Successful Embolization of Complex Chest Wall AVM Using Liquid Embolic Agent (Onyx) through Combined Trans-femoral and Trans-radial Approaches

Case Presentation: Arteriovenous malformations (AVMs) are abnormal connections between the arteries and veins in the body. While most cases of AVMs in the chest wall are caused by acquired factors like trauma or iatrogenic, they can also be caused by congenital conditions such as neurofibromatosis type 1. Congenital arteriovenous malformations (AVM) are commonly observed in the lower limbs, while their occurrence in the thoracic wall is exceptionally uncommon. In cases where these malformations are of significant size, there exists a potential danger of hemorrhaging. This poses an additional challenge when devising a surgical intervention plan, sometimes necessitating preoperative embolization. Preoperative embolization techniques usually are challenging and might require multiple accesses and it's difficult to choose which is the best embolization agent. Here we describe a challenging case of chest-wall arteriovenous malformation (AVM) in a young male patient which was effectively treated using a liquid embolic agent (onyx) using both trans-femoral and trans-radial approach.
