Percutaneous and Open Retrograde Endovascular Stenting of Symptomatic High-Grade Innominate Artery Stenosis: Technique and Follow-Up

Abstract

BACKGROUND AND PURPOSE:Angioplasty and stenting of the IA have been reported with high technical and clinical success rates, low complication rates and good mid-term patency rates. Different antegrade or retrograde endovascular catheter-based approaches and combinations with surgical exposure of the CCA are used. The purpose of this study was to determine safety, efficacy and mid-term clinical and radiological outcome of the stent-assisted treatment of atherosclerotic stenotic disease of the IA with special focus on the different technical approaches.

A Case of Critical Calcified Innominate Artery Stenosis Successfully Treated With the Shockwave Lithoplasty

“…It is well recognized that percutaneous transluminal angioplasty of innominate artery is very challenging due to its large diameter, short length, and the proximity to the origin of the right common carotid artery (CCA). 7 In our case, the presence of a calcified plaque added another important difficulty to the percutaneous intervention. Given the impossibility to overcome this lesion with the common endovascular devices, we decided to employ Shockwave Lithoplasty.…”

Percutaneous antegrade and retrograde endovascular approach to symptomatic high-grade subclavian artery stenosis: Technique and follow-up

“…Percutaneous approach to subclavian arterial stenosis is often used with stenting as first line therapy in symptomatic patients. [36]…”

“…Angioplasty and stent placement in symptomatic subclavian artery stenosis have evolved as effective and safe treatment techniques since the 1990s. [1234] Standard open surgical procedures are now mostly reserved for extensive multivessel involvement or after failed endovascular procedures. [5] Indications for treatment include clinical symptoms ranging from upper limb ischemia and subclavian steal syndrome to vertebra basilar insufficiency.…”

“…Endovascular stent-placement interventions have been reported with high technical and clinical success rates, low complication rates, and good midterm patency rates. [345] However, potential embolic complications during balloon inflation and stent deployment to vertebral artery as well as restenosis remain an important concern. The purpose of this study was to determine the safety, efficacy, and midterm clinical and radiologic outcome of the endovascular treatment, with special focus on the different technical approaches.…”
