Of the cohort, 24 (83%) only required one intervention. Of these 24, 15 had imaging follow up at 1 month, 13 at 3 months, 12 at 6 months, and 7 at 12 months. At 1, 6, and 12 months, 100% primary patency was seen. At 3 months, 92% primary patency was seen, as one patient developed a thrombus. Five (17%) patients required repeat intervention for narrowing/stenosis with two (7%) experiencing occlusion/thrombosis. For the three that experienced narrowing/stenosis, a 100% 6-month assisted primary patency rate was seen. Two of these patients also had imaging beyond 1 year demonstrating patency. For the 2 that experienced occlusion/thrombosis, both had 1 month imaging to demonstrate a 100% 1 month secondary patency rate. Only one patient had follow up to 12 months to demonstrate patency. Five patients had ascites, with four (80%) experiencing resolution. Fourteen patients had elevated liver enzymes, with 10 (71%) experiencing an improvement. Five patients died, with an average time of 11.2 months from time of intervention to death, due to progression of malignancy and liver transplant rejection.
Conclusion: Based on patency data, improvement in ascites, and reduction in liver enzymes, angioplasty/stent placement are effective interventions in this setting. With a larger patient cohort and adequate follow up, future analysis may assist in classifying the efficacy of angioplasty/stent placement in this setting.
