In this study, a rat carotid balloon injury-animal model was used to elucidate the temporal relation of hypertrophy in the progression of cardiac damage and the role of IGF-I survival pathway on course of the cardiac damage. Rats were subjected to carotid balloon-injury and examined at different time points. We further studied the heart-weight/body-weight-ratio, histology and protein expression to understand the pathological events associated with percutaneous transluminal coronary angioplasty (PTCA) induced damages...

BACKGROUND: One-month dual antiplatelet treatment, with aspirin and clopidogrel, following internal carotid artery stent placement is the current standard of care to prevent in-stent thrombosis. Cilostazol, an antiplatelet drug, has been demonstrated to have a safety profile comparable to aspirin and clopidogrel. OBJECTIVE: To evaluate the safety and clinical efficacy of cilostazol and aspirin therapy following internal carotid artery stent placement up to 1 month postprocedure...

OBJECTIVE: High-degree stenosis of both innominate (IA) or left common carotid artery (CCA) and carotid bifurcation is uncommon but still represents a significant challenge to interventionists in many aspects including techniques, timing, and priority. There are several strategies for intervention that have been reported in the literature. A well-described, less-invasive strategy for extracranial tandem carotid lesions is concomitant carotid endarterectomy (CEA) with retrograde carotid angioplasty and stenting (CAS)...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...

BACKGROUND AND AIMS: Carotid plaque size and the mean common carotid intima-media thickness measured in plaque-free areas (PF CC-IMTmean) have been identified as predictors of vascular events (VEs), but their complementarity in risk prediction and stratification is still unresolved. The aim of this study was to evaluate the independence of carotid plaque thickness and PF CC-IMTmean in cardiovascular risk prediction and risk stratification. METHODS: The IMPROVE-study is a European cohort (n = 3703), where the thickness of the largest plaque detected in the whole carotid tree was indexed as cIMTmax...

Neointima formation, which occurs after vascular injury due to vascular disease or interventions such as angioplasty and stent placement, is a complex process that involves multiple molecular and cellular mechanisms. The inhibition of neointima formation is vital to prevent restenosis of blood vessels. In the present study, we investigated whether the systemic administration of mitoxantrone can inhibit neointima formation, and evaluated the underlying mechanisms under in vitro and in vivo experimental conditions...

The present study was undertaken to examine the relationship between the level of the intensity of the ultrasonic signal reflected from atherosclerotic plaques (ATP) of carotid arteries and the risk for formation of an ischaemic lesion in the brain matter, detected during diffusion-weighted magnetic resonance imaging (DW-MRI) performed 24 hours after carotid endarterectomy (CEA) or carotid angioplasty and stenting (CAS). Our prospective study included a total of 78 patients presenting with stenosis of the sinus of the interior carotid artery...

We report the fifth case of bilateral persistent primitive hypoglossal arteries in the literature. This is also the first such case to be demonstrated on computerized tomography angiogram (CTA) and the first case to be associated with a symptomatic carotid thrombus. The sub-occlusive thrombus was distal to the take-off of the dominant persistent hypoglossal artery (PHA) from the internal carotid artery, thus sparing involvement of posterior circulation. Timely identification of the internal carotid artery thromboembolism in the setting of a PHA is important to allow for thrombectomy...

Carotid endarterectomy (CEA) reduces the risk of stroke in patients with internal carotid artery stenosis, although the optimal surgical technique is debated. The literature suggests that patch angioplasty reduces complication risk, although primary closure shortens cross-clamp time and eliminates complications associated with grafts. The objective of this study was to assess the complication rate after CEA with primary closure. Retrospective review of 240 consecutive patients between 2002 and 2010. Of these patients, 70% returned for follow-up visits for at least 2 or more years...

OBJECTIVE The Pipeline embolization device (PED) is frequently used in the treatment of anterior circulation aneurysms, especially around the carotid siphon, with generally excellent results. However, the PED has its own unique technical challenges, including the occurrence of device foreshortening or migration leading to prolapse into the aneurysm. The authors sought to determine the incidence of this phenomenon, the rescue strategies, and outcomes. METHODS Four institutional databases of neuroendovascular procedures were reviewed for cases of intracranial aneurysms treated with PEDs...

