Subcutaneous Port Malfunction: A Retrospective Comparison Between Internal Jugular and Subclavian Vein Access

Abstract Purpose To evaluate malfunction rates of subcutaneous chest ports placed via the internal jugular and subclavian veins. Analysis and preventive measures to reduce the risk of complication between the 2 sites of venous access will be discussed. Methodology Retrospective review of 114 patients with malfunctioning subcutaneous port-a-catheters was performed. Of those 114 patients, 77 had venous access via a subclavian approach, whereas the remaining 37 had internal jugular vein access. Port insertion placement was evaluated and analysis of the malfunction rate was performed. Results There were 36 patients with 38 subcutaneous port malfunctions from internal jugular vein access. Thirty-four of 38 complications (89%) were not related to insertion and 4 out of 38 (11%) were related to vascular access approach. Seventy-seven patients with malfunctioning subcutaneous ports placed via the subclavian vein had a total of 127 complications. Twenty-eight of 127 complications (22%) were not related to insertion and 99 out of 127 (78%) of the complications were directly related to venous access approach. Conclusions Subcutaneous port placement complications can be avoided by measuring the length of the port catheter under fluoroscopic guidance and positioning the tip within 2 cm of the cavoatrial junction. Also, the jugular vein should be the first site for access unless patient circumstances do not permit this approach.
