Development of blood access using new materials

Conclusion

Thrombosis, narrowing, obstruction, infection, pseudoaneurysm formation, arterial steal syndrome, venous hypertension, and congestive heart failure are common complications in HD patients with primary or autogenous AV fistulas, prosthetic graft AV shunts, or permanent catheters.

The most important problem is that we still do not have enough suitable prosthetic graft for the AV shunt. Historically. The AV shunt was developed for use in cardiovascular diseases. The used for frequent puncture and the risk of infection were not anticipated. We hope to develop a suitable prosthetic graft for the AV shunt. Next, the development of interventional radioangioplasty will help HD patients. Last, the no-needle approach, like the external catheter, should be considered more for the treatment of HD patients.
