Our medical approach

Bypass Graft Surveillance

A bypass graft surveillance ultrasound is a safe, non-invasive examination used to evaluate a vascular bypass graft and the blood flow through the arteries supplying it. A bypass graft is created to redirect blood around a severely narrowed or blocked artery, helping restore circulation to the affected limb.

Over time, a bypass graft or the arteries connected to it may develop narrowing (stenosis), reduced blood flow, or blockage. Duplex ultrasound allows your healthcare provider to monitor the graft and identify changes sometimes before noticeable symptoms develop.

Key Benefits

Limb & Graft Preservation

Identifies failing grafts early so corrective intervention can prevent complete thrombosis.

Completely Non-Invasive

Evaluates graft hemodynamics without needles, arterial puncture, or contrast dye.

Bedside Convenience

Enables post-operative patients to receive critical vascular follow-ups without difficult clinic travel.

Clinical Indications & Who Needs This Test

Regular surveillance can help:

  • Detect narrowing or blockage within or near the graft
  • Evaluate blood flow through the graft
  • Identify problems that may place the graft at risk of failure
  • Guide treatment or additional follow-up when necessary
  • Help maintain circulation and reduce the risk of serious complications

The examination is painless, uses no radiation, and requires no needles. A technologist gently
moves an ultrasound probe along the course of the bypass graft while obtaining images and
blood-flow measurements.

The Mobile Scanning Process

What to Expect During the On-Site Procedure

History & Preparation

The technologist reviews previous surgical reports to determine graft type (autogenous vein vs. synthetic), insertion points (proximal and distal anastomoses), and past baseline velocities.

Comprehensive Duplex Scan

Using warm acoustical gel, our technologist scans the inflow native artery, the proximal anastomosis, the entire length of the graft body, the distal anastomosis, and the outflow vessel.

Hemodynamic Evaluation

Color Doppler and Spectral Doppler velocities are measured to calculate Peak Systolic Velocity (PSV) ratios, identifying localized stenosis or low-flow states.

Duration

The bedside evaluation typically takes 45 to 60 minutes.

Empowering Brands
