Carotid atherosclerotic plaque occurs predominantly at the outer wall of carotid sinus, and computational fluid dynamics (CFD) plays important roles in explaining plaque formation. This study was to investigate the hemodynamic factors in affecting carotid atherosclerotic stenosis.
We report four cases of painful Horner's syndrome due to carotid artery dissection. A lesion on oculosympathic pathway causes Horner's syndrome. A painful Horner's syndrome needs a prompt exploration by tomodensitometry or magnetic resonance imaging to exclude carotid artery dissection. Actually, carotid artery dissection leads to stroke or cerebral ischemic symptoms, mainly in the first two weeks. The treatment is based on anticoagulants or antiplatelet agents.
Vascular and osteological parameters, such as the heights of the carotid bifurcation and distal end of the plaque, are important preoperative considerations for patients undergoing carotid stenosis procedures such as carotid endarterectomy. However, for patients with contrast contraindications such as allergies or nephropathies, three-dimensional computed tomography angiography (3D-CTA) is unavailable, and preoperative evaluation remains challenging. In the present study, we aimed to develop a preoperative ...
The dynamic displacement of the carotid arteries with interference of the hyoid bone during swallowing, named as "flip-flop" phenomenon (FFP), may be associated with ischemic stroke. However, the extent to which FFP is prevalent in carotid artery disease remains unknown. We aimed to investigate its exact prevalence to explore the relationship between FFP and carotid artery disease.
Carotid endarterectomy (CEA) requires complete control of the blood backflow. An anomalous ascending pharyngeal artery (AphA) has been reported to result in incomplete control of the blood flow during CEA. Here, we present a case of symptomatic right internal carotid stenosis for which CEA was performed. An anomalous AphA was confirmed based on its origin from the distal internal carotid artery (ICA) on 3-dimension rotational angiography (3DRA). The anomalous AphA arised near the distal end of the plaque, a...
The external carotid artery (ECA) is inadvertently occluded during carotid endarterectomy (CEA). The importance of ECA occlusion has been emphasized as a loss of extracranial to intracranial collaterals, a source of chronic embolization, or a site for extended thrombosis during wound closure. This study aimed to determine whether ECA occlusion that inadvertently developed during endarterectomy and that was eventually detected using blood flow measurement of the ECA after declamping of all carotid arteries i...
Persistent carotid-basilar connections have a prevalence of 0.14%. Recognizing such persistent fetal anastomoses between the carotid and the vertebrobasilar circulation is of great importance since they are reportedly associated with an increased prevalence of intracranial aneurysms. We report the case of a 15-year-old female who presented with a WFNS grade 5 subarachnoid hemorrhage from an aneurysm at the junction of a persistent primitive hypoglossal artery and the posterior inferior cerebellar artery ori...
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral blood flow has been measured twice following carotid artery stenting in few previous studies, with some discrepancies in the results. The purpose of this study was to measure cerebral blood flow at multiple time points after carotid artery stenting, and to ...
To characterize patients with internal carotid occlusion (ICO) with respect to demographic data, associated diseases, medical management and risk factors and to compare these patients with those with non-significant stenosis (NSS; less than 50% stenosis). Secondary end-points were new neurologic events, progression of contralateral degree of stenosis and cardiovascular symptoms and death during follow-up.
ST2 represents an interesting bio-marker associated with the progression of atherosclerotic disease.
Presented herein is the world experience of surgical treatment and various tactical approaches in a combined lesion of the extracranial and intracranial portions of the internal carotid artery (ICA): a combination of its stenosis or occlusion with vascular malformation of the brain (a cerebral aneurysm, pathological anastomoses, arteriovenous malformations). Also pointed out is the prevalence of the pathology involved, followed by describing various types of surgical policy in this condition: staged and sim...
Randomized trials have failed to show clinical benefit in patients with atherosclerotic renal artery stenosis who were treated with angioplasty with or without stenting. However, these studies were done in patients with a high-grade stenosis. This paper examines whether there are arguments to consider patients with low-grade stenosis for angioplasty.
Researches involving arterial pressure measurements in mice have primarily relied on carotid arterial catheterization. However, in some circumstances, measuring arterial pressure through the carotid arterial impairs accuracy. This study was aimed to evaluate whether femoral artery could displace carotid artery for the blood pressure (BP) measurements in mice. Fifty-six Swiss mice (n = 14 in each group) were randomized into four groups: control, left femoral artery, right femoral artery, and union group, ...
