Endovascular Treatment of Tandem Lesions of the Carotid Arteries.

Annals of Vascular Surgery, 2014
High-grade stenoses of both common (CCA) and the internal (ICA) carotid arteries are rare and represent a therapeutic dilemma for the treating physician. The aim of this article is to present our experience with fully endovascular repair of those lesions.Between January 2011 and December 2012, 5 patients (all male, age 73.6 years) with concomitant CCA ...

Management and Treatment of Tandem Carotid Lesions

Annals of Vascular Surgery
Tandem lesions of the proximal aortic branch vessels and carotid bifurcation are uncommon. While management strategies vary, a hybrid approach of carotid endarterectomy with retrograde common carotid artery (CCA) or innominate artery (IA) stenting has become a mainstay of treatment. The purpose of this article was to provide a review of the literature,

Carotid Stenting With Antithrombotic Agents and Intracranial Thrombectomy Leads to the Highest Recanalization Rate in Patients With Acute Stroke With Tandem Lesions.

JACC: Cardiovascular Interventions, 2018
OBJECTIVES The aim of this study was to identify the optimal endovascular approach in patients with acute stroke with tandem lesions. BACKGROUND At present, there is no consensus about the ideal technical strategy for the endovascular treatment of ...

Tandem Lesions and Other Products in X-Irradiated DNA Oligomers

Radiation Research, 1998
Free radicals interact with DNA bases to produce secondary radicals. The secondary radicals are reactive species and tend to interact with neighboring bases, resulting in DNA lesions with two adjacent modified bases. In this study the DNA oligomers d(CpApTpG) and d(CpGpTpA) were exposed to free radicals generated in anoxic aqueous solution by X ...

Carotid Artery Tandem Lesions Frequency and Consequences for Endarterectomy

Rivista di Neuroradiologia, 1998
We determined the frequency of tandem carotid lesions within the carotid siphon, common carotid artery and proximal intracerebral arteries as well as incidental intracranial saccular aneurysms. We also determined the consequence of a tandem lesion on the surgeon's decision-making process when a hemodynamically significant stenosis or aneurysm was ...

Tandem lesions arising from 5-(uracilyl)methyl peroxyl radical addition to guanine: Product analysis and mechanistic studies.

Chemical Research in Toxicology, 2019
The reaction of hydroxyl radical (HO●) with thymine in DNA generates 5-(uracilyl)-methyl radicals (T●) and the corresponding methylperoxyl radical (TOO●) in the presence of O2, which in turn propagates damage by reacting with a vicinal nucleobase.

Tandem Lesions of the Internal Carotid Arteries and Their Management

1979
The significance of the combination of two or more vascular lesions (stenoses and occlusions) causing disturbances in the cerebral circulation has long been understood. Therefore, it is not surprising that, in one fifth of the patients with internal carotid occlusion a severe stenosis can be found in the contralateral internal carotid artery.

RARE INTRAMEDULLARY TANDEM LESION ON MRI DUE TO SPINAL ARTERIOVENOUS FISTULA

Neurology, 2008
Spinal dural arteriovenous fistula (SDAVF) rarely presents as multiple signal-hyperintense intramedullary lesions on T2-weighted imaging, a finding more commonly seen in multiple neoplastic diseases like lymphoma or in demyelinating, inflammatory, infectious, or multilevel degenerative diseases.

A Case of Tandem Lesions in the Extracranial Internal Carotid Artery

Archives of Surgery, 1983
The tortuous internal carotid artery is occasionally encountered during carotid endarterectomy. While much has been written about the hemodynamic problems associated with the tortuous vessel, a second atherosclerotic plaque in the kinked portion of the artery has not been reported previously, to our knowledge.

Simultaneous Endovascular Treatment of Tandem Internal Carotid Lesions

Vascular and Endovascular Surgery, 2016
The incidence of concomitant extracranial carotid artery stenosis and ipsilateral intracranial carotid aneurysm has been reported to vary between 2.8% and 5%. These complex lesions may present a challenge for treatment decision-making. This case report describes an asymptomatic male patient with severe carotid bifurcation stenosis, coupled with an ...
