stent graft
Combination device with metal framework covered by fabric material used to exclude aneurysms or repair vessel injuries.
Full Definition
A stent graft is a sophisticated endovascular device combining a metallic stent framework with a fabric graft covering, designed to provide structural support while excluding blood flow from aneurysms or sealing vessel injuries. These devices are deployed through minimally invasive techniques and are commonly used in treating aortic aneurysms, traumatic vessel injuries, and complex arterial lesions. In vascular medicine documentation, stent graft specifications including diameter, length, fabric material, and deployment characteristics must be precisely recorded, as device selection and positioning directly impact patient outcomes and long-term surveillance requirements.
Usage
Usage note: Distinguish from uncovered stents; specify fabric material (PTFE, polyester) when clinically relevant.
