Tandem lesion (or tandem occlusion) is a term used in cerebrovascular imaging and intervention to refer to the simultaneous presence of high-grade stenosis or occlusion of the cervical internal carotid artery and thromboembolic occlusion of the intracranial terminal internal carotid artery or its branches, usually the middle cerebral artery 1.

SUMMARY: Approximately 15% of patients undergoing endovascular thrombectomy for anterior circulation acute ischemic stroke have a tandem lesion, defined as a severe stenosis or occlusion of the cervical internal carotid artery ipsilateral to its intracranial occlusion. Tandem lesions were defined as cases in which an extracranial internal carotid occlusive or stenotic lesion accompanied the principal (intracranial) lesion treated. No additional specifications were made about patient selection based on baseline imaging findings, and no restrictions were placed on the management of tandem lesions. The most common etiology is cervical ICA atherosclerosis, but tandem lesions can also result from cervical ICA dissection.

1999-04-01 2011-02-23 Tandem lesions were defined as a combination of a relevant extracranial internal carotid artery (ICA) pathology (ipsilateral stenosis >70% or occlusion) and concomitant intracranial large vessel occlusion. Successful reperfusion was defined as modified thrombolysis in cerebral infarction score of 2b-3. These compounds are considered tandem lesions because of concomitant damage to both sugar and base moieties of the same nucleoside. The cyclization reaction was first observed in adenosine 5′-monophosphate (AMP) upon • OH attack, giving rise to 8,5′-cyclo-AMP (4).

Tandem mass spectrometry, also known as MS/MS or MS 2, is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples.

Tandem occlusions (TOs) involving occlusion of the cervical internal carotid artery (ICA) and concomitant intracranial large-vessel occlusion (LVO) of either the intracranial ICA and/or proximal middle cerebral artery (MCA) have poor response to IV thrombolysis alone,1 and are known to be a predictor of poor outcome after thrombolysis.2 In recent years, endovascular thrombectomy 4- calcified lesions •More risk of: Non dilatable lesion Risk of dissection and perforation Conventional angiography is moderately sensitive for the detection of extensive lesion calcification but is less sensitive for detection of milder degrees of lesion calcification • The repair of tandem carotid lesions has been described using myriad methods, often involving a hybrid approach of stenting with carotid endarterectomy. Because of the worrisome stroke rates associated with this method, we have reported an innovative technique of transcarotid artery revascularization (TCAR) for tandem lesions in a patient with high-grade stenosis of the right common and 8,5‘-Cyclopurine 2‘-deoxynucleosides are among the major lesions in DNA that are formed by attack of hydroxyl radical. These compounds represent a concomitant damage to both sugar and base moieties of the same nucleoside and thus can be considered tandem lesions. Because of the presence of a covalent bond between the sugar and purine moieties, these tandem lesions are not repaired by base Imperial College London, London, United Kingdom Justin Davies, MBBS, PhD is a consultant for Volcano Corporation.

Currently, still numerous unanswered questions remain, e.g. regarding the organization of stroke networks, the value of IV tpA pretreatment. One important topic in contemporary acute stroke care is the treatment of so called tandem lesions (i.e. extracranial 2012-10-29 · INTRODUCTION. Tandem lesions are modifications of DNA in which two adjacent nucleotides on the same strand are modified. The exemplar displayed in Fig. 1a, denoted as d(G^T), has adjacent nucleotides linked by a covalent bond between C8 of guanine and the methyl carbon atom of thymine.

Infrequently, despite the finding of a severe arterial stenosis at B-mode imaging, the velocities and spectral configuration of the poststenotic segment are normal or only slightly abnormal (,,,,, Figs 1, ,,,, 2).This can occur in cases where an additional severe stenosis, downstream from the imaged lesion, causes dampening of the PSV in the vascular segment between the two Acute ischemic stroke with tandem lesions: Technical endovascular management and clinical outcomes from the ESCAPE trial October 2017 Journal of Neurointerventional Surgery 10(5):neurintsurg-2017 DNA lesions are formed continuously in each living cell as a result of environmental factors, ionisation radiation, metabolic processes, etc. Most lesions are removed from the genome by the base excision repair system (BER). The activation of the BER protein cascade starts with DNA damage recognition by glycosylases. Uracil-DNA glycosylase (UDG) is one of the most evolutionary preserved Tandem lesion (cerebrovascular) Tandem lesion (or tandem occlusion) is a term used in cerebrovascular imaging and intervention to refer to the simultaneous presence of high-grade stenosis or occlusion of the cervical internal carotid artery and thromboembolic occlusion of the intracranial terminal internal carotid artery or its branches, usually tandem lesion. Approximately 15% of patients undergoing endovascular thrombectomy (EVT) for anterior circulation acute ischemic stroke (AIS) have a tandem lesion (TL), defined as a severe stenosis or occlusion of the cervical internal carotid artery (c-ICA) ipsilateral to its intracranial occlusion.
