Objective To explore the application of ROADMAP function in endovascular sclerotherapy of venous malformations guided by digital subtraction angiography (DSA). Methods From May 2019 to July 2020, 11 patients underwent endovascular sclerotherapy of venous malformations guided by DSA. The ROADMAP function was used to monitor the administration of sclerosant in real time during the operation. Postoperative follow-up and efficacy evaluation were performed. Results Eleven patients received sclerotherapy of 25 times for 13 lesions, with an average of (2.1±0.9) times. The average treatment period was (18.5±3.4) min, and the average use period of the ROADMAP function was (52.5±10.3) s. All patients were followed up for 24 months. Seven cases had complete response, 2 cases had significant response and 2 cases had partial response. No recurrence or progression was found. No serious complications such as bleeding, ulceration, infection or dysfunction occurred in all patients. Conclusion The ROADMAP function can improve the safety of treatment, grasp the structure of lesion, make the drug dose more accurate and does not significantly increase the operative duration. It should be considerable for clinical application. [ABSTRACT FROM AUTHOR]

Objective: To compare the clinical efficacy of Digital subtraction angiography (DSA) in the treatment of varicose veins of lower extremities with polyvinyl alcohol foam sclerotherapy. Methods: 120 patients with varicose veins of lower limbs in our hospital from October 2015 to October 2020 were selected and randomly divided into observation group and control group, with 60 cases in each group. Patients in the control group were treated with DSA-guided sclerotherapy, and patients in the observation group were treated with ultrasound-guided sclerotherapy. The treatment effect, MCS, PCs and VCSs scores, treatment cost and hospitalization time of the two groups were compared And operation time, adverse reactions. Results: The total effective rate of treatment in the observation group was96.67 %, which was higher than the total effective rate of 86.67 % in the control group. There was a statistical difference between the groups (P<0.05). There was no significant difference in the scores of MCS, PCs and VCSs between the two groups before treatment (P>0.05). After treatment, the MCS score of the observation group was higher than that of the control group, and the VCSs score was lower than that of the control group. The hospitalization time and operation time of the observation group were higher than those of the control group, and the difference was statistically significant (P<0.05). The total incidence of adverse reactions in the observation group was 5.00 %,lower than 20.00 % in the control group, and the difference was statistically significant (P<0.05). The difference was statistically significant (P<0.05). Conclusion: Ultrasound-guided treatment of varicose veins of the lower extremities has a significant effect, which can improve the mental health, physical health and clinical severity of venous diseases of patients with varicose veins, and promote the patient’s speedy recovery.
