Mycotic aneurysm is a disease requiring immediate treatment because of the high risk of rupture. A difficult surgical approach, especially in the case of occurrence on the iliac artery, involving endovascular embolization and extra-anatomic bypass grafting, is known to be a suitable treatment. We performed extra-anatomic bypass grafting after endovascular ...

Neointimal formation is mediated by phenotypic changes in vascular smooth muscle cells (SMC) and is an important mediator of restenosis following arterial reconstruction. We conjugated antioxidant ginkgolide A (GA) to gold nanoparticles (GNP) to determine the effect of GA delivery on neointimal formation. GA was conjugated to 80 nm GNP ...

Aneurysm of the extracranial carotid artery is a rare condition; mycotic aneurysms are even less common. They always need surgical treatment to prevent possible rupture, embolisation or death. The literature before 1980 mentions ligation as the only treatment for mycotic aneurysms of the carotid artery, obviously with a high morbidity ...

With rapid evolution of endovascular techniques, carotid artery stenting has emerged as an alternative to carotid endarterectomy. Several investigations have been performed that examine the roles of carotid endarterectomy and carotid artery stenting and some trials have sought to compare the two treatment modalities. There have also been advances in ...

Innominate and subclavian artery lesions run a wide spectrum of disease manifestation and treatment options. Since the first surgical treatment, multiple variances have been attempted with the desire to maintain high long-term patency rates while reducing perioperative morbidity and mortality. The advent of endovascular procedures in the 1970s provided the ...

Increased cardiovascular morbidity has become a leading cause of mortality in rheumatoid arthritis (RA). Tumor necrosis factor-alpha (TNFa) inhibitors may influence flow-mediated vasodilation (FMD) of the brachial artery, common carotid intima-media thickness (ccIMT) and arterial stiffness indicated by pulse-wave velocity (PWV) in RA. To assess the effects of adalimumab treatment ...

Epistaxis is a common disorder affecting equally both genders. Posterior origin of epistaxis in some instances requires endovascular treatment. Anastomoses between external carotid artery and internal carotid or ophthalmic arteries heighten the risk of stroke or blindness, if particles of polyvinyl alcohol are used for embolization. We report a case ...

This study investigated and summarized endovascular therapeutic strategies for intracranial ruptured aneurysms associated with arteriovenous malformations (AVMs). Between June 2005 and June 2009, we identified 16 aneurysms in 14 hemorrhagic cases of intracranial AVM using digital subtraction angiography (DSA). Of the 16 aneurysms, 14 were ruptured and two were unruptured. ...

The endovascular technique is the gold standard treatment in dural arteriovenous fistulas. Due to the limited number of series published it is difficult to create rigid guidelines in terms of the best endovascular treatment approach. Treatment must be tailored to each particular case, but it is important to keep in ...

Introduction Endovascular coil embolization has an established role alongside microsurgical clipping in the treatment of aneurysms. We studied previously clipped aneurysms that presented as subarachnoid hemorrhage and were treated by coil embolization. Methods A retrospective review was performed of two prospectively maintained databases from two institutions (Cleveland Clinic, Emory University) ...

Background Spontaneous fusiform aneurysms of the middle cerebral artery (sfaMCA) are quite uncommon and tend to occur in young adults. The use of superselective angiography for ruptured and unruptured aneurysms can help delineate vital angioarchitecture and assist with perioperative planning and treatment modality. The use of superselective Wada testing (SWT) ...

Endovascular coiling has become the primary treatment modality for the treatment of intracranial ruptured aneurysms in many centers. A multicenter randomized controlled trial (RCT), ISAT study, has demonstrated that endovascular coiling of ruptured intracranial aneurysms has benefits over surgical clipping in those patients suitable for either treatment. Because RCT comparing ...

The present case illustrates pulmonary vein isolation guided by real-time three-dimensional transesophageal echocardiography. This imaging modality allowed to navigate in a point-by-point fashion around pulmonary veins to assess both catheter location in relation to pulmonary vein ostia and stability of catheter tip. Also, it offered high-resolution visualization of a thickened, ...

Introduction Current models for the endovascular treatment of aneurysms often require the use of adjuvant devices. Balloon-assisted techniques require temporary occlusion of the parent vessel. Intravascular stents require the use of antiplatelet medication. A novel device that achieves temporary neck protection without parent vessel occlusion or antiplatelet medication is examined ...

Pseudo aneurysm (PSA) of femoral artery is the second common post puncture complication. If PSA is less than 18 mm, it can be closed spontaneously and it can be asymptomatic. If not, it needs treatment. The most common non invasive method used in the treatment is ultrasound guided compression (UGC) ...

Conventional absolute contraindications to catheter-directed thrombolysis include active or recent hemorrhage and the presence of local vascular infection, both of which increase the risk of procedure-related complications such as bleeding and systemic sepsis. For this reason, lytic therapy of arterial thromboembolism under these circumstances is generally precluded. Herein, we describe ...

Aneurysm treatment using flow diversion could become the treatment of choice in the near future. While such side-wall aneurysm treatments have been studied in many publications and even implemented in selected clinical cases, bifurcation aneurysm treatment using flow diversion has not been addressed in detail. Using angiographic imaging, we evaluated ...

The results of endovascular treatment of symptomatic intracranial arteriosclerotic stenosis with stenosis grades exceeding 70% show a mortality rate of 2% and severe morbidity of 8.3%. This justifies treatment being performed by experienced interventionalists only in selected cases, if the prospective outcome of pharmacotherapy alone indicates a higher risk (i.e., ...

Cerebral vasospasm complicating aneurysmal subarachnoid hemorrhage is a well-known medical entity. The delayed ischemic neurological deficits (DIND) as a result of vasospasm remain the main cause of morbidity among patients who manage to survive this severe disease pattern. When the traditional treatment options, either medical or interventional, fail to reverse ...

Based on numerous reports citing high sensitivity and specificity of non-invasive imaging [e.g. computed tomography angiography (CTA) or magnetic resonance angiography (MRA)] in the detection of intracranial aneurysms, it has become increasingly difficult to justify the role of conventional angiography [digital subtraction angiography (DSA)] for diagnostic purposes. The current literature, ...

Recanalization of acute large artery occlusions is a strong predictor of good outcome. The development of thrombectomy devices resulted in a significant improvement in recanalization rates compared to thrombolytics alone. However, clinical trials and registries with these thrombectomy devices in acute ischemic stroke (AIS) have shown recanalization rates in the ...

Intracranial aneurysms are present in roughly 5% of the population, yet most are often asymptomatic and never detected. Development of an aneurysm typically occurs during adulthood, while formation and growth are associated with risk factors such as age, hypertension, pre-existing familial conditions, and smoking. Subarachnoid hemorrhage, the most common presentation ...

First generation drug-eluting stents (DES) have significantly improved the treatment options for patients with symptomatic coronary artery disease by decreasing rates of restenosis after percutaneous coronary revascularisation procedures. However, early enthusiasm was tempered by reports of late stent thrombosis, primarily in "off-label" use. In particular, the treatment of atherosclerotic plaques ...
