Transjugular intrahepatic portosystemic shunt (TIPS) is a well-validated decompressive therapy option to manage ascites and variceal bleeding secondary to portal hypertension. Complications following TIPS procedures include hepatic encephalopathy, liver failure, and TIPS dysfunction. TIPS dysfunction is due to occlusion or stenosis of the TIPS shunt and can be caused by acute or chronic thrombosis. TIPS thrombosis is often treated with mechanical thrombectomy or catheter-directed thrombolytic therapy. Most cases of in-stent occlusion can be treated via a transjugular approach with recanalization or placement of additional stents. We present a case of a 72-year-old female who presented with worsening ascites 17 months after initial TIPS procedure; she was found to have a large thrombus completely occluding the TIPS stent. In our case, a combined transhepatic and transjugular approach was required for TIPS revision given the extent of well-organized clot located near the hepatic venous end of the stent, resulting from prolonged stent occlusion. This was an extremely challenging scenario with two overlapping covered stents and a bare metal stent at the hepatic venous end in the setting of chronic thrombosis and a well-organized fibrous cap. The case highlights the need for optimal initial placement of the primary TIPS shunt to avoid the need for subsequent complex interventions to maintain TIPS shunt patency.
经颈静脉肝内门体分流术(TIPS)是一种经过充分验证的减压治疗方法,用于治疗门静脉高压继发的腹水和静脉曲张出血。TIPS手术后的并发症包括肝性脑病、肝功能衰竭和TIPS功能障碍。TIPS功能障碍是由于TIPS分流道闭塞或狭窄所致,可由急性或慢性血栓形成引起。TIPS血栓形成通常采用机械性血栓切除术或导管定向溶栓治疗。大多数支架内闭塞病例可通过经颈静脉途径进行再通或放置额外支架来治疗。我们报告一例72岁女性患者,在初次TIPS手术后17个月出现腹水加重;发现其有一个大血栓完全阻塞了TIPS支架。在我们的病例中,由于支架长期闭塞,位于支架肝静脉端的机化血栓范围较大,因此TIPS翻修需要采用经肝和经颈联合入路。这是一个极具挑战性的情况,在慢性血栓形成和有一个机化纤维帽的背景下,肝静脉端有两个重叠的覆膜支架和一个裸金属支架。该病例强调了初次TIPS分流道最佳初始放置的必要性,以避免后续为维持TIPS分流道通畅而进行复杂干预的需要。
