RESUMO
BACKGROUND: Percutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option. PURPOSE: To report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review. MATERIAL AND METHODS: MEDLINE databases were searched for case reports and series including children and iatrogenic catheter fragments or guidewires retrieved through percutaneous techniques. We also conducted a retrospective analysis of 14 cases from our institution over a 14-year period. A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases. Statistical analyses were performed using Microsoft Excel version 2016. RESULTS: Port catheter fragments and peripherally inserted central catheters (PICCs) were the most embolized foreign bodies and the pulmonary artery was the most common site of embolization in 44.1% of cases. Analysis of the retrieval technique demonstrated a preference for extraction through the femoral vein (81.7%) and using snare techniques (93.5%). The success rate of percutaneous retrieval was 96.6% with only 1.1% of procedure-related complications. Patients were asymptomatic in 77.2% of cases, presented septic complications in 2.3%, and no deaths were reported. Median fluoroscopy time was 10 min (range = 1.7-80 min) and median procedure length was 60 min (range = 35-208 min). CONCLUSION: Percutaneous retrieval of intravascular foreign bodies is a feasible, safe, and efficient technique in children and should be considered the preferred treatment option.

Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepato-logy (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.

Acute nonvariceal upper gastrointestinal hemorrhage is a frequent condition associated with significant morbidity and mortality. Angiodysplasia is a common cause of bleeding in the gastrointestinal tract in the elderly. This case report discusses about a 75-year-old woman clinically stable with melena for 2 years due to arteriovenous fistula of upper mesenteric artery branches without adequate clinical and therapeutic treatment. The goal of this article is to report the safety and efficacy of superselective transcatheter arterial embolization with coils in treating lower gastrointestinal bleeding caused by angiodysplasia that was unresponsive to internal medicine treatment and enteroscopy management.
RESUMO
OBJETIVO: Estudar as alterações hemodinâmicas consideradas normais após a realização da anastomose portossistêmica intra-hepática transjugular (TIPS) e a eficácia dos parâmetros sugestivos de estenose do TIPS com o ultra-som Doppler. MATERIAIS E MÉTODOS: Dezesseis pacientes foram avaliados de maneira prospectiva, no período de dezembro de 2001 a março de 2003. As avaliações foram realizadas 24-48 horas após o TIPS e a seguir em intervalos regulares de 30 dias, três meses, seis meses e um ano, com ultra-som modo B, Doppler pulsado, Doppler colorido e de amplitude em diferentes pontos da prótese relacionados ao TIPS. A angiografia foi realizada apenas para a confirmação dos resultados e terapêutica pertinente. RESULTADOS: Até o momento apenas os achados de fluxo contínuo no terço proximal da prótese e o gradiente de velocidade entre dois pontos da prótese apresentaram significância estatística para o diagnóstico de estenose do TIPS (p < 0,001), mas outros diferentes critérios também estiveram presentes, porém sem significância estatística. CONCLUSÃO: O ultra-som Doppler é uma ferramenta eficaz no diagnóstico da perviedade e das complicações secundárias à realização do TIPS, sobretudo da estenose. No entanto, é necessária casuística maior, a fim de determinar um conjunto de parâmetros que facilite o seguimento destes pacientes, reservando a angiografia apenas para o tratamento pertinente.
