Pre- and Post- Graft Monitoring Scan

Replacing, or grafting of arteries is a surgical treatment for arterial disease. Grafts need to be monitored to identify any potential failures as a result of narrowing (stenosis).

Information for doctors
Patients with infrainguinal bypass grafts should have routine duplex scanning at six weeks, three weeks and six months and then six monthly to identify the development of graft stenoses predisposing to thrombus and occulsion. Stenoses occur in approximately 25% of grafts at two years. Identification of the problem with prompt balloon dilation or surgical intervention can prevent graft occlusion and limb loss.

Indications
- The presence of a functioning infrainguinal bypass graft.
