Based on postoperative CTA reports, the proportion of patients with pleural effusion was 76.66% in the PRP group and 83.99% in the non-PRP group (OR = 1.59, 95% CI: 1.04–2.45, P = 0.028); the proportion of patients with pericardial effusion was not significantly different (71.43% in the PRP group vs. 70.11% in the non-PRP group, P = 0.729) (Table 4).
