Abstract
Our goal was to investigate the feasibility of inserting long-term central venous access devices in outpatients using a simple technique that minimizes the risks of complications linked to venipuncture and errors in management. We placed 147 central venous catheters (CVCs) in 134 patients under local anesthesia. No sedation was used, and all procedures were done in our radiology department. Of the 134 patients, 101 patients were included in the follow-up. Overall follow-up of patients was 24,596 catheter days (mean, 243.52 days). Percutaneous access, mostly by the subclavian vein, was done by micropuncture technique under fluoroscopic guidance. Six CVCs were untunneled, 36 were connected to totally subcutaneous ports, and 105 were tunneled. The only immediate complication was pneumothorax (3%). Late complications, expressed per 1000 catheter days, included CVC breakage (0.12), vascular thrombosis (0.08), catheter occlusion (0.04), dislodgment (0.24), and local or systemic infections (0.40). Outpatient CVC placement is feasible because the procedure is not adversely affected when the patient is not hospitalized. The drawbacks are identical to those faced by inpatients. Improved materials and more extensive information on the management of patients with long-term CVCs would help reduce complications further.
