Residual inflammatory process after aortoiliac reconstructive surgery.
BACKGROUND
The aim of the present study was to investigate the inflammatory reaction and its evolution in patients who underwent a prosthetic vascular procedure. Moreover the participation of this chronic process, during the follow-up, as a promoting or a consequence of vascular injury must be discussed.


METHODS
Thirty-four patients were enrolled in the study. All patients had an aortic disease and underwent a prosthetic vascular procedure. Preoperative exclusion criteria were an emergency situation, diabetes, infection, chronic inflammatory disease, cancer and hemopathy. Postoperative exclusion criteria were the same together with abdominal complications and additional surgery during the follow-up. The inflammatory process was investigated with the measurement of blood acute phase proteins, haptoglobin, alpha1-glycoprotein acid, C-reactive protein and interleukin-6, before, immediately after surgery and several months after surgery.


RESULTS
An increase in acute phase proteins was not observed to the same extent for all the studied patients. Before the surgical procedure, chronic inflammatory process was revealed by an increase in haptoglobin (52.9 p 100) and alpha1 glycoprotein acid (52.9 p 100) whereas increase in C-reactive protein (26.4 p 100) and interleukin-6 (92 p 100) are related to an acute process. Later after surgery, the chronic inflammatory process remained but differed from the observed process before surgery only by haptoglobin (61.7 p 100) and interleukin-6 (47 p 100).


CONCLUSIONS
The presented results, observed during the follow-up of vascular surgery focused on persistent inflammatory process and the surgical procedure did not modify the time course of this process. The evolutionary disease could be considered as chronic and independent of the local effect.
