Sclerotherapy of venous malformations in oral region in children with absolute ethanol under the guide of DSA / 实用放射学杂志

ABSTRACT

Objective To evaluate the clinical effect and advantage of endovascular sclerotherapy of venous malformations in oral region using absolute ethanol under the guide of DSA.Methods The clinical data of 78 patients with venous malformation in oral region, who were indicated for ethanol sclerotherapy under DSA was retrospectively reviewed.Type classification of venous malformations was confirmed by using DSA subtraction technique during intraoperative puncture.Under general anesthesia,the malformations were punctured and then sclerosed with absolute ethanol by DSA guidance.The treatment was gone every other month,2 -6 times as a course.The length of the course of treatment depended on the type of venous malformations.Complications were also reported and analyzed. The duration of follow-up ranged from 6 to 18 months.Results Postoperative MRI showed,32 cases were cured,35 cases were significantly improved,8 cases were improved and 3 cases were invalid.There were no serious systemic complications in all cases,only 4 cases with reversible local necrosis and vesiculation.Conclusion Sclerotherapy of oral venous malformations using absolute ethanol,for its less trauma,no scar after operation,strong repeatability and exact effect,which is worthy of clinical popularization and application.
