2. Figure 1
Extent of SA sacrifice in each patient. Patients were divided into 2 groups according to the number of procedures (1 stage: N = 55; 2 stages: N = 35). The extent of SA sacrifice during previous procedures is represented by the yellow part of each bar. Patients with postoperative spinal cord injury (∗). One-stage procedures with HCA (hatched bars). Paraparesis developed in only 1 patient when HCA was used. SA, Segmental artery.

3. Figure 2
The number of patients in the entire cohort (N = 90) with each number of segmental arteries sacrificed. Note that more than 75% of patients required sacrifice of 12, 13, or 14 segmental arteries.

4. Figure 3
The number of patients with each number of segmental arteries sacrificed during the first and second stages (N = 35). Six patients (∗) had an abdominal aortic aneurysm repair as the first stage. SA, Segmental artery.
