Introduction While cerebrovascular atherosclerotic disease is the most common pathology encountered by vascular surgeons, there are several other distinct entities that can result in cerebral ischemia, bleeding and death. This chapter discusses the rare clinical presentations and treatments for carotid…
Introduction The carotid body tumor (CBT), first described in 1743 by Von Haller, is the only known pathologic condition of the carotid body. The tumor is extremely rare. In 1971, only about 500 cases had been reported in the literature;…
Introduction Extracranial carotid artery aneurysms (ECAA) are rare in comparison with atherosclerotic occlusive disease in the same location. ECAA can occur as a result of atherosclerosis, trauma, dissection, local infection, or after carotid endarterectomy (CEA). These aneurysms occur less frequently…
Introduction Carotid artery dissection (CAD) usually occurs secondary to a tear in the intimal layer disrupting the integrity of the arterial wall, which allows blood to leak and accumulate between arterial wall layers. CAD can occur at any age, but…

Introduction The concept of endovascular therapy for treatment of carotid artery stenosis was first proposed in 1977 by Mathias, who reported successful results of carotid artery angioplasty using peripheral arterial angioplasty technology. , Balloon-expandable stents for the treatment of cerebrovascular…
First performed in the 1950s, carotid endarterectomy (CEA) experienced remarkable growth in the 1970s and 1980s after several studies demonstrated that carotid stenosis was an important risk factor for disabling stroke and death, and a randomized multicenter trial published in…
Carotid Disease And Stroke The management of symptomatic and asymptomatic carotid disease has been the subject of six randomized controlled trials (RCTs) comparing carotid endarterectomy (CEA) with optimal medical therapy (OMT), whereas 20 RCTs have compared CEA with either carotid…
Diagnostic Tools Duplex Ultrasound Duplex ultrasound (DU) refers to two modes of ultrasound, namely B mode that obtains gray-scale imaging, and Doppler that evaluates the velocity and direction of blood flow in the vessel. DU determines the degree of carotid…
Introduction A decline in cognitive function from ischemic, hypoperfused or hemorrhagic brain lesions has been termed “vascular cognitive impairment” (VCI). While memory dysfunction is an important correlate of classic dementias, VCI is generally associated with dysfunction in executive function and…
