Shunt thrombosis is a relatively frequent complication of implant grafts but less common in native fistulas; both may undergo mechanical recanalization without thrombolysis. While in native fistulas, simple balloon angioplasty is a very useful tool for short-segment thrombosis, extensive thrombosis in native veins or grafts requires use of different mechanical devices or aspiration catheters. In venous access thrombosis, thrombolysis or fibrinous sheath stripping are percutaneous options.
分流血栓形成是植入移植物相对常见的并发症，但在自体动静脉内瘘中较少见；两者均可在不进行溶栓的情况下实现机械再通。对于自体动静脉内瘘，单纯球囊血管成形术是治疗短节段血栓形成的非常有用的工具，但自体静脉或移植物的广泛血栓形成则需要使用不同的机械设备或抽吸导管。在静脉通路血栓形成中，溶栓或剥脱纤维蛋白鞘是经皮治疗的选择。