OBJECTIVES: To analyze the procedural and clinical outcomes of carotid artery stenting (CAS) in the hands of endovascular trained vascular surgeons. METHODS: Between April 2008 to May 2013, 1197 patients were treated for extracranial internal carotid artery (ICA) stenosis. The proportion of endovascular treated patients was 5.0% (CAS n = 60 vs. carotid endarterectomy (CEA) n = 1137). All patients in the CAS group (44 males, median age 70 years) were treated by two senior vascular surgeons experienced in endovascular methods...

BACKGROUND: A few other studies have reported the effects of anatomical and technical factors on clinical outcomes of carotid artery stenting (CAS). This study analyzed the effect of these factors on perioperative stroke/myocardial infarction/death after CAS. METHODS: This was a retrospective analysis of prospectively collected data of 409 of 456 patients who underwent CAS during the study period. A logistic regression analysis was used to determine the effects of anatomical and technical factors on perioperative stroke, death, and myocardial infarction (major adverse events [MAEs])...

Carotid artery stenting is commonly used to treat carotid artery stenosis. However, carotid in-stent restenosis remains a challenging problem. Herein, we report a difficult case of recurrent severe carotid in-stent restenosis with total contralateral internal carotid artery occlusion treated with repeat drug-eluting balloon inflations. The outcome after one year of follow-up showed a good result.

INTRODUCTION: To date all published studies analyzing simultaneous treatment of carotid and proximal atherosclerotic lesions are describing retrograde approach and several technical variations. In the presented study, for the first time antegrade approach is described for simultaneous carotid endarterectomy (CEA) and associated brachiocephalic trunk (BCT) or common carotid artery (CCA) angioplasty in the hybrid operating room. METHODOLOGY: From January 2012 till January 2016 antegrade hybrid procedures were performed in 18 patients...

Background The aim of the study was to assess the efficacy of balloon angioplasty-assisted mechanical thrombectomy without urgent stenting in the carotid artery as another approach for endovascular treatment of tandem occlusions. Methods Fifteen consecutive cases of tandem occlusions treated with the endovascular approach between January 2014 and May 2016 were reviewed. The study cohort included patients with an etiology of large vessel atherosclerosis. Extracranial carotid stenting was performed in another session if post-thrombectomy mRS modified Rankin Score (mRS) was 0-2...

An 8-month old female presented with spontaneous subarachnoid hemorrhage and was treated successfully with endovascular coil embolization of the ruptured aneurysm. Transcranial Doppler ultrasound performed four days later demonstrated middle cerebral artery (MCA) velocities greater than 350 cm/sec on the right and greater than 200 cm/sec on the left, despite medical management. The patient demonstrated no focal neurological deficits, though examination was limited by our patient's sedation and intubation. Angiography revealed severe vasospasm of the supraclinoid internal carotid and MCA territories, bilaterally...

Fibromuscular dysplasia (FMD) is a noninflammatory disease affecting small- and medium-sized arteries of the renal and the carotids. It affects the renal arteries in nearly 60%-75% cases. The primary clinical manifestation of renal FMD is hypertension. Medial fibroplasia represents the most common dysplastic lesion. We report two cases who presented with hypertension and renal insufficiency and on evaluation was found to have bilateral renal artery stenosis. Stenting of the renal vessels was not possible due to the narrowed caliber of the vessel and inability to cannulate the renal arteries...

A vascular surgeon is consulted to evaluate a patient because of carotid stenosis. By the time the surgeon enters the examining room or arrives at the bedside, he (she) is aware of the sex and age of the patient as well as the severity of the stenosis on a recent high-quality imaging study. After asking if the patient has had any related symptoms and how long ago they occurred, the surgeon has all of the information that is necessary to determine, in the absence of serious comorbidities, whether this patient is an appropriate candidate for carotid intervention and even how quickly it should be performed...
