BACKGROUND Carotid artery stenting (CAS) is a reasonable alternative to carotid endarterectomy (CEA), especially in patients at high risk for surgery. Carotid artery thrombosis of the treated segment is a rare, early but potentially devastating complication of this endovascular procedure. The aim of this article is to identify and critically review cases of acute stent thrombosis reported in th...

BACKGROUND Renovascular disease is the most frequently encountered secondary cause of hypertension and is one of the few potentially reversible causes of chronic renal failure. These patients are at increased risk of having cerebrovascular events following operative management for atheromatous renal-artery stenosis. We studied the prevalence of carotid-artery disease in patients with atheromato...

This is a carotid artery stent (CAS) case report, which avoids post-stent deployment angioplasty (Post-SDA), with duplex confirmed continued stent expansion at 1, 3 and 30-day post deployment. This report confirms that self-expanding nitinol stents in the carotid artery may not require Post-SDA. We believe CAS can be performed without Post-SDA, which helps reduce the occurrence of intraoperativ...

Background: Carotid artery stenting (CAS) has recently been recommended as an alternative to carotid endarterectomy (CEA) by some clinicians. Objective: This study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in Iran for CAS with protection devices, to document our results and guide further use of CAS. Methods: From December 2...

Periprocedural neurological complications (PNCs) after carotid stenting were retrospectively analyzed to determine the risk factors with the use of various protective devices. Forty-three lesions in 40 patients were treated by carotid stenting with distal balloon protection for nearly all postdilation procedures and some predilation procedures. The following variables were statistically analyze...

A 47-year-old woman with stage IV chronic kidney disease developed a fistula between common carotid artery (CCA) and internal jugular vein (IJV) during central catheterization of the right IJV. The patient was treated with a self-expandable graft stent, which achieved successful closure of the carotid-jugular fistula. As demonstrated in our case, self-expandable graft stents could be a feasible...

A 66-year-old man suffering from neurologic symptoms caused by acute embolic total occlusion of the left middle cerebral artery was treated successfully with balloon angioplasty, and an ipsilateral carotid stenosis subsequently was dilated with stenting. The patient's clinical outcome 30 days later was favorable. This therapeutic option may prove to be a useful means of treating a patient with ...

Fibromuscular dysplasia typically occurs in young women and most commonly presents with hypertension, transient ischemic attack, stroke, or an asymptomatic cervical bruit. The disease is nonatherosclerotic and noninflammatory and most often affects the renal and carotid arteries, although almost any artery can be involved. On angiography, affected blood vessels characteristically resemble a str...

Background Multilevel significant atherosclerotic disease involving the carotid bifurcation and the proximal ipsilateral common carotid or brachiocephalic arteries presents an uncommon and difficult management problem. Axial (aortocarotid bypass) or extra-anatomic procedures (subclavian–carotid bypass, carotid–carotid bypass, carotid–subclavian transposition) and variations in the performance o...

We report here on a rare case of carotid artery angioplasty and stenting in a patient with spontaneous recanalization after complete occlusion of the proximal internal carotid artery (ICA). The patient initially showed severe stenosis at the left proximal ICA on MR angiography (MRA). Digital subtraction angiography (DSA) performed three days after MRA showed complete occlusion of the proximal I...
