The indications for insertion of semipermanent right atrial silicone catheters and immediate and long-term complications in patients admitted to a gynecologic oncology service, are described. Eight-five catheters were inserted in 79 patients for a variety of indications. Most catheters were placed under local anesthesia, in the patient's hospital room. Immediate morbidity caused by damage to the pleura was limited to three patients (3.5%). Infectious morbidity related to catheter use was seen in five patients (5.9%). Two patients were unable to administer daily heparin boluses through the catheter, and in both of these patients catheter thrombosis was seen (2.4%). A right atrial catheter can easily be inserted at the patient's bedside or in an outpatient setting. This device should be offered to any patient in whom intermediate or long-term vascular access is desired for nutritional support, chemotherapy, pain control, or similar indications.
