“…Eight definite spinal complications (11.4%) were observed in this series, a rate that is close to that recently published by St Mary's hospital (10%). 18 In this study, these complications were mainly observed in patients with an extended aneurysmal lesion and in whom extensive treatment of the thoracoabdominal aorta had been performed. Paradoxically, however, some patients treated for extensive lesions experienced no spinal complications, which is further evidence, as previously observed by Donas et al, 22 of the importance of hemodynamic factors in the incidence of these complications.…”
