SUMMARY~~~~~i~~~~~ with intracardiac catheter embolus in 6 patients over a &year period is reported, and a brief review of the literature made.Thi:j communication reports our experience with catheter embolus in 6 patients, in 2 of whom there was bacterial endocarditis. In each case successful remov.al was carried out.
CASE REPORTSF~~~~~ bodies which reach the interior of the humanIn 5 children, portions of a ventriculo-atrial (Spitzbecome detached. Their ages ranged from 18 months to investigation or treatment. Catheter embolus was yearri, and the average length of time the tubing had first described in a n experimental animal by Tuell, been known be detached was months in of the Martin, and Laufman in 1948, and since that time a children. In the remaining child it had been known to be number of reports have been made. free for 7 years. All catheters were radio-opaque, and heart during peacetime are almost always a result of Holter:l shunt inserted because of hydrocephalus had were located preoperatively by plain radiography. In only I patient of these 5 was there clear evidence of endocarditis with repeated blood-cultures of Aerobacter aerogenes.In each of these children removal was advised and this was carried out under hypothermia with inflow occlusion. In thi:i procedure the anaesthetized child was cooled by surface cooling to 33" C. with drift to 30-3 I ' C. The heart was exposed by midline sternotomy and after taping the vena cavae, inflow occlusion was established and the foreign body removed. One catheter was in the right atrium, 3 in the right ventricle, and 2 in the pulmonary artery. Periods of inflow occlusion varied from I min. 20 sec to 4min. Rewarming was by surface heating and the postoperative condition was satisfactory in all. In the child where Aerobacter infection had been established., this disauueared following the removal of the catheter and did nit recur, althougTh the child died 3 years later from the effects of hydrocephalus.
