Impact of central venous port implantation method and access choice on outcomes

Figure 1 Rupture of a catheter implanted through the right subclavian vein. A: Fluoroscopy revealed contrast extravasation (red arrow) in patient 1; B: In patient 1, at the ex situ evaluation of the catheter, we found an approximately 2 cm linear breakage. This breakage was 9 cm distal to the port-catheter attachment point; C: In patient 2, radiological evaluation revealed a complete breakage, and the distal end of the catheter was found to be free floating in the atrium (red arrow); D: The port site was between the clavicle and the first rib (red arrow) in patient 2. The interventional radiology team removed the broken distal end through an angiographic intervention.

Figure 2 Upturned port. We could not puncture the port, and radiological investigation revealed that the posterior, broad-based part of the port had turned down (red arrow).
