An hour after the procedure, the patient developed hypovolemic shock and was taken back to the hemodynamics suite for emergency treatment. Angiography was performed once more, via puncture of the contralateral femoral artery. Retroperitoneal bleeding was detected from the posterior external iliac close to the site where the introducer had been used in the previous procedure. In response to this, a covered stent (Advanta® 7x40) was implanted to occlude the bleeding orifice while maintaining iliofemoral patency (Figure 3). An Angioseal® (8Fr) arterial sealing device was implanted at the site of femoral access, followed by a pressure dressing. The patient recovered well and at the time of writing he had been in outpatients follow-up for 3 months and was asymptomatic, and a control tomography showed good results (Figure 4).
