RESUMEN
PURPOSE: To evaluate the single-incision technique for the placement of subcutaneous chest ports. Advantages, technical success, and complications were assessed. MATERIALS AND METHODS: From March 2007 through May 2008, 161 consecutive chest ports were placed with a modified single-incision technique and sonographic and fluoroscopic guidance via the right internal jugular vein (IJV; n = 130), right external jugular vein (n = 1), right subclavian vein (n = 1), or left IJV (n = 28). The primary indication was for long-term chemotherapy; all patients had malignancy. RESULTS: All single-incision chest port insertions were technically successful. Ports were placed in patients 19 months to 93 years of age (mean, 56.3 y), with a mean follow-up of 203.6 device-days per patient and a total of 32,779 catheter access days. No procedure-related complications, pocket hematomas, venous thromboses, or pneumothoraces were observed. Minor delayed complications occurred in three patients. Premature catheter removal was required for two patients (1.2%; 0.006 per 100 catheter-days). One port was removed less than 30 days after implantation for infection of the pocket (0.61%; 0.003 per 100 catheter-days). Another catheter was removed because of patient dissatisfaction and unconfirmed concerns with arrhythmia (0.61%; 0.003 per 100 catheter-days). One minor superficial wound infection was successfully treated with oral antibiotics, with the port kept in place. CONCLUSIONS: Use of a single-incision technique for chest port implantation in adult and pediatric oncology patients is feasible. This may be the preferred method of subcutaneous port placement, as it has a very low complication rate and a high success rate. Prospective evaluation is needed to compare it versus the conventional two-incision technique.
