RESUMO
Percutaneous transhepatic biliary drainage is a well-established technique for the treatment of biliary obstruction in patients with failed endoscopic approaches. We report on an 82-year-old man with a history of cholangiocarcinoma treated with pancreaticoduodenectomy who presented with recurrent cholangitis and sepsis. Percutaneous transhepatic biliary drainage was performed after unsuccessful endoscopic retrograde cholangiography, which initially improved his condition. However, due to an accidental dislodgement, there was an intra-abdominal fracture of the drain which led to biliary peritonitis and clinical deterioration. The fractured intrahepatic drain was successfully extracted in our angio suite, and a novel subcutaneous fixation technique was introduced to prevent similar occurrences in the future. This case study signifies the role of interventional radiology in the management of percutaneous transhepatic biliary drainage complications and the importance of preventative measures to avoid dislodgement.
RESUMO
Choledocholithiasis, characterized by the presence of stones in the common bile duct, poses significant challenges in clinical management, particularly when the stones are massive. While endoscopic methods are often effective in stone removal, complications such as the impaction of foreign bodies like Dormia baskets can occur. These complications may necessitate alternative approaches, including surgical intervention, highlighting the importance of exploring innovative interventional techniques. We report on an 89-year-old patient presenting with massive choledocholithiasis, involving complete filling of the intra- and extrahepatic bile duct system with large stones up to a maximum of 2 cm. The patient underwent interventional removal of a Dormia basket (3.5Fr. Boston Scientific, USA) impacted in the common bile duct. This procedure proved challenging due to the metallic end marker of the basket perforating through the wall of the distal common bile duct, rendering it fixed. Given the complexity of the case, a parallel approach combining percutaneous transhepatic cholangiography and drainage with simultaneous endoscopy was employed to successfully extract the fixed Dormia basket. In cases of severe choledocholithiasis complicated by the impaction of foreign bodies such as Dormia baskets, innovative interventional strategies are crucial for successful management. Our case highlights the effectiveness of a parallel approach involving percutaneous transhepatic cholangiography and drainage alongside simultaneous endoscopy in safely removing the fixed foreign body from the common bile duct. This multidisciplinary approach not only offers a viable alternative to surgical intervention but also underscores the importance of collaboration between interventional radiologists and endoscopists in optimizing patient outcomes in complex biliary interventions.
RESUMO
The initial treatment of acute and subacute portal vein thrombosis, which is the most common cause of portal vein occlusion, consists of intravenous anticoagulation with heparin, but there is still a huge uncertainty among physicians regarding the role of more invasive therapies. We report a 61-year-old male patient, who presented in our emergency room with a subacute complete thrombosis of the intra- and extrahepatic portal vein, mesenteric vein, with associated venous congestion of 20-30 cm length of the small intestine with a quick and complete remission of the portal vein thrombosis under sole i.v. heparin-perfusor therapy without any complications. Molecular genetic analysis found combined genetic mutations of the gene factor 2 (c.20210G>A, heterozygotic), SERPINE1 (-675 5G>4G, heterozygotic), and the MTHFR gene. Along with this interesting case, we also present the recent status of portal vein thrombosis and portal vein occlusion in the literature.
