Endovascular treatment of spontaneous extraperitoneal haemorrhage: Immediate and long-term clinical efficiency

Purpose: This study aimed to evaluate the effectiveness of transcatheter embolisation in the treatment of spontaneous extraperitoneal haemorrhage (SEH). Materials and methods: We retrospectively evaluated the technical and clinical success in terms of immediate and long-term mortality in a series of patients who underwent endovascular treatment of SEH from January 2005 to December 2010. A statistical comparison of pre- and postoperative transfusion requirements was performed by using the Student's t test, with statistical significance set at p < 0.005. Results: In the period considered, 30 patients (16 women and 14 men; mean age, 73.3 years ±15.6) with SEH underwent endovascular treatment. Technical success was obtained in all cases (100 %), and a statistically significant reduction in blood transfusion requirements was observed (mean preoperative requirement: 7.5 U/day ±3; mean postoperative requirement 2.8 U/day) (p < 0.005). We observed a postoperative mortality of 10 % (3/30 patients) and mortality at 6 and 12 months was 14.8 % (4/27 patients) and 26 % (6/23 patients), respectively. Conclusion: According to our experience and to the literature, transcatheter arterial embolisation represents the treatment of choice in patients with SEH, as it ensures complete therapeutic success.
