The changes of plasma VEGFin cerebral arteriovenous malformations / 实用医学杂志

ABSTRACT

Objective Todetectthe level of plasma VEGF before and after treatment of arteriovenous mal-formationpatients,and the pathophysiological role of VEGF in arteriovenous malformationpatientswas also studied. Methods The blood samples of 17 arteriovenous malformation patients were collected according to the following three groupsgroup before operation(AVM),group 24 hours after operation(AVM24h)and group 30 days after operation(AVM30d).As a control(Con),22 blood samples were collected from lumbar laminectomypatients.The level of plasma VEGF was determined by ELISA assay. Results Compared with the control group,the plasma VEGF was significantly decreased in AVM group and AVM24h group(P < 0.05),while the plasma VEGF in AVM30d groupwas similarto that of the control group. Conclusions Abnormal blood vessel plays an important pathophysiological role in cerebral arteriovenous malformation,and the metabolism of VEGF is involved in the pro-cess of arteriovenous malformation.
