Background:In stroke patients undergoing EVT, angioplasty and stenting (A&S) has been described as a bailout technique when thrombectomy fails or intracranial stenosis is suspected. Stroke, Volume 55, Issue Suppl_1 , Page AWMP88-AWMP88, February 1, 2024.

Subclavian venoplasty is commonly performed for subclavian vein stenosis in patients with long-term dialysis lines or fistulae. Such stenosis may also occur in patients with previously implanted intra-cardiac devices. Venoplasty was performed using peripheral angioplasty balloons after which the device was implanted.

Recent research has identified venous sinus stenosis as a cause of IIH, a common treatment of which is venous stenting and angioplasty. An adverse event of this procedure is in‐stent stenosis (ISS), due to either neointimal hyperplasia or hypersensitivity to an element in the stent.
