چکیده

In recent years, percutaneous endovascular intervention has become the primary treatment for pediatric post-liver transplantation portal vein stenosis. This procedure is usually performed using a transhepatic approach. Herein, we report the transsplenic endovascular management of a 3-year-old girl with post-liver transplantation, late-onset portal vein occlusion, which occurred after repeated percutaneous transhepatic angioplasty procedures. Transhepatic access was precluded by thrombosis, and we considered an ileocecal approach too invasive; therefore, we performed a portal vein recanalization by puncturing a collector branch of the splenic vein, dilating the portal vein thrombotic stenosis using a balloon, and inserting a self-expanding stent. The majority of percutaneous procedures for portal vein stenosis in children are transhepatic; however, our case demonstrates that transsplenic stent insertion is possible, and should be considered when the transhepatic approach is precluded.

Interventional Treatment for Portal Venous Occlusion After Liver Transplantation

Portal vein (PV) occlusion after liver transplant is an uncommon clinical situation, and percutaneous interventional treatment for this condition has not been widely described. The aim of this study was to evaluate the long-term treatment effect of interventional treatment for PV occlusion after liver transplantation (LT). Follow-up data of 13 patients who received interventional treatment for ...

Transsplenic portal vein reconstruction–transjugular intrahepatic portosystemic shunt in a patient with portal and splenic vein thrombosis

Portal vein thrombosis (PVT) is a potential complication of cirrhosis and can worsen outcomes after liver transplant (LT). Portal vein reconstruction-transjugular intrahepatic portosystemic shunt (PVR-TIPS) can restore flow through the portal vein (PV) and facilitate LT by avoiding complex vascular conduits. We present a case of transsplenic PVR-TIPS in the setting of complete PVT and splenic v...

Endovascular stent graft for traumatic splenic vein aneurysm via percutaneous transsplenic access

Traumatic splenic vein aneurysm (SVA) is an extremely rare entity. Traditionally, treatment varied from noninvasive followup to aneurysm excision with splenectomy. However, there has been no prior report of traumatic SVA treated with endovascular stent graft for SVA via percutaneous transsplenic access. Therefore, we report the case of a 56-year-old man successfully treated with endovascular st...

Y-configuration stent combined with iodine-125 seeds strand for the treatment of hepatocellular carcinoma with tumor thrombosis in portal vein branches

RATIONALE Currently, the treatment of hepatocellular carcinoma (HCC) associated with portal vein tumor thrombosis (PVTT) is a challenge. Percutaneous puncture endovascular placement of iodine-125 (I) seeds strand and stent is reported to treat HCC with tumor thrombus effectively. However, it is proved to be only suitable for the main portal vein (MPV) thrombus. PATIENT CONCERNS A 42-year-old ...
