Interventional radiology procedures in adult patients who underwent liver transplantation

Figure 4 Status post deceased donor LT. Patient with refractory ascites in association with renal insufficiency and lower extremities edema 4 years after the transplant. A: DSA, cavogram showed a stenosis of IVC upper anastomosis, 12 mmHg trans-stenotic pressure gradient was measured. In the same session hepatic veins catheterization was performed showing no concomitant stenoses in hepatic vein anastomosis; B: DSA percutaneous transluminal angioplasty performed by 16-mm diameter balloon catheter; C: DSA final cavogram showed good patency of the caval anastomosis with trans-stenotic pressure gradient reduced to 2 mmHg. From 2001 to 2007, four other trans-luminal caval angioplasties were performed in the same patient. The patient is currently in good general condition after 15 mo and has avoided re-transplantation.
