We report a case of progressive ischemic stroke due to a mobile plaque, in which carotid artery stenting successfully prevented further infarctions. A 78-year-old man developed acute multiple infarcts in the right hemisphere, and a duplex ultrasound showed a mobile plaque involving the bifurcation of the left common carotid artery. Maximal medical therapy failed to prevent further infarcts, and the number of infarcts increased with his neurological deterioration. Our present case suggests that the deployment of a closed-cell stent is effective to prevent the progression of the ischemic stroke due to the mobile plaque.

Background: There are no guidelines for the optimal timing of surgery (emergency vs. delayed) for ascending aortic dissection with acute ischemic stroke. We retrospectively compared the prognoses and radiological and clinical findings for concomitant aortic dissection and ischemic stroke in a series of case reports. Case presentation: Three patients presented with left hemiparesis. Patient 1 underwent surgery for acute aortic dissection without treatment for acute ischemic stroke. In Patient 2, emergency stenting could not be performed due to cardiac tamponade and hypotension. Therefore, emergency acute aortic dissection surgery was performed. Patient 3 underwent emergency right common carotid artery stenting followed by surgery for acute aortic dissection. Brain perfusion computed tomography angiography (CTA) was performed to diagnose severe stenosis of the right common carotid artery or occlusion concomitant with acute aortic dissection involving the aortic arch with a cerebral perfusion mismatch in all the patients. Patient 3 had postoperative local cerebral infarction, whereas patients 1 and 2 (without stent insertion) had extensive postoperative cerebral infarction. Conclusion: Patient 3 showed a better prognosis than patients without stent treatment. We suggest that perfusion CTA of the aortic arch in suspected acute ischemic stroke can facilitate early diagnosis and prompt treatment in similar patients.

The paper presents a case of a patient with floating thrombosis in the right common carotid artery and occlusion of the carotid bifurcation of the right common carotid artery against the background of severe atherosclerosis of the common carotid artery with 70% stenosis. Thrombosis was identified using color duplex ultrasound scanning in an asymptomatic patient. During hospitalization, thrombosis was complicated by a cerebral infarction of the right middle cerebral artery, apparently of embolic origin.

Introduction. Takayasu arteritis is a rare disease affecting the aorta and its main branches, causing arterial claudication and end-organ ischemia, including stroke. The etiology is unknown but is believed to be autoimmune. An association between Takayasu arteritis and tuberculosis has been suggested, but the possible relation is unclear.Case Presentation. A 15-year-old Somali boy was diagnosed with latent tuberculosis. He had a lesion in the right lung, and both the tuberculin skin test by the Mantoux method and Quantiferon GOLD test turned out positive. After he suffered a cerebral infarct in the right hemisphere, childhood Takayasu arteritis was diagnosed. The diagnosis was based on diagnostic imaging showing a high-grade stenosis of the origin of the right common carotid artery, an occluded common carotid artery on the left side, a circumferential thickening of the vessel walls in the right and left common carotid artery, and laboratory findings with elevated C-reactive protein.Conclusion. Takayasu arteritis is an uncommon cause of stroke. It should however be kept in mind as a cause of cerebrovascular disease, especially in the young.

A 75-year-old man with a recent history of transient left hemiparesis and dysarthria was referred to our hospital. Angiography showed right internal carotid artery (ICA) occlusion and left ICA 89% stenosis. Positron emission tomography (PET) showed decreased cerebral blood flow (CBF), and increased oxygen extraction fraction (OEF) and cerebral blood volume (CBV) in the right hemisphere. In the left hemisphere, CBV was increased, but CBF and OEF remained normal. One month after the transient ischemic attack, left carotid artery stenting (CAS) was performed without complications. Diffusion-weighted magnetic resonance imaging (MRI) on the day after CAS showed no fresh ischemic lesion. PET on the second day after CAS showed increased CBF and decreased OEF and CBV in the right hemisphere as compared with those before CAS. In the left hemisphere, decreased CBV was observed and CBF was slightly increased as compared with those before CAS. The postoperative course was uneventful, but on the fifth day after CAS, the patient suddenly showed a focal seizure and right motor weakness. Emergency computed tomography scanning showed massive intracranial hemorrhage with severe brain edema in the left hemisphere. Although CBF study is useful to predict the hyperperfusion syndrome, we cannot disregard the possibility of intracerebral hemorrhage after CAS for carotid artery stenosis when there is no evidence of hyperperfusion on postoperative CBF study.

Background We experienced two cases of ischemic stroke resulting from carotid artery occlusion associated with acute type A aortic dissection (ATAAD), in which carotid artery stenting before the surgery for ATAAD resulted in good clinical outcomes. Case 1 description: A 63-year-old woman was hospitalized for conscious disturbance, right hemiparesis, and total aphasia. Computed tomography of the head showed no abnormal findings. Computed tomography angiography showed ATAAD and bilateral common carotid artery occlusion. Surgery was not indicated for ATAAD because of a poor prognosis of ischemic stroke. However, carotid artery stenting of the left common carotid artery occlusion was successfully performed, and her neurological findings improved. The patient underwent hemiarch replacement for ATAAD on the day after carotid artery stenting. Her final modified Rankin Scale was 1. Case 2 Description: A 57-year-old woman was hospitalized for mild left hemiparesis. Magnetic resonance imaging showed right watershed infarction and right common carotid artery occlusion. Computed tomography angiography showed ATAAD. After hospitalization, conscious disturbance appeared and left hemiparesis worsened. Ischemic stroke indicated a poor prognosis for revascularization by surgery for ATAAD. Thus, carotid artery stenting of the right common carotid artery occlusion was performed. The patient’s neurological findings improved and she underwent hemiarch replacement for ATAAD at 19 days after carotid artery stenting. Her final modified Rankin Scale was 1. Conclusions In the present cases, although ischemic stroke was serious and precluded surgical indication for ATAAD, carotid artery stenting before surgery for ATAAD resulted in good clinical outcomes. Performing carotid artery stenting before surgery for ATAAD is challenging but achievable, and is a valid treatment option depending on the individual cases.

