Transarterial Arteriovenous Malformation (AVM) Embolization. A. Fluoroscopic imaging of the left upper extremity with visualization of an AVM off the anterior circumflex humeral artery cannulated transarterially from the radial artery. B. Post embolization, improved flow can be seen to the anterior circumflex humeral artery and complete cessation of flow to the AVM.

FIG1
Two regions, one off the anterior circumflex humeral artery (Figure 1) and one aberrant malformation off the axillary artery (Figure 2), were subselectively cannulated to decrease flow rates and then embolized with Terumo HydroPearl embospheres (Terumo, Somerset, NJ, USA).
Transarterial Arteriovenous Malformation (AVM) Embolization. A. Fluoroscopic imaging of the left upper extremity with visualization of an AVM off an aberrant malformation off the axillary artery cannulated transarterially from the radial artery. B. Post embolization, trace improvement was seen with improved blushing but no cessation of flow to the identifiable vessels.

Supraclavicular Transvenous Arteriovenous Malformation (AVM) Embolization . A. Fluoroscopic imaging of the AVM off the subclavian vein proximal to the bifurcation of the cephalic vein transvenously cannulated. B. Fluoroscopic imaging of the feeding tributaries feeding the venous supply. C-D. Post embolization, patent flow of the feeding vasculature with improved flow from the cephalic tributaries. Overall improvement was seen with improved blushing but no cessation of flow to the identifiable vessels.

FIG3
A transvenous direct cannulation approach was performed using a 4 French micropuncture catheter under real-time ultrasound guidance near the clavicle (Figure 3).
Posterior Transmalformation Arteriovenous Malformation (AVM) Embolization . A. Fluoroscopic imaging of the AVM. B. Post embolization, patent flow of the feeding vessel with improved blushing and cessation of flow to the AVM.

FIG4
Next, the posterior nidus was identified and a transmalformation direct cannulation approach was performed near the lateral border of the scapula (Figure 4).
