The peripherally inserted central catheter (PICC) is widely used as a central venous catheter for both pediatric and adult patients. Fewer procedure-related complications have been reported than for conventional methods using the internal jugular, femoral, or subclavian veins for access. On the other hand, thrombosis and phlebitis are more common than in conventional methods, and sometimes the catheter cannot be removed by manual traction. In this study, a 13-year-old girl had received long-term sedation from a PICC due to neurodegenerative disease. The patient was referred to our department because of difficulty in manual drawing for removal of the PICC. A CT scan showed that the PICC was bent at the right axillary vein and there was a high-density area around it. Surgical treatment was chosen after a joint conference between the department of pediatrics and us to discuss the reliability and invasiveness of the several treatments. Under general anesthesia, an incision was made under the right subclavian bone, and her axillary vein was exposed. The lumen of the vein was filled with a white plaster-like compound, and the catheter itself was buried inside it. The compound was removed, and the bent PICC was straightened and removed from the puncture site. There is no other case for difficult removal of PICC in this form without calcification. We believe that surgical removal was effective in this case because of her vascular structure.

Intravascular foreign bodies (IFB), most being iatrogenic foreign bodies, have become common clinical problems because of their adverse effect such as thrombogenesis, which may affect the function of important organs and even lead to death in some serious cases. It is necessary to remove IFB out in time. Percutaneous vascular intervention technologies have been widely used to remove IFB in recent years. The advancements of percutaneous vascular intervention technologies in application of removal IFB were reviewed in this article.

Objetivo - Relatar a experiência do Setor de Hemodinâmica do Hospital Säo Paulo (Escola Paulista de Medicina) na retirada percutânea de corpos estranhos intravasculares, analisando as principais técnicas utilizadas. Métodos - No período de 1985 a 1991, 15(0,18//) dos 7.936 procedimentos em nosso serviço relacionaram-se a corpos estranhos intravasulares em dez homens e cinco mulheres. Foram encontrados fragmentos de "intracath" em 9 pacientes (60//) cateteres diagnósticos em quatro (26,8//). Um paciente (6,6//) apresentava um cateter de Swan-Ganz com nó verdadeiro em veia cava superior e outro, um fragmento de fio guia retido no ramo circunflexo da artéria coronária esquerda durante a angioplastia transluminal coronária. Para a retirada dos corpos estranhos intravasculares foram utilizadas a técnica do laço por meio de cateter improvisado em 11 casos, o biótomo endomiocárdio em um caso e uma modificaçäo da técnica do laço para a retirada de fragmento intracoronário. Em dois casos de fragmentos periféricos, optou-se pela conduta expectante. Resultados - Obtivemos um sucesso de 100// nos 13 procedimentos de retirada de corpos estranhos intravasculares. Nos dois casos onde a conduta foi expectante näo ocorreram complicaçöes no seguimento clínico. Conclusäo - A técnica percutânea, principalmente a do laço, pela sua facilidade de execuçäo, alta eficácia, baixo custo e baixa incidência de complicaçöes deve ser o método de escolha para a retirada de corpos estranhos intravasculares. Devido ao inadequado seguimento na literatura, a melhor conduta nos casos periféricos ainda näo está bem estabelecida

Purpose - To report our experience on percutaneos vascular foreigh body retrievel and to analyse current techniques employed. Methods - From 1985 to 1991, 15 (0.18%) of 7.963 procedures performed in the Cardiac Catheterization Laboratory - Hospital São Paulo were intravascular foreign body retrieval: 9 (60%) intracath, 4 (26.8%) diagnostic catheters, one Swan Ganz catheter entrapped at superior cava vein and one fragment of angioplasty guide-wire in the circunflex branch of the left coronary artery. The snare technique was used in 11 cases, a endomyocardial bioptome device in 1 case and modified snare technique for the intracoronary wire fragment retrieval was used in 1 case. In two cases of embolized fragment in peripheral arteries, no attempt was done for retrieval. Results - All (100%) of the 13 attempted procedures were sucessfull. The two foreign bodies not removed had an uneventfull follow-up. Conclusion - The snare technique for percutaneous retrieval of intravascular foreign bodies is sofe and has excellent results. The management peripheral fragments is not well defined yet
