The use of port central venous catheters (CVCs) for chemotherapeutical use has seen exponential growth over the last decades. However, port CVC misplacement may lead to catheter malfunction (such as partial or total catheter blockade), which might be complicated by thrombosis and catheter superinfections, and these in turn may lead to pulmonary embolism and bloodstream infections. The overall occurrence of port CVC misplacement is up to 6%; nonetheless, port CVC misplacement may occur in up to 67% of patients with early CVC dysfunction (occurring within three months of catheter insertion). Thereafter, the prompt evaluation of catheter position among patients with first-trimester CVC dysfunction is extremely important. The aim of the present manuscript is to support medical oncologists, haematologists, and clinicians in timely suspicion and recognition of port CVC misplacement among patients with early CVC dysfunction. Radiological educational iconographic materials that will assist a prompt estimate of port-CVC dislocation are provided.
