AB  - Objective: The purpose of this study was to evaluate the common locations of perihepatic fluid collections after liver transplantation, assess their complexity, and understand their natural history and clinical significance.
Materials and Methods: A retrospective analysis of 189 postoperative orthotopic liver transplant patients with a mean age 49.6 years was performed using serial CT or MRI to characterize perihepatic fluid collections. Location, size, complexity of the collections, and clinical course were evaluated.
Results: 76 patients (40%) presented with perihepatic fluid collections with a total of 116 collections. 45 pts (59%) had a one collection, 23 pts (30%) had two, 7 pts (9%) had three and one patient (1%) had four. Collections were seen in commonly seen in certain locations, with 38 (33%) in segment 5/6, 37 (32%) in the ligamentum venosum/pericaval region, 12 (10%) in the porta hepatis, 11 (9%) the pericapsular/subdiaphragmatic location, 10 (9%) along the fissure for ligamentum teres, and the remaining 8 (7%) collections in "other" less frequent perihepatic locations. The vast majority, 100/116 (86%) of all collections were simple and 95/105 (90%) of all collections resolved, decreased or stable on follow up. Collections located in pericapsular /subdiaphragmatic region were significantly more likely to be complex. Sixteen of the 116 collections (14%) were complex, and 4 of these required intervention.
Conclusions: Perihepatic fluid collections are seen in 40 % of patients after liver transplant. Fluid collections were commonly seen in certain locations, most commonly seen in a cleft between segment 5/6, the ligamentum venosum/ pericaval region, the porta hepatis, and the fissure for ligamentum teres. Collections in these locations tend to be simple by imaging criteria and rarely require follow up. Further evaluation may be warranted if collections are symptomatic, enlarging, have complex imaging features, or located in an atypical location.
