To evaluate the course, use of diagnostic modalities, management, and outcome of aortic thrombosis associated with umbilical artery catheterization, we reviewed 20 cases of aortic thrombosis diagnosed by ultrasonography (n = 16) or aortography (n = 4) over 4 years. Fourteen of 20 infants had severe perinatal asphyxia, suggesting that asphyxia predisposes to aortic thrombosis. Ultrasonography provided information about the size, location, and configuration of the thrombus and was useful in following thrombus size with therapy. Radionuclide renography-scintigraphy demonstrated abnormal renal function in all 11 patients scanned. Six patients with minor thrombosis (hypertension as the only sign) improved without specific therapy. Nine infants had moderate thrombosis (multiple signs but normal urine output); all survived with a variety of therapies; two were not given anticoagulant or fibrinolytic agents; three improved with heparin alone; and one had surgery without recurrence of the thrombus. Resolution of moderate thrombosis followed streptokinase therapy in two of three infants. All five babies with anuria from major thrombosis died. Hepatic infarction associated with aortic thrombosis was found in three of three autopsies.

Hepatic infarction is a rare and fatal complication associated with hemolysis, elevated liver enzymes and low platelets syndrome. It can develop into fulminant liver failure and lead to death in 16% of cases. A 25-year-old woman, with unremarkable prenatal history, was sent to gynecological emergency unit for management of severe preeclampsia at 30 weeks and 4 days of pregnancy. Initial laboratory studies revealed aspartate aminotransferase at 290 U/L, alanine aminotransferase at 193 U/L and a normal value of hemoglobin, platelets and the prothrombin time. Behind the persistence of high blood pressure despite dual therapy, an emergent cesarean section was performed. However, two days after surgery, the patient accused an epigastric pain and was subsequently noted to have developed HELLP syndrome: thrombocytopenia (77000 /ul), anemia (hemoglobin 9.1 g/dL) and worsened liver injury (aspartate aminotransferase 2809 U/L; alanine aminotransferase 2502 U/L). A thoraco-abdominopelvic computed tomography (CT) was performed, which revealed massive hepatic infarction more marked on the right lobe, by showing the existence of diffuse hypodense plaques, poorly limited, not enhanced after injection, interesting all hepatic segments. The vascular permeability of the portal and subhepatic was preserved. During the surveillance, the laboratory tests worsened (hemoglobin = 4,6 g/dl; platelets count = 20000 /ul; WBC = 26000 /ul; CRP = 340 mg/l; albumin = 16 g/l, prothrombin time (PT) = 50%). The patient received antibiotics, she was transfused by red blood cells and platelets concentrates, she also received albumin with the pleural effusion drainage. The damaged hepatic areas stayed stable in control CT and the patient gradually improved here biological test, to become normal at 11 days after delivery. Hepatic infarction is an extraordinarily rare complication of preeclampsia. The diagnosis should be suspected by noting elevated liver enzymes, thrombocytopenia and typical images of hepatic infarction on abdominal CT. Early recognition and multidisciplinary management is necessary to prevent hepatic failure and death.
