Artery Intervention
INDICATIONS AND PIVOTAL TRIALS Natural History of Renal Artery Stenosis The prevalence of renal artery stenosis (RAS) in patients with hypertension (HTN) has been estimated at 1% to 5%; however,…
Technologies: Atherectomy and Laser
The first percutaneous vascular intervention was performed in the superficial femoral artery (SFA) by Charles Dotter in 1964 using a series of relatively crude dilatation devices. Despite the long-term…
Intervention
The advancing field of percutaneous endovascular therapy has led to a significant increase in options available for the treatment of patients with symptomatic peripheral vascular disease. Previous reticence in applying…
Evaluation of Peripheral Arterial Disease
Lower extremity peripheral arterial disease (PAD) affects 8 million people in the United States, with a prevalence of 29% (1), and is part of a spectrum of atherosclerotic disease that…
Vertebral Artery Disease
Compared with anterior cerebral circulation ischemia, our knowledge regarding ischemia of the posterior cerebral circulation is more rudimentary. With improved technology that allows imaging of the brain and vascular lesions…
Ischemic Stroke
Intracranial atherosclerosis is a major cause of stroke and accounts for 8% to 10% of ischemic stroke in mixed patient populations (1–4). The vessels involved are mainly those of the…
Management of Visceral Artery Aneurysms
VISCERAL ANEURYSMS AND PSEUDO ANEURYSMS Visceral artery aneurysms and pseudoaneurysms are defined as localized arterial dilatations ≥1.5 times the expected diameter of the normal artery. These aneurysms include dilations found…
Angioplasty and Stenting
Intracranial atherosclerosis is a major cause of stroke and accounts for 8% to 10% of ischemic stroke in mixed patient populations (1–4). The vessels involved are mainly those of the…
Artery Stenting: The Data
Carotid artery stenting (CAS) was recently accepted as an alternative minimally invasive revascularization approach to carotid endarterectomy (CEA) for the treatment of high-risk patients with significant extracranial carotid artery stenosis…
