Figures
- Fig 1.
Demonstration of measurement of the PED length. Only 1 of the 6 material lines is shown.
- Fig 2.
A PED covered the ophthalmic artery initially after treatment, but the PED retracted distally and uncovered the ophthalmic artery at 6 months (patient 7 in group 2).
- Fig 3.
Minor PED retraction is shown in 2 cases in group 1. The PEDs in white are seen immediately after deployment, and the PEDs in red are from the follow-up, (left) case 2 and (right) case 1.
- Fig 4.
A change of vessel curvature is observed in 2 cases in group 2. A, Case 6 (white is for the posttreatment, and red for 6-month follow-up). B, Case 1 (white indicates posttreatment, and red shows the 6-month follow-up). C, Further PED movement in case 1 is observed between 6 (in white) and 24 (in red) months.
- Fig 5.
Acute and subacute changes of a 4 × 18 mm PED. The PED in white is immediately after deployment, yellow is the 1-month follow-up, and red is the 7-month follow-up. Left: Acute change in the first month after deployment. Right: Subacute change of the PED between the 1- and 6-month follow-ups.
- Fig 6.
A, A linear relationship between the deployment length and the length at 6-month follow-up. B, The PED elongation is independent of the initial PED oversize.
- Fig 7.
The relationship between device oversize and shortening (A) and recoil (B).
