Heparin Reactions 1680, p155 - 2 Dec 2017 Retroperitoneal bleeding: case report A 75-year-old woman developed retroperitoneal bleeding during treatment with heparin [unfractionated heparin]. The woman, who had a history of hypertension and hyperlipidemia, complained of progressive swelling of her legs. Six weeks later, she reported nausea, loss of appetite and fatigue. She was admitted to hospital and was diagnosed with nephrotic syndrome. She was started on prednisolone with furosemide and tolvaptan. A renal biopsy was scheduled after 15 days. During this period, she received pulse therapy with methylprednisolone for three consecutive days from clinical day 5. She was started on IV heparin with titrated dosage ranging from 10000 12500 U/day on the day of admission as a prophylactic anticoagulation. It was continued until the day of the biopsy. Her active partial thromboplastin time (APTT) was 1.3 2.9 times more than the control values. On clinical day 13, she complaint of pain in right back, groin and thigh which gradually worsened over the next two days. She also developed decreased blood pressure and Hb. A huge right- sided retroperitoneal collection with extension to the ipsilateral pelvic iliac territory was observed on a non-contrast abdominal CT. Treatment with heparin was discontinued. Despite all the corrective measures, the woman’s condition progressively declined. On clinical day 16, at the time of transfer to another hospital, her Glasgow Coma Scale was E3V5M6 with a decreased BP and Hb level. A repeat CT scan demonstrated a massive retroperitoneal lesion without any seeping of the contrast material while an anteromedial displacement of the right kidney was observed as seen previously. She underwent exploratory laparotomy and a haematoma with partially liquefied blood clots was surgically removed without apparent bleeding. Her post-operative recovery was uneventful. The pain in the right groins and thigh gradually resolved with favourable improvement in her general condition. On clinical day 33, a renal biopsy was performed and her nephrotic syndrome was attributed to minimal change disease. On clinical day 164, a repeat CT scan exhibited resolution of the retroperitoneal haemorrhagic lesion.
