Innovative Approach for Successful Cure of a Digital AVM With Glue and Venous Tourniquet.

Abstract

BackgroundArteriovenous malformations (AVM) of the digits are rare and carry a poor prognosis after surgical resection and embolisation and usually end up in digital amputation. We present a unique case of a digit AVM treated using glue by dual approach, ie, transarterial and percutaneous route with a proximal tourniquet, where we could completely salvage the digit involved with a significant reduction in symptoms.Case PresentationWe report a case of a 20-year-old male who presented with swelling of the right ring finger for the past 10 years, with new onset pain and increased swelling size in the last 2 years. A diagnosis of arteriovenous malformation was made on ultrasound and magnetic resonance angiography (MRA) imaging. To salvage the digit, meticulous planning and multidisciplinary discussion for embolization using super-selective angiography were done. Successful embolisation of nidus with feeder from both metacarpal arteries of the ring finger was done using glue by transarterial and percutaneous route with a proximal tourniquet. Near total obliteration of nidus was achieved with no early opacification of the draining vein. Short-term follow-up of 4 months revealed a significant reduction of swelling and pain with no major complication.ConclusionsGlue embolization with a dual approach and proximal tourniquet is safe and effective in digital AVM for symptom reduction with no major complication.
