Question:
Which of the following synthetic material is not used for vascular and cardiac surgeries?
Which of the following synthetic material is not used for vascular and cardiac surgeries?
Show Hint
Dacron, PTFE, and Polypropylene are the big three materials in cardiovascular surgery.
Dacron is used for major vessel grafts, PTFE for smaller grafts and sutures, and Polypropylene is the classic monofilament suture for anastomoses.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Vascular and cardiac surgeries require biomaterials with exceptional biocompatibility, high tensile strength, minimal thrombogenicity, and long-term structural integrity when implanted in the body.
Step 2: Detailed Explanation:
Let us review the medical and surgical applications of the listed synthetic polymers:
1. Polypropylene (Prolene): This is an extremely popular non-absorbable monofilament suture material used extensively in vascular and cardiac surgeries. It possesses high tensile strength, causes minimal tissue reaction, and has a smooth surface that prevents drag through delicate vessel walls.
2. Polytetrafluoroethylene (PTFE Teflon Gore-Tex): Expanded PTFE (ePTFE) is widely used to manufacture synthetic vascular grafts, cardiac patches, and sutures. It is highly inert and promotes tissue ingrowth.
3. Dacron (Polyethylene terephthalate Polyester): This braided polyester is the gold standard material for large-diameter vascular grafts, cardiac patches, and the sewing rings of prosthetic heart valves.
4. Polyoxymethylene (POM Acetal Delrin): This is a rigid, highly crystalline engineering thermoplastic used primarily for mechanical gears and external medical devices. It is not used as an implantable material for vascular anastomoses or cardiac patches due to its rigid mechanical properties and lack of suitable tissue integration.
Step 3: Final Answer:
Therefore, Polyoxymethylene is the synthetic material not used for vascular and cardiac surgeries.
