Endovascular management of ruptured abdominal aortic aneurysms: an 8-year single-centre experience.

We aimed to review our experience with the endovascular treatment of ruptured abdominal aortic aneurysm (RAAA). During an 8-year period, 69 patients with a RAAA presented to our department; 67 underwent assessment by computed axial tomography, and 2 died on arrival before any evaluation was possible. A total of 42 patients (63%) were suitable for stent-grafting, and all but 1 (c-arm failure) proceeded to endovascular repair. Of these, 27 underwent surgery with local anaesthesia; 3 did so under general anaesthesia; and a further 11 procedures were commenced with the patient under local anaesthesia and then converted to general anaesthesia. A total of 28 bifurcated and 14 aorto-uni-iliac stent-grafts were implanted. Aortic occlusion balloons were used in 2 (5%) patients. The in-hospital and the 30-day mortality rates were 36% and 41%, respectively. After surgery, 21 complications were encountered in 17 patients. Two patients required reintervention during their hospital stay (1 type I endoleak and 1 limb occlusion). During the follow-up (median 730 days [range 90 to 580 days]), the 1-year and 5-year cumulative survival probabilities were 53% (SE 7.9%) and 50% (SE 8.0%), respectively. Three reinterventions were necessary during follow-up (2 type I endoleaks and 1 graft occlusion). We conclude that endovascular treatment is feasible in the emergency setting, and the early experience is promising. Whether such an approach is superior to open surgery remains to be determined.
