Methods of pseudoaneurysm embolization. A pseudoaneurysm (PSA; open arrow) is noted arising from an artery (A). Flow is from left to right, and after the PSA origin the artery bifurcates into multiple arteriolar branches. The sandwich technique (B) gives both distal and proximal control of the PSA, preventing retrograde filling of the PSA from the distal branches. The PSA itself can be packed with multiple coils (C); conversely, the origin (D) or the neck (E) can be embolized. If distal control cannot be safely obtained, particles can be injected beyond the PSA origin, followed by proximal coil embolization (F).
