According to the treatment methods, the patients were divided into the carotid angioplasty stenting (CAS) group (n=45) and the CEA treatment group (n=45). The therapeutic effects of the two groups were observed, and the differences of coagulation function and quality of life between the two groups before and after treatment were compared. \u0000 \u0000 \u0000Results \u0000The effective rate of treatment in the CEA treatment group was 97.78%, which was significantly higher than that of the CAS group (χ2=4.939, P=0.026). The two groups had no difference in coagulation function before treatment. After the treatment, the levels of activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and D-dimer (D-D) in the CEA group were lower than those in the CAS group (t=22.801, 3.752, 6.039, 169.556, P<0.05). There was no difference in the quality of life between the two groups before treatment. After treatment, the quality of life of the CEA treatment group was higher than that of the CAS group (P<0.05).

At present, the pathogenesis of NFPA is still unclear, thus there is no effective medical management for the disease. Although transsphenoidal surgery is the first-line treatment for NFPA, it is very difficult to achieve a cure effect. It has been found that the abnormal expression of cyclooxygenase-2 (COX-2) affects the survival and progression of cancer. Recent studies have detected the expression of COX-2 in pituitary tumors, and the expression of COX-2 in NFPA is stronger, suggesting that COX-2 may be involved in the occurrence and development of NFPA.
