Patients with extrinsic stenosis only
| Patient No | LP OP cm H2O | Initial pressure gradient mm Hg | Pressure gradient after failure mm Hg | Number of restenting procedures (months after last stent placement) | Level of top of stents | Indication for restenting | Last pressure gradient (months after last stenting) mm Hg | Months free from papilledema after last stent placement |
|---|---|---|---|---|---|---|---|---|
| 16 | 55 | 23 | 28 | 2 (17.7, 16) | Junction post/mid-SSS | Recurrent papilledema before each restenting | 5 (50) | 50 |

| 21 | Elevated | 20 | 25 | 2 (17.3, 1.3) | Mid-SSS | Rapidly worsening VF constriction; referred urgently for new stent without examination for papilledema | 3.5 (25.7) | 25.7 |
| 26 | 43 | 18 | 14 | 1 (5.7) | Mid-SSS | No recurrent papilledema; neuro-ophthalmologist recommended repeat stenting because of severity of prior papilledema and permanent visual deterioration in one eye | 3 (23.5) | 24.7 |
