MTP8.10 Retrospective observational study of outcomes following the splenic artery angioembolisation at a tertiary HPB unit and Major Trauma Centre

Aims To evaluate the course of events post splenic angioembolisation (SAE) in patients who presented with splenic bleeding. Methods Retrospective analysis of patient records over twenty-three months (Jan 2023 – Dec 2024) was recorded. Data included mechanism, grade of injury and the outcome post embolisation. Results 32 patients underwent SAE. Of these, 12 had trauma as the cause. 11/12 were radiologically graded, with a median of 3 (range: 1-5). All 12 were successfully discharged, without subsequent operation or repeat embolisation. Only one patient was readmitted, due to an enlarging collection which required antibiotics. 13 of the patients underwent SAE for splenic artery pseudoaneurysm. 12/13 were successfully discharged and one case requiring repeat AE due to ongoing bleeding. 2 SAE were performed for spontaneous splenic rupture, with one being discharged and one subsequently requiring immediate splenectomy following AE failure. 2 AE were required post splenectomy, both discharged after. One SAE was required due to tumour encasing the splenic vein and was discharged post procedure. The remaining two were due to pancreatitis, both of whom were discharged without further intervention Conclusion Radiological embolisation of the splenic artery has been successful in ensuring a safe discharge for the majority of patients. Only two patients overall required a subsequent operation and in the context of trauma, all patients had a successful discharge without requirement for subsequent operations suggesting that repeat imaging may not be required."
