What Can I Expect from My Procedure?
Most of the time lesion is very large & absolute ethanol is very powerful embolic agent so to prevent complication from large dose of absolute ethanol from single sitting, it requires multiple sittings.
What are the Risks?
This procedure is done under general anesthesia so risk associated with general anesthesia will be there. Following the procedure, patients usually exhibit focal swelling in the area of malformation treated. Most patients will resolve the majority of the swelling by 2 weeks. In those patients with lower extremity and foot malformations, swelling may last longer because the leg and foot are not only dependent but weight bearing structures as well. In treating vascular malformations of the extremity, deep-vein thrombosis (DVT) is a potential complication. If the malformation has transdermal involvement (involving the layers of the skin) it is not uncommon for skin injury to occur with ultimate healing by scar formation. In the event of skin breakdown, there is risk of infection which may be treated with antibiotics. Peripheral nerve damage is another possible complication due to swelling in the treated compartments. This is usually temporary and improves once swelling has subsided. However, in very rare cases (less than 1%) it can be permanent. Complications from ethanol embolization are generally minimal and this procedure is tolerated well.
