Luna aneurysm

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...

We report the case of a 48-year-old woman whose recurrent coital headache ceased following intracranial internal carotid artery aneurysm embolization.

OBJECTIVES: The Pipeline embolization device (PED) (Chestnut Medical Technologies, Inc., Menlo Park, CA) is a new microcatheter-delivered endovascular construct designed to achieve the curative reconstruction of the parent arteries giving rise to wide-necked and fusiform intracranial aneurysms. We present our initial periprocedural experience with the PED and midterm follow-up results for a series of 53 patients. METHODS: Patients harboring large and giant wide-necked, nonsaccular, and recurrent intracranial aneurysms were selected for treatment...

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...

OBJECTIVE: The objective of this study was to present results of surgical repair of left ventricle aneurysms with or without myocardial revascularization and or valve replacement. MATERIAL AND METHODS: We analyzed risk factors, clinical conditions, coronary arteries affected, surgical procedure carried out, morbidity, and mortality in patients with left ventricle aneurysms treated between January 1, 1998 and December 31, 2002. RESULTS: Of 1,620 patients submitted to myocardial revascularization, 24 (18 male and four females), had ventricular aneurysms...

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...

Neoplasms and pseudotumors of the temporomandibular joint (TMJ) are very uncommon. Early recognition of such will prevent therapeutic delay and may have a dramatic impact on patient morbidity and mortality. Included in rare TMJ lesions are the following: 1) synovial chondromatosis, 2) osteochondroma, 3) osteoma, 4) osteoblastoma, 5) pigmented villonodular synovitis, 6) ganglion, 7) synovial cyst, 8) simple bone cyst, 9) aneurysmal bone cyst, 10) epidermal inclusion cyst, 11) hemangioma, 12) nonossifying fibroma, 13) Langerhans cell histiocytosis, 14) plasma cell myeloma, 15) sarcoma...

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...

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...

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.

Aneurysms arising from the extracranial carotid arteries are uncommon lesions. Clinically, they may present as lateral masses in the superior cervical area, as medial masses in the tonsillar fossa or parapharyngeal region, or as a mass palpable in both areas. Tenderness or pain may or may not be present. Pulsation is usually detectable. Embolic neurological episodes are a common event leading to discovery of these lesions. Etiologies include trauma, atherosclerosis, fibromuscular dysplasia, infection, and congenital predisposing factors...

The treatment of inflammatory aneurysms of the abdominal aorta presents a formidable challenge to the surgeon. The retroperitoneal inflammatory reaction obliterates normal tissue planes, limiting access to the infrarenal aorta. During a 70-month period 25 (6%) of 439 patients operated on for abdominal aortic aneurysms were found to have the inflammatory type. These patients were more likely to be symptomatic than patients with noninflammatory aneurysms and they were more likely to be male. Although surgical repair of the aneurysms required longer aortic occlusion time and more blood replacement, the outcome was similar to that for patients treated for noninflammatory aneurysms...

We reviewed our experience with replacement of the ascending aorta and aortic valve with a composite graft and reimplantation of coronary arteries to the tube graft during 8 years interval from April, 1982, to April 1990. 24 patients underwent repair, the mean age was 49.83 years. Annuloaortic ectasia was the most common indication (58.33%), followed by aortic dissection (acute or chronic). Emergency operation was carried out in nine patients with aortic dissection (37.5%) and elective in 15. The mean duration of cardiopulmonary bypass was 118 +/- 4 minutes and of aortic clamping 83...