A 66-year-old patient presented at our institution due to therapy refractory hypotension with a history of postural pre-syncope 7 years after supraaortic debranching and TEVAR of the transverse arch. Arterial angiography with invasive BP measurement revealed pronounced hypertension of the lower body (BP: 270/120 mmHg) and subtotal prosthetic graft stenosis of the bypasses to the innominate artery and to the left common carotid artery. Open reoperation for removal of the stenosed Y-limb prosthesis and extraa...
Carotid Doppler sonography (CDS) has been routinely used in the screening for restenosis after carotid artery stenting (CAS) by applying the criteria of flow velocity, however, computed tomography angiography (CTA) enables us to detect restenosis directly and has some advantages that help to overcome the limitations of CDS. We aimed to investigate the incidence of restenosis with CTA and to identify factors related to restenosis after CAS.
Aneurysms of the ophthalmic artery (OA) within the orbit and optic canal are extremely rare. Given the peripheral location of these aneurysms and the fact that most are fusiform, parent artery occlusion is preferred for symptomatic aneurysms. However, the impact of OA occlusion on vision is not always innocuous. Balloon occlusion testing (BOT) of the OA has the potential to gauge the possibility of visual compromise, in addition to assessing collaterals. While BOT has been assessed for carotid artery occlus...
Anomalous origins of the vertebral arteries are uncommon and typically associated with other abnormalities of the great vessels. We present a case of an isolated origin of the right vertebral artery from the ipsilateral common carotid artery detected using magnetic resonance angiography. Such variants can significantly affect endovascular and surgical planning.
A carotid artery pseudoaneurysm in an irradiated neck is a rare entity with possible devastating results and management should be multidisciplinary. We present a successful endovascular treatment of a late carotid artery pseudoaneurysm following patch endarterectomy and cervical radiotherapy.
Giant ruptured paraclinoid aneurysm with concomitant bilateral internal carotid artery dissection (CAD) could be a very difficult condition to be treated with the current surgical and endovascular techniques. Paraclinoid internal carotid artery (ICA) aneurysms remain a major challenge for vascular neurosurgeons. There are still controversies in the management of carotid artery dissections. Surgical and endovascular treatment is recommended in cases with multi-vessel dissections or those complicated by subar...
Antithrombotic treatment plays a key role in stroke prevention, but their direct effects on the composition of carotid artery atherosclerotic plaques are unknown. To investigate the association of antithrombotic treatment with carotid artery plaque composition, with a specific focus on an intraplaque haemorrhage (IPH).
Orbital infarction syndrome (OIS) is a rare entity defined as ischemia of all intraorbital and intra-occular structures including the optic nerve, extraocular muscles and orbital fat. This entity is rare due to rich anastomotic orbital vascularization from both the internal carotid artery and external carotid artery. We report a case of a patient who suffered ENT to the ophthalmic artery and external carotid artery which resulted in orbital infarction syndrome and describe techniques to avoid such complicat...
To evaluate the differences of plaquecomposition and volume between symptomatic and asymptomatic patients with carotid artery stenosis by multi-detector computed tomography angiography (MDCTA).
Increased arterial tortuosity has been suggested as a predisposing factor for carotid artery dissection, which is an important risk factor for development of extracranial carotid artery aneurysms (ECAA). Prior to comparison with non-ECAA controls, the optimal measurement technique should be defined. This study describes the difference between software packages in terms of reproducibility and absolute outcome of arterial tortuosity measurements in ECAA patients.
High-flow bypass with an internal carotid artery to middle cerebral artery bypass using a radial artery graft through the supramandibular-subzygomatic route for a giant internal carotid aneurysm: Technical case report.
A unique case of an internal carotid artery (ICA) giant aneurysm treated by high-flow bypass is presented. This patient had some anatomical variations in the neck region that posed problems for the high-flow bypass, and a new approach to address them is presented.
To examine changes in retinal ganglion cell complex (GCC) and peripapillary retinal nerve fiber layer (RNFL) thicknesses by optical coherence tomography (OCT) in contralateral and ipsilatateral eyes of carotid artery stenosis (CAS) patients before and after carotid endarterectomy (CEA).
