obtained from patients. One hundred and ten patients were included in this study, both genders. Main outcome variables were duration of surgery, previous history of DVT, Varicose vein, venous wall thickening and deep venous thrombosis. SPPS version 24 was used for data analysis.Results: There were 11.8% patient’s venous wall thickening and 88.2% patients no venous wall thickening. DVT, proximal thrombosis and DVT associated with pulmonary embolism for venous wall thickening was observed as 76.9%, 53.8% and 38.5%, respectively. DVT, proximal thrombosis and DVT associated with pulmonary embolism for no venous wall thickening was observed as 45.4%, 10.3% and 8.2%, respectively. The difference was statistically significant.Conclusion: Deep venous thrombosis is a common risk after hip fracture surgeries, ultrasonography of venous wall is reliable diagnostic criteria, and repeated examinations should be performed when venous wall thickening is detected.
