Postoperative characteristics of chronic thromboembolic pulmonary hypertension (CTEPH) patients with and without collaterals
| Characteristic | CTEPH patients with collaterals (n = 28) | CTEPH patients without collaterals (n = 208) | P |
|---|---|---|---|
| Total circulatory arrest time, minutes | 50.0 ± 21.3 | 47.2 ± 18.1 | 0.48 |
| Mean PAP, mmHg | 21.0 ± 7.0 | 24.1 ± 7.0 | 0.03 |
| PVR, dyn-s/cm5 | 189.9 ± 64.2 | 233.7 ± 117.4 | 0.05 |
| ΔPVR, % | 60.6 ± 19.6 | 53.5 ± 27.2 | 0.19 |
| Reperfusion injury | 3 (10.7) | 34 (16.3) | 0.16 |
Note
Data are no. (%) or mean ± SD and were compared with the χ2 test or the independent-sample t test, respectively. Boldface type indicates statistical significance. PAP: pulmonary arterial pressure; PVR: pulmonary vascular resistance.
