Quality assessment with ultrasonic imaging and blood flow measurement during different vascular surgery procedures protects the patient from serious side effects and minimizes the risk for re-interventions.
Graft patency is the predominant predictor of long-term survival after vascular surgery.
The primary aim of TTFM is to obtain information on the immediate results of the reconstruction, where a technical failure may jeopardize an otherwise successful operation.
In carotid endarterectomy (CEA), the risk of restenosis and embolization is increased if technical imperfections during the initial operation remain undetected.
In AV Access surgery a non-maturing fistula due to low blood flow can require reintervention and prolonged use of a central dialysis catheter; if the flow is too high, there is a risk of hand ischemia and heart failure.
