The influence of selected demographic factors and wound location on the concentration of vascular endothelial growth factor (VEGF-A) in the wound healing process after neurosurgery: brief report.

The main aim of the work was to estimate the influence of selected demographic factors and wound location on the concentration of the vascular endothelial growth factor (VEGF-A) in patients after neurosurgical operations. The study included 20 adult patients who received a surgical treatment because of degenerative spine changes. Measurements of the concentration of the VEGF-A in the patients' blood serum were taken three times (the first time--before the operation; the second time--during the first 24 hours after surgery; and the third time--between the fifth and the seventh day after the operation). No statistically significant correlation between the concentration of VEGF-A in the patients' blood serum before and after the operation was noted. A statistically significant correlation between the concentration of VEGF-A in the individual measurements was found. It can be concluded that people with a higher concentration of VEGF-A before surgery obtained a higher concentration of VEGF-A in the measurements taken after the operation. There is a statistically significant link between the patient's age and the concentration of VEGF-A during the immediate postoperative period (the older the patient, the higher the level of VEGF-A is observed).
