Should endovascular approach be the first line of treatment for retroperitoneal bleeding with hemodynamic shock following percutaneous intervention? A case series.

Abstract

To report a series of consecutive patients that developed retroperitoneal hemorrhage (RPH) and persistent hypotension treated with endovascular approach. RPH is a rare complication of percutaneous cardiovascular interventions associated with high morbidity and mortality. The standard approach to treat this complication has been a conservative management for stable patients, and urgent vascular surgery for those with persistent hypovolemic shock. Percutaneous endovascular treatment has evolved as an alternative treatment option. We implemented a management algorithm for patients with suspected RPH and persistent hypotension which embraced systematic use of emergency endovascular evaluation and treatment following clinical assessment without the use of non-invasive diagnostic testing. We report a series of 8 consecutive patients that developed RPH with persistent hypotension. Successful percutaneous treatment was achieved in all cases with the use of a covered stent. No patient required vascular surgery. The average blood transfusion was 3.4 ± 2.7 units per patient. There were no deaths; one patient experienced acute stent thrombosis that was successfully treated via endovascular approach. At 1-year follow-up, no further events were reported. The incorporation of a standardized protocol using only clinical evaluation followed by emergency percutaneous approach without delays attributed to non-invasive diagnostic work-up showed to be feasible and associated with favorable outcomes. © 2016 Wiley Periodicals, Inc.
