AI Article Synopsis
- Pediatric hemato-oncologic patients often need central catheters for chemotherapy, with the cavoatrial junction being the preferred insertion site, but existing identification methods lack standardization.
- A study involving 15 oncology patients utilized augmented reality to create 3D models for precise catheter placement and confirmed the positioning with portable x-rays.
- Results showed that the augmented reality method significantly reduced the average distance from the cavoatrial junction compared to traditional techniques, indicating it is a safer and more accurate approach without extra costs.
Article Abstract
Background: Pediatric hemato-oncologic patients require central catheters for chemotherapy, and the junction of the superior vena cava and right atrium is considered the ideal location for catheter tips. Skin landmarks or fluoroscopic supports have been applied to identify the cavoatrial junction; however, none has been recognized as the gold standard. Therefore, we aim to develop a safe and accurate technique using augmented reality technology for the location of the cavoatrial junction in pediatric hemato-oncologic patients.
Methods: Fifteen oncology patients who underwent chest computed tomography were enrolled for Hickman catheter or chemoport insertion. With the aid of augmented reality technology, three-dimensional models of the internal jugular veins, external jugular veins, subclavian veins, superior vena cava, and right atrium were constructed. On inserting the central vein catheters, the cavoatrial junction identified using the three-dimensional models were marked on the body surface, the tip was positioned at the corresponding location, and the actual insertion location was confirmed using a portable x-ray machine. The proposed method was evaluated by comparing the distance from the cavoatrial junction to the augmented reality location with that to the conventional location on x-ray.
Results: The mean distance between the cavoatrial junction and augmented reality location on x-ray was 1.2 cm, which was significantly shorter than that between the cavoatrial junction and conventional location (1.9 cm; P = 0.027).
Conclusions: Central catheter insertion using augmented reality technology is more safe and accurate than that using conventional methods and can be performed at no additional cost in oncology patients.

Background: Children who need to have major surgery or are critically ill often require the insertion of a central venous catheter (CVC). To avoid serious complications, it is important to correctly position the CVC tip at the junction of the distal superior vena cava and the right atrium (cavoatrial junction). Transthoracic echocardiography (TTE) can be used to confirm the correct position of the CVC tip.

Objectives: The assessment of correct positioning of central venous catheters (CVC) is of major concern to avoid complications.Vascular access associations have established the cavo-atrial junction (CAJ) as the most appropriate CVC tip location. Among the different chest X-ray (CXR) landmarks proposed for assessing tip position relative to the CAJ, only the pericardial reflection lies in the same plane as the vascular structures assessed.

Article Synopsis
- - A 61-year-old man with end-stage renal disease and a tunneled dialysis catheter presented for hypoxia after a recent hospital discharge for a neck abscess.
- - Initial ultrasound upon admission showed a pericardial effusion without significant tamponade, but new hypotension developed during his stay, indicating worsening condition.
- - Urgent pericardiocentesis was performed, draining a large volume of fluid, and interventional radiology suspected an endovascular injury as the cause of the hemopericardium related to catheter placement.
