The Effects of Multi-Slice Helical Computed Tomography and Phlebography on Edema Regression Nursing of Lower Limbs Varicosis

Abstract

Objective: To explore the effects of multi-slice helical computed tomography (MSCT) and phlebography on edema regression nursing of lower limbs varicosis, and to analyze the values of MSCT and phlebography on the diagnosis and treatment of lower limb varicosis. Methods: A total of 193 patients with lower limb varicosis treated in the Vascular Surgery Department were included as the research objects. According to different examination methods, the included patients were divided into the MSCT group, and the MSCT combined with the phlebography group, Then, patients in both groups received joint treatment of high ligation and varicectomy. The Gabor filtering-based algorithm and the Mean-Variance Efficient Frontier (MVEF) algorithm were used to smoothen the obtained images. Also, the operation rates and contradiction compositions of patients in both groups were analyzed. Patients who received surgical treatment were followed up for three months to one year; whether the deep vein thrombosis (DVT) occurred in them were observed, as well as the edema regression. Results: As for gender, grading, disease history, duration of disease, and onset age of both groups, no statistical significance was found (P > 0.05). Compared to group A, the positive detection rate of postoperative DVT was lower in group B, so did the operation rate. In group A, 32 cases of edema regressed significantly, and the disease condition was relieved. In group B, 35 cases of edema were regressed. Conclusion: Compared with MSCT, phlebography had a higher screening rate for indications of lower limb varicosis, which could effectively reduce the probability of DVT after operations and relieve the symptoms of edema in patients. In addition, although the sensitivity of MSCT was relatively low, it could be used for the primary screening diagnosis of lower limb varicosis.
