Considerable efforts have been placed on the development of degradable microspheres for use in transarterial embolization indications. Using the guidance of the U.S. Food and Drug Administration (FDA) special controls document for the preclinical evaluation of vascular embolization devices, this review consolidates all relevant data pertaining to novel degradable microsphere technologies for bl...

OBJECTIVES Massive hemoptysis is a major clinical problem associated with high morbidity and mortality. Transcatheter arterial embolization is widely used for the treatment of massive hemoptysis, but it was reported that the recurrence rate after embolization is 12-54% in the previous studies. We evaluated the therapeutic effect of transcatheter arterial embolization for the treatment of massiv...

Objetive: To describe the clinical-epidemiological characteristics and management of Cerebral Arteriovenous Malformations (cAVM) in patients treated at San Borja National Institute Child Health (SB – NICH). Materials methods: Retrospective, descriptive study diagnosed with cAVM SB - NICH from 2015–2017. Data was processed analyzed version 22 SPSS software. Qualitative variables were expressed a...

Clinical experience with a new embolization and perfusion microballoon catheter system is presented in 34 patients with angiomas, arteriovenous fistulas, and cerebral hemorrhages. The system uses two separate balloon tips, one for detachment as an embolus and one for perfusion of elastomer. The criteria for catheter and perfusate selection are described. One permanent complication, two temporar...

OBJECTIVE Characterization of magnetic (MRI) features in women undergoing uterine fibroid embolization (UFE) and identification of clinical correlates in an African population. MATERIALS AND METHODS Patients with symptomatic fibroids who are selected to undergo UFE at the hospital formed the study population. The baseline MRI features, baseline symptom score, short-term imaging outcome, and m...

We report a case of an uncommon giant pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis. It presented with a perfused volume of 17.3 cm(3) close to the branch-off of the right hepatic artery. Superselective transcatheter embolization including interlocking detachable coils and a mixture of Ethibloc and Lipiodol was our technique of choice. Following the procedure, th...

In infants, the embolization of liver hemangiomas with congestive heart failure demonstrates therapeutic efficiency by the rapid resolution of heart failure. This is because of the collaterals between the hepatic artery and the hepatic veins. In adults, heart failure due to a giant hemangioma is very rare and the most common indication in adults is a kind of pain in the trunk. The expectation f...

  Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females) who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients inc...

OBJECTIVE To describe the use of renal angiography in the detection of renal vascular injuries following percutaneous nephrolithotomy and to assess the efficacy of endovascular management of these complications. MATERIALS AND METHODS This was a retrospective review of 159 consecutive patients over a period of 12 years from 2005 to 2016 who presented with significant post nephrolithotomy hemor...
