Having reviewed 300 carotid angioplasties for symptomatic >70% ICA stenosis, we found three patients (1%) with intraluminal thrombus. Conservative treatment with anticoagulants and double antiplatelet coverage can result in lysis of the thrombus without severe risks. Percutaneous transluminal angioplasty and stenting, preferably with distal protection, can be an excellent alternative to carotid endarterectomy.

Percutaneous transluminal angioplasty (PTA) is a well-established treatment for patients with subclavian stenosis, but its efficacy in total subclavian or innominate occlusions is so far not well established. Since 1995, we have carried out 9 PTA revascularizations in 9 patients with total symptomatic atherosclerotic occlusion of supraaortic vessels. The technical success rate was 100%, without any major (death or stroke) or minor complications. In the follow-up period (mean 37.4 months), 1 patient had a symptomatic left internal carotid artery occlusion and an asymptomatic occlusion of the treated subclavian artery. In expert hands, stenting-PTA should be considered as the primary therapeutic option.

Endovascular transarterial treatment with a self-expanding covered stent was used to close the fistula successfully with preservation of the parent artery.
