RESUMEN
Objective To retrospectively evaluate the MR and CT features of delayed complications of hepatic rupture and clinical management.Methods Delayed complications developed in 8 of 20 patients with hepatic rupture 1～3 weeks after surgery.7 patients were managed with PTD and one with laparotomy.MRI and CT were followed-up before and after treatment.Results Delayed complications included 3 bilomas,3 recurrent bleedings and 2 abscess,which appeared characteristic bi-directional changes of the signal intensity on T 1-weighted image and were non-specific on T 2-weighted image(hyperintense)and CT (low-density).Conclusion T 1-weighted images appeared to be more effective than T 2-weighted images and CT in the differentiation of delayed complications from subacute intrahepatic hematoma.Followed-up MRI and CT are needed in patients with deeptype hepatic rupture in the first month after injury.PTD and laparotomy are helpful in management of biloma and abscess and nonuseful in patient with inactive recurrent bleeding.
