The increasing use of the indwelling venous catheters and cardiovascular catheters has led to many iatrogenic complications. One of the most serious complications is catheter embolization, caused by inadvertent fracture of a fragment of catheter remaining within cardiovascular systems. In the catheter embolization, there are serious consequence such as thromboembolism, sepsis, cardiac arrythmia and others. Fisher and Ferreyro (1978) reported a 71% incidence of serious morbidity or death following to intravacular foreign bodies in patients without removal. The authors experienced a case of retained central venous pressure monitoring catheter fragment extending from superior vena cava to hepatic segment of inferior vena caba. CVP catheter was introduced into right subclavian venous route for hyperalimentation, because of poor general condition for operation of afferent loop syndrome following to resecton of the gastric carcinoma with Billoth II operation. On attempting to remova of CVP catheter on recovery from afferent loop syndrome, a large portion of the CVP catheter was cut off into S.V.C. Percutaneous puncture of right femoral vein with Seldinger technique was done and 9F introducer sheath was indwelled. The hellical baket of Dotter intravascular retriever set was advanced through sheath was indwelled. The hellical basket of Dotter intravascular retriever set was advanced through the sheath upto retained CVP catheter, and it was grapsed. The retrieved CVP catheter fragment showed several tiny blood clots on surface. The patientwas uneventfully recovered, and was discharged asymptomatic on second day of the procedure.
