The history of treatment of intracranial aneurysms dates back to the late 18th century. These early physicians largely based their crude techniques around "wire insertion alone, galvanopuncture (electrothrombosis), and fili-galvanopuncture (wire insertion together with electrothrombosis)," albeit with overwhelmingly unfavorable outcomes. By the end of the 20th century, treatment options progressed to include two highly effective, and safe, procedures: surgical clipping and endovascular coiling. These methods have been found to be effective treatments for a large portion of aneurysms, but there still exists a subset of patients that do not respond well to these therapies...

PURPOSE: The LUNA is a self-expanding ovoid device that serves as an intra saccular flow diverter as well as a scaffold for endothelization across the neck. The objective of this prospective clinical study (9 European centers) aiming to include a total of 63 patients was to evaluate the ability of the AES to occlude intracranial aneurysms while maintaining patency of the parent artery. METHODS: Immediate post-implantation occlusion grade, near-complete, or incomplete, and parent vessel compromise were evaluated...

BACKGROUND AND IMPORTANCE: Trapping with distal revascularization is a therapeutic option for giant aneurysms that cannot be clipped or coiled. In skull base lesions such as meningiomas, arterial encasement is often present, requiring, in some cases, revascularization procedures: extracranial-to-intracranial bypass and more recently intracranial-to-intracranial techniques. These techniques are used only in exceptional cases of tumors in other localizations. CLINICAL PRESENTATION: We report a case of a recurrent malignant frontal falx meningioma with encasement of both pericallosal arteries (PcaAs)...

BACKGROUND AND PURPOSE: Recent advances in endovascular devices have been aimed at providing high density, mesh-like metallic materials across the aneurysm neck, in place of coil technology. Therefore our aim was to report the in vivo preclinical performance of a self-expanding intrasaccular embolization device. MATERIALS AND METHODS: Elastase-induced aneurysms were created in 12 rabbits. Each aneurysm was embolized with a Luna AES. DSA was performed preimplantation; 5, 10, and 30 minutes postimplantation; and at 1 month in 12 rabbits and at 3 months in 8 rabbits...

Before thrombolytic treatment for acute ischemic stroke is undertaken, conditions associated with increased risk of hemorrhagic complications, such as an acute aortic dissection (AAD), should be excluded. We report an 80-year-old woman with acute ischemic stroke as the sole clinical manifestation of AAD who was treated with intravenous (IV) tissue plasminogen activator (tPA). She had no history of hypertension or any signs or symptoms suggestive of AAD. After IV tPA infusion was started, carotid color-coded duplex sonography demonstrated proximal left common carotid artery dissection suggestive of AAD...

BACKGROUND: Papillary fibroelastoma is a rare benign tumor characterized morphologically since first being described in 1976. Nevertheless, this tumor can be presented with a variety of clinical manifestations, making diagnosis challenging for the physician. There are no gender or age preferences but it is diagnosed by site of presentation along with macro- and microscopic characteristics. CASE REPORT: We report the case of a male patient with a history of type 2 diabetes mellitus and arterial hypertension who was admitted to the hospital with a diagnosis of ischemic heart disease accompanied by sustained ventricular tachycardia...

Aneurysmal bone cyst is a benign but locally destructive lesion of bone. We present two cases of ABC in uncommon locations in two children. The first case concerns a 14 year old boy who had a mass located in the internal side of the talus. An ABC type V of Campanacci's classification is diagnosed. Complete curettage was carried out with a high-speed burr. We implanted an Orthofix external fixation with a mobil bottom bolster and distal pins located in the calcaneum. Case 2 concerns an ABC in the clavicle of a 9 years old boy...

Spontaneous coronary artery dissection is an unusual cause of acute coronary syndrome. We describe a series of cases that with an early diagnosis and aggressive treatment, which includes percutaneous angioplasty with stent implantation and cardiac surgery, had a good outcome. The objective was to study the demographic characteristics, clinical settings, treatments, and inhospital course of patients with spontaneous coronary artery dissection. We studied a retrospective case series in 3 coronary care units in third-level university hospitals...

BACKGROUND: To assess the impact of preliver transplant double helical computed tomography (DHCT) and three-dimensional computed tomography arteriography (3D-CTA) on surgical planning for hepatic transplantation. METHODS: Vascular findings detected on DHCT/3D-CTAs of 80 patients were shown to the transplant surgeon in a blinded fashion. These findings included hepatic arterial anatomy, diameters of the major vessels that supplied the liver, celiac axis stenosis, splenic artery (SA) aneurysms, and portal vein thrombosis (PVT)...

BACKGROUND: Thoracic aortic aneurysms (TAAs) and valvular insufficiency, the main cardiovascular lesions in Marfan's syndrome, are associated with destruction of connective tissue; however, their pathogenesis remains unclear. METHODS AND RESULTS: To test the hypothesis that changes in the activity of the matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are responsible for the damage to connective tissue in these lesions, histochemical studies of the immunoreactivity (IR) for MMPs and their tissue TIMPs (MMP-1, MMP-2, MMP-3, MMP-9, TIMP-1, and TIMP-2) were made in TAAs (n = 7) and aortic valves (n = 5) from 7 patients with Marfan's syndrome...

COMPARATIVE STUDY
B Adye, G Luna
BACKGROUND: True aneurysms of the abdominal aorta and its branches are at least in part due to defects in the structural integrity of the arterial wall. Whether the defect is isolated to the vascular wall is unclear. If the structural weakness involves other tissues, patients with aneurysmal disease should have a higher incidence of collagen and fascial defects, such as abdominal and inguinal hernias. METHOD: We reviewed 100 patients who underwent elective aortic reconstruction for aneurysmal or occlusive disease...

A few patients with traumatic aortic laceration remain undiagnosed and survive long enough to develop a chronic aneurysm. Such aneurysms are frequently asymptomatic; alternatively, they may manifest themselves in the form of chest pain, dysphonia, dysphagia, bronchial irritation, or sudden death. A case of aortobronchial fistula secondary to a chronic post-traumatic aneurysm of the aortic isthmus is presented. Hemoptysis was the main sign. The affected segment of the thoracic aorta was replaced with a Dacron graft and a left superior lobectomy was performed...

C Reimers, A Van Tosh, M Berger, E Luna, S F Horowitz
Radionuclide ventriculography is an accepted method for diagnosing left ventricular aneurysms, but false-negative studies have been associated with a mural thrombus filling the left ventricular cavity. We describe a patient with a left ventricular aneurysm due to myocardial infarction whose aneurysm scintigraphically "disappeared" from serial radionuclide ventriculograms. This was documented echocardiographically and pathologically to be due to the formation of a large mural thrombus. Review of the literature suggests that radionuclide ventriculography and echocardiography may be complementary techniques in the diagnosis of left ventricular aneurysm...

The major vascular structures in the retroperitoneum are valuable landmarks for the ultrasonographer. Two cases of focal disease, one involving the pancreatic region (an aneurysm of the superior mesenteric artery) and another involving the kidney (a renal arteriovenous fistula) are presented to emphasize the importance of considering a vascular origin in the differential diagnosis of obscure sonolucent masses.
