Successful Percutaneous Retrieval of Embolised Septal Occluder Device and Device Closure of Atrial Septal Defect in Combined Procedure

Transcatheter device closure is the treatment of choice in patients with secundum atrial septal defects with adequate rims. It is technically safe, feasible and has the obvious advantage of being a nonsurgical technique. Patient is free from the scar especially young, unmarried females. It is not free of complications. Device embolization and arrhythmias are the major complications. Embolised device can cause hemodynamic compromise by obstructing the blood flow if it gets embolised in pulmonary artery. We report a case of 24 year old female, taken for device closure of atrial septal defect. Device gets embolised in pulmonary artery causing hemodynamic compromise by causing obstruction to blood flow. This embolised device was successfully retrieved percutaneously. The atrial septal defect was closed with one size larger device, in the same sitting. Patient is asymptomatic and is free from any scar.

Retirada percutânea de corpos estranhos intravasculares / Percutaneous retrieval of intravascular foreign bodies

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
