BACKGROUND AND PURPOSE Several endovascular treatment options are available for cavernous carotid aneurysms. We compared pipeline embolization device (PED) versus conventional endovascular treatment in terms of evolution of mass effect, complications, recurrence, and retreatment rate. METHODS One hundred fifty-seven patients harboring 167 cavernous(More)
BACKGROUND The use of flow-diversion to treat ophthalmic segment aneurysms (OSA) has not been well evaluated. OBJECTIVE To assess the visual outcomes, the obliteration rate, and the need for retreatment of OSA treated by the pipeline embolization device (PED). METHODS Patients who underwent treatment with PED for OSA from 2009 to 2014 were selected and(More)
BACKGROUND The main concern with the use of the pipeline embolization device (PED) in treating cerebral aneurysms is the risk of hemorrhagic and thromboembolic complications. OBJECTIVE To investigate if P2Y12 reaction unit (PRU) values are associated with hemorrhagic and thromboembolic complications after treatment with the PED and to find an optimal(More)
BACKGROUND Ambulatory blood pressure (BP) monitoring (ABPM) is a cornerstone in resistant hypertension (RHT) management. However, it has higher cost and lower patients' acceptance than home BP monitoring (HBPM). Our objective was to evaluate HBPM usefulness in the management of patients with RHT. METHODS A total of 240 patients were submitted to 24-hour(More)
The tools for managing retinoblastoma have been increasing in the past decade. While globe-salvage still relies heavily on intravenous chemotherapy, tumors in advanced stage that failed chemotherapy are now referred for intra-arterial chemotherapy (IAC) to avoid enucleation. However, IAC still has many obstacles to overcome. We present an update on the(More)
BACKGROUND The Pipeline Embolization Device is a widely utilized flow diverter in the treatment of intracranial aneurysms. OBJECTIVE To assess the incidence, clinical significance, predictors, and outcomes of in-Pipeline stenosis (IPS). METHODS Angiographic studies in 139 patients treated between 2011 and 2013 were independently reviewed by 2 authors(More)
PURPOSE Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. MATERIALS AND METHODS Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36(More)
OBJECTIVE With the increasing number of aneurysms treated with endovascular coiling, more recurrences are being encountered. The aim of this study was to evaluate the efficacy and safety of microsurgical clipping in the treatment of recurrent, previously coiled cerebral aneurysms and to identify risk factors that can affect the outcomes of this procedure.(More)
The first case of Kawasaki disease in Pernambuco, Brazil, is described. An 18-month-old by presenting with fever, adenomegaly and mucocutaneous rash, had right and left coronary arteries dilation and aneurysm detected on echocardiography. Treated with a high dosage of aspirin, the patient is asymptomatic after a 7-month follow-up, with regression of(More)
