Evaluation the result of flouroscopy-guided sclerotherapy in treating superficial venous malformation
Main Article Content
Abstract
Objective: Describe characteristics imaging of superficial venous malformation (VM) on flouroscopy and evaluate effectiveness of foam sclerotherapy.
Methods: Prospective and retroprestive cohort from November 2015 till July 2019 on 17 patients with VM treated by flouroscopy-guided sclerotherapy with 21 lesions and 46 seasons sclerotherapy. Evualating results of treatment based on improvement in symtomps ( pain- Visual Analogue Score) and imaging ( MRI- repeat MRI after last season for 6 months . There are 4 grade in improvement in imaging: excellent ( reduction in size of lesion over 90 %), good ( reduce 50 -90 %), average
( 10-50 %) and no reponse ( less 10 %). Evualating recurrence based on increasing pain score (VAS) or size in MRI. Using SPSS 20.0 to analize and process data.
Results: 17 patients (7 males and 11 females) with VM were involved in our study. Patients were a mean of 26.5± 12.9 years old (range: from 6 to 59). Evualated by digital subtraction angiography, the lesion were categorized into 4 types according to the venous drainage features. Of the 21 lesion: 3/21 had type I (14.3 %), 12/21 had type II (57.1%); 2/21 had type III (9.5 %) and 4/21 had type IV (19 %). Total seasons are 46. 8/21lesions (38.1 %) achieved excellent response, 9/21 (42.9 %)
achieved good response, 3/21 (14.3 %) achieved average response and 1 patient (4.8%) no response in magnetic resonance imaging in magnetic resonance imaging assessments. Mean VAS scores after treatment for 1 month: 1.4; 3 months: 0.9; 6 months: 1.1, min: 0, max: 5. The long- term recurrence rates with follow-up time from 1 to 2 years is: 3/4 patients had
recurrence (75 %) include of 1 patients had increasing imaging and pain score, 2 patients just had only increase imaging in MRI.
Conclusion: Flouroscopy-guided sclerotherapy is a safe and effective procedure to reduce size and pain for patient with venous
malformations that have symptoms. But the long – term recurrence rates is quite high.
