This is the first report to our knowledge of the successful treatment of an asymptomatic mycotic aneurysm associated with Balamuthia mandrillaris encephalitis. A 27-year-old male with end-stage renal disease presented with generalized seizures following renal transplantation. MRI demonstrated multiple brain masses and an aneurysm of the cavernous and supraclinoid carotid ...

An 86-year-old female was incidentally discovered with an asymptomatic 5.3 cm infrarenal aortic aneurysm. Preoperative imaging demonstrated the aortic neck to have severe suprarenal and infrarenal angulation. The patient was deemed unfit for open aortic repair due to multiple medical comorbidities. Endovascular treatment was performed with a modified Zenith bifurcated ...

Traditional therapy for pulmonary embolism includes systemic anticoagulation, systemic thrombolysis, catheter-directed thrombolysis / suction catheter thrombectomy, and surgical thromboembolectomy. Currently, the standard treatment for submassive and massive pulmonary embolism involves the use of systemic anticoagulation. However, unlike systemic anticoagulation there is no standard treatment algorithm for the use of thrombolytics ...

The Ross procedure or pulmonary autograft has been frequently used for surgical treatment of aortic valve disease. One considerable disadvantage of the Ross procedure is the involvement of two valves (aortic and pulmonary) in treatment of single (aortic) valve disease. Both the aortic and pulmonary valves are at risk for ...

Visceral artery aneurysms is a rare but important condition associated with significant mortality when rupture occurs. Technological advance has increased the role endovascular therapy plays in their management, particularly in patients whom surgery is considered to pose significant risk. Maintenance of end organ perfusion is vital when selecting the optimal ...

Left aortic arch with aberrant right subclavian artery is the most common congenital vascular anomaly involving the aortic arch. In 60% of cases, the aberrant right subclavian artery arises from a dilated segment of the aortic arch called Kommerell's diverticulum. Aneurysm of the aberrant right subclavian artery is rare; this ...

Renal artery aneurysms (RAA) are rare (general population incidence is 0.09%). At this time, the appropriateness of the type of intervention ‑ surgical or endovascular ‑ is based on single center experiences rather than large randomized trials. Endovascular therapy offers less morbidity but surgery has excellent long-term results. In reality, ...

Carotid blowout is a devastating complication in patients with head and neck malignancy. Various treatments including high risk surgery, carotid stenting or carotid occlusion using either coils or detachable balloons have been described. The key for any treatment is the rapidity at which it can be performed. We describe treatment ...

Arterial ischemic stroke occurs as a result of abnormal clinical circumstances that alter hemostasis and cause thrombosis, either within a vessel or as an embolic event. Understanding normal hemostasis, including differences between children (developmental hemostasis) and adults, will provide background for determining the pathophysiology of stroke and potential treatments.

Thoracic endovascular aortic repair (TEVAR) is an important surgical option for the emergency treatment of ruptured thoracic aortic aneurysms, but is associated with a risk of spinal cord ischemia (SCI). Although risk factors for the development of SCI have been well described, the effectiveness of treatment to increase spinal cord ...

An anastomotic false aneurysm is a well known complication after femoral artery surgery. Open surgical repair is the treatment of choice for anastomotic femoral aneurysms, but this can be challenging, unsuccessful, or even impossible. Endovascular repair is an alternative in these cases, but the delivery of a stent-graft in the ...

Background Percutaneous coronary intervention with stent implantation is limited by the occurrence of re-stenosis and the risk of stent thromboses. Objective To define the impact of paclitaxel-coated balloon angioplasty plus endothelial progenitor cell capturing (EPC) stent implantation in de novo coronary artery disease. This combination may reduce neointimal proliferation within ...

The high rate of restenosis associated with percutaneous coronary intervention (PCI) procedures can be reduced with the implantation of metallic stents into the stenotic vessels. The knowledge that neointimal formation can result in restenosis after stent implantation led to the development of drug-eluting stents (DES) which require long lasting antiplatelet ...

Background: The optimal treatment of bare metal stent restenosis is still not defined. The most employed contemporary option is the implantation of a drug-eluting stent (DES). However, this procedure implies the addition of a second metal layer in the vessel wall, which is linked to delayed healing. Furthermore, there may ...

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 ...

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 ...

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) ...
