Direct right atrial catheter insertion with video-assisted thoracic surgery

Difficult Vascular Access in Children with Short Bowel Syndrome: What to Do Next?

Short Bowel Syndrome and intestinal failure are chronic and severe conditions that may require life-long parenteral nutrition in children. Survival of these children rely on the correct functioning of central venous catheters; therefore, careful management, prevention, and treatment of complications is of paramount importance. Despite a growing awareness of preserving the vascular real estate, a certain number of patients still experience a progressive and life-threatening exhaustion of vascular access. We searched the literature to highlight the current management of children with vascular exhaustion, specifically focusing on vascular access salvage strategies and last-resource alternative routes to central veins. Given the paucity of data, results are reported in the form of a narrative review.

Thoracoscopic-assisted central line placement for a thrombosed superior vena cava

BACKGROUND

In children who require prolonged and multiple venous catheterizations, the superior vena cava and iliofemoral veins may become occluded, making central venous access a difficult challenge. We report an innovative technique of catheter insertion percutaneously from the neck into the right atrium traversing a thrombosed superior vena cava using video-assisted thoracoscopic surgery.

METHODS

Two children with irreversible intestinal failure had 4 central venous accesses insertions using the above-mentioned technique. Both had occluded major central veins after multiple catheterizations. An interventional radiologist and cardiologist failed to establish a central venous access in both patients.

RESULTS

A 9-year-old boy has a long-term catheter functioning for 8 months, and in an 18-month-old girl, the line was removed accidentally 6 weeks from its insertion and 2 months later for a line leak. It was then reinserted each time using the same technique.

CONCLUSION

This technique of catheter placement into the right atrium using video-assisted thoracoscopic surgery when other conduits are unavailable can be lifesaving in children depending on total parenteral nutrition.

Thoracoscopic-assisted placement of azygos vein central venous catheter in a child

Loss of central venous access in intestinal failure patients is a potentially fatal complication, and an indication for intestinal transplantation. Thrombosis of the superior vena cava (SVC) has historically been considered a contraindication to small bowel transplantation; however, unconventional central venous access can facilitate survival and eventual transplant procedure in patients with end-stage central venous access. We describe a technique for azygos vein central catheter insertion utilizing thoracoscopic guidance in a 14-year-old girl with thrombosis of the SVC and chronic idiopathic pseudo-obstruction syndrome awaiting multivisceral transplantation. The technique is simplified by utilizing carbon dioxide (CO(2)) insufflation of the thoracic cavity to collapse the lung instead of double-lumen endotracheal tube placement, and no postoperative chest tube drainage of the pleural space is required. Thoracoscopic-assisted central access can also be used in children requiring chronic hemodialysis with limited venous sites due to thrombosis or small size of vessels.

Reoperative venous access

The maintenance of long-term venous access is critical to the livelihood of children in a variety of clinical situations, especially those who are dependent on parenteral nutrition. Whereas the traditional routes of either peripheral or central venous access are initially adequate, most of these sites eventually succumb to the pitfalls associated with long-term venous access. This review provides a comprehensive and multidisciplinary approach to the management of reoperative venous access with regard to preoperative planning and imaging and specific techniques in interventional radiology and surgery.

Home parenteral nutrition. 25 years later

After 25 years, there is enough clinical outcome experience to determine appropriate use of home parenteral nutrition in different disease states and age groups. Information regarding how to avoid complications and how patients and families can find necessary psychosocial support is provided in this article. Currently, small bowel transplantation is not a safer choice, unless there is severe liver disease caused by home parenteral nutrition or lack of central intervenous access.
