BACKGROUND: The aim of this study was to evaluate efficiency of embolotherapy in management of retroperitoneal bleedings. METHODS: A total of 16 patients with retroperitoneal bleeding who underwent angiography followed by transcatheter embolization within a 4-year period in a single centre were reviewed retrospectively. Electronic charts as well as procedural reports were reviewed to assess immediate angiographic findings and results of embolization. RESULTS: Computed tomography was carried out in eight patients. All computed tomography scans showed retroperitoneal haematoma. In addition, contrast material extravasation consistent with active bleeding was seen in two patients and pseudoaneurysm in one. In the remaining eight patients, diagnosis of retroperitoneal bleeding was established based on combined ultrasound and clinical findings. The technical success rate for selective embolotherapy was 100%. Five of these 16 patients (three women and 13 men) had lumbar artery injury; 10 patients were associated with renal artery injury and one had bilateral internal iliac artery injury. Angiography showed active extravasation, pseudoaneurysm and arteriovenous fistula. For embolization, coils were used in six patients and N-butyl-2-cyanoacrylate in the remaining 10 patients. Four patients died within 1 month of embolotherapy. CONCLUSION: Transcatheter embolotherapy appears to be a life-saving, safe and effective treatment for retroperitoneal bleedings that may be carried out in emergency situations in haemodynamically unstable patients.
