Tandem occlusion is defined by an acute ischemic stroke (AIS) with concomitant steno-occlusive disease of the extra cranial carotid artery and concerned about 10% of AIS patients. Whereas endovascular treatment has shown its efficiency in AIS by large vessel occlusion (LVO), to date, there is no consensus on the endovascular management of the extra cranial carotid artery in tandem occlusion.

2-Deoxyribonolactone is an abasic lesion whose replication in Escherichia coli does not adhere to the A-rule (31, 32). Lesion Length • Lesion length > 20 mm called diffuse. Methods used to measure lesion length are “shoulder-to-shoulder” method vessel narrowed >20%, or Lesion length with >50% narrowing Distance between proximal and distal “angiographically” normal segements “Tandem Lesion” If the gap between lesions < 3 * reference diameter of vessel called Tandem lesion and considered one lesion 2018-09-21 · Tandem occlusion was defined as extracranial ICA lesion (complete occlusion or severe stenosis of ³90% by NASCET criteria, and a proximal intracranial occlusion (distal ICA, and/or M1, and/or M2). 2021-02-04 · The diagnostic accuracy of the QFR in the subgroup with tandem lesions was 93.97% (95% CI 91.29 to 96.02%), which was lower than that of the nontandem lesion group (96.59% 【目的】頭蓋内外主幹動脈病変を有する脳虚血症例（tandem lesions）に対する血管内治療は治療 機器の選択等に工夫を要するため自験例を報告する．【症例】66歳 男性．意識障害（JCS 100） と左片麻痺（MMT 0/5）で発症．National Institute of Health Stroke Scale（NIHSS）31． Tandem lesion was risk factor for endovascular treatment in acute basilar artery occlusion: a single center retrospective observational study Xuan SUN, Feng GAO, Xu TONG, Yi⁃ming DENG, Ning MA, Da⁃peng MO, Li⁃gang SONG, Lian LIU, Xiao⁃chuan HUO, Xiao⁃tong XU, Zhong⁃rong MIAO During the last years, endovascular treatment has evolved as the standard of care for acute ischemic stroke with large vessel occlusions. Currently, still numerous unanswered questions remain, e.g. regarding the organization of stroke networks, the value of IV tpA pretreatment.

The aim of this study was to test the hypothesis that the fractional flow reserve (FFR) gradient across an individual stenosis (ΔFFR) during pressure-wire pullback is a surrogate of the relative functional severity of each stenosis in coronary tandem lesions.
• Coronary tandem lesion was defined as two separateCoronary tandem lesion was defined as two separate stenoses with ≥50% diameter stenosis by visual estimation within one epicardial coronary artery,
1'2 One of the problems in the two previous. It is not clear either isolated 60% discrete or 60% tandem lesions can result more severe stenosis.
The most common etiology is cervical ICA atherosclerosis, but tandem lesions can also result from cervical ICA dissection. Perhaps the biggest conundrum in the management of tandem lesions is whether or not to stent the cervical ICA in the acute setting.
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. BackgroundTo evaluate the acute and long-term results of 'tandem lesion' coronary angioplasty in the left anterior descending artery, and to identify the determinants of restenosis. MethodsA retrospective analysis of clinical, angiographic, and procedure-related variables was caarried out on a consecutive series of 102 patients (mean age 54 years, range 34–71 years; 77% men) who had Tandem lesions of the internal carotid artery and proximal arch branch vessels are uncommon. This leaves uncertainty about the safest treatment approach, with mixed results reported in the literature.

These compounds represent a concomitant damage to both sugar and base moieties of the same nucleoside and thus can be considered tandem lesions. Our data report an association between acute stenting and successful reperfusion rates in stroke patients with tandem lesion treated with MT. Further studies are warranted to determine the intracranial bleeding risk after MT and stenting according to the antiplatelet therapy. 2008-04-08 2021-01-28 2018-09-21 BackgroundTo evaluate the acute and long-term results of 'tandem lesion' coronary angioplasty in the left anterior descending artery, and to identify the determinants of restenosis.

They have been compensated for time and • Long lesion indicates large atherosclerotic burden and so more cardiac events •A tandemlesion:is two lesions close to each others with a normal segment in between.
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

In tandem occlusion, the primary cause of symptoms and clinical outcome is thrombus in the intracranial arteries rather than the occlusion of the cervical ICA. Today, standard of care for such intracranial lesions is mechanical thrombectomy with stent retriever combined with thrombolysis.

Our data report an association between acute stenting and successful reperfusion rates in stroke patients with tandem lesion treated with MT. Further studies are warranted to determine the intracranial bleeding risk after MT and stenting according to the antiplatelet therapy. Tandem lesions, which are defined as two contiguously, damaged nucleotides in a single DNA strand, are of significant biological interest.
