Carotid artery stenting is commonly used to treat carotid artery stenosis. However, carotid in-stent restenosis remains a challenging problem. Herein, we report a difficult case of recurrent severe carotid in-stent restenosis with total contralateral internal carotid artery occlusion treated with repeat drug-eluting balloon inflations. The outcome after one year of follow-up showed a good result.

Background And Purpose: The quantitative intra-arterial flow dynamics following percutaneous transluminal angioplasty and stenting (PTAS) for severe intracranial artery stenosis have never been investigated. We aimed to evaluate peritherapeutic intracranial artery flow dynamics following PTAS with quantitative magnetic resonance angiography (qMRA) to predict long-term stent patency.
Design: This is a prospective, single-center study.

Background: In-stent restenosis (ISR) is a potential severe complication that occurs in patients with severe carotid artery narrowing after carotid angioplasty and stent placement. However, this phenomenon has not been fully studied in the context of interventional treatment for chronic internal carotid artery occlusion (CICAO).
Purpose: To quantify the ISR rate and identify the risk factors leading to this event.

Background: Intravascular ultrasound-determined plaque protrusion (PP) during carotid artery stenting (CAS) using conventional stents is reported in 7.6% to 12% of cases and is associated with periprocedural cerebral embolism. The Casper/Roadsaver stent (CRS) is a dual-layer micromesh stent designed to reduce the risk of PP, with a mesh cell diameter 4-fold smaller size than that of conventional stents.

Objectives: The use of homograft for vascular reconstruction is a common practice in infective setting or to prevent aneurysmal dilation over the time. The use of fresh arterial homograft is conversely rarely reported.
Methods: We report a case about the use of fresh arterial homograft as a substitute of carotid intra-stent stenosis.
