The endovascular management of symptomatic atherosclerotic superficial femoral artery (SFA) disease is challenging and requires consideration of unique anatomical, hemodynamic, and biomechanical factors. The current armamentarium of balloon catheters and flexible nitinol bare metal stents have limited long-term efficacy due to intimal hyperplasia resulting in restenosis. Unfortunately, the remarkably low ...

Carotid artery stenosis is a major risk factor for stroke and transient ischemic attack. Although carotid endarterectomy is the established gold standard for carotid revascularization, carotid artery angioplasty and stenting (CAS)-proven by large randomized clinical trials and rigorous registries and supported by improving stent designs, embolic protection, and increasing neurointerventionalist ...

Percutaneous coronary intervention (PCI) is an important treatment approach in the management of symptomatic coronary artery disease (CAD). A significant development in PCI in the mid 1970s was balloon angioplasty, followed by bare-metal stents a decade later, and now, the widespread use of drug-eluting stents (DES). While PCI has conferred ...

Cutting balloon angioplasty is a common treatment modality in the pediatric population for pulmonary artery stenosis. We present an adult with histoplasmosis induced fibrosing mediastinitis resulting in pulmonary artery stenosis that was successfully treated with cutting balloon angioplasty and subsequent stent deployment. Percutaneous endovascular stent placement has be shown to ...

SUMMARY: We report a case of severe RCVS treated with a combination of selective intra-arterial verapamil infusions and intracranial angioplasty, resulting in angiographic and clinical improvement. Endovascular techniques more commonly used in the treatment of SAH-induced vasospasm are potentially important adjuncts to systemic drug therapy in the management of severe ...

Hemichorea associated with carotid artery occlusive disease is extremely rare. It has been recently suggested that carotid artery stenosis should be considered in the differential diagnosis of chorea, even in the absence of a preceding stroke or transient ischemic attack. Although the pathophysiology of this condition is still under discussion, ...

Donor artery dissection is a known cause of technical failure in microvascular anastomosis. A method for detection and direct repair of donor artery dissection before superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis is described using a high magnification operating microscope (maximum 50.4× magnification). Before STA-MCA anastomosis, the ...

Significant occlusions of the peripheral arterial circulation, responsible for chronic limb ischemia (CLI), are a serious cause of morbidity, mortality, and poor quality of life. The currently available treatment options for patients with severely symptomatic CLI include bypass surgery and arterial revascularization. Percutaneous transluminal angioplasty for CLI is shown to ...

Objective. Large calvarial lesions may bleed extensively during their removal. The main vascular supply to such lesions is from branches of the external carotid arteries (ECAs). Bilateral ECA embolisation has been described to reduce the vascularity, and therefore blood loss of such lesions during their surgical removal, but it is expensive ...

Patients with significant carotid disease have an increased risk of stroke during coronary artery bypass grafting (CABG). However, due to its inherent risk and to the variety of mechanisms responsible for postoperative stroke, prophylactic carotid endarterectomy has an uncertain value, particularly in cases of asymptomatic unilateral carotid disease. In addition, ...

Amussat's sign is typically a transverse laceration of the intimal layer of carotid arteries described in cases of hanging. Subtotal laceration of the carotid artery is not strictly specific for hanging and can be also caused by blunt neck trauma, extreme overstretching, or whiplash-injuries. In a prospective autopsy study of ...

Intraluminal thrombus in the carotid artery is often misdiagnosed because clinical imaging, such as angiography and duplex ultrasonography, fails to accurately identify it. Recently, it was reported that optical coherence tomography (OCT), a new imaging modality, can visualize intravascular thrombus in the coronary artery. An 83-year old male was admitted ...
