Which material is commonly used for a bypass graft and would appear as woven material on ultrasound?

• A. Dacron (polyester) woven material
• B. Stainless steel mesh
• C. Gore-Tex graft
• D. Silicone tubing

Answer: (A)

Dacron (polyester) woven grafts are the material commonly used for bypass grafts that would appear as a woven pattern on ultrasound. The fabric-like interlacing of polyester fibers creates a woven echotexture within the graft wall, which ultrasound can depict as a braided or fabric-like pattern. Gore-Tex (ePTFE) grafts, by contrast, are smooth and not woven, so they don’t show that woven pattern. Stainless steel mesh isn’t used as a typical vascular bypass graft, and silicone tubing isn’t used as a durable long-term vascular graft in humans.
