Peripheral AVMS pre-operative embolization using plug and push technique with low-density NBCA/LIPIODOL can be used in high-flow feeding arteries at Hue Central Hospital, Vietnam: a case report

Purpose: The aim of this study was to report our experience in one casepre-operative embolization of high-flow peripheral arteriovenous malformations (AVMs) using plug and push technique with low-density NBCA/LIPIODOL. Case presentation: A patient 26 years old man hospitalized at Hue Central Hospital, Vietnam with big pulsatile mass at right femoral above the knee. Doppler ultrasound showed a mass with high systolic and diastolic velocities. Patient felt discomfort and he has a desire to resolve this condition. Angiogram showed a large and high-flow arteriovenous malformation type IV according to Yakes classification. A multidisciplinary discussion was required between surgeon and interventionist because of the high risk of in-operative hemorrhage. Patient was treated with low-density NBCA/LIPIODOL 12.5% embolic agents by transarterial approach using plug and push technique before surgical excision. Results: Technical success was achieved in this patient. Complete devascularization was obtained and surgical excision was performed at 4 days after embolization procedure. Non-target NBCA/LIPIODOL embolization was not observed. Conclusions: Embolization using plug and push technique with low-density NBCA/LIPIODOL is an promising and interesting option for management of peripheral high-flow AVMs either pre-operatively or as a single treatment.
