A lower levels of haemoglobin concentration were linearly associated with the diameter of the afferent arteries in the ruptured lesions (P = 0.029); B, C in the haemoptysis and haemothorax groups, PaO2, SaO2, haemoglobin concentration, and leukocyte count increased after therapy (P = 0.004, P < 0.001, P = 0.009, and P = 0.048, respectively in the haemoptysis group) (P < 0.001, P < 0.02, P = 0.003, and P < 0.001, respectively in the haemothorax group); D0 = the day when embolotherapy was performed; D2 = two days after embolotherapy; PaO2 = partial pressure of oxygen; SaO2 = arterial oxygen saturation; D Kaplan–Meier analysis for overall survival. The mean survival time was 3.2 ± 2.5 years, ranging from 7 months to 10 years
