Abstract: | Purpose: To evaluate the safety and feasibility of a percutaneous Port-Catheter System (PCS) implanted via the subclavian artery (SCA)
for regional chemotherapy or chemoembolization of thoracic, abdominal, and pelvic malignant tumors.
Methods: Percutaneous puncture of the SCA was performed in 256 patients with thoracic, abdominal, or pelvic malignant tumors; then
a catheter was inserted into the target artery. After the first transcatheter chemotherapy or chemoembolization with an emulsion
of lipiodol and anticancer agents, an indwelling catheter was introduced with its tip placed in the target artery and its
end subcutaneously connected to a port.
Results: The procedure was successfully completed in all 256 cases (100%). The indwelling catheter tip was satisfactorily placed in
the target arteries in 242 cases (98%). Complications attributable to the procedure occurred in 20 (7.8%) cases, including
pneumothorax (n = 10, 4%), hemothorax (n = 1, 0.4%), infections in the pocket (n = 4, 1.6%), and hematoma at the puncture site (n = 5, 2%). There were no severe sequelae or deaths. The duration of PCS usage was 1–36 months (median 9.5 months). During the course
of treatment, occlusion of the target artery occurred in 20 cases (7.8%). Dislocation of the tip of the indwelling catheter
occurred in 12 cases (4.7%); in 10 of the 12, the tip of the indwelling catheter was repositioned into the target artery.
In all 10 cases no large symptomatic hematomas developed after the PCS was removed.
Conclusion: Percutaneous PCS implantation via the left SCA, a relatively new procedure, is a safe and less invasive treatment approach
than surgical placement for malignancies. |
