Abstract:
Retroperitoneal Hematoma is a rare intraabdominal bleeding occurring in patients with low- molecular weight heparin anti-coagulant therapy. We report a case of dalteparin sodium-associated retroperitoneal hematoma in a 70-year-old man with diabetic nephropathy with review of this condition in the literature. He had been suffered from type 2 diabetes mellitus and hypertension for 15 years. In July 2002, he was admitted to our hospital because of unstble angina and left pleural effusion. He was treated with dalteparin sodium and aspirin for unstable angina. On the second hospital day, he was refered to division of nephrology for diabetic nephropathy. Laboratory data on admission included white blood cell count of 4,500/mm3, hemoglobin 9.6 g/dL, platelet count 294,000/mm3, BUN 58.1 mg/dL, serum creatinine 4.1 mg/dL, blood glucose 178 mg/dL, hemoglobin A1c 5.9%, PT 13.9 sec (INR: 1.09), and aPTT 50 sec. On days 6 through 8, he had lower back pain, lower extremity pain and neuropathy, anemia and hypotension. Abdominal ultrasound showed 6 x 6 cm-sized well marginated mixed echogenic lesion in psoas muscle and fluid collection in retroperitoneal cavity. Magnetic resonance imaging (MRI) showed increased signal intensity and thickening of the right psoas muscle including 4.7 x 2.3 x 2.1 cm-sized cytic lesion and 6.2X5.3X3.7 cm-sized cystic lesion on the lateral portion of right psoas muscle in T2-weighted images. Percutaneous drainage of cystic lesion was performed by right lateral approach. Hemodialysis was begun without heparinization. Abdominal CT showed 5.5X5 cm-sized high attenuated lesion in right psoas muscle and 5X3 cm, 3X2 cm, 4.5 x 2.5 cm, 4 x 2.5 cm-sized heterogenous, slightly high attenuated lesions in the right lower abdomen and cul-de-sac in the scans with no enhancement. He was treated by conservative therapy. He recovered gradually. Patients with kidney diseases receiving low molecular weight heparin (dalteparin, enoxaparin, etc.) should be closely monitored to prevent serious bleeding complications. The possibility of retroperitoneal hematoma should be considered, whenever symptoms including lower back pain, inguinal pain, leg pain, anemia, or hypotension occured during the lower molecular weight heparin anticoagulant therapy. To our knowledge, this is the first reported case of retroperitoneal hematoma in a patient during dalteparin sodium (Fragmin(R)) anticoagulant therapy.
