Portal vein stenting combined with transcatheter hepatic arterial chemoembolization in treatment of portal vein tumor thrombus in patients with primary hepatic carcinoma / 第二军医大学学报

ABSTRACT

Objective: To discuss the clinical outcomes of portal vein stenting combined with transcatheter hepatic arterial chemoembolization (TACE) in treating portal vein tumor thrombus in the patients with primary hepatic carcinoma (PHC). Methods: Eleven PHC patients with tumor thrombus in the main branch or trunk of the portal vein were treated with stenting and TACE simultaneously (or TACE were performed 1 week later). The successful rate of the procedure, the patency of the obstruction, the complications, the mortality and the survival periods were all recorded. Results: Portal vein puncture was successfully performed in all 11 cases and successful stenting was achieved in 10 cases. Hepatic encephalopathy combined with hepatic failure was noticed in 1 patient. The median patency period after stenting was 5.7 (1-18) months. The survival rates of patients at 3, 6 and 12 months after treatment were 5/11,4/ 11 and 2/ 11, respectively. Conclusion: Metallic stent implantation combined with TACE has satisfactory outcome in treating tumor thrombus in the main branch and trunk of the portal vein in PHC patients without distant metastases.
