[Surgical wound infection in patients undergoing extra-anatomical arterial surgery. A retrospective study].

We present a retrospective review of a series of patients from our Service submitted to surgical extra-anatomical grafts. Correlation between diverse variants and ulterior obliteration by thrombosis or infection of the surgical wounds is analyzed. The series included 133 patients surgically treated between 1986 and 1991. The studied variants were: sex, age, type of graft, the material used, length and type of anesthesia, presentation of hypotension during the surgical intervention, diabetes, platelet recount. Fourteen patients (11%) presented early graft obliteration and 15 (11%) presented an infection of their surgical wound. Only the platelet variant showed statistical differences in patients presenting infection. A high recount of platelets could be a factor risk of infection.
