Chest X-ray method to choose catheter length for implantable venous ports
Accuracy and Clinical Applicability of a Chest X-Ray-Based External Measurement Method for Optimal Catheter Tip Positioning in Totally Implantable Venous Access Port Placement
This tests whether measurements from a recent chest X-ray can help pick the correct catheter length for adults getting a totally implantable venous access port.

What this trial studies
Adults scheduled for elective totally implantable venous access port (TIVAP) placement who have a recent posterior–anterior chest X-ray will have anatomical landmarks measured on that film to calculate the expected catheter length. The calculated length will be used during port placement, and catheter tip position will be confirmed with the center's usual imaging method after placement. The approach aims to provide a simple, equipment-light way to estimate catheter length without routine intraoperative fluoroscopy or echocardiography. Patients with distorted chest anatomy, known central venous obstruction, or unclear X-rays are excluded.
Who should consider this trial
Good fit: Adults aged 18 or older scheduled for elective TIVAP placement who have a clear posterior–anterior chest X‑ray from the past three months and can provide informed consent.
Not a fit: Patients with known central venous stenosis or occlusion, congenital heart disease, significant mediastinal distortion, unclear chest X‑ray landmarks, emergency implantation, pregnancy per local policy, or inability to consent are unlikely to benefit from this method.
Why it matters
Potential benefit: If successful, this could shorten procedures, reduce the need for extra imaging, and lower risks from catheter malposition such as thrombosis or arrhythmia.
How similar studies have performed: Landmark-based X‑ray methods for estimating catheter length have been described and used in practice, but published evidence is limited and results have been variable.
