Fig 1 (a) Mean pulmonary artery pressure (PAP) was significantly increased postoperatively above the preoperative (pre) value at 0 hours and 6 hours, and on postoperative days (pod) 1, 2, and 3 (#p < 0.01; ∗p < 0.05). (b) Cardiac output did not change after pulmonary resection. (c) Total pulmonary vascular resistance (TPVR) was significantly increased from the preoperative value (∗p < 0.05). Data are the mean ± standard deviation. The Annals of Thoracic Surgery 2002 73, 1582-1586DOI: (10.1016/S0003-4975(02)03417-3)
Fig 2 (a) Mean pulmonary artery pressure (PAP) was increased postoperatively and the increase after pneumonectomy was significantly greater than after lobectomy on postoperative day (pod) 3 (∗p < 0.05). (pre = preoperative value.) (b) Cardiac output was not significantly different between the lobectomy and pneumonectomy groups. (c) Total pulmonary vascular resistance (TPVR) was significantly increased after pneumonectomy compared with lobectomy at postoperative 0 hours and on pod 1, 2, and 3 (#p < 0.01). Data are the mean ± standard deviation. The Annals of Thoracic Surgery 2002 73, 1582-1586DOI: (10.1016/S0003-4975(02)03417-3)
Fig 3 (a) Plasma A-type natriuretic peptide (ANP) concentrations were significantly elevated at 0 hours and 6 hours, and on postoperative days (pod) 1 and 3, compared with preoperative (pre) levels (∗ p < 0.05). (b) Plasma B-type natriuretic peptide (BNP) concentrations were significantly elevated on pod 3 and 7, compared with preoperative levels (∗ p < 0.05). Data are the mean ± standard deviation. The Annals of Thoracic Surgery 2002 73, 1582-1586DOI: (10.1016/S0003-4975(02)03417-3)
Fig 4 (a) Plasma A-type natriuretic peptide (ANP) concentrations were significantly higher after pneumonectomy than after lobectomy on postoperative days (pod) 3 and 7 (∗ p < 0.05). (b) Plasma B-type natriuretic peptide (BNP) concentrations were significantly higher after pneumonectomy than after lobectomy on pod 3 and 7 (∗ p < 0.05). Data are the mean ± standard deviation. (pre = preoperative value.) The Annals of Thoracic Surgery 2002 73, 1582-1586DOI: (10.1016/S0003-4975(02)03417-3)
Fig 5 Correlation between total pulmonary vascular resistance (TPVR) index on postoperative day (POD) 3 and plasma B-type natriuretic peptide (BNP) concentration at the same determination point in patients who underwent a lobectomy (a:r = 0.06, p > 0.05) or a pneumonectomy (b:r = 0.56, p < 0.01).
