Falsarella,Priscila Mina; Rahal Junior,Antonio; Dórea,Aline Andrade; Muniz Neto,Francisco Júlio; Francisco Neto,Miguel José; Garcia,Rodrigo GobboABSTRACT A 2-year-old female patient, admitted in the emergency room, presented diarrhea for 5 days and bloody stools in the last 24 hours. Physical examination revealed no significant findings. Ultrasound was initially performed, showing an elongated, well delimited and solid mass occupying since right hypocondrium until left iliac fossa, displacing adjacent structures. In sequence, magnetic resonance imaging ...
Evaluation of the blood-oxygen-level-dependent (BOLD) sequence with 3 Tesla dev...
Mendes,Guilherme Falleiros; Falsarella,Priscila Mina; Garcia,Rodrigo Gobbo; Sanches,Liana Guerra; Baroni,Ronaldo HuebABSTRACT Objective To evaluate the ability of blood-oxygen-level-dependent (BOLD) magnetic resonance imaging at 3 Tesla to measure tissue oxygen bioavailability based on R2* values, and to differentiate between acute tubular necrosis and acute rejection compared to renal biopsy (gold standard). Methods A prospective, single-center study, with patients submitted to renal transplantation between 2013 and 2014, wh...
Transesplenic access in the treatment of varicose gastrointestinal bleeding. Ca...
Martins,Rafael Birelo; Falsarella,Priscila Mina; Motta-Leal-Filho,Joaquim Maurício da; Galastri,Francisco Leonardo; Affonso,Breno BoueriABSTRACT Varicose gastrointestinal bleeding is one of the major causes of morbidity and mortality in patients with chronic liver disease. Endoscopic treatment is the first therapeutic line for these patients, however, for those whom this therapeutic modality fail, a broad knowledge of alternative treatment options may improve the prognosis. We describe a case of a patient who were successfully embolized from ga...
Transarterial radioembolization for liver tumors as neoadjuvant therapy: three ...
Carvalho,Vithor de Oliveira; Galastri,Francisco Leonardo; Affonso,Breno Boueri; Falsarella,Priscila Mina; Valle,Leonardo Guedes MoreiraABSTRACT Transarterial radioembolization (TARE) with yttrium-90 microspheres is a palliative locoregional treatment, minimally invasive for liver tumors. The neoadjuvant aim of this treatment is still controversial, however, selected cases with lesions initially considered unresectable have been enframed as candidates for curative therapy after hepatic transarterial radioembolization. We report three cases in w...
Caecal appendix lipomatosis in a pregnant patient mimicking acute appendicitis
Sanches,Laura Pereira; Rahal Júnior,Antônio; Falsarella,Priscila Mina; Carvalho,Vithor de Oliveira; Valle,Leonardo Guedes MoreiraABSTRACT A 34-years-old pregnant woman admitted in the emergency unit complaining about worsening right iliac fossa pain for 2 days. Acute appendicitis was the suspected diagnosis. Laboratory exams were ordered and results were within normal limits for infectious and inflammatory aspects. Ultrasound scan revealed a pregnancy in course without alterations and a thickness of the appendix wall without inflammatory...
Peri-prosthetic infection in the postoperative period of endovascular abdominal...
Martins,Diego Lima Nava; Falsarella,Priscila Mina; Rahal Junior,Antonio; Garcia,Rodrigo GobboABSTRACT Endovascular aneurysm repair is an established technique for treating many infrarenal aortic aneurysms. Infection is one of the most serious complications of this technique, and although percutaneous treatment has been well established for intra-abdominal collections, its use to treat peri-prosthetic fluid collections has not been well determined. In this article we describe a small series of three pat...
Injecting hemostatic matrix in the path of biopsies: efficacy, potential compli...
Rahal Junior,Antonio; Falsarella,Priscila Mina; Ferreira,Vinicius Tadeu Rodrigues; Mariotti,Guilherme Cayres; Queiroz,Marcos Roberto Gomes deAbstract Objective: To describe the technique of injecting hemostatic matrix, as well as the experience of our interventional radiology department in its application. Materials and Methods: We conducted a single-center study with retrospective analysis of the experience of our group in the use of hemostatic gelatin matrix in percutaneous biopsies. Results: In a total of 73 biopsies in different organs, such as ...
Minimally invasive treatment of complex collections: safety and efficacy of rec...
Falsarella,Priscila Mina; Rocha,Rafael Dahmer; Rahal Junior,Antonio; Mendes,Guilherme Falleiros; Garcia,Rodrigo GobboAbstract Objective: To analyze the efficacy of recombinant tissue plasminogen activator (r-TPA) injection in the evolution of percutaneous drainage of thick collections. Materials and Methods: This was a single-center study involving the retrospective analysis of hospitalized patients undergoing percutaneous drainage of thick (superficial or intracavitary) fluid collections, followed by injection of a fibrinoly...
Aspects of images in magnetic resonance of liver tumors treated with transarter...
Affonso,Breno Boueri; Motta-Leal-Filho,Joaquim Maurício da; Cavalcante Jr.,Francisco de Assis; Galastri,Francisco Leonardo; Cavalcante,Rafael NoronhaABSTRACT Transarterial selective internal radiation therapy with yttrium-90, also known as radioembolization, is a therapy based on the administration of resin or glass microspheres loaded with the radioisotope yttrium-90, via selective arterial catheterization of tumor-feeding vessels. It is classified as a type of locoregional therapy and its main goal is to treat patients with primary or secondary hepatic le...
Percutaneous drainage of iliopsoas abscess: an effective option in cases not su...
Martins,Diego Lima Nava; Cavalcante Junior,Francisco de Assis; Falsarella,Priscila Mina; Rahal Junior,Antonio; Garcia,Rodrigo GobboABSTRACT The aim of this study were to describe the technique of percutaneous drainage of iliopsoas abscess, and to discuss the benefits of using this minimally-invasive tool. A single center study with retrospective analysis of patients with psoas abscess confirmed by imaging scans, sent to the interventional medicine center and submitted to computed tomography and ultrasound-guided percutaneous drainage, from...
