A stent-graft comprising a first stent-graft and a second stent-graft for a central vein is provided, in which the first stent-graft and the second stent-graft with the appropriate diameters can be selected depending on patient’s veins and overlappingly connected one to another. Therefore, the stent-graft for central veins of the present creation can improve the matching of the stent-graft with different patients, so that the surgical success rate is increased and the postoperative problems caused by the inappropriate diameters of stent-graft.本新型提供一種包含一第一支架及一第二支架的中心靜脈用覆膜支架，可依據各病患之靜脈選擇適當口徑之第一支架及第二支架並加以重疊套接組合。因此，本新型之中心靜脈用覆膜支架可提高支架與不同患者靜脈血管的匹配性，進而增加手術之成功率並減少術後因支架大小不適產生的問題。
