ABSTRACT 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 lesions that are unresectable and not responsive to other therapies. Since it is a new technology still restricted to very few hospitals […]

Intra-arterial fibrinolysis for the management of acute ischemia on a below-knee amputation stump. Case report

Breno Boueri Affonso, Joaquim Maurício da Motta-Leal-Filho, Rafael Noronha Cavalcante, Priscila Mina Falsarella, Francisco Leonardo Galastri, Rodolfo Souza Cardoso, [...]

ABSTRACT Preservation of the knee joint has enormous advantages in terms of mobility and rehabilitation of an amputee. Any cause of breakdown requiring revision to an above-knee amputation is a major setback because it reduces the patient’s rehabilitative potential. We report a case of intra-arterial thrombolysis use to save a below-knee amputation stump with acute ischemia. A 56-year-old man who sought the emergency department with 1-day history of acute pain on his right below-knee stump. The angiography confirmed popliteal artery […]

Percutaneous treatment of complex biliary stone disease using endourological technique and literature review

Fernando Korkes, Ariê Carneiro, Felipe Nasser, Breno Boueri Affonso, Francisco Leonardo Galastri, Marcos Belotto de Oliveira, [...]

Most biliary stone diseases need to be treated surgically. However, in special cases that traditional biliary tract endoscopic access is not allowed, a multidisciplinary approach using hybrid technique with urologic instrumental constitute a treatment option. We report a case of a patient with complex intrahepatic stones who previously underwent unsuccessful conventional approaches, and who symptoms resolved after treatment with hybrid technique using an endourologic technology. We conducted an extensive literature review until October 2012 of manuscripts indexed in PubMed on […]

Minimally invasive treatment of hepatic adenoma in special cases

Felipe Nasser, Breno Boueri Affonso, Francisco Leonardo Galastri, Bruno Calazans Odisio, Rodrigo Gobbo Garcia

Hepatocellular adenoma is a rare benign tumor that was increasingly diagnosed in the 1980s and 1990s. This increase has been attributed to the widespread use of oral hormonal contraceptives and the broader availability and advances of radiological tests. We report two cases of patients with large hepatic adenomas who were subjected to minimally invasive treatment using arterial embolization. One case underwent elective embolization due to the presence of multiple adenomas and recent bleeding in one of the nodules. The second […]

Endometrium evaluation with high-field (3-Tesla) magnetic resonance imaging in patients submitted to uterine leiomyoma embolization

Monica Amadio Piazza Jacobs, Felipe Nasser, Eduardo Zlotnik, Marcos de Lorenzo Messina, Ronaldo Hueb Baroni

DOI: 10.1590/S1679-45082013000100011

Objective:To evaluate the endometrial alterations related to embolization of uterine arteries for the treatment of symptomatic uterine leiomyomatosis (pelvic pain and/or uterine bleeding) by means of high-field (3-Tesla) magnetic resonance.METHODS:This is a longitudinal and prospective study that included 94 patients with a clinical and imaging diagnosis of symptomatic uterine leiomyomatosis, all of them treated by embolization of the uterine arteries. The patients were submitted to evaluations by high-field magnetic resonance of the pelvis before and 6 months after the procedure. […]

ABSTRACT Endovascular surgery has presented a high evolution since 1960 with Charles Dotter, who changed the concept of catheter utilization as a mean to diagnose and introduce therapeutic in interventionist vascular environment. The first reports of bleeding control of gastrointestinal and transluminal angioplasty input the development of new techniques for endovascular access, and new materials use, such as microcatheters and embolic agents, become this procedure effective and viable for treatment of several pathologies. The embolization of several organs of human […]
