Outcomes after interventional radiology (IR) or open aortic repair (OR) outcomes of patients with lower extremity malperfusion syndrome (LE-MPS) or nonmalperfusion syndrome (non-MPS)
| Outcome | All patients (N = 538) | LE-MPS (n = 26) | Non-MPS (n = 512) | P value |
|---|---|---|---|---|

| Tamponade | 9 (1.7) | 0 (0) | 9 (1.8) | 1.0 |
| Postoperative MI | 6 (1.1) | 1 (3.9) | 5 (1.0) | .26 |
| Atrial fibrillation | 178 (33) | 8 (31) | 170 (33) | .80 |
| New-onset CVA | 35 (6.5) | 0 (0) | 35 (6.8) | .40 |
| New-onset paraplegia | 1 (0.2) | 0 (0) | 1 (0.2) | 1.0 |
| Sepsis | 8 (1.5) | 1 (3.9) | 7 (1.4) | .33 |
| Pneumonia | 79 (15) | 5 (19) | 74 (14) | .57 |
| Reintubation | 33 (6.1) | 3 (12) | 30 (5.9) | .21 |
| Tracheostomy | 15 (2.8) | 2 (7.7) | 13 (2.5) | .16 |
| New-onset acute renal failure | 56 (10) | 3 (12) | 53 (10) | .74 |
| Requiring new dialysis | 21 (3.9) | 0 (0) | 21 (4.1) | .62 |
| Total LOS (d) | 10 (7, 16) | 12 (6, 24) | 10 (7, 16) | .52 |
| In-hospital mortality | 40 (7.4) | 8 (31) | 32 (6.3) | .0003 |
In the LE-MPS group, any complications after IR procedures or OR were recorded as outcomes. In the non-MPS group, any complications after OR were recorded as outcomes. Values are presented as median (interquartile range) for continuous variables and number/total number (%) for categorical variables. P value <.05 is statistically significant. MI, Myocardial infarction; CVA, cerebrovascular accident; LOS, length of stay.
