Evaluation of the Microcirculation in Chronic Thromboembolic Pulmonary Hypertension Patients: The Impact of Pulmonary Arterial Remodeling on Postoperative and Follow-Up Pulmonary Arterial Pressure and Vascular Resistance
Fig 5
The relationship between the extent of remodeling of the pulmonary arteries and veins.
(A) The mean PV score had a significant positive correlation with the mean obstruction ratio (n = 17, r = 0.657, p = 0.005). (B) In the high-obstruction group, the % PV score 3–4 (the fraction of all pulmonary veins with moderate-to-severe alternation) were significantly high compared with the ratio in the low-obstruction group (p = 0.01, analyzed by Wilcoxon’s signed-rank test).
