<h3>BACKGROUND AND PURPOSE:</h3> Developments in flat panel angiographic C-arm systems have enabled visualization of both the neurovascular stents and host arteries great detail, providing complementary spatial information addition to conventional DSA. However, visibility these structures may be impeded by artifacts generated adjacent radio-attenuating objects. We report on use a metal artifact reduction algorithm for high-resolution contrast-enhanced conebeam CT follow-up imaging...
<h3>BACKGROUND AND PURPOSE:</h3> Recanalization is observed in 20–40% of endovascularly treated intracranial aneurysms. To further reduce the recanalization and expand endovascular treatment, we evaluated safety efficacy closed-cell SACE. <h3>MATERIALS METHODS:</h3> Between 2007 2010, 147 consecutive patients (110 women; mean age, 54 years) presenting at 2 centers with 161 wide-neck ruptured unruptured aneurysms were by using Inclusion criteria (>4 mm or a dome/neck ratio ≤2). Clinical...
Tentorial dural arteriovenous fistula (DAVF) is a rare vascular disease, which accounts for less than 4% of all cases intracranial DAVF. Because the high risk hemorrhage, patients with tentorial DAVF need aggressive treatment. Management approaches are still controversial, and endovascular treatment has emerged as an effective alternative. In current work, we describe our experience approach in these deep complex tentorium. Eight were treated between January 2006 July 2009. Six (75%)...
<h3>BACKGROUND AND PURPOSE:</h3> Recently, the use of stents to assist in coiling and repair wide-neck aneurysms has been shown be highly effective; however, effect these on RC parent vessel not quantified. The purpose this study was quantify intracranial stenting implanted artery using 3D datasets. <h3>MATERIALS METHODS:</h3> Twenty-four patients receiving FDA-approved neurovascular support coil embolization brain were chosen for study. located ICA, ACA, or MCA. We analyzed C-arm rotational...
While most patients with follicular lymphoma (FL) have excellent outcomes frontline chemoimmunotherapy (CIT), a subset of will experience early progression, which is associated poor subsequent outcomes. Novel biomarkers are needed to identify high-risk earlier. We hypothesized that interim positron emission tomography (PET) would predict progression-free survival (PFS) in this population. retrospectively identified 128 grade 1–3A FL who had an PET after 2–4 cycles CIT at 2 academic centers....
Intracranial stenting with the Wingspan system has been used as a revascularization strategy in symptomatic patients intracranial atherosclerotic disease (ICAD). The latest results of Stenting versus Aggressive Medical Therapy for Artery Stenosis (SAMMPRIS) trial challenge this approach. Our experience treatment ICAD is reported.Patients who underwent were included analysis. Demographic data, periprocedural complications, long term radiological and clinical outcomes are reported.46 lesions...
Pulmonary amyloidosis is an uncommon disease, characterized by extracellular deposition of fibrillary protein in the lungs. It appears three forms: tracheobronchial, nodular pulmonary, and alveolar septal. There are few reports long-term observation primary pulmonary amyloidosis.We present case a 47-year-old man who presented with fever, dyspnea, cough hemoptysis. Chest radiograph computed tomography revealed multiple nodules masses. The patient underwent open lung biopsy, which diagnosed...
<h3>BACKGROUND AND PURPOSE:</h3> Intracranial aneurysms treated by coiling have a risk for recurrence, requiring surveillance imaging. MRA has emerged as an attractive technique postcoiling aneurysm Previous research evaluated MR imaging artifacts of the coil mass in vitro. Our aim this study was to evaluate coiled vivo with time. <h3>MATERIALS METHODS:</h3> Four sidewall were created each 4 dogs. Aneurysms embolized receiving only 1 type coils. After embolization, animals transferred...
Neurofibromatosis type 2 is an inherited autosomal dominant syndrome, characterized by multiple neoplasms of the central and peripheral nervous system associated with ocular abnormalities. The most common tumor disease vestibulocochlear schwannoma (VIII cranial nerve), as many 10% patients this have neurofibromatosis 2. In report we aim to present a 34-year-old male who was seen for bilateral hearing loss. During his workup, which included computer tomography, he found intracranial masses....
Complete surgical resection of intra-axial hypervascular tumors located in the posterior fossa, particular hemangioblastomas, may be challenging due to tumor location, mass effect and excessive bleeding. Embolization these lesions can done preoperatively or as a palliative measure patients who are not candidates. Preoperative embolization reduce intraoperative blood loss, shorten time increase chance complete resection. However, safety effectiveness this procedure is still matter debate....
OBJECTIVE. The purpose of this study was to evaluate the association between diagnostic certainty expressed by wording CT report impressions and subsequent use standard treatment with analgesics versus nonstandard antibiotic administration in patients acute epiploic appendagitis (EA). MATERIALS AND METHODS. Demographic, clinical, radiologic data from a 10-year cohort EA were retrospectively analyzed correlated antibiotics. A level assigned language based on impression statements two...
OBJETIVO: Relatar os resultados preliminares da aplicação técnica de "remodelagem do colo" no tratamento dos aneurismas colo largo artéria renal. MATERIAIS E MÉTODOS: Cinco pacientes (três mulheres e dois homens, com idade média 62 anos, intervalo 49-72 anos) renal variando 10 a 25 mm diâmetro, largo, foram tratados técnicas embolização assistidas por balão durante o período três anos. O microbalão era posicionado diante aneurisma insuflado, temporariamente, colocação das micromolas...
Complex cavernous sinus fistulae (CCF) are a technical challenge to neuro-vascular specialists.Their clinical symptoms usually triad of chemosis, ptosis and exophthalmia 1,2 .Among the most serious visual loss, consequences brain hemorrhage.The commonly performed endovascular treatment consists in embolization through venous approach by inferior petrosal occlusion with coils.Not always conventional route is feasible, imposing alternative routes.We describe two cases CCF treated success using...
Introduction Although coil embolization of brain aneurysms is safe and effective, aneurysm recurrence remains a limitation requiring surveillance imaging. Recently, MR angiography (MRA) has become viable option for non-invasive follow-up. Often, baseline MRA within one week coiling acquired comparison. The mass produces magnetic susceptibility artifact that may obscure the evaluation host vasculature aneurysm. previous research into been done in vitro, dynamic characteristics functional...
