Application Of Ultrasound-Guided Endocavity Technique In Hemodialysis Access

Ultrasound guided PTA treatment does not require special radiological equipment and can be completed in an ultrasound room or an ordinary operating room, with low cost.

Ultrasound has important advantages in preoperative diagnosis of hemodialysis access, intraoperative positioning, and postoperative follow-up. It is a necessary skill for vascular access physicians. Ultrasound-guided endocavity technology does not require special equipment and can be performed at the bedside (POCUS). It is suitable for the characteristics of fast processing of internal fistula complications, while avoiding the application of contrast agents. It has the advantages of real-time display, multi-angle imaging, and low cost. It is safe in clinical practice. It is effective and can be applied to the treatment of puncture approach, stenosis or occlusive disease and pseudoaneurysm. Unique advantages are on ultrasound-guided endocavity technology and conventional radiological-guided endocavity technology. Digital subtraction and angiography pay more attention to the whole, and ultrasound is better in details. It needs to be rationally applied for any kind of methods.
