|July 1, 1980
Insights
Radiology effectively identifies vascular issues like inflow or outflow obstruction and false aneurysms in arteriovenous grafts used for haemodialysis. This study details the imaging techniques for diagnosing these specific complications.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Haemodialysis requires reliable vascular access.
- Arteriovenous grafts are one type of haemodialysis access device.
- Vascular complications can compromise graft function.
Purpose of the Study:
- To evaluate the role of radiology in identifying local vascular complications of haemodialysis access devices.
- To classify and illustrate common local complications associated with arteriovenous grafts.
- To describe an effective angiographic technique for diagnosing these complications.
Main Methods:
- Review of radiological findings in patients with haemodialysis access.
- Classification of local vascular complications: inflow obstruction, false aneurysm, outflow obstruction.
- Description of a rational angiographic technique for assessment.
Main Results:
- Radiology is valuable for demonstrating local vascular complications specifically in arteriovenous grafts.
- Common complications identified include inflow obstruction, false aneurysm, and outflow obstruction.
- The described angiographic technique aids in visualizing these issues.
Conclusions:
- Radiological imaging, particularly angiography, is crucial for diagnosing local vascular complications in arteriovenous grafts.
- Understanding these complications and employing appropriate imaging techniques is essential for managing haemodialysis access.
Abstract:
Of the three types of haemodialysis access devices, radiology is of value in demonstrating local vascular complications only in the arteriovenous graft. The local complications are classified as inflow obstruction, false aneurysm and outflow obstruction. A rational angiographic technique is described and the local complications likely to be encountered are illustrated.