Abstract A mobile thrombus in the carotid arteries is a very rare ultrasonographic finding and is usually diagnosed after a neurological emergency, such as a transient ischemic attack or cerebral infarction. We present the case of a 54-year-old man with vascular risk factors (a heavy smoker, untreated hypertension) who was admitted to the emergency unit with right sided hemiparesis and aphasia. A cerebral CT scan showed a left middle cerebral artery territory infarction. The duplex ultrasound examination revealed mild atherosclerotic changes in the right common and internal carotid arteries, right-sided complete subclavian steal phenomenon and a complicated hypoechoic atherosclerotic plaque in the left common carotid artery with a large mobile thrombus. Due to the high embolization risk, the patient was hospitalised and prescribed Aspirin together with low molecular weight Heparin. We recorded an improvement in the patient’s neurological status and the control duplex scan revealed disappearance of the thrombus. The presence of floating thrombus in a patient with clinical and imagistic evidence of stroke is a major therapheutic challenge for the neurologist. The treatment strategies are not standardized and must be individualized, however in our case parenteral anticoagulation proved to be successful.

Background and purpose Placement of a large-bore guiding sheath or catheter into the common carotid artery (CCA) is crucial in transbrachial carotid artery stenting (CAS). Herein, we describe technical tips for the navigation of a 6-French guiding sheath into the CCA using a tri-axial catheter system in transbrachial CAS. Materials and methods A total of 27 patients underwent transbrachial CAS. For the right side, a 6-French straight guiding sheath was navigated directly into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French straight guiding catheter. For the left side, a 6-French Simmons guiding sheath was navigated into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French Simmons guiding catheter. After the placement of a 6-French guiding sheath into the CCA, CAS was performed under distal filter or balloon protection. Results Fifteen patients had a right carotid stenosis and 12 patients had a left carotid stenosis. The 6-French guiding sheath was safely placed with ease and provided adequate stabilization for CAS. All procedures were successfully performed without any complications. Conclusion The use of a tri-axial catheter system for the navigation of a 6-French guiding sheath into the CCA appears safe and efficient, allowing transbrachial CAS, with 6-French guiding sheath stabilization, to be performed without any complication.

Background Brain reperfusion following an ischemic event is essential for tissue viability, however, it also involves processes that promote neuronal cell death. We have recently shown that local expression of the hormone leptin in cardiovascular organs drives deleterious remodeling. As cerebral ischemia-reperfusion (IR) lesions derive expression of both the leptin hormone and its receptor, we hypothesized that blocking leptin activity in the injured brain area will reduce the deleterious effects of IR injury. Methods C57BL6 male mice underwent bilateral common carotid artery and external carotid artery ligation. The right hemisphere was reperfused after 12 minutes, followed by intraarterial injection of either a low-dose leptin antagonist or saline solution via the ipsilateral ICA. The left common carotid artery remained ligated. Fifteen IR/leptin antagonist-injected and fourteen IR/saline-injected mice completed the experiment. Five days after surgery brains were collected and samples of the hippocampal CA1 region were analyzed for cell viability (H&E) and apoptosis (TUNEL and caspase3), for neuroinflammation (Iba1), and for signaling pathways of pSTAT3 and pSmad2. Results The right hemisphere hippocampal CA1 region subjected to IR and saline injection exhibited increased apoptosis and necrosis of pyramidal cells. Also, increased density of activated microglia/macrophages was evident around the CA1 region. Comparatively, leptin antagonist treatment at reperfusion reduced apoptosis and necrosis of pyramidal cells, as indicated by increased number of viable cells (p < 0.01), and reduced TUNEL (p < 0.001) and caspase3-positive cells (p<0.05). Furthermore, this treatment reduced the density of activated microglia/macrophages (p < 0.001) in the CA1 region. Signaling pathway analysis revealed that while pSTAT3 and pSmad2-positive cells were found surrounding the stratum pyramidal in saline-treated animals, pSTAT3 signal was undetected and pSmad2 was greatly reduced in this territory following leptin antagonist treatment (p < 0.01). Conclusions Inhibition of leptin activity in hemispheric IR injury preserved the viability of ipsilateral hippocampal CA1 neurons, likely by preventing apoptosis and local inflammation. These results indicate that intraarterial anti-leptin therapy may have clinical potential in reducing hemispheric brain IR injury.

Management of the symptomatic multiple stenosis of supra-aortic vessels (MSSVs) in a “bovine” aortic arch (BAA) configuration is infrequently reported. The optimal treatment choice remains debatable. A successful hybrid treatment for a proximal critical stenosis of the innominate and left common carotid artery was performed in a high-risk patient with a tandem symptomatic lesion in the right carotid bifurcation and a concentric vulnerable plaque in the bovine trunk. This case supports the feasibility, safety, and efficacy of a combined carotid bifurcation endarterectomy and retrograde kissing stenting of common carotid arteries with cerebral protection after evaluation of radiological, anatomical, and clinical parameters.
