There is no established treatment for bleeding bile duct varices (BDVs). We report the first case of portal vein (PV) stenting completely eradicating bleeding BDVs. A 70-year-old male with malignant lymphoma developed BDVs due to PV obstruction, which had caused compression and stricture of the distal bile duct. Endoscopic retrograde cholangiography was performed to evaluate the stricture and bleeding from the ruptured BDV was observed. Endoscopic hemostasis was difficult, requiring reopening of the extra-hepatic PV and reducing the blood flow to the BDVs for hemostasis. Therefore, PV stenting was performed. During the procedure, portal angiography confirmed an inflow tract to the BDVs. Therefore, covered stents were placed in the PV and adjusted to block the inflow tract to the BDVs at the distal end. After stenting, the BDVs were successfully blocked and all PV blood flowed through the stent placed in the extra-hepatic PV. Two weeks after stenting, the BDVs had disappeared completely and the bleeding has not recurred for months. We experienced a case in which PV stenting not only reopened an obstructed PV but also successfully occluded the inflow tract. This case demonstrates the potential of PV stenting for the treatment of hemorrhagic BDVs.
对于胆管静脉曲张(BDV)出血,目前尚无既定的治疗方法。我们报告了首例完全消除出血性 BDV 的门静脉(PV)支架置入术。一名 70 岁男性患有恶性淋巴瘤,由于 PV 阻塞导致 BDV,这导致了远端胆管的压迫和狭窄。进行了经内镜逆行胰胆管造影术(ERCP)以评估狭窄程度,并观察到破裂的 BDV 的出血。内镜止血困难,需要重新打开肝外 PV 并减少流向 BDV 的血流以止血。因此,进行了 PV 支架置入术。在该过程中,门静脉血管造影术确认了 BDV 的流入通道。因此,将覆膜支架放置在 PV 中,并调整其位置以阻塞 BDV 的远端流入通道。支架置入后,BDV 成功被阻塞,所有 PV 血液均通过放置在肝外 PV 的支架流动。支架置入后 2 周,BDV 完全消失,并且数月来未再次发生出血。我们经历了一个病例,其中 PV 支架置入术不仅重新开放了阻塞的 PV,而且还成功地闭塞了流入通道。该病例表明,PV 支架置入术治疗出血性 BDV 具有潜力。
