Chest Port Placement in Freestanding Outpatient Vascular Access Centers

Background Ports have traditionally been inserted in hospitalized inpatients; however, there has been an increasing transition to outpatient placement by interventionalists in hospital imaging suites. To our knowledge, port implantation in nonhospital settings has not been reported in peer-reviewed literature. Here, we report our experience with port placement in freestanding outpatient vascular centers. Methodology The electronic medical record for 47 centers was retrospectively searched to identify port placements between January 1, 2012, and December 31, 2018. Data included indications, platelet inhibitor/anticoagulants, American Society of Anesthesiologists (ASA) classification, port type, site, tip position, peri-procedure medications, procedure time, and pain scores. Complications were determined by phone calls at 48-72 hours. Results No short-term malfunctions were reported. In total, 5,890 ports were placed for chemotherapy (n = 5,531), IV therapy (n = 77), antibiotics (n = 74), hyperalimentation (n = 19), phlebotomy (n = 7), medications (n = 4), miscellaneous (n = 74), and unknown (n = 104). Regarding ASA classifications, 1% (n = 65) were categorized as Class I, 20% (n = 1,203) as Class II, 78% (n = 4,592) as Class III, and 0.5% (n = 30) as Class IV. Overall, 3,712 were single-lumen power ports, 341 dual-lumen, 19 unknown, 7 arm, 1 other, and 1,810 were unspecified. There were 5,855 chest, 19 arm, 1 thigh, and 15 unspecified ports. Tips were positioned in the superior vena cava (n = 1,582), superior vena cava-right atrium (n = 497), right atrium (n = 272), inferior vena cava (n = 2), inferior vena cava-right atrium (n = 1), or not specified (n = 3,536). The mean procedure time was 29 minutes (range = 6-137). The mean peak pain score was 0.86 (range = 0-10). Complications (n = 33) included 16 emergency/hospital admissions
